Green banks “provide financing and technical assistance for clean energy and climate solutions” while driving “economic, health, and environmental benefits for communities across the country” (US Green Bank 50). They attempt to spend, save, and invest people’s money conscientiously so they “can grow [their] money while making the world a better place” (GreenFi). 

Background

The fossil fuel industry is the primary driver of our climate crisis, creating an imperative to implement reductions of greenhouse gas as soon as possible to minimize the potential for catastrophic impacts. Unfortunately, traditional banks have exacerbated this problem; specifically, they have “financed fossil fuels by $7.9 trillion dollars since the Paris Agreement,” enabling the building of new oil and gas pipelines, large-scale equipment purchases, and more oil and gas explorations to expand their businesses (Rainforest Action Network). 

Advantages of Climate-Friendly Banks

Green banks pledge to never fund projects involving fossil fuels. Many also donate a percentage of the monthly amount that customers pay to “non-profits that support climate action” while providing transparency about the carbon footprints of their funded businesses (GreenFi). Some “optimistic studies even estimate that [this] divestment [of resources]… can lead to an effective reduction in carbon footprint of up to 7%” (Mieux Donner).

Drawbacks of this Solution

However, critics argue that the impact of divestment is not equal to the carbon impact of the investment: “under the current system, divested funds can be quickly replaced by other investors, which limits the direct effect on the behaviour of companies and their CO2 emissions” (Mieux Donner). Companies can also adjust their financial strategies to offset the impact of divestment, which limits its effect on their emissions. Specifically, while green banking is well-intentioned, staying with a conventional bank may allow customers to save more money, which they could then donate to high-impact environmental nonprofits.

Guest’s take

Charley Cummings, the CEO of a climate-friendly bank known as Walden Mutual, emphasizes how the largest funders of fossil fuel companies are banks in the United States. He encourages listeners to switch to greener banks that divest their funds towards sustainability while remaining as reliable as traditional banks.

Traditional drilling for crude oil contributes an immense amount of pollution to the Earth’s atmosphere. A study conducted by Stanford University in 2018 found that “on average, oil production emitted 10.3 grams of emissions for every megajoule of crude.” In 2022, 11.89 thousand barrels of crude oil were produced in 2022—or around 69 million megajoules. This oil is used, in part, to fuel aviation, which overall, as of 2018, contributed to 2.5 percent of all carbon emissions. Further, aviation has broader climate change implications due to the release of “contrails, NOx, water vapor, sulfate aerosol gases, soot, and other aerosols.” While this is a relatively small amount compared to other contributors—such as ground vehicles—airlines have attempted to combat their contributions to the climate crisis through integrating more sustainable aviation fuel (SAF) into their oil supply. SAF is fuel made from sources including corn grain, algae, agricultural and forestry residues, solid waste and dedicated energy crops. It has been found to have “fewer aromatic components than kerosene”—the typical jet fuel—which allows them to reduce emissions of contributors other than CO2. 

Recently, the used cooking oil from restaurants has become another valuable source for airlines to find SAF. In May 2022, Dallas-Fort Worth airport partnered with Neste, an oil refining company, to collect the oil used in onsite restaurants—including 5 McDonald’s locations—to convert used fry oil to airline fuel. Neste’s subsidiary, Mahoney Environmental, takes the used up oil from restaurants to convert the oil. It currently collects from 90,000 businesses in the United States, and is one of hundreds of companies that collect oil from various restaurants around the globe. In 2023, the first transatlantic commercial flight fueled 100 percent by SAF traveled from London’s Heathrow airport to New York’s JFK airport. 

According to the Washington Post, the cooking oil moves through an intense process to convert it into aviation fuel; first, the grease is maintained at 140º during transit to keep its liquid consistency. Then, Neste uses a clay substance to strip out unwanted chemicals, including “sodium left over from salty foods, phosphorus and various metals.” A catalyst removes the oxygen molecules, and the “straight hydrocarbon chains are bent into spiky, irregular branches that won’t stack up and lump themselves into a solid, even at very low temperatures.”

While SAF and used cooking oil help with minimizing emissions of certain fossil fuels and particles, they do not minimize emissions of CO2. Also, critics have accused SAF in airline emissions as being a greenwashing scheme, arguing that the crops used to create SAF would be better put to use by growing food. Finally, according to the World Economic Forum, “sustainable aviation fuel currently costs around four times as much as conventional jet fuel,” resulting in low incentive to replace traditional fuel production pathways with SAF. 

According to Dr. Colin Murphy, our guest for this week, policy pathways and airline incentives can encourage SAF usage.

Green Silicon (GSV) Valley is a nonprofit organization founded and led by Wilcox High School students Ayush Garg, Dev Shah and Abhi Tenneti that aims to make environmental education more accessible and personal, while also training future climate leaders on climate education. GSV seeks to realize its mission by creating hands-on kits for elementary and middle schoolers to learn about climate phenomena and solutions, and sending high school students to present classes and sessions. Through this process, they are able to spread climate education to younger generations, while also helping high school students learn how to communicate about climate issues. This helps prepare future generations of climate leaders, as well as instilling an early understanding of the importance of climate work.

According to co-founder Ayush Garg, the project arose from the business club when Garg, Shah, and Tenneti were awarded a $5,000 grant from Silicon Valley Power which allowed them to conduct six presentations at Peterson Middle School (Green Energy Futures). Each presentation includes hands-on activities such as building wind turbine models, creating water filtration systems, and running erosion experiments to help depict different climate topics. According to GSV, they have managed to reach 680 students so far across 12 partner schools in 4 different countries (Green Silicon Valley). Shah says that GSV is seeking to expand its reach to more high school chapters and partner elementary schools across the Bay Area. 

As GSV grows, it will likely run into issues with obtaining sufficient funding to carry out its goals. According to Shah, “It's gonna be a lot harder to fund international and national presentations. That's definitely the hardest part right now, where we have the volunteers, we have the teachers, we have the students, but we just need the funding for the kids.” Further, the project has run into some issues making its way into classrooms, with conflicting schedules and curriculum. GSV is accepting donations, volunteer and intern applicants, and presentation requests in order to continue expanding.

Methane is one of the most powerful drivers of near-term global warming, and also one of the fastest opportunities to slow it down. In this episode of Climate Break, we explore how a global network of states and provinces is working together to reduce methane emissions through shared knowledge, technical assistance, and peer learning. Ethan Elkind speaks with Shivani Shukla, a methane research fellow at UC Berkeley, about the Subnational Methane Action Coalition (SMAC) and how subnational governments can play an outsized role in addressing this urgent climate pollutant.

Why Methane Matters

Methane is a colorless, odorless gas responsible for nearly one-third of current global warming. Over a 20-year period, methane traps roughly 80 times more heat per molecule than carbon dioxide. Its climate impact is further amplified by the way it contributes to the formation of tropospheric ozone and adds water vapor to the stratosphere, increasing its overall warming effect.

Unlike carbon dioxide, methane comes from a relatively limited set of sources. Major contributors include landfills and wastewater facilities, agriculture (particularly livestock digestion and rice cultivation), and fossil fuel systems such as oil, gas, and coal operations. Because these sources are concentrated and well understood, methane reductions are often technically feasible and cost-effective, especially when captured methane can be repurposed as fuel.

The Subnational Methane Action Coalition (SMAC)

Launched at COP28 in 2023, the Subnational Methane Action Coalition is a global network of state and provincial governments working to reduce methane emissions. SMAC began with 15 founding members, spearheaded by California, and has since expanded to include dozens of subnational governments and observers worldwide.

SMAC is supported by researchers at UC Berkeley’s Center for Law, Energy & the Environment, which provides participating governments with technical assistance on methane inventories, policy design, and action planning. The coalition also connects members with experts, data partners, and peer jurisdictions that have implemented successful methane reduction strategies.

Climate policy is often designed and implemented at the national level, but states and provinces frequently have direct jurisdiction over major methane sources, including waste management, agriculture, and energy infrastructure. Subnational governments are therefore uniquely positioned to pilot solutions that can later be scaled nationally or replicated elsewhere.

Through SMAC’s peer network, members can share lessons learned, adapt policies to their regional contexts, and avoid duplicating efforts. A state that has developed an effective approach to reducing agricultural methane, for example, can share that model with other regions facing similar challenges.

Upsides to SMAC

One of SMAC’s key strengths is its emphasis on capacity-building. Many subnational governments (particularly those with limited resources) lack the technical expertise or staffing needed to design and implement methane mitigation programs. SMAC addresses this gap by offering tailored technical support, expert-led webinars, and communities of practice focused on specific methane sources.

Methane mitigation also offers strong near-term climate benefits. Because methane dissipates from the atmosphere more quickly than carbon dioxide, reducing emissions can slow warming almost immediately. In many cases, methane solutions are relatively low-cost and non-repetitive, involving infrastructure upgrades or operational changes rather than ongoing behavioral shifts by individuals.

Challenges in SMAC

Despite its promise, SMAC faces several challenges. Political turnover can disrupt momentum, as changes in leadership may shift climate priorities or reduce ambition. Sustained funding is another barrier, particularly for jurisdictions that need upfront investment to implement methane reduction technologies.

There is also an important broader critique: focusing heavily on methane should not come at the expense of long-term carbon dioxide reductions. While methane mitigation is a powerful short-term strategy, CO₂ remains in the atmosphere far longer and continues to drive warming over centuries. SMAC does not frame methane reduction as a replacement for CO₂ action, but rather as a complementary strategy within a broader climate portfolio.

Shukla’s Take

Shivani Shukla emphasizes that SMAC is fundamentally about collaboration and shared learning. By connecting subnational governments across regions and sectors, the coalition helps members overcome technical and capacity constraints while fostering leadership on methane mitigation. She also highlights the global nature of methane pollution and the importance of cross-border cooperation to address it effectively.

Native seed restoration aims to restore degraded ecosystems that sequester carbon, such as wetlands and riverbanks. Restoration increases climate resilience by re-establishing native plants adapted to local conditions, making landscapes more resistant to drought or fire, and strengthening overall ecosystem stability by increasing biodiversity. Heritage Growers is a California-based non-profit that has taken on this challenge, helping restore more than 20,000 acres of natural habitat statewide since its founding.

Diving Deeper

Heritage Growers was born from another habitat restoration project, River Partners. As River Partners grew, employees realized that the company was not always able to obtain “regionally appropriate” seeds for restoration projects, and, thus, Heritage Growers was created to fill this gap and help River Partners obtain seeds. Heritage Growers operates out of a 160-acre farm in Colusa, where plants are cultivated to “amplify” their genetic suitability to local conditions. Additionally, all seeds are of “known genetic origin,” meaning that Heritage Growers know where the seeds came from, and can ensure that they are locally-adapted and grown in California.

Heritage Growers’ process is labor and time intensive. The seeds often cannot be grown immediately or in bulk, so “seed specialists travel to scout the land for native seeds,” collecting part of what they find in the wild (Haas). The seeds are cleaned by hand, and tested in labs to determine quality. Finally, they can be grown under precise conditions, and harvested at the perfect time. Some seeds must be hand-picked, while others, like milkweed favored by monarch butterflies, can be over $1,000 per pound to produce.

One of Heritage Growers’ most significant achievements includes the “cultivation of 40,000 plants and 1,500 pounds of locally-adapted seeds for the historic Klamath River restoration.” For this specific restoration strategy, Heritage Growers planted the Klamath River banks with milkweed and other pollinator plants to promote biodiversity after “the largest dam removal project in US history.” 

Benefits

Native plants are vital to ecosystems because among many things, “they provide nectar for pollinators including hummingbirds, native bees, butterflies, moths, and bats” (Audubon). Additionally, the flora is a shelter for many types of fauna, while also acting as an important food source for them (Audubon). On top of this, native plants require much less water to plant and maintain than their exotic successors, which are often unsuited to the climate conditions in a given area. 

Heritage Growers also collaborates with Native Californian communities, who have centuries-long histories of tending the land. The company works to integrate traditional ecological knowledge into their land cultivation efforts. Recently, it has worked with the Yurok tribe in Northern California to ensure the primary plant growth on a restored riverbank was native plants, not weeds. Heritage Growers also says that, unlike other companies that heavily guard genetic information, the non-profit is part of an effort to expand access to native plant information to encourage an increase in native seed restoration.

Potential Issues

One issue with the process that Heritage Growers employs is that the recultivation of plants is extremely time intensive, sometimes taking years to obtain the correct quality and quantity. Additionally, native seeds are expensive to obtain even before cultivation works to increase the supply. and it is likely that climate-related variables like droughts, heat waves, and invasive species can affect the growth of the seeds. On top of this, there is limited infrastructure to produce enough native seeds at scale. Specifically, “the rising demand for seeds far outpaces the available supply” and there is simply not “enough wildland seed available to restore the land at the rate that the state has set out to” (The Guardian).

Reynold’s Take on the Future of Native Seed Restoration

Reynolds emphasizes the importance of native plants in helping landscapes become more resilient to extreme weather conditions, benefit our food systems, and sequester carbon. He suggests that individuals support this initiative by planting native species in their own backyards as opposed to exotic plants.

Seaweed is a crucial part of ecosystems in several parts of the world, including our local California coasts. However, seaweed does more than just offer a home to local marine life. It also has immense carbon sequestration potential, and contains helpful compounds for a variety of different products. Because of these potential benefits, a new industry has arisen: aquaculture. This term refers to farming in the ocean, specifically of seaweed, in order to harness the valuable resources that can be derived from the plant. 

Seaweed can be a more environmentally friendly way of growing food as it does not require the use of fertilizer, pesticides, freshwater, or land. According to The Nature Conservancy, global food production accounts for 80% of land degradation, 70% of freshwater use, and 33% of greenhouse gas emissions. Because of its lessened need for land resources, seaweed farming reduces these negative impacts on the environment. It also grows rapidly, and can be harvested in as little as six weeks. It also works as an underwater carbon sink, and can take in huge amounts of carbon, nitrogen, and phosphorus, helping to clean the oceans and reduce the risk of dead zones—areas where nutrients from fertilizer cause low oxygen levels in water due to runoff and prevent life.

While farmed seaweed is not a new concept—it has roots in coastal economies, cultures, and diets, particularly in Asia—the industry has grown to become a $16.7 billion market. Two of the companies that have stepped in to harness the power of seaweed include Ocean Rainforest and Altasea. According to Ocean Rainforest, their mission is to “use science, innovation and expertise to apply sustainable methods to grow and harvest seaweed and process it into premium quality products for our target customer segments.” The company cultivates seaweed in the North Atlantic and the Pacific Ocean, and creates products including biostimulants, pet feed, skincare serums, and ingredients for restaurants. 

AltaSea operates their farms at the Port of Los Angeles, and “is dedicated to accelerating scientific collaboration, advancing an emerging Blue Economy through business innovation, and job creation, and inspiring the next generation, all for a more sustainable, just, and equitable world.” On top of selling seaweed related products and services, AltaSea also focuses on conducting research and creating programs that immerse children and adults in ocean education. 

One potential challenge the seaweed industry is facing is the fight for space on the coastline, between commercial shipping companies, military vessels, oil platforms, and wildlife protected areas. Also, there is always a risk to altering an ecosystem, even in the case of aquaculture. Space and ecosystems still must be cleared for seaweed farms, which might have consequences for the surrounding areas. In order for seaweed farming to make an impact, it will be crucial for California policies to align with the needs of aquaculture, including space for farms along the coast. Further, Ocean Rainforest and AltaSea are both engaging in outreach projects to promote sustainable aquaculture and seaweed products to hopefully spread the popularity of their eco-friendly products and processes.

As the effects of anthropogenic greenhouse gas emissions become increasingly well understood, researchers like Dr. Peidong Yang at UC Berkeley are developing technologies that address human-caused climate change with a nature-based approach. Dr. Yang’s artificial leaves capture sunlight and carbon dioxide and produce C2, a key precursory ingredient in the production of many everyday items. 

Diving Deeper 

Though synthetic fuels have been manufactured for over a century - by combining carbon monoxide and hydrogen - these new structures may be able to generate fuel in a more sustainable way by harnessing solar energy. The artificial leaves produce ethylene and ethane, showing that artificial leaves can create hydrocarbons; previously, similar structures have only been able to separate water into oxygen and hydrogen. 

A few innovations make this process possible. One is the catalyst, a microscopic copper structure, flower-like in appearance. According to another scientist working on the project, Virgil Andrei, the copper nanoflowers can be adjusted, based on the desired outcome: “Depending on the nanostructure of the copper catalyst you can get wildly different products.” Another innovation occurs on the side of the device opposite the nanoflowers - 

Benefits 

The benefits for climate change are two fold. First, these artificial leaves can remove CO2 that’s already been released into the atmosphere by mimicking what natural leaves do through photosynthesis. These artificial leaves uptake CO2 from the air, and use it to make all sorts of different chemicals that can be utilized to create fuel. 

The second major benefit is this technology is an opportunity to revolutionize the current chemical industry. Right now, the chemical industry is powered by fossil fuels converted into the liquid fuel that powers our society. Instead, this artificial photosynthesis allows scientists to create those same very useful chemicals from the CO2 being uptaken by the artificial leaves without any added emissions in the process. Though the carbon will be reemitted once this fuel is used, it works out to be a net carbon-neutral system because the cycle continues—the artificial leaves will reuptake this CO2 as well. So, this net carbon-neutral system is drastically better than the current fossil fuel based system driving our climate crisis. 

Issues of Scale

Though this artificial leaf technology is promising for a number of future applications, it’s not ready to be scaled yet. Though the trial system worked, it’s just one step towards developing a commercially viable product. Another scientist, Yanwei Lum, emphasizes that, “The performance is still not sufficient for practical applications.” Once the leaves’ durability and efficiency is improved, they will be adoptable for fuel production. Andrei is optimistic that this step forward could come in the next five to ten years. 

Yang’s take on the future of Artificial Leaves 

Currently, the costs and energy needed for the technology are relatively high just because of how new it is. But Yang is confident that they will be able to bring the costs done, as well as the energy needed for the actual chemistry to happen. He also notes that for this to actually revolutionize our fuel production, this technology needs to be implemented at a massive scale. He hopes to see policies mandating new carbon capture technology in the conversion industry down the road.

Air transportation is a major contributor to the fossil fuel economy: studies have shown that aviation is responsible for 3.5 percent of all drivers of climate change from human activities. Planes use immense amounts of kerosene—a flammable liquid used as fuel—in order to travel. When kerosene burns, it releases greenhouse gases like carbon dioxide and black carbon. Also, planes create contrails: “line-shaped clouds produced by an airplane’s hot engine exhaust interacting with cold humid air several miles above the Earth’s surface.” These are the lines of white you see behind a plane as it flies overhead: small water particles from the plane’s engine exhaust that have frozen to become visible ice crystals. Because these are essentially clouds, when they persist past a short period of time, they have the potential to trap heat in the atmosphere, leading to a warming effect with many negative climate change consequences.

Advanced Air Mobility as a Climate Solution

In order to combat these negative effects of air travel—and to keep up with increasing demand for shorter distance air travel—researchers have begun looking toward opportunities for low emission options that can be more widely applied. This concept has been coined Advanced Air Mobility (AAM), and seeks to develop transportation technologies which are: “highly automated, electrically powered, and have vertical take-off and landing capability.” One main goal of the project is to develop Urban Air Mobility (UAM) in order to connect underserved communities within cities and rural regions.

Ideally, Advanced Air Mobility will be an environmental improvement because it will use cleaner forms of energy to fuel the transportation, from electricity to hydrogen. According to Adam Cohen of UC Berkeley’s Transportation Sustainability Research Center, there are several different potential uses for the cleaner energy technology, including air taxi services, small package delivery, emergency services, or aeromedical use cases. Airports in particular are confronting a lot of demands for power—both in terms of aviation and ground vehicles—which electric fueled AAM may be able to help fulfill. In terms of hydrogen power, Cohen says manufacturers are testing and have prototypes for a hydrogen aircraft in the hopes that hydrogen will be an entry point for more sustainable flight in the future.

Challenges of Implementation

AAM is still in its early stages of development, and has yet to be implemented in a real way. In order for this to occur, its innovators need to place safety and integration at the forefront, ensuring passenger and cargo safety, as well as minimal disruption to current air traffic pathways. Further, it will be necessary to ensure some level of equitable access in terms of both convenience and cost across groups of people. Ultimately, AAM hopes to be a step in the direction toward clean energy in the aviation sector, encouraging policies and technologies in line with sustainable goals.

Across the United States, evangelical Christians are increasingly forging a connection between faith and climate action by redefining environmental work as a sacred duty to care for God’s creation. By understanding sustainability through the lens of biblically mandated stewardship, more and more Christians are discovering renewed hope and purpose in addressing climate change.

What Is Creation Care?

To many evangelical environmentalists, caring for the Earth is not a political act. Rather, it is a spiritual duty. They believe that how we treat the planet should reflect how God treats us: with compassion, responsibility, and reverence. That means resisting the exploitation of natural resources and instead treating the Earth as a divine gift entrusted to humanity.

Historically, however, environmentalism and climate science have been viewed as controversial in conservative Christian circles, seen as secular or partisan issues. But that perception is beginning to shift, thanks in part to young leaders and faith-based environmental advocates who are reframing climate action as a moral and theological imperative.

Faith in Action

One of those young leaders is Becca Boyd, a student at Indiana Wesleyan University studying Environmental Science. Raised in a Christian home, Becca often felt her environmental concerns were dismissed and even challenged. Feeling unhead, she began to experience a crisis of faith, questioning both her faith and her place in the church.

Everything changed when she was introduced to the concept of creation care in college by her professors. For the first time, she saw how her love for the environment and desire to protect it could be an act of faith rather than in conflict with it.

A Theology of Hope

Like many young people in the climate action space, Becca has felt overwhelmed by the constant sense of “doom and gloom.” The narrative that it’s too late to fix the damage can leave people in despair and feeling helpless. But creation care offers her a more hopeful, spiritually grounded mindset. Rather than dwelling on what’s broken, Becca focuses her energy on healing what’s still possible.

For Becca, environmental stewardship is now a form of worship: small acts like conserving energy, recycling, or planting a pollinator garden at her school are ways of honoring God.  And by inviting others to do the same, she’s helping grow a climate movement rooted not in fear but in faith and hope for the future.

Choosing Words That Open Doors

Through her advocacy, Becca has learned that the language you use to talk about climate issues matters, especially in Christian spaces. The word “climate” itself can be politically charged and can trigger defensiveness, while terms like “creation care” and “eco-theology” feel more rooted in faith and shared values.

She is also intentional about her tone, making a point to avoid “you” statements. Rather than telling people what they should do, Becca shares what she does and why. This approach opens the door to conversation rather than closing it. According to Becca, it’s about meeting people where they are and establishing a common ground — inviting them in, not calling them out. 

The Challenges Ahead

Creation care is still a growing movement, and while it’s gained traction in places like Indiana, there’s still a long way to go. Climate science skepticism and misinformation continue to circulate in many conservative communities. But Becca and other young Christians are starting vital conversations in churches and on campuses, emphasizing climate change as a humanitarian issue: one that affects food security, public health, and the lives of future generations. 

She also shares resources like Cowboy & Preacher, a documentary tracing the history of Christian environmentalism, to show that this movement isn’t new, and that faith and climate action have long been intertwined. 

About Our Guest

Becca Boyd is a rising senior at Indiana Wesleyan University studying Environmental Science. She is a Climate Advocate for Young Evangelicals for Climate Action (YECA) and previously served as a College Fellow. On campus, she launched a student sustainability club and helped lead campus-wide conversations about the intersection of faith and environmental responsibility. She was recently featured in The New York Times for her work advancing Indiana’s growing creation care movement.

Historically, India has faced challenges with persistent air pollution as a result of industrial development. One key approach to combat this has been to reduce greenhouse gas emissions. For example, Indian policymakers have been pushing for the commercialization of electric vehicles which has unlocked various incentives for companies like Vision Mechatronics to develop electric vehicles run by lithium-ion batteries. 

How Lithium-Ion Batteries Power EVs

India “seeks to attain a 30% share of electric vehicles, in the total vehicles sold, by 2030” and accelerating the market for it by “moving from incentives to mandates” like a Zero Emission Vehicle policy (NITI Aayog). Taking advantage of this political support, Vision Mechatronics “aims to develop a complete domestic ecosystem around EVs” which have “zero tailpipe emissions” (Vision Mechatronics). 

Many electric vehicles are driven by lithium ion batteries which “can contain hundreds of individual cylindrical battery cells that are the same shape as common AA and AAA batteries” (Edmunds). They are extremely energy efficient and can store a multitude of energy; on full battery, electric cars powered by lithium-ion batteries can drive over 200 miles–although it may depend on the specific car model. Compared to their precursor, lead-acid batteries, lithium-ion batteries have higher energy density which increases the mileage of a car. They are also extremely lightweight and this ensures that EVs aren’t too heavy. Moreover, the electricity used to refuel the EVs come from renewable energy sources like solar power. 

The Environmental Cost of Battery Production

There are various concerns that lithium-ion battery powered cars take a long time to charge. Although this may be true for some models, recent developments have led to an increase in charging efficiency and overall energy storage. For instance, the Hyundai Ioniq 5 can be charged “from 10% to 80% in just 18 minutes” (Edmunds).

Moreover, the environmental impact that the creation of lithium-ion batteries has is detrimental as “the mining process for lithium and other materials used in these batteries can… lead to water pollution and habitat destruction” (Tara Electronics). Although this is the undeniable truth, it is promising to know that due to advancements in technology it has been shown that electric car batteries can “last 12 to 15 years in moderate climates”, meaning that they don’t have short lifespans (Edmunds). Moreover, “instead of ending up in a scrapyard like most internal combustion engines do, electric vehicle batteries can be repurposed, refurbished, or recycled when they fail” (Edmunds).

Building India's EV Ecosystem

Gupta believes that local battery production in India can help India progress towards an economy that is powered by clean energy. She mentions that it has been difficult to employ skilled labor in this field due to geopolitical tensions and a lack of awareness regarding the importance of this field. However, she is trying to bridge this gap by making opportunities in her company as accessible to the next generation as possible.

Nature is Nonpartisan is a bipartisan, solutions-focused coalition working to unite Americans around shared environmental goals. By fostering cross-party support for conservation and land stewardship, the organization hopes to reframe climate action as a unifying national priority rather than a partisan fight. 

Establishing Nature as Middle Ground

In recent years, environmental politics in the U.S. have been paralyzed by partisan gridlock, stalling climate progress. Nature is Nonpartisan aims to break this deadlock by reframing environmentalism around common-sense values, such as safety, access to the outdoors, and community well-being. By engaging Americans across the political spectrum, the coalition seeks to depoliticize climate solutions and ground them in conservation principles that resonate more universally: protecting public lands, supporting disaster-affected communities, and ensuring access to clean air and water.

This approach gained national attention in early 2025 when founder and CFO Benji Backer, alongside coalition members, briefed White House staff on nonpartisan conservation strategies. A meeting scheduled for fifteen minutes extended well over an hour, ultimately influencing President Trump’s unexpected June 2025 signing of the “Make America Beautiful Again” executive order. The order focuses on conserving public lands, safeguarding wildlife, and securing clean drinking water. Backer underscored that wildfires, drought, and ecosystem collapse don’t just affect the environment; they threaten billions in outdoor-recreation revenue and undermine the hunting, fishing, and farming traditions valued across political lines.

Nature is Nonpartisan’s narrative emphasizes that environmental protection is not only about climate, but also the American landscape, economic security, and the natural heritage millions rely on and cherish.

Conservation as Climate Action

Nature is Nonpartisan’s work centers on four key conservation areas: managing forests to reduce wildfire risk, enhancing water quality and improving water infrastructure, enhancing natural disaster resilience, and promoting responsible land stewardship. Together, these priorities offer a practical, bipartisan path to protect ecosystems and communities most vulnerable to climate change.

Overall, emphasizing conservation provides a widely palatable, bipartisan entry point into climate action. By restoring ecosystems, sequestering carbon, and protecting biodiversity, these efforts simultaneously strengthen local economies — particularly in rural regions dependent on recreation and natural-resource industries — while building long-term climate resilience. 

The Tension Beneath the Surface

Despite its promise, Nature is Nonpartisan’s work exists within a fraught political landscape. Environmentalism and conservatism are still often framed as ideologically incompatible, a perception the organization works actively to undo. While the “Make America Beautiful Again” executive order signals progress, critics argue it may be more symbolic than substantive, especially given President Trump’s longstanding dismissal of climate science. Some fear the order could serve more as a political performance than a genuine environmental advancement.

These tensions point to the broader challenge: decades of conservative skepticism toward climate science have made it difficult to ensure follow-through on policy. Nature is Nonpartisan hopes to continue confronting this distrust by reframing environmental protection around nationally shared values — family, future generations, clean water, clean air, and access to the outdoors — whether one is a Midwestern farmworker or a city resident.

The Power of Words and Bipartisan Policy

Communications Director Amelia Joy emphasizes that language is crucial to keeping these efforts genuinely nonpartisan. Because the word “climate” has become politically charged, Nature is Nonpartisan often avoids leading with it. Instead, Joy notes that many of the organization’s core priorities, from wildfire prevention to natural disaster resilience, are climate issues, but by centering them in everyday terms, the coalition can build durable, cross-party support that can outlast any single administration.

Policy Director Maya Cohn adds that progress doesn’t have to depend on who is in office. She emphasizes that policy advances can happen under any president or Congress if people are willing to work across political lines. For her, bridging divides and having honest conversations, even with those you disagree with, is the only way to create long-lasting environmental solutions.

In Indiana, evangelical churches are finding new ways to live out their faith through environmental action. With support from the Evangelical Environmental Network (EEN), congregations are installing solar panels, planting native gardens, creating nature play areas for preschoolers, and even adding electric vehicle charging stations. This initiative, often referred to by Christians as “creation care,” positions environmental stewardship and climate action as a biblical responsibility.

What is the Evangelical Environmental Network?

EEN is a biblically-based ministry and the environmental arm of the National Association of Evangelicals, dedicated to mobilizing Christians around climate action. By collaborating with churches, universities, and seminaries, the organization offers education on how creation care is a collective mission among evangelicals. In Central Indiana, this has meant congregations and Christian universities working together on eco-friendly infrastructure and community events such as Indy Creation Fest, an Earth Day-like celebration that joyfully highlights humanity’s duty to conserve and steward the beauty God bestowed on us.

Creation Care as Protecting the Poor

A central theme of EEN’s work is showing Christians that defending the poor and vulnerable also means addressing pollution — including from plastic, methane, and mercury — and climate change. Low-income communities often face the harshest impacts of extreme climate disasters, poor air quality, and contaminated water. By making this connection clear, EEN reframes environmentalism as an act of justice and compassion for humanity, aligning climate action with evangelical priorities. Their programs highlight not only environmental threats but also human health risks, from asthma linked to air pollution to the dangers of unsafe drinking water.

The Building of a Movement

Creation care is still a growing movement and remains a minority position within American evangelicalism. Some believers continue to prioritize human welfare over environmental stewardship without recognizing that the two are inseparable. Historically, evangelicals have been among the groups least likely to regard climate change as urgent and express wariness about climate science. While the visible progress in Indiana is promising, it remains only a small step in the broader effort to normalize creation care across the evangelical community. 

Nonetheless, by centering their approach on shared religious values, EEN helps evangelical Christians see climate action not as a burden, but as a natural extension of their mission to honor God and all of creation.

About Our Guest

Rev. Dr. Jeremy Summers, the Director of Church and Community Engagement at EEN, emphasizes that caring for the environment and caring for people are one in the same. He works with churches, universities, and local communities to connect biblical principles with climate action, advancing the creation care movement within evangelical circles. Within these spaces, he urges Christians to understand that protecting ecosystems is necessary to protect the people who live in them, especially those from marginalized groups who suffer most from pollution, climate change, and environmental injustice.

For over a century, native salmon populations in California have been adversely impacted by human activities such as mining, dam building, and overfishing practices, often leading to the loss of critical habitat and  decreased genetic diversity. With additional environmental stress from climate change, such as rising surface temperatures and changes in freshwater temperature and flow, salmon populations have been quickly declining. In addition, dams trap salmon into the warmest parts of the watershed, where they are more vulnerable to predators and have decreased breeding area necessary for their survival. Salmon are an incredibly important marine species, often referred to as a keystone species, as they play an essential role in the health and function of an ecosystem. Not only are salmon ecologically beneficial through their ability to disperse nutrients throughout streams and rivers, but they are also culturally significant to Indigenous people. Indigenous culture has historic ties to salmon, including reliance on the species for sustenance and livelihood. As a result, indigenous tribes have a particular attachment to and concern for salmon, and issues such as diminished water quality and the burdens brought about by climate change have a deep resonance. In order to restore salmon populations, Indigenous groups and environmental activists have advocated for increased restoration of watersheds, the reopening and improving of ecologically important areas, and the removal of dams that block natural salmon spawning habitats.  

Dam Removal as Solution to Climate Change

As climate change reduces water flows in California and increases temperatures beyond which salmon can tolerate, certain populations of salmon have become endangered species. Drastically reduced population levels have brought about a wave of concern, as their absence can disrupt nutrient cycling, reduce food availability, and negatively impact the livelihoods of people who depend on salmon for sustenance, income and cultural value. The “California Salmon Strategy” outlines actions for state agencies to stabilize and promote recovery of salmon populations. The plan envisions coordination among multiple state agencies, Tribal Nations, and federal agencies for implementation. 

In the late 19th century, treaties between Pacific Northwest tribes and federal agencies gave tribes the right to hunt, gather, and fish in “accustomed grounds” in exchange for land. However, by the mid-20th century, these agreements had largely been abandoned by the federal government, with states outlawing traditional methods of subsistence fishing. Coupled with increased development and resultant large-scale habitat loss, salmon populations have been on a steady decline. Tribal governments have long opposed the construction of dams in California, raising concerns of the devastating effects such construction has had on their way of life and the biodiversity of river ecosystems.

Therefore, one solution has been the removal of dams to allow for continual, unobstructed streams of water for salmon to move freely through. Large dams built in the early 1900s block salmon’s access to over 90% of historical spawning and rearing habitat in mountainous streams. The largest river restoration project is currently taking place on the Klamath River, located in Southern Oregon and Northern California, where dam removal is predicted to improve water quality and restore access to more than 420 miles of habitat. The lack of access to these cold waters for spawning was one of the primary reasons for the steady decline of California’s salmon population. Studies project that the removal of the Klamath Dam will reduce the river’s temperature by 2-4 degrees, which salmon prefer as cold water holds more oxygen, allowing for improved metabolism and the preservation of salmon quality, spurring new population growth.

In addition to dam removal, the California Salmon Strategy proposes expanding habitat for spawning and protecting water flow and quality in key rivers. By fostering collaborative efforts, the State of California and Tribal Nations hope to successfully restore salmon spawning habitats and reintroduce salmon through traditional ecological knowledge.

Benefits of Salmon Restoration

Salmon restoration will help restore genetic diversity, improve habitat, and foster resilience. Beyond ecological benefits, restoring salmon habitats will benefit local communities and restore their cultural significance. The removal of dams like that on the Klamath River has already been a huge success in reopening former habitat that historically supported diverse salmon populations, with significant salmon spawning showing signs of a rejuvenation of this endangered species. 

Challenges of Restoring Salmon 

Unfortunately, salmon will continue to face the threat of climate change, particularly due to the lack of cold, readily available water. Salmon’s migratory lifestyle patterns are also under threat from climate change, as a lack of cold water prevents survival at different stages of the life cycle in order to reach their spawning habitats in time. One major concern of the dam removal process is the short-term increase in turbidity and water quality problems during the removal process. There also could be the potential for disrupted habitats and short-term fish mortality due to the changing water quality dynamics. However, water quality problems usually pass after the initial slug of sediment moves downstream, allowing for long-term benefits to take hold.

While wind energy is renewable and non-polluting, the wind turbines themselves can create pollution problems. Now, scientists are creating wind turbines that can be made with less energy, but also create less waste because they can be recycled. This, of course, reduces impacts on the waste stream and provides a sustainable alternative to current wind turbines that are often extremely hard to recycle. Moreover, the new material requires less energy to create and mold into the desired output, subsequently reducing associated greenhouse gas emissions.

Making Wind Turbines with Recyclable Resin

Not surprisingly, even renewable energy resources also have environmental costs. For instance, when the life of a wind turbine ends (after about 20 years), it ends up in landfills. Moreover, as more wind farms are built and older turbines are taken out of usage, the waste burden is significant. Most resins also used in wind turbines require many nonrenewable resources and a lot of energy to produce. In addition, they do not easily degrade.

This is why researchers at the National Renewable Energy Laboratory (NREL) started developing turbines from recyclable resin. They call the resin PECAN, and it is created with “bio-derivable resources” like sugars as opposed to the type of resin that has traditionally been used, which is not bio-derived and extremely hard to upcycle. Specifically, when the wind blades are unusable they are shredded to be used as “concrete filling”, which never biodegrades, while turbines made of recyclable resin can chemically break down within 6 hours.

Benefits of Recyclable Resin 

Not only can PECAN withstand harsh weather, but it does not deform over time. Additionally, once the resin undergoes a chemical process called “methanolysis” it only takes 6 hours for the original carbon and glass to be recovered to be recycled. Moreover, the catalyst to harden the resin is also recovered and this means that it is possible for it to be used again (creating a circular waste stream). Moreover, PECAN produces “40% less greenhouse gas emissions and 30% less energy to make”.

Challenges of Implementation 

There is a general lack of awareness of solutions like PECAN which strive to make our waste stream more circular, and without that awareness, it would not be able to make the large positive impact that it is capable of making. This is also one of the reasons why right now, wind turbines made out of recyclable resin proves to be more expensive, as there is not enough of a demand for it yet.

Ryan Clarke believes that creating wind turbines from naturally occurring resources like sugars can be extremely helpful in waste reduction. Additionally, he emphasizes that larger deployment of this technology and increased awareness can lead to major cost savings in the long run.

The buildings and construction sector accounts for approximately 37% of global carbon emissions (UNEP). According to the UN Environmental Programme, much of this impact is derived from the operational aspects of buildings including heating, cooling, and lighting. However, building materials and their production also play a major role. Construction materials include cement, steel, and aluminum. Timber and wooden materials play a major role as well. According to Plantd co-Founder Josh Dorfman, “The global economy produces and transports 4.1 gigatons of concrete, 1.9 gigatons of steel, and 0.8 gigatons of timber products every year.”

The UK Green Building Council highlights that timber harvesting (logging) can be conducted with varying degrees of sustainable forest management, “from clear-cutting to regenerative forestry.” While the timber industry has been focusing on more sustainable practices, the process often leads to soil erosion, habitat loss, negative impacts on the water cycle, and potential harm to indigenous communities. Further, trees can take several years to grow and harvest.

What is Plantd?

Plantd, a startup dedicated to creating sustainable construction materials, seeks to solve this issue. The company has developed its own material: a grass species similar to bamboo and sugarcane with high fiber strength embedded into the plant itself during growth. The plant can grow on large plots of land, is ready for harvesting two to three times per year the year after it is planted, and is not subject to wildfire in the way that forests are. When the plant is harvested, the fiber can be extracted and reoriented to create a wood-like product according to different specifications with an electric press invented by Plantd. It is fully certified as a durable construction material, meeting both strength and moisture requirements. According to Plantd CEO Nathan Silvernail, “ if you take a timber-based material and you fully submerge it in water to the point where it can no longer take on any more water and you dry it out and you strength test it, it loses 70% of its strength. Our material under the same exact conditions and exposure loses only 1% of its strength.” Ultimately, with the new natural material and more efficient press, Plantd hopes to develop construction materials that are far more cost-effective and scalable. 

Potential Drawbacks

In order to overcome potential dubious consumers and encourage widespread adoption of their product, Mr. Silvernail is optimistic that the company will attract buyers with a lower price point for the product. According to Mr. Silvernail, “ Our bottom line is not counted in dollars. It's counted in tons of CO2 captured. I tell all of our investors that. So we are not sitting here trying to just make the biggest margins we can. We're trying to make an impact. And again, the only way that I'm gonna do that is through price and volume.” 

Mr. Silvernail also hopes that the government can subsidize costs for buyers to buy their carbon-negative product, allowing it to penetrate the longstanding foothold of the traditional timber industry over construction. However, many government programs aimed toward assisting sustainable companies are being cut, presenting a potential challenge for Plantd to build its market and appeal to consumers. Further, once Plantd is able to encourage demand for their product, their biggest challenge is scaling to meet demand. While they are sold out at the moment, the company is working to optimize their build processes to create enough panels to eventually sell in stores for home builders.

The  Latino Climate Justice Framework (LCJF) prioritizes environmental justice while helping to protect disproportionately affected individuals–commonly Latine people. Specifically, LCJF works with communities that “face numerous climate-related issues, from extreme heat affecting outdoor workers and poor air quality in neighborhoods near industrial facilities, to increased vulnerability to natural disasters like hurricanes, floods, and wildfires.”

The Particulars

LCJF has three areas of focus with different goals for how to better the health of the environment and the Latino community. Chapter one of the LCJF identifies how fossil fuels disproportionately expose the Latine community to toxic pollutants. LCJF believes that carbon capture methods are an extremely passive solution that do not address the problem; instead they hope to prioritize renewable energy while enhancing affordability and accessibility to these amenities by “ramping up recycling, reusing batteries and solar panels” and “ensuring equitable investment”.

The second chapter outlines how “latinos are 21% more likely than white individuals to reside in urban heat islands” and “only 19% of Latino/a/e children have nearby recreational green spaces, compared to 62% of white children.” They follow up with recommendations for how they hope that plans for “prioritizing urban greening projects in Latine neighborhoods with the highest heat risk and lowest tree canopy and green spaces” would improve air quality in their neighborhoods, while reducing health risks. 

The last chapter outlines how Latines have an extremely sacred relationship with land and water.  However, due to “patriarchal and white supremacist oppression” they have been deprived of their access to nature. Moreover, they acknowledge that Earth has been losing vital biodiversity for those very same reasons. Thus, they hope to reduce this problem by opposing efforts to extract natural gas and oil, build the US Mexico border on sensitive lands, and “sprawl development on public lands.”

The Upsides 

The LCJF aims to mitigate climate change by reducing pollution from fossil fuels through stringent regulations and promoting clean energy alternatives. It emphasizes the development of climate-resilient infrastructure to protect communities from climate-related disasters. Additionally, the framework seeks to empower Latine communities by involving them directly in environmental decision-making processes, ensuring that solutions are culturally relevant and effective.

Foreseeable Difficulties in Utilization

Though potential issues may include challenges with implementation, funding, political support, scalability, and policy adaptation efforts. LCJF Program Director Irene Burga argues that Latine people are often kept out of the conversation of climate equity despite the fact that they are extremely affected by climate change. If their voices are heard, she says, climate policies would be much more impactful.

Wheat varieties that are resilient to climate change are sometimes referred to as "chaos wheat." An initiative of King Arthur Baking Company–an emerging leader in the creation of chaos wheat–and Washington State University's Breadlab is aiming to create wheat blends, such as King Arthur's Regeneratively-Grown Climate Blend Flour, composed of unique wheat varieties bred for resilience against the unpredictable effects of climate change, including fluctuating temperatures and varying water levels. These wheat varieties are cultivated using regenerative agricultural practices that enhance soil health and biodiversity.

Chaos Wheat as Climate Solution

By focusing on breeding wheat that can withstand extreme weather conditions, the initiative seeks to ensure consistent crop yields despite environmental unpredictability. Additionally, the use of regenerative agriculture practices contributes to carbon sequestration, improved soil health, and increased biodiversity, all of which play a role in mitigating climate change. 

To create the special, “Climate Blend” flour out of chaos wheat, researchers use practices like “cover cropping and crop rotations, minimizing inputs, no/limited tillage, and affordability and accessibility of crops.” The chaos wheat collaboration with Washington State University’s Breadlab, aims to increase biodiversity, promote carbon sequestration by improving soil health, and build resilient farm ecosystems as a whole.

In the late 1800s, white bread was extremely popular due to its low cost of production at enormous scale. However, this quickly became detrimental to the environment because it led to monoculture, which reduces genetic biodiversity.  In fact, large scale bread production “emits more greenhouse gases than Russia, Brazil, and Germany combined”.

Benefits of Chaos Wheat

Chaos wheat increases genetic diversity and reduces risk of diseases and increases “resistance to drought, pests, and volatile weather, while requiring less water, fertilizer and agrochemical.” Part of the potential advantage of chaos wheat is the plants’ improved ability to deal with “‘ chaotic events.’” Currently, however, it is more expensive in comparison to standard whole wheat, “$2.98, compared with $1.12”.

The inspiration for this blend came from ancient strategies that farmers employed, for example a “mix of different species and varieties known as maslins” which are “plants [that] compete less with one another for soil resources and are diverse”. Essentially, if “they can offer 2 to 3 percent higher yields, they will be our greatest asset to increasing yields and crop resilience.”

Challenges of Implementation

Potential critiques or drawbacks of this solution include the challenges associated with transitioning farmers to regenerative practices, which may require significant changes in traditional farming methods and could involve initial financial investments. Moreover, as regenerative agriculture is currently unregulated and lacks standardized certification, defining and implementing consistent practices can be complex. Ensuring that these new wheat varieties are economically viable for farmers and acceptable to consumers in terms of taste and baking quality also presents potential challenges

There is also a tension between large scale efforts, including the King Arthur Baking Company initiative, and more local initiatives that might be “developing more sustainable and climate-resilient products” and which “keep our dollars in the local food economy” but “invest[s] in a more sustainable and resilient food economy”. This is often a difficult tradeoff.

Robin Morgan believes that chaos wheat is a  game-changer in agriculture and in the face of climate change as it reduces wheat’s vulnerability to extreme weather conditions. This means that the crops can grow in more locations and with reduced soil disruption. Moreover, he emphasizes that it increases health benefits by providing more fiber to consumers.

About Our Guest

Robin Morgan moved to Washington state to pursue a PhD at the WSU Breadlab in order to develop a perennial grain crop. He has experience ranging from the chromosomal to the field level as well as studying the history of wheat.

The Decline of Arctic Sea Ice

As climate change heightens temperatures and alters climatic conditions, summer sea ice in the Arctic is melting rapidly. By the mid 2030s, it is predicted that a “Blue Ocean Event” (or BOE) will occur, meaning that the Arctic Ocean is expected to have less than one million square kilometers of sea ice. This equates to just 15% of the Arctic’s seasonal minimum ice cover of the late 1970s. As ice continues to melt, more of the ocean will be exposed to the sun's rays, thus absorbing more heat and accelerating warming. The Arctic has warmed four times faster than the rest of the world since 1979, largely due to this positive feedback loop known as Arctic amplification. Since the 1980s, the amount of Arctic sea ice has declined by approximately 13% each decade. As the BOE unfolds, it will trigger significant impacts, including droughts, heatwaves, accelerated thawing of terrestrial permafrost (releasing emissions in the process), and sea level rise. The Arctic plays a critical role in climate stabilization by acting as a large reflective surface, helping to cool the planet and maintain a stable global temperature. The BOE is thus a major climatic tipping point with catastrophic global consequences. A new methodology has been proposed to protect and restore Arctic sea ice known as Aqua Freezing. This approach uses renewable energy-powered pumps to distribute seawater on existing Arctic ice, allowing it to refreeze and thicken, helping to maintain climatic stability.

The plan aims to target over 386,000 square miles of Arctic sea ice, an area larger than California. The process of refreezing already shows promise in field tests conducted over the past two years in Alaska and Canada. Proponents of refreezing Arctic sea ice believe that this technique would buy the region time while we make the necessary emissions cuts to curb the impacts of climate change. Refreezing ice would also preserve the albedo effect, which reflects sunlight back into space, preventing warming. 

Although AquaFreezing offers a potential solution to combat Arctic melting, scientists and policymakers doubt whether sea ice can be grown over a long enough period to make a true difference in the climate crisis. Further, the project is quite costly, equating to over 5 trillion dollars and demanding more steel than the US produces in a single year. The project would require 10 million pumps; however, this would only cover 10% of the Arctic Ocean’s roughly 4 million square mile size. To cover the entire area would require 100 million pumps and roughly 100 million tons of steel each year. The US currently produces around 80 to 90 million tons of steel a year, so covering just 10% of Arctic ice would require 13% of US steel production. The production required for the project could lead to immense environmental degradation and added emissions in the process. 

About Our Guest

Simon Woods, co-founder and Executive Chairperson of Real Ice, is hopeful that this solution will buy the region time while we make the necessary emissions cuts to curb climate change. Real Ice believes this innovative solution can preserve sea ice and thus work to combat climate change.

UC Davis researchers are examining a novel approach to combating climate change: turning our buildings into carbon sinks. The solution is based on incorporating biochar, a carbon-rich material obtained from plant material, into common construction materials like concrete, brick, and asphalt. By embedding carbon directly into long-lasting infrastructure, this approach reduces atmospheric CO₂ and also transforms one of the most carbon-intensive industries in the world into a tool for climate mitigation.

Background: How Carbon Storage in Building Materials Works

Biochar is created through pyrolysis, a process involving heating organic material, such as crop residues or wood waste, in a low-oxygen environment. This process locks in carbon that plants absorb during photosynthesis and prevents it from being re-released into the atmosphere through decay or burning.

The research team at UC Davis, headed by Professor Sabbie Miller and Dr. Elisabeth Van Roijen, proposes the use of biochar as a partial replacement for the materials in concrete and other construction compounds. Since more than 20 billion tons of concrete are produced every year by the construction sector, substituting 10% of that with biochar-based mixtures could store up to 1 gigaton of CO₂ annually, or the equivalent yearly emissions from Japan.

Unlike temporary carbon storage methods, like soil burial, embedding biochar in durable infrastructure ensures long-term sequestration, potentially spanning decades or even centuries. It also leverages the global scale of construction as a medium for climate action.

Advantages of This Solution

Apart from net carbon emissions reduction, the introduction of biochar-enriched building materials has tangible engineering benefits. It has been found that the addition of biochar can enhance thermal insulation, fire resistance, and durability in some uses. The process also fits well within the circular economy principles because of the organic waste used and reduced need for virgin materials.

Because construction is already a high-volume, resource-intensive industry, integrating biochar into existing supply chains could make climate-positive practices scalable and economically viable without requiring dramatic infrastructure overhauls. Equally important, this solution provides dual benefits: supporting both carbon sequestration and the development of sustainable materials.

Drawbacks and Critiques

The approach faces several scientific and logistical obstacles despite such a promising premise. Producing biochar requires energy in quite significant quantities, with sourcing biomass at large scales risking unforeseen ecological impacts such as nutrient depletion or habitat disruption. Some critics even ask whether its broad adoption might inadvertently encourage the removal of older buildings in favor of the construction of newer, carbon-storing ones, offsetting any climate gains.

Another factor is the life cycle of the biochar-infused materials themselves. While they can store carbon for decades, it remains undetermined how these materials at the end of a building's life are to be managed to avoid re-release of CO₂. Future policy frameworks and recycling technologies will be required to address these challenges if there is to be long-term effectiveness.

Sustainable wood refers to the use of mass timber, which involves smaller pieces of wood that are dried and glued together in a perpendicular, crosswise pattern to form large slabs. This process can incorporate a closed-loop system that repurposes wood, promoting a circular practice that minimizes wood waste and reduces landfill usage, transportation needs, and carbon emissions. Additionally, the wood retains the carbon absorbed by trees during their growth, storing it in the floors and walls of buildings. As infrastructure demands increase, sustainable wood offers an environmentally friendly solution to meet these needs.

Why the Construction Industry Needs Sustainable Wood

Sustainable wood, particularly through the use of mass timber, is gaining recognition as a critical climate solution in the construction industry. Traditional building materials like concrete and steel are carbon-intensive to produce, responsible for nearly 8% of global carbon emissions. In contrast, mass timber is derived from a renewable resource: trees. Through responsible forest management, trees can be harvested and replanted in a sustainable cycle, allowing forests to continue absorbing carbon dioxide. The wood used in mass timber stores this carbon long after the trees are cut down, effectively sequestering it in the walls, floors, and structures of buildings for decades or even centuries. This makes sustainable wood not only a viable building material but also a carbon sink, helping reduce the overall carbon footprint of new construction.

The production of mass timber involves using smaller, fast-growing trees that are often thinned from forests to maintain ecological health. These pieces of wood are dried and glued in layers, forming large, strong panels that can be used for walls, floors, and even entire building frames. This technique reduces waste by making use of smaller trees or leftover wood that might otherwise be discarded. Additionally, mass timber is much lighter than steel and concrete, reducing the energy needed for transportation and lowering emissions from construction sites. The process can also incorporate repurposed or recycled wood in a closed-loop system, further contributing to the circular economy and minimizing waste.

The climate benefits of sustainable wood go beyond carbon storage. Timber construction has a much lower embodied carbon than steel and concrete, which require energy-intensive processes to extract and manufacture. By substituting these materials with mass timber, builders can reduce carbon emissions by up to 70%. In regions where sustainable forestry practices are employed, this approach also supports local ecosystems by preventing deforestation, protecting biodiversity, and encouraging the regeneration of forests. Importantly, mass timber’s design allows for prefabrication, which reduces construction time and waste, making it not only a greener option but also an economically competitive one.

As cities and communities around the world grapple with the need for affordable housing while also addressing climate change, sustainable wood provides a promising solution. By scaling up the use of mass timber in mid- and high-rise buildings, the construction sector can reduce its reliance on carbon-heavy materials, sequester large amounts of carbon, and promote sustainable forest management practices. This integration of environmental, economic, and social benefits positions sustainable wood as a key player in the transition toward a low-carbon future.

The Future of Sustainable Wood: Making Construction Faster and Greener 

Sustainable wood, especially when derived through the use of mass timber, offers a range of environmental, economic, and structural advantages over traditional building materials. From a structural standpoint, mass timber is both strong and lightweight, making it a highly versatile material. It has a high strength-to-weight ratio, allowing it to be used in large, multi-story buildings while reducing the overall load on foundations and minimizing transportation costs. Additionally, mass timber is more fire-resistant than many people realize; when exposed to fire, the outer layer of the wood chars and insulates the inner core, slowing down the spread of fire and maintaining the building’s integrity for longer than some steel structures. This combination of strength, fire resistance, and flexibility gives mass timber a competitive edge in construction.

Economically, sustainable wood offers cost-saving opportunities through faster construction times and less material waste. Mass timber panels can be prefabricated off-site, reducing the time spent on construction and the labor costs associated with traditional methods. This efficiency not only lowers the overall cost of building but also minimizes disruption in urban areas. Furthermore, the use of repurposed or recycled wood supports a circular economy, where resources are reused rather than discarded, reducing the environmental impact and fostering a more sustainable construction industry. As demand for sustainable and affordable housing rises, mass timber presents a compelling, eco-friendly alternative to conventional building practices.

One of the most significant benefits is its ability to sequester carbon. Trees naturally absorb carbon dioxide from the atmosphere as they grow, and this carbon remains stored in the wood even after it’s used in construction. By utilizing wood in buildings, the carbon is locked away for the lifespan of the structure, helping to reduce overall greenhouse gas emissions. In contrast, materials like concrete and steel release large amounts of carbon during their production, contributing to climate change. This makes mass timber a powerful tool in the fight against global warming, especially when paired with sustainable forestry practices.

Sustainable Wood Skepticism

Despite its many advantages, the use of sustainable wood and mass timber as a building material does have some drawbacks and criticisms. One primary concern is the reliance on sustainable forestry practices. If forests are not properly managed, large-scale timber harvesting can lead to deforestation, habitat destruction, and biodiversity loss. The success of mass timber as a climate solution depends on responsible sourcing, including replanting trees to maintain the carbon-absorbing benefits of forests. Unsustainable logging practices or overharvesting could negate the environmental benefits of mass timber by releasing more carbon into the atmosphere and harming ecosystems.

Another challenge is the perception of wood’s durability and fire safety. While mass timber is engineered to be fire-resistant, some critics remain concerned about its performance in large-scale buildings. Public perception and regulatory hurdles can be barriers to adoption, as many building codes and fire safety standards are based on traditional materials like concrete and steel. These regulations may need to be updated to reflect the true performance of mass timber, but in the meantime, they can slow down its widespread use in urban construction.

Additionally, there are economic concerns, particularly regarding initial costs. While mass timber can reduce construction time and labor costs, the price of sustainably sourced wood can be higher than that of conventional materials, especially if demand outstrips supply. The infrastructure for large-scale mass timber production is still developing, and until it reaches full maturity, the material may remain more expensive and less accessible than concrete or steel, limiting its adoption in some markets. Over time, these challenges may be addressed, but they highlight the need for careful planning, regulation, and investment in the mass timber industry.

As climate change accelerates, climate risks are beginning to impact every aspect of society from infrastructure and transportation to health, biodiversity, and air and water quality. A climate risk is the potential for climate change to have adverse consequences for a human or ecological system. Climate risks have implications for property and infrastructure, posing a threat to the global financial system at large. 

The rate at which climate change and its associated risks are increasing can be reduced through mitigation and adaptation actions such as investing in green infrastructure and implementing energy efficiency standards. The assessment of climate risk involves the identification and quantification of the potential impacts of climate change on an organization, region, or community. Many organizations utilize climate risk assessments, which involve evaluating current and future vulnerabilities to climate-related hazards, taking into account factors such as infrastructure resilience, economic stability, and social vulnerability. To quantify those impacts, assessments typically estimate the level of damage in financial terms. In order to streamline this process and make it easier for companies to identify their potential risk, riskthinking.AI has developed a platform to leverage climate change risks and impacts through AI software.

Integrating AI technology into climate risk assessments

Riskthinking.Ai integrates AI technology with climate change data to evaluate financial risk management through their development of the ClimateEarthDigitalTwin (CDT). The CDT integrates physical asset data with the latest climate projections like extreme weather and temperature shifts. Rather than using deterministic forecasts, CDT relies on probabilistic distributions to simulate a range of future scenarios and project changes in an asset's value over time. The CDT platform quantifies exposure and impacts from climate change. Riskthinking.Ai identifies which specific risk factors, such as extreme heat and floods, contribute to overall exposure. This approach can guide decision-making and help assess the complex risks posed by climate change and inform future infrastructure investments, risk mitigation, and climate adaptation strategies.

Upsides to AI assessment 

Riskthinking.Ai enables organizations to evaluate future financial impacts of climate change, integrating climate risks into business decisions. Countries especially vulnerable to climate change may benefit from this algorithm, as it allows for a better understanding of the threats they face due to a changing climate. By providing countries, governments, and corporations with a better understanding of how they may be at risk due to their geographical location and respective climate vulnerability, AI technology can guide decision-making to inform proper adaptation and mitigation into the future. 

Downsides to AI assessment 

Although Riskthinking.Ai provides a tangible strategy in informing proper adaptation and mitigation, many argue that the use of AI technology to address environmental crises is counterintuitive due to AI’s negative impacts on the environment. By 2040, it is predicted that the emissions from the Information and Communications Technology (ICT) industry will amount to 14% of global emissions, with the majority being driven through ICT infrastructure, specifically data centers and communication networks which AI relies upon to operate. In addition to the significant energy consumption required to power AI technology, a large amount of water is needed for cooling data centers. Further, AI relies on critical minerals and rare elements which are mined for unsustainability and the rapidly increasing data centers contribute to the growing body of electronic waste. However, as AI becomes increasingly applied to environmental problems, it can prove to be a valuable tool in combating climate change. Thus, working to reduce the environmental impact of AI technology will not only be vital in its application for climate risk assessments, but in mitigating the harmful effects brought about by its rapidly increasing societal demand.

Nature is Nonpartisan is a bipartisan, solutions-focused coalition working to unite Americans around shared environmental goals. By fostering cross-party support for conservation and land stewardship, the organization hopes to reframe climate action as a unifying national priority rather than a partisan fight. 

Establishing Nature as Middle Ground

In recent years, environmental politics in the U.S. have been paralyzed by partisan gridlock, stalling climate progress. Nature is Nonpartisan aims to break this deadlock by reframing environmentalism around common-sense values, such as safety, access to the outdoors, and community well-being. By engaging Americans across the political spectrum, the coalition seeks to depoliticize climate solutions and ground them in conservation principles that resonate more universally: protecting public lands, supporting disaster-affected communities, and ensuring access to clean air and water.

This approach gained national attention in early 2025 when founder and CFO Benji Backer, alongside coalition members, briefed White House staff on nonpartisan conservation strategies. A meeting scheduled for fifteen minutes extended well over an hour, ultimately influencing President Trump’s unexpected June 2025 signing of the “Make America Beautiful Again” executive order. The order focuses on conserving public lands, safeguarding wildlife, and securing clean drinking water. Backer underscored that wildfires, drought, and ecosystem collapse don’t just affect the environment; they threaten billions in outdoor-recreation revenue and undermine the hunting, fishing, and farming traditions valued across political lines.

Nature is Nonpartisan’s narrative emphasizes that environmental protection is not only about climate, but also the American landscape, economic security, and the natural heritage millions rely on and cherish.

Conservation as Climate Action

Nature is Nonpartisan’s work centers on four key conservation areas: managing forests to reduce wildfire risk, enhancing water quality and improving water infrastructure, enhancing natural disaster resilience, and promoting responsible land stewardship. Together, these priorities offer a practical, bipartisan path to protect ecosystems and communities most vulnerable to climate change.

Overall, emphasizing conservation provides a widely palatable, bipartisan entry point into climate action. By restoring ecosystems, sequestering carbon, and protecting biodiversity, these efforts simultaneously strengthen local economies — particularly in rural regions dependent on recreation and natural-resource industries — while building long-term climate resilience. 

The Tension Beneath the Surface

Despite its promise, Nature is Nonpartisan’s work exists within a fraught political landscape. Environmentalism and conservatism are still often framed as ideologically incompatible, a perception the organization works actively to undo. While the “Make America Beautiful Again” executive order signals progress, critics argue it may be more symbolic than substantive, especially given President Trump’s longstanding dismissal of climate science. Some fear the order could serve more as a political performance than a genuine environmental advancement.

These tensions point to the broader challenge: decades of conservative skepticism toward climate science have made it difficult to ensure follow-through on policy. Nature is Nonpartisan hopes to continue confronting this distrust by reframing environmental protection around nationally shared values — family, future generations, clean water, clean air, and access to the outdoors — whether one is a Midwestern farmworker or a city resident.

The Power of Words and Bipartisan Policy

Communications Director Amelia Joy emphasizes that language is crucial to keeping these efforts genuinely nonpartisan. Because the word “climate” has become politically charged, Nature is Nonpartisan often avoids leading with it. Instead, Joy notes that many of the organization’s core priorities, from wildfire prevention to natural disaster resilience, are climate issues, but by centering them in everyday terms, the coalition can build durable, cross-party support that can outlast any single administration.

Policy Director Maya Cohn adds that progress doesn’t have to depend on who is in office. She emphasizes that policy advances can happen under any president or Congress if people are willing to work across political lines. For her, bridging divides and having honest conversations, even with those you disagree with, is the only way to create long-lasting environmental solutions.

The Waverley Street Foundation, founded by Laurene Powell Jobs in 2016, aims to attack climate related issues through funding community-led programs, leading to community action against climate change. The Waverley Street Foundation specifically funds programs related to renewable energy and regenerative agriculture, as these sectors have an immense impact on the environment and vulnerable communities. The Foundation’s approach to achieving climate-related goals is unique, as their solutions revolve around investing in prominent community institutions in order to benefit the entire community, showing people that we all benefit from a healthy planet.

Regenerative Agriculture as a Climate Solution

Regenerative agriculture is the practice of using farming and agricultural techniques to help reverse climate change, including some techniques that date back to Native American cropping systems and the way in which they interact with the soil. According to the California Department of Food and Agriculture, the goals of the practice include helping to “mitigate climate change, improve soil health, restore biodiversity, enhance ecosystems, and contribute to human health.” By focusing on the larger community impacts of sustainable farming practices, the Waverley Street Foundation promotes a close connection between people and their food systems. As an example,  the Foundation established agreements with local school districts to support fresh and nutritious lunches, bringing  local regenerative farmers into the supply chain, thereby improving farmers’ economics, and allowing them to decide to continue planting regenerative crops. 

Other Community-Based Climate Initiatives

The Waverley Street Foundation is also currently working on converting health clinics from being run on diesel fuel to solar in India. This not only reduces pollution and carbon emissions, but can also help make healthcare more affordable for residents, while providing new local jobs installing, fixing, and financing the panels. In order to evade the most devastating climate change impacts, emissions need to be reduced by almost half by 2030 and reach net-zero by 2050. 

The ultimate goal of the Waverley Street Foundation is to approach climate change with a new outlook: “Cultivating Health, Justice and Joy,”  emphasizing the role that climate change has in harming vulnerable communities’ everyday lives rather than solely focusing on technical solutions. Jared Blumenfeld, the president of the Waverley Street Foundation, argues that “unless we can make the case to them, that climate action is going to support and make their communities stronger, I don't think we win many of the other arguments.”

About Our Guest

Jared Blumenfeld is the former Secretary of CalEPA and current President of Waverley Street Foundation, the climate philanthropy funded by Laurene Powell Jobs. Blumenfeld also served as Director of San Francisco’s Department of Environment. Currently, at Waverley, he is working on critical environmental issues, such as oil litigation, renewable energy, regenerative agriculture, and food systems.

Single-use plastics are extremely harmful to the environment, both in terms of their production and disposal. All plastic creates issues regarding fossil fuel emissions and waste, but single-use plastics are specifically detrimental because they contribute to the immense amounts of waste piling up on our planet. Because these plastics are not biodegradable, according to EarthDay, “79% of plastic that has ever been made still sits in landfills or the natural environment.” 

While numerous efforts have been made to reduce the amount of single use plastics available, the amount of plastic entering our landfills has yet to substantially decrease. For example, in 2014, California enacted a ban on thin plastic shopping bags at supermarkets and other stores, but allowed customers to purchase bags made with thicker plastics, which retailers argued would make them recyclable and reusable. In reality, consumers were not reusing or recycling the thicker plastic, ultimately leading to an increase in the poundage of plastic trashed per person. 

Reusable Bags as a Climate Solution

Lotus Sustainables aims to eliminate single-use plastic by providing eco-friendly alternatives, with reusable grocery bags and food storage pouches. Founded by Jennifer and Farzan Dehmoubed in 2017, the company aims to eliminate the need for single use plastic. Since its founding, they have been able to divert 5 billion bags from landfills. Lotus also prioritizes ethical and sustainable manufacturing efforts by closely monitoring the production and studying the life cycle of their products. The bags are made with eco-friendly materials such as recycled plastic bottles for fabric and renewable resource products like jute, a plant based fiber. Using these materials ensures that the product is durable and reusable. The process reduces the amount of waste that enters landfills both by using recycled products, and creating a long-term, reusable alternative.

Lotus’ mission also contains environmental justice initiatives. In pursuit of these goals, Lotus donates 10% of their profits to likeminded companies, including The Plastic Pollution Coalition, the Surfrider Foundation, and Project New Village. Further, according to co-founder Jennifer Dehmoubed, the company donates to “Black-created organizations that focus on food justice, the preservation of land, and enriching agriculture,” with hopes to “repair horrific injustices imprinted in the Earth and bring ownership of the land and agriculture education into the hands and lives of Black people.”

Challenges of Implementation

In order to realize Lotus’ goals, consumer demand and legislation must respond to the planet’s growing need to eliminate single-use plastic. Without the support of consumers, no amount of legislation or innovation can have an impact. According to Jesse Langley, CEO of Lotus Sustainables, “ Legislation doesn't happen unless there's people behind it…And same thing with businesses, these businesses are not gonna get behind an initiative if Consumers are not looking for it.”

Pumped storage hydropower, also known as water batteries, are often used as a means to store excess renewable energy. For example, solar and wind may generate more energy than is needed during certain times of the day and less than what is needed at other times.  As a result, water batteries are extremely useful as a way to store and release energy during peak demand periods or when renewable sources are unavailable (i.e, when the sun is down). This form of energy storage is used in many places across the country, and across the world, including Tennessee, Kentucky, and San Diego. 

Current and Future Use of Pumped Storage Hydropower

In San Diego County, a proposed pumped storage hydropower project would connect a lake to large underground pipes which will “connect this lake to a new reservoir… 1100 feet higher in elevation” so that “when the sun is high in the sky, California’s abundant solar power will pump water into that upper reservoir.” When the sun is down, the water would be released to the lower lake, generating around ”500 megawatts of electricity for up to eight hours” which is “enough to power 130,000 typical homes.”

At Tennessee’s Raccoon Mountain, TVA stores the excess energy as gravitational potential energy and produces about “1700 megawatts of electricity” when in demand during the day. It takes extremely long for these projects to get approved because the investment is “more than 2 billion dollars for a large plant”.  The project consists of three components: a lower reservoir “bounded by a 62 meter high dam” and “replenished as need to make up for evaporation;” an underground powerhouse which is “a 137-meter-long cavern” housing “three pump turbines;” and an upper reservoir which “would be some 600 meters across and bounded by a 53 meter high dam.”

All currently operating pumped storage hydropower projects in the U.S. are “open-loop” facilities, meaning the lower reservoir is a natural water source such as a lake or river. This is the case with the San Diego and Racoon Mountain projects. In contrast, “closed-loop” pumped storage is built offstream and operates independently of natural waterways. For example, at a proposed pumped storage facility in Kentucky, an old coal mine is being repurposed to be used as a water battery. This land has “hosted mining for at least 70 years” and this “project would deliver up to 287 megawatts of power for up to 8 hours, giving it more storage in the tank than the biggest lithium battery plants built thus far”. Closed-loop pumped storage is generally viewed more favorably than open-loop systems by many environmental groups, tribes, and modern hydropower developers because it avoids continuous interaction with natural waterways and can reduce impacts on fish and river ecosystems.

Benefits of Water Batteries

Water batteries are incredibly useful for long-duration energy storage and can help balance fluctuations in renewable energy sources like solar and wind by providing power during peak demand periods. For instance, in San Diego, “the San Vincente project would store roughly as much electricity as batteries in 50,000 of Tesla’s long range Model 3 cars” and does not need materials like cobalt and lithium which are not only hard to find but create a lot of e-waste (and side effects with mining). Moreover, these projects fuel the economy and can create an abundance of construction jobs.

Challenges of Implementation

Pumped hydropower requires a lot of land, and flooding impacts habitat, and in some cases areas protected by indigenous tribes. The land and local ecosystem impacts can be very substantial. Moreover, water batteries require significant elevation difference between reservoirs to be effective so there are often geographic limitations to deployment. It can be extremely challenging to find places to build water batteries because they require specific topography as well as impacting the surrounding landscape. On top of this, these “facilities are expensive to build and take years to develop”. However, once they are in full structural integrity, they “store energy for far longer than lithium-ion batteries… and they last for many decades with minimal deterioration.”

Erik Steimle emphasizes that pumped hydropower/water batteries are a great way to generate energy in a more sustainable manner, however, he acknowledges that there are some downfalls of it. For example, pumped hydropower/water batteries must undergo extensive regulatory practices involving federal agencies that other types of energy storage and renewables do not, posing a barrier to widespread accessibility. Another benefit is the durability of this equipment, which can be useful for hundreds of years.

Can we talk to animals, or at least understand what they are saying to each other?  That’s a question that researchers hope to answer with the help of AI. Earth Species Project, a non-profit that develops sophisticated AI technologies, hopes its software can help. Specifically, they have developed Nature-LM audio which is an audio-language machine learning algorithm with the potential to decipher animal communications.

How does it work?

By gathering and evaluating huge amounts of audio information from different species, Nature-LM audio can identify  “individuals in recordings”, and evaluate patterns.  For software users, it does not require the user to have any programming skills. Specifically “analyzing animal sounds… [allows for] decoding complex communication and behaviors to monitor the health of entire ecosystems.”

This AI model was trained on “bioacoustic archives like Xeno-canto, iNaturalist, the Watkins Marine Mammal Sound Database, and the Animal Sound Archive” along with “general audio, human speech, and music data” while connecting this ”audio encoder to a leading language model.”

Benefits of this approach

NatureLM “can classify or detect thousands of species across diverse taxa including birds, whales, and aurans–without the need to retrain the model for each task.”. It has other capabilities like “predicting life-stage and simple call-types of birds, and captioning bioacoustic audio” which are useful when trying to analyze the behavior of different species and their associated cues. The software enables evaluation of large amounts of animal sounds and allows evaluation of that data “freely via human language text”.

According to a benchmark that they established, called the Beans-zero, which “provides a standardized way to measure… performance across various bioacoustic tasks, enabling consistent comparisons and fostering progress in the field”, NatureLM-audio “achieves state-of-the-art performance on most tasks”. This is especially true in regards to bird and marine mammal sounds, which they are able to identify without fine-tuning–an extremely gruesome task in machine learning to change pre-existing models which better fit your data and train it for specific tasks.

Potential Drawbacks

Like all AI models, Nature LM-audio could impact employment opportunities, in this case for  animal biologists and researchers, and by using substantial amounts of energy to run the model.  And, like all AI programs, any conclusions and decisions made through the program need to be carefully evaluated.  It will take time and effort to determine how valuable the model is.   

Conclusion

Raskin believes that the creation of NatureLM has many positive implications because it allows humans to listen to the voices of animals. It gives us an understanding of their behavior to not only learn more about them, but also by giving insights on how to help them with conservation efforts. Moreover, it can alert researchers to what exactly is endangering certain species, prevent these efforts, and create a lot of more data necessary to analyze trends.

What is COF 999?

UC Berkeley chemistry professor Dr. Omar Yaghi recently led a study which has the potential to be revolutionary in reducing the quantity of carbon dioxide present in the atmosphere. “Covalent organic framework number 999,” or COF 999, is a yellow, powder-like material that has billions of tiny holes. Inside of these holes, researchers in Dr. Yaghi’s lab have installed molecular units that can seek out carbon dioxide, enabling the substance to suck in and capture the carbon dioxide. COF 999 has a huge capacity for absorbing emissions; half a pound of the powder can absorb as much carbon dioxide as a tree captures in a year.

The carbon dioxide problem

The quantity of carbon dioxide in the atmosphere has reached an all-time high, with a global average in 2023 of 419.3 parts per million. This immense amount of carbon dioxide in the atmosphere comes from a number of human sources, the most common of which is the burning of fossil fuels such as coal, oil, and natural gas for energy. Carbon dioxide is the most abundant greenhouse gas in the atmosphere, and contributes significantly to global warming and other environmental issues, including ocean acidification.

Applying COF 999 

In an interview with Forbes, Dr. Yaghi described the way he sees COF 999 being implemented as a solution. The powder can be made into pellets or a coating, and then integrated into facilities where flue gas –the gas that is released from industrial processes –is released. “This flue gas would pass through the material and because it just plucks out CO2, it cleans CO2 from that flue before it reaches the atmosphere.” According to the San Francisco Standard, Dr. Yaghi says that the powder “requires no energy, shows no signs of degradation even after 100 uses, and is made from inexpensive, commercially available materials.”  Another benefit is that the material only needs to be heated to 50 or 60 degrees Celsius, rather than to 120 like many other traditional materials necessary for carbon capture.

In order to see significant change in the atmosphere’s carbon dioxide concentration, we will need to couple preventing carbon dioxide emissions with direct air capture, which COF 999 can also do. According to Zihui Zhou, a UC Berkeley graduate student who worked in Dr. Yaghi’s lab says, “Currently, the CO2 concentration in the atmosphere is more than 420 ppm, but that will increase to maybe 500 or 550 before we fully develop and employ flue gas capture. So if we want to decrease the concentration and go back to maybe 400 or 300 ppm, we have to use direct air capture.” It will take time, however, for scientists to be able to use COF 999 effectively. This is because the powder has not been tested in real-life scenarios, and therefore the costs and risks from the powder are largely unknown; for example, the powder might restrict air flow through filters when applied, reducing the practicality of the powder.

As ocean temperatures increase due to climate change, an emergent crisis known as coral bleaching is on the rise. Coral bleaching poses the largest threat to coral reefs, which are some of the most diverse ecosystems in the world. Coral reef habitats occupy less than one percent of the ocean floor, but constitute more than 25% of all marine life, providing habitats for a vast array of species from small organisms to large fish and sharks. Additionally, biodiverse reefs provide a variety of economic benefits, supporting jobs, tourism, and fisheries. Reefs also protect lives and property in coastal areas, absorbing 97% of a wave’s energy while buffering against currents, waves, and storms.

However, when ocean temperatures rise, corals become stressed and expel the marine algae living inside their tissues, known as zooxanthellae. Typically, coral live synergistically with zooxanthellae, meaning the algae provide food for the coral while the algae use the coral as shelter. Due to stress, corals expel zooxanthellae, causing them to become a white skeleton. If the temperatures remain high, the coral won’t allow the algae back and the coral will die. Once corals die, reefs rarely come back. As climate change progresses with its warming trend, corals endure greater stress, and experience longer and more intense bleaching events. Between 2014 and 2017, 30% of the world’s reefs experienced heat-stress leading to coral bleaching. In 2005, the US lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event. Fortunately, marine biologists have been working on a new strategy to restore damaged coral reefs, known as Coral IVF (in vitro fertilization), which entails taking healthy coral eggs and sperm, crossing them in a supervised pool, and returning the mature coral to a damaged coral reef. Importantly, IVF coral are often bred to be resilient to heat-induced bleaching, making Coral IVF a successful strategy in fortifying reefs against bleaching.

What exactly is Coral IVF?

Coral IVF begins with biologists collecting spawn, or coral eggs and sperm, from heat-tolerant corals that have survived coral bleaching events. With these spawn, biologists can rear millions of baby corals in tanks and coral nursery pools before repopulating damaged reefs for restoration. So far, coral IVF has proven successful. The Great Barrier Reef (GBR) Foundation planted 22 large colonies of new baby corals off Heron Island in 2016. Four years later, the researchers found that the corals had survived a bleaching event and grown to maturity. The next year, the corals had reproduced and spawned babies of their own. 

In 2016, 81% of the northernmost section of the GBR was severely bleached, including mass bleaching in other sections. The GBR provides an estimated economic value of $56 billion, including 64,000 jobs stemming from the reef. Losing the reef would be a major economic loss for Australia, which has already lost 50% of its coral since 1995. With coral IVF, there is hope for an eventual repopulation of the reef with healthy corals. Beyond the GBR, coral IVF is taking place in reefs across the US, Mexico, and the Caribbean. Approximately 90% of IVF-created corals survived 2023’s heat wave, holding on to the algae that sustain them.

The Advantages of Coral Breeding

Coral IVF not only mitigates short term reef loss, but also strengthens reefs in the long term. One study revealed that corals in the GBR that survived bleaching in 2016 had twice the average heat tolerance the following year. Research reveals that corals can pass on their adaptive strategies to their offspring. Experiments also reveal that heat-adapted corals can thrive in new environments and be an important source of reef regeneration globally. This technique can therefore be applied to any coral population. Further, the IVF process also can be done quickly, allowing scientists to respond to coral damage in an emergency.

Climate change poses an insurmountable risk

Unfortunately, climate change still poses a threat to IVF created coral reefs. By 2049, annual bleaching events will become the norm in the tropics. Research reveals that as global temperatures rise, coral will become less tolerant to heat related stress. In Australia, there has been a massive bleaching event every other year for six years. Due to the frequency of such events, coral's ability to reproduce is compromised for a number of years. As global emissions continue to rise, temperatures will continue to rise, inducing further heat-related stress. Eventually, coral may not be able to live in excessively hot ocean waters. Coral IVF is an effective strategy to prepare corals for future temperatures, but likely only up to a certain point.

Through the rise in pop culture, climate change awareness has increasingly been integrated into the entertainment industry. Particularly in the Black community, multimedia cultural campaigns are used to increase interest in environmental movements with the use of light-hearted, fun content. Artists, musicians, and influencers are leveraging their platforms to highlight the impacts of climate change and promote sustainable practices, which, in turn, provides easily accessible resources and information to marginalized communities that empower them to participate in the fight against climate change. 

Black Communities and Environmental Justice

Populations of color face disproportionate energy burdens caused by climate change. A study conducted by Rice University found that Black communities were more prone to live in vulnerable areas, a generational problem caused by the history of Black gentrification. Even now in 2024, Black communities in Georgia are forced to pay higher electricity bills, despite having lower rates compared to other states, due to old and inefficient household systems. According to the National Black Environmental Justice Networks, African Americans were also found to breathe in 56% more pollution than they cause, whereas their White counterparts breathe in 17% less pollution than generated. African Americans are also 75% more likely than White Americans to live in polluted communities, leading to 13.4% of African American children suffering from asthma, compared to 7.3% of White children. 

Starting in the 1970s, some black musicians included environmental themes in their productions. Artist Marvin Gaye released “Mercy Mercy Me (The Ecology)” to tackle discussions about oil spills and mercury waste; funk group Earth, Wind, & Fire released “Burnin’ Bush” to bring awareness about the global destruction of Mother Earth. Those themes continue today in  music produced by Black artists, such as in the popular single “Feels Like Summer” by Childish Gambino, which conveys worries about uncertain impacts caused by global warming. Additionally, artists such as SZA have partnered with brands to promote sustainable merchandise, encouraging a societal paradigm to rely on eco-friendly products. 

Representation and Education

With more than 50% of the world’s population active on social media, people are continuously exposed to the influx of information circulated by entertainment. Through the entertainment industry, climate news has become increasingly accessible and engaging, allowing communities to educate themselves on sustainability and mobilize action. Although hip-hop and rap were once considered controversial music genres due to themes of violence, drugs, and misogyny, there is a growing effort to utilize the storytelling aptitude of these genres for social and environmental commentary. Artists use rhymes and flow in hip-hop and rap to effectively share the living conditions, natural disasters, and climate injustice that people face. This empowerment of entertainment has motivated marginalized people to strengthen their community bonds and collaborate in fighting against climate change. The widespread influence of entertainment is fostering inspiration for a new culture promoting climate equity and agency, as well as the normalization of environmentalism in society.

Historically, India has faced challenges with persistent air pollution as a result of industrial development. One key approach to combat this has been to reduce greenhouse gas emissions. For example, Indian policymakers have been pushing for the commercialization of electric vehicles which has unlocked various incentives for companies like Vision Mechatronics to develop electric vehicles run by lithium-ion batteries. 

How Lithium-Ion Batteries Power EVs

India “seeks to attain a 30% share of electric vehicles, in the total vehicles sold, by 2030” and accelerating the market for it by “moving from incentives to mandates” like a Zero Emission Vehicle policy (NITI Aayog). Taking advantage of this political support, Vision Mechatronics “aims to develop a complete domestic ecosystem around EVs” which have “zero tailpipe emissions” (Vision Mechatronics). 

Many electric vehicles are driven by lithium ion batteries which “can contain hundreds of individual cylindrical battery cells that are the same shape as common AA and AAA batteries” (Edmunds). They are extremely energy efficient and can store a multitude of energy; on full battery, electric cars powered by lithium-ion batteries can drive over 200 miles–although it may depend on the specific car model. Compared to their precursor, lead-acid batteries, lithium-ion batteries have higher energy density which increases the mileage of a car. They are also extremely lightweight and this ensures that EVs aren’t too heavy. Moreover, the electricity used to refuel the EVs come from renewable energy sources like solar power. 

The Environmental Cost of Battery Production

There are various concerns that lithium-ion battery powered cars take a long time to charge. Although this may be true for some models, recent developments have led to an increase in charging efficiency and overall energy storage. For instance, the Hyundai Ioniq 5 can be charged “from 10% to 80% in just 18 minutes” (Edmunds).

Moreover, the environmental impact that the creation of lithium-ion batteries has is detrimental as “the mining process for lithium and other materials used in these batteries can… lead to water pollution and habitat destruction” (Tara Electronics). Although this is the undeniable truth, it is promising to know that due to advancements in technology it has been shown that electric car batteries can “last 12 to 15 years in moderate climates”, meaning that they don’t have short lifespans (Edmunds). Moreover, “instead of ending up in a scrapyard like most internal combustion engines do, electric vehicle batteries can be repurposed, refurbished, or recycled when they fail” (Edmunds).

Building India's EV Ecosystem

Gupta believes that local battery production in India can help India progress towards an economy that is powered by clean energy. She mentions that it has been difficult to employ skilled labor in this field due to geopolitical tensions and a lack of awareness regarding the importance of this field. However, she is trying to bridge this gap by making opportunities in her company as accessible to the next generation as possible.

In Indiana, evangelical churches are finding new ways to live out their faith through environmental action. With support from the Evangelical Environmental Network (EEN), congregations are installing solar panels, planting native gardens, creating nature play areas for preschoolers, and even adding electric vehicle charging stations. This initiative, often referred to by Christians as “creation care,” positions environmental stewardship and climate action as a biblical responsibility.

What is the Evangelical Environmental Network?

EEN is a biblically-based ministry and the environmental arm of the National Association of Evangelicals, dedicated to mobilizing Christians around climate action. By collaborating with churches, universities, and seminaries, the organization offers education on how creation care is a collective mission among evangelicals. In Central Indiana, this has meant congregations and Christian universities working together on eco-friendly infrastructure and community events such as Indy Creation Fest, an Earth Day-like celebration that joyfully highlights humanity’s duty to conserve and steward the beauty God bestowed on us.

Creation Care as Protecting the Poor

A central theme of EEN’s work is showing Christians that defending the poor and vulnerable also means addressing pollution — including from plastic, methane, and mercury — and climate change. Low-income communities often face the harshest impacts of extreme climate disasters, poor air quality, and contaminated water. By making this connection clear, EEN reframes environmentalism as an act of justice and compassion for humanity, aligning climate action with evangelical priorities. Their programs highlight not only environmental threats but also human health risks, from asthma linked to air pollution to the dangers of unsafe drinking water.

The Building of a Movement

Creation care is still a growing movement and remains a minority position within American evangelicalism. Some believers continue to prioritize human welfare over environmental stewardship without recognizing that the two are inseparable. Historically, evangelicals have been among the groups least likely to regard climate change as urgent and express wariness about climate science. While the visible progress in Indiana is promising, it remains only a small step in the broader effort to normalize creation care across the evangelical community. 

Nonetheless, by centering their approach on shared religious values, EEN helps evangelical Christians see climate action not as a burden, but as a natural extension of their mission to honor God and all of creation.

About Our Guest

Rev. Dr. Jeremy Summers, the Director of Church and Community Engagement at EEN, emphasizes that caring for the environment and caring for people are one in the same. He works with churches, universities, and local communities to connect biblical principles with climate action, advancing the creation care movement within evangelical circles. Within these spaces, he urges Christians to understand that protecting ecosystems is necessary to protect the people who live in them, especially those from marginalized groups who suffer most from pollution, climate change, and environmental injustice.

As climate change accelerates, climate risks are beginning to impact every aspect of society from infrastructure and transportation to health, biodiversity, and air and water quality. A climate risk is the potential for climate change to have adverse consequences for a human or ecological system. Climate risks have implications for property and infrastructure, posing a threat to the global financial system at large. 

The rate at which climate change and its associated risks are increasing can be reduced through mitigation and adaptation actions such as investing in green infrastructure and implementing energy efficiency standards. The assessment of climate risk involves the identification and quantification of the potential impacts of climate change on an organization, region, or community. Many organizations utilize climate risk assessments, which involve evaluating current and future vulnerabilities to climate-related hazards, taking into account factors such as infrastructure resilience, economic stability, and social vulnerability. To quantify those impacts, assessments typically estimate the level of damage in financial terms. In order to streamline this process and make it easier for companies to identify their potential risk, riskthinking.AI has developed a platform to leverage climate change risks and impacts through AI software.

Integrating AI technology into climate risk assessments

Riskthinking.Ai integrates AI technology with climate change data to evaluate financial risk management through their development of the ClimateEarthDigitalTwin (CDT). The CDT integrates physical asset data with the latest climate projections like extreme weather and temperature shifts. Rather than using deterministic forecasts, CDT relies on probabilistic distributions to simulate a range of future scenarios and project changes in an asset's value over time. The CDT platform quantifies exposure and impacts from climate change. Riskthinking.Ai identifies which specific risk factors, such as extreme heat and floods, contribute to overall exposure. This approach can guide decision-making and help assess the complex risks posed by climate change and inform future infrastructure investments, risk mitigation, and climate adaptation strategies.

Upsides to AI assessment 

Riskthinking.Ai enables organizations to evaluate future financial impacts of climate change, integrating climate risks into business decisions. Countries especially vulnerable to climate change may benefit from this algorithm, as it allows for a better understanding of the threats they face due to a changing climate. By providing countries, governments, and corporations with a better understanding of how they may be at risk due to their geographical location and respective climate vulnerability, AI technology can guide decision-making to inform proper adaptation and mitigation into the future. 

Downsides to AI assessment 

Although Riskthinking.Ai provides a tangible strategy in informing proper adaptation and mitigation, many argue that the use of AI technology to address environmental crises is counterintuitive due to AI’s negative impacts on the environment. By 2040, it is predicted that the emissions from the Information and Communications Technology (ICT) industry will amount to 14% of global emissions, with the majority being driven through ICT infrastructure, specifically data centers and communication networks which AI relies upon to operate. In addition to the significant energy consumption required to power AI technology, a large amount of water is needed for cooling data centers. Further, AI relies on critical minerals and rare elements which are mined for unsustainability and the rapidly increasing data centers contribute to the growing body of electronic waste. However, as AI becomes increasingly applied to environmental problems, it can prove to be a valuable tool in combating climate change. Thus, working to reduce the environmental impact of AI technology will not only be vital in its application for climate risk assessments, but in mitigating the harmful effects brought about by its rapidly increasing societal demand.

Climate education has the potential to drive the public towards climate science literacy, an individual’s understanding of their influence on climate and climate’s influence on them and society. According to the National Oceanic and Atmospheric Administration, a climate-literate person: 

• understands the essential principles of Earth’s climate system,
• knows how to assess scientifically credible information about climate,
• communicates about climate and climate change in a meaningful way, and
• is able to make informed and responsible decisions with regard to actions that may affect climate.

Climate change education is more than just science education; it is an interdisciplinary topic that involves understanding the relationship between climate change, history, economics, social studies, and more. A robust and interdisciplinary climate education provides an understanding of the large-scale social transformation necessary to increase climate resiliency and implement effective solutions.

Empowering Future Solution Makers 

Climate education can provide younger generations with the knowledge, skills, attitudes, and values that are necessary to make more environmentally informed decisions. By equipping students with a thorough understanding of climate science and illuminating the scientific process utilized by climate scientists, students become armed to critically assess climate discourse and solutions. Moreover, climate education fosters a sense of agency: youth may grow up to vote for climate positive policies, pursue careers that strive towards climate solutions, have a more eco-conscious lifestyle, or facilitate constructive conversations with family members and friends. Implementing effective climate solutions relies on an informed public, and climate education provides youth with a starting point to act as agents of positive change amidst our planetary emergency. 

Additionally, climate education can provide youth with the tools necessary to alleviate and cope with climate anxiety. A 2021 Lancet Study asked 10,000 young people between the ages of 16–25 in ten countries what they felt about climate change, and found that more than 50% of young people reported experiencing sadness, anxiety, anger, powerlessness, helplessness, and guilt. Effective climate education will not only help youth understand the causes and impacts of climate change, but it will also provide young people with insight on how they can contribute to solutions and exercise their own agency to make meaningful changes. Further, climate education can provide coping strategies by fostering hope and highlighting the collective efforts being made to address climate change. 

Barriers to Effective Climate Education 

According to an article from Science, data from 1500 public middle- and high-school science teachers from all 50 US states found that the median teacher devotes only one to two hours to climate change instruction. Climate confusion among U.S. teachers further contributes to this educational gap within American education, and limited training and scientific consensus among teachers leads to mixed messages. For example, the research published in Science found that of the teachers who teach climate change, “31% report sending explicitly contradictory messages, emphasizing both the scientific consensus that recent global warming is due to human activity and that many scientists believe recent increases in temperature are due to natural causes.” Progress in climate science and scientific consensus have outpaced teachers’ training. Additionally, teachers may face political threats and external pressures from parents or administration to avoid climate instruction. 

Teachers’ lack of knowledge on climate science and exclusion of climate instruction is further compounded by variations in learning standards and requirements. Climate education within the US faces challenges due to the absence of consensus on the inclusion of climate change in educational curricula and the absence of national science standards on the subject. In 2013, the Next Generation Science Standards (NGSS) were developed and recommended that human-made climate change be taught in all science classes beginning in fifth grade. However, these standards remain voluntary, and 44 states have used the NGSS or created standards based on them. Since 2007, The Campaign for Environmental Literacy has continued to organize stakeholders and push for passage of the Climate Change Education Act, leading to the subsequent efforts to reintroduce and pass the bill four times since then. Despite these efforts, federal grants to fund climate change education projects have been miniscule and initiatives in Congress to support climate change education have been unsuccessful. New Jersey became a pioneer in climate education in 2020, becoming the first state to mandate the teaching of climate change beginning in kindergarten. Notably, New Jersey has taken an interdisciplinary approach to climate education as students are learning about climate change in ceramics and physical education classes. 

Making Climate Change Education Accessible and Engaging for Youth

Outside of the traditional classroom setting, many environmental organizations, activists, content creators, and informal education institutions like museums or zoos provide opportunities for students to engage in climate education. Collectively, these actors play critical roles as environmental educators who bridge the educational gaps related to climate change and increase climate literacy amongst young people. In an era dominated by digital communication, media serves as a dynamic and influential tool in climate education initiatives. In a survey conducted by the EdWeek Research Center, social media emerged as the third most frequently mentioned source of information on climate change amongst teenagers. Young people consume climate-related media through various social media platforms, like YouTube, Instagram, and TikTok. Environmental educators understand that leveraging various forms of media allows them to create engaging, relatable, and inspiring climate education for today's youth. While leveraging these platforms to educate youth and the wider public on climate change, storytelling remains a central element. Media-driven climate education empowers environmental educators to effectively break down barriers and make climate science more accessible, relatable, and inspiring for youth of all ages.

Since the Industrial Revolution, our soils have lost between twenty and sixty percent of their carbon levels as a result of agricultural practice exacerbated by more common and more extreme droughts and floods resulting from climate change. Farmers have witnessed their crops endure mass devastation as a result of these unprecedented environmental disasters. Hence, the loss of carbon in soil threatens the stability of both the agriculture industry and global food security. 

Why Does Soil Need Carbon?

Stable carbon storage in soil is crucial for healthy soil and supports resistance to climate vulnerability. But how? A 1% increase of carbon in soil equates to a two percent increase in its water-holding capacity, in turn creating more drought-resistant soil that can better weather extreme climate variability. By enhancing its water-holding capacity, as well as nutrient retention rates, stable carbon contributes to both the structure and function of soil. Consequently, soil health and productivity are contingent on soil’s carbon content. By recognizing that stable carbon storage within their soil can lead to more nutrient-dense crops and bigger yields, farmers have a clear economic incentive to seek agricultural solutions that can reduce the current rate of carbon loss their crops are experiencing.

The Future of Fungi: Building Resilient Soil Ecosystems

Based in Orange, New South Wales, Australian biotech start-up Loam Bio has developed a new way to remove carbon dioxide from the atmosphere and store it underground. The solution, a microbial fungi-based seed treatment, is far less complex than one might initially think, simply requiring farmers to sprinkle the ground-up dust of fungal spores onto seeds actively used in their planting systems. As crops grow from those seeds, the fungal spores attach themselves to the roots. The tendrils of the fungus then extract the carbon that has been absorbed by the crop it latched onto.

Plants, on their own, sequester carbon from the atmosphere—a process crucial to mitigating fossil fuel emissions. The microbial fungal treatment leverages that sequestration by reducing the plants’ natural emissions of carbon. This particular type of microbial fungi, therefore, provides a level of protection against standard plant respiration, thereby reducing the amount of carbon returned to the atmosphere and instead storing it in soil for a longer period than the natural carbon cycle. 

Loam Bio relies on a cross-disciplinary team ranging from geneticists to mycologists to plant physiologists to carbon methodology experts. For example, the fungi and other organisms involved in the treatment are pre-screened through a genetic selection process that evaluates whether they are safe to introduce to the agricultural landscape and can effectively interact with the herbicides and fertilizers that may be used in crop production. The success of the fungi, however, is ultimately dependent on the soil type and the climatic environment of the respective farm to which it is being applied via seed treatment. 

Soil Expert Skepticism

While there is hope within the science community for the potential of the uptake of carbon in soil as a climate solution, some experts remain skeptical of whether the use of microbial fungi in field tests will translate to a meaningful impact on the carbon release of crops on operational farms.  Further testing and monitoring will be required for a full evaluation of the benefits and impacts.  

The agriculture industry relies on intensive farming practices that are increasingly worsening soil erosion and overall decreasing the quality of farming soil, including depleting the soil’s carbon content. Loam’s Bio initiative provides one possible pathway to try and reverse this consequence of industrial farming. So far, Loam Bio has had some encouraging results, achieving soil carbon content levels of 6%—far surpassing the US average of 1-4%. This revolutionary treatment has the potential to transform soil into an invaluable carbon sink, even more than it is now.

The Decline of Arctic Sea Ice

As climate change heightens temperatures and alters climatic conditions, summer sea ice in the Arctic is melting rapidly. By the mid 2030s, it is predicted that a “Blue Ocean Event” (or BOE) will occur, meaning that the Arctic Ocean is expected to have less than one million square kilometers of sea ice. This equates to just 15% of the Arctic’s seasonal minimum ice cover of the late 1970s. As ice continues to melt, more of the ocean will be exposed to the sun's rays, thus absorbing more heat and accelerating warming. The Arctic has warmed four times faster than the rest of the world since 1979, largely due to this positive feedback loop known as Arctic amplification. Since the 1980s, the amount of Arctic sea ice has declined by approximately 13% each decade. As the BOE unfolds, it will trigger significant impacts, including droughts, heatwaves, accelerated thawing of terrestrial permafrost (releasing emissions in the process), and sea level rise. The Arctic plays a critical role in climate stabilization by acting as a large reflective surface, helping to cool the planet and maintain a stable global temperature. The BOE is thus a major climatic tipping point with catastrophic global consequences. A new methodology has been proposed to protect and restore Arctic sea ice known as Aqua Freezing. This approach uses renewable energy-powered pumps to distribute seawater on existing Arctic ice, allowing it to refreeze and thicken, helping to maintain climatic stability.

The plan aims to target over 386,000 square miles of Arctic sea ice, an area larger than California. The process of refreezing already shows promise in field tests conducted over the past two years in Alaska and Canada. Proponents of refreezing Arctic sea ice believe that this technique would buy the region time while we make the necessary emissions cuts to curb the impacts of climate change. Refreezing ice would also preserve the albedo effect, which reflects sunlight back into space, preventing warming. 

Although AquaFreezing offers a potential solution to combat Arctic melting, scientists and policymakers doubt whether sea ice can be grown over a long enough period to make a true difference in the climate crisis. Further, the project is quite costly, equating to over 5 trillion dollars and demanding more steel than the US produces in a single year. The project would require 10 million pumps; however, this would only cover 10% of the Arctic Ocean’s roughly 4 million square mile size. To cover the entire area would require 100 million pumps and roughly 100 million tons of steel each year. The US currently produces around 80 to 90 million tons of steel a year, so covering just 10% of Arctic ice would require 13% of US steel production. The production required for the project could lead to immense environmental degradation and added emissions in the process.

Simon Woods, co-founder and Executive Chairperson of Real Ice, is hopeful that this solution will buy the region time while we make the necessary emissions cuts to curb climate change. Real Ice believes this innovative solution can preserve sea ice and thus work to combat climate change.

Across the United States, evangelical Christians are increasingly forging a connection between faith and climate action by redefining environmental work as a sacred duty to care for God’s creation. By understanding sustainability through the lens of biblically mandated stewardship, more and more Christians are discovering renewed hope and purpose in addressing climate change.

What Is Creation Care?

To many evangelical environmentalists, caring for the Earth is not a political act. Rather, it is a spiritual duty. They believe that how we treat the planet should reflect how God treats us: with compassion, responsibility, and reverence. That means resisting the exploitation of natural resources and instead treating the Earth as a divine gift entrusted to humanity.

Historically, however, environmentalism and climate science have been viewed as controversial in conservative Christian circles, seen as secular or partisan issues. But that perception is beginning to shift, thanks in part to young leaders and faith-based environmental advocates who are reframing climate action as a moral and theological imperative.

Faith in Action

One of those young leaders is Becca Boyd, a student at Indiana Wesleyan University studying Environmental Science. Raised in a Christian home, Becca often felt her environmental concerns were dismissed and even challenged. Feeling unhead, she began to experience a crisis of faith, questioning both her faith and her place in the church.

Everything changed when she was introduced to the concept of creation care in college by her professors. For the first time, she saw how her love for the environment and desire to protect it could be an act of faith rather than in conflict with it.

A Theology of Hope

Like many young people in the climate action space, Becca has felt overwhelmed by the constant sense of “doom and gloom.” The narrative that it’s too late to fix the damage can leave people in despair and feeling helpless. But creation care offers her a more hopeful, spiritually grounded mindset. Rather than dwelling on what’s broken, Becca focuses her energy on healing what’s still possible.

For Becca, environmental stewardship is now a form of worship: small acts like conserving energy, recycling, or planting a pollinator garden at her school are ways of honoring God.  And by inviting others to do the same, she’s helping grow a climate movement rooted not in fear but in faith and hope for the future.

Choosing Words That Open Doors

Through her advocacy, Becca has learned that the language you use to talk about climate issues matters, especially in Christian spaces. The word “climate” itself can be politically charged and can trigger defensiveness, while terms like “creation care” and “eco-theology” feel more rooted in faith and shared values.

She is also intentional about her tone, making a point to avoid “you” statements. Rather than telling people what they should do, Becca shares what she does and why. This approach opens the door to conversation rather than closing it. According to Becca, it’s about meeting people where they are and establishing a common ground — inviting them in, not calling them out. 

The Challenges Ahead

Creation care is still a growing movement, and while it’s gained traction in places like Indiana, there’s still a long way to go. Climate science skepticism and misinformation continue to circulate in many conservative communities. But Becca and other young Christians are starting vital conversations in churches and on campuses, emphasizing climate change as a humanitarian issue: one that affects food security, public health, and the lives of future generations. 

She also shares resources like Cowboy & Preacher, a documentary tracing the history of Christian environmentalism, to show that this movement isn’t new, and that faith and climate action have long been intertwined. 

About Our Guest

Becca Boyd is a rising senior at Indiana Wesleyan University studying Environmental Science. She is a Climate Advocate for Young Evangelicals for Climate Action (YECA) and previously served as a College Fellow. On campus, she launched a student sustainability club and helped lead campus-wide conversations about the intersection of faith and environmental responsibility. She was recently featured in The New York Times for her work advancing Indiana’s growing creation care movement.

As defined by the U.S. Geological Survey, “carbon mineralization is the process by which carbon dioxide becomes a solid mineral, such as a carbonate…The biggest advantage of carbon mineralization is that the carbon cannot escape back to the atmosphere.” This generally occurs by injecting carbon dioxide underground into certain rock formations so the carbon dioxide takes on a solid form: trapped and unable to reach the atmosphere. 

How does carbon mineralization work?

Two of the main methods in which carbon mineralization occurs are ex-situ carbon mineralization and in-situ carbon mineralization. With ex-situ carbon mineralization, carbon dioxide solids are transported to a site to react with fluids—like water—and gas. In-situ carbon mineralization is the opposite—fluids containing carbon dioxide are funneled through rock formations in which it solidifies. Both of these methods result in carbon dioxide trapped in a solidified form. 

In a third method of carbon mineralization, surificial mineralization, carbon dioxide reacts with alkaline substances—such as mine tailings, smelter slags, or sedimentary formations—which result in the carbon dioxide taking on a solidified form. In the case of in-situ carbon mineralization or surificial mineralization, carbon dioxide can react with surface water rather than an artificial fluid, replicating natural processes of carbon mineralization.

Currently, the biggest drawbacks and barriers preventing carbon mineralization from taking hold as a major climate solution lie in cost and research uncertainties regarding environmental risks. In terms of cost, the price for carbon mineralization is high: 5 million dollars per well to inject carbon dioxide into rock formations. Further, the risks for groundwater and its susceptibility to contamination through this method is unknown, and the potential side effects of contaminating water formations could be devastating for ecological communities which thrive off of these water systems.

Many of the solutions we often hear about when it comes to reducing greenhouse gas emissions revolve around reducing carbon emissions, as carbon dioxide (CO2) is the primary greenhouse gas emitted by human activities. Methane, however, is the second most common greenhouse gas, emitted through agricultural practices, landfill waste, coal mining, and oil and gas operations. While methane generally receives less attention than carbon dioxide when it comes to climate solutions, recent studies have shown that it is a more potent greenhouse gas than carbon dioxide. According to the United Nations Economic Commission for Europe, methane has a global warming potential 28-34 times higher than CO2 upon emission, which increases to 84-86 times over a 20-year period. 

How does methane enter our skies?

The concentration of methane in the atmosphere has more than doubled over the past century. Both everyday infrastructure in older cities and major leaks at oil and gas fields add to the quantity of methane into the atmosphere. As for the source of these leaks, they are largely caused by equipment failures or faulty pipes and vessels. 2,595 gas incidents have been reported in the US from 2010 to 2021, adding up to 26.6 billion cubic feet of methane gas emitted. Methane impacts both the climate system and public health; breathing methane can cause damaged airways, lung diseases, asthma attacks, increased rates of preterm birth, cardiovascular morbidity and mortality, and heightened stroke risk.  

What can we do?

Mining operations can be improved to reduce methane leaks and oil and gas operations can greatly reduce emissions throughout the system. As our tools of measurement and technology improve, the world has realized the greater need to attack methane emissions, which led to the Global Methane Pledge in 2021. In this pledge, 158 countries and the EU pledged to make a distinct effort to reduce global methane emissions by at least 30 percent from 2020 levels by 2030. 

Part of reducing methane emissions involves switching from fossil fuels to electricity generated from renewable sources.  According to Environmental specialist and Stanford professor Dr. Rob Jackson, our skies will become cleaner once we switch to cleaner, electrical energy sources, including electric heat pumps to cool and heat our homes, electric water heaters, and especially electric stoves. According to the Journal of Environmental Science and Technology, methane emissions from gas stoves in America—when scaled to the 20-year global warming potential of the gas—were “comparable to the carbon dioxide emissions of approximately 500,000 gas-powered cars.” Health-wise, a study conducted by Stanford’s Doerr School of Sustainability and PSE Healthy Energy found that “children who live in homes with gas stoves had a 24% higher risk of lifetime asthma and a 42% increased risk of having asthma currently.” Dr. Jackson says that making the switch to induction stoves is not only energetically cleaner and prevents the likelihood of gas leaks, but it also prevents us from being exposed to toxic pollutants such as nitrogen oxides and benzene gasses that come from gas stoves.

Some potential drawbacks: the cost of electricity

While induction stoves and a cleaner, electrical society sounds optimal, there are some challenges and barriers to making this a reality. First of all, not every person can afford to implement an induction stove and replace their functioning gas stove, as home renovations, rewirings, and big purchases such as a new stove cost a great deal of money. In this way, income inequality plays a major role in the way climate change impacts different people in society. Dr. Jackson uses the example of a person living in a lower-income community; surrounded by older, poorly-maintained appliances, people in these types of homes often breathe dirtier air indoors than outdoors. This is why Dr. Jackson proposes that the shift to clean energy be gradual; fueled by regulations and government support. Without social support, equal access to cleaner energy cannot be achieved.

In terms of major gas leaks, change is hard to make as an individual. According to the Environmental Defense Fund, the best thing we can do is to fight for national policy to repair and prevent leaks wherever they occur: whether at mining facilities or under our sidewalks. This is a difficult task, as all individuals can do is push for political action, however agreements such as the Global Methane Pledge seem to be steps in the right direction.

In the transition to clean energy, state public utility commissions (PUCs), which regulate electric, gas, telecommunications, water and wastewater utilities, play an increasingly important role in achieving energy efficiency, enabling renewable energy, and implementing policies for greenhouse gas emissions reduction. PUCs  play a pivotal role in determining the energy mix, setting rates, and deciding on investments in infrastructure, such as electric vehicle (EV) charging stations. The California Public Utilities Commission (CPUC), for example, has to balance  safety, reliable utility service, and reasonable rates through the regulation of various large investor-owned electric, natural gas, and water utilities. Utility commissions like CPUC are given a statutory mandate to ensure reasonable, adequate and efficient service to customers at just and reasonable prices. PUCs can issue regulations that impact electricity generation, the adoption of clean energy, and related emissions of pollutants and GHGs. PUCs can play an important role in shaping energy infrastructure, policy, and clean energy development.

The Role PUCs play in shaping energy infrastructure

PUCs were first created in the early 20th century to focus on overseeing operations and the utility investment in service while ensuring affordable rates. That role has evolved, and now PUCs often play a transformative role in transitioning towards a greener economy. PUCs have the ability to consider the impacts of GHG emissions, equity, grid reliability, distributed energy resources, and increased consumer choices in their policy decisions. 

PUCs oversee planning processes that affect a utility’s resource portfolio and therefore its environmental profile. A new method of planning amongst PUCs has emerged known as Integrated Resource Planning (IRP), which compares the life cycle costs of different resource choices that factor energy efficiency into their analysis. Portfolio standards have also been added to IRP, which requires certain types of resources to be included in the utilities’ mix of power procured, including renewable energy and energy efficiency. PUCs can also incorporate environmental considerations by increasing oversight of utility planning processes, setting prices, determining clean energy targets, and addressing utility incentives related to energy efficiency and distribution. PUCs thus have the ability to promote and shape clean energy adoption and development through their regulatory oversight. 

The Case for PUCs

State PUCs have significant authority, often includingI the ability to accelerate decarbonization of the energy sector, mitigate the impacts of climate change, improve public health, and assist in reaching state energy goals. Updated PUC statutory mandates that reflect state energy priorities can contribute to their success in transforming the energy grid to become more energy efficient. Energy efficiency is a cost-effective mechanism to meet future demand for electricity. Energy efficiency reduces the amount of electricity needed to meet demand thereby benefiting the overall reliability of the electric grid. With more efficient systems, utilities and states will not need to build as much new transmission and generation, which can save money and improve environmental quality. Further, modern regulations to achieve such priorities and framing for the public interest can incorporate climate and environmental justice concerns. 

The Case Against PUCs

Organizational challenges such as outdated mandates, staff constraints, gaps in technical knowledge, misinformation, and quasi-judicial processes have created barriers to innovation amongst PUCs. Some PUCs still continue to view themselves as purely economic regulators, which does not accurately reflect the current decisions they are being asked to make. Additionally, the authority of PUCs varies widely from state to state. PUCs authority is established by state legislatures, thus their power only extends as far as their statutory authorization. The level of statutory authority delegated to PUCs by legislatures also varies widely. Barriers such as these have made it difficult for some  PUCs to develop more innovative mechanisms consistent with new environmental targets and the effort to achieve a zero-carbon US grid.

While transitioning to clean energy promises long-term savings and environmental benefits, the short-term costs can be significant and potentially burdensome for consumers and businesses, posing political and fiscal challenges for PUCs. Stakeholder engagement in this transition will be vital. Labor issues also pose challenges as states transition away from  fossil fuels. In addition, challenges exist around regulatory complexities and the evolving federal and state policies.

Climate or “eco” anxiety refers to people feeling distressed about climate change and its impacts on our ecosystems, the environment, and human health and well-being. It is rooted in a deep existential dread concerning the future of the planet. Symptoms include feelings of grief, loss, anger, sadness, and guilt, which in turn can cause jitteriness, nervousness, increased heart rate, shallow breathing, difficulty concentrating, changes in appetite, or insomnia due to worry or concern about the effects of climate change. 

According to Grist, Google searches for “climate anxiety” soared by 565 percent in 2021. And according to the Yale Program on Climate Change Communication, an all-time high of 70 percent of Americans express worry about climate change. In September 2021, the largest study of its kind found that the climate crisis was causing widespread psychological distress for young people between the ages of 16 and 25 across 42 countries from both the global North and South. Over 45 percent of teens and young adults said that climate anxiety was affecting their daily lives and ability to function; 56 percent said they thought that "humanity is doomed" and nearly 4 in 10 said that they were hesitant to have children because of climate change. 

From Solastalgia to Soliphilia: how Native American Ecology can lead the way

The steps people must take to address their climate anxiety depends on each individual, as people are affected by climate change in different ways. For example, some people have lost homes or even loved ones, while many others have witnessed these catastrophic events unfold on their phone screens.

Dr. Melinda Adams describes this trauma as “solastalgia,” originally coined by Australian philosopher Glen Albrecht to describe the distress caused by the destruction or loss of one’s home environment. This concept helps people to understand and express the “psychoterratic,” or the relationship between human mental health and the earth’s own well-being. Many have taken legal and political action to deal with their solastalgia. For example, last year Montana youths sued the state for its failure to recognize that approving fossil fuel projects was unconstitutional without further review of the impacts to the climate. Others have drastically altered their lifestyles, opting instead to practice underconsumption to limit their personal contributions to the changing climate. 

Dr. Adams has another solution, reminding those who suffer that the definition of solastalgia also includes hope. Hope can lead us either into action or ecoparalysis. It is within this framework that Dr. Adams introduces Native American cultural burnings as a way to achieve soliphilia, “the political affiliation or solidarity needed between us all to be responsible for a place, bioregion, planet, and the unity of interrelated interests within it.’’ 

Cultural fires or “good fires,” which involve lighting low-intensity fires to heal the surrounding ecosystem, can exemplify this step. Not only do these fires restore degraded soils, decrease vegetation or fuel overgrowth, encourage re-vegetation and biodiversity, but they also deepen the spiritual ties people have to the land they inhabit. Fire therefore has a regenerative power, both spiritually and ecologically, as participants share stories and strengthen communal and spiritual bonds with one another during these ceremonial burnings. As a member of the N’dee San Carlos Apache Tribe, Dr. Adams takes Glen Albrecht’s theory of the “psychoterratic” and frames it as a relationship between siblings. Subsequently, as siblings, humans and the land must help each other survive. By treating the earth as a more-than-human sibling, and by practicing cultural burns, participants can begin to heal from their solastalgia. 

Directly engaging with a regenerative process such as “good fires,” “grounds people’s intentions and allows for deeper connections—to place and among one another.” “[C]eremonial fires create opportunities for social, environmental, and cultural healing among young persons (Native and allied)” (Tom, Adams, & Goode at 3). Essentially, the strengthening of community through spiritually uplifting activities alleviates climate anxiety by showing young people that there are people out there who share their concern for the climate and are motivated to do something about it. 

Who is our guest?

Dr. Melinda Adams is a member of the N’dee San Carlos Apache Tribe and an Assistant Professor in the Department of Geography and Atmospheric Science at the University of Kansas. A cultural fire practitioner and scholar, her research focuses on the revitalization of cultural fire with Tribes in California and more recently with Tribes in the Midwest. Her work with Indigenous communities combines environmental science, environmental policy, and Indigenous studies methodologies. Read more about Dr. Melinda Adams here.

The  Latino Climate Justice Framework (LCJF) prioritizes environmental justice while helping to protect disproportionately affected individuals–commonly Latine people. Specifically, LCJF works with communities that “face numerous climate-related issues, from extreme heat affecting outdoor workers and poor air quality in neighborhoods near industrial facilities, to increased vulnerability to natural disasters like hurricanes, floods, and wildfires.”

The Particulars

LCJF has three areas of focus with different goals for how to better the health of the environment and the Latino community. Chapter one of the LCJF identifies how fossil fuels disproportionately expose the Latine community to toxic pollutants. LCJF believes that carbon capture methods are an extremely passive solution that do not address the problem; instead they hope to prioritize renewable energy while enhancing affordability and accessibility to these amenities by “ramping up recycling, reusing batteries and solar panels” and “ensuring equitable investment”.

The second chapter outlines how “latinos are 21% more likely than white individuals to reside in urban heat islands” and “only 19% of Latino/a/e children have nearby recreational green spaces, compared to 62% of white children.” They follow up with recommendations for how they hope that plans for “prioritizing urban greening projects in Latine neighborhoods with the highest heat risk and lowest tree canopy and green spaces” would improve air quality in their neighborhoods, while reducing health risks. 

The last chapter outlines how Latines have an extremely sacred relationship with land and water.  However, due to “patriarchal and white supremacist oppression” they have been deprived of their access to nature. Moreover, they acknowledge that Earth has been losing vital biodiversity for those very same reasons. Thus, they hope to reduce this problem by opposing efforts to extract natural gas and oil, build the US Mexico border on sensitive lands, and “sprawl development on public lands.”

The Upsides 

The LCJF aims to mitigate climate change by reducing pollution from fossil fuels through stringent regulations and promoting clean energy alternatives. It emphasizes the development of climate-resilient infrastructure to protect communities from climate-related disasters. Additionally, the framework seeks to empower Latine communities by involving them directly in environmental decision-making processes, ensuring that solutions are culturally relevant and effective.

Foreseeable Difficulties in Utilization

Though potential issues may include challenges with implementation, funding, political support, scalability, and policy adaptation efforts. LCJF Program Director Irene Burga argues that Latine people are often kept out of the conversation of climate equity despite the fact that they are extremely affected by climate change. If their voices are heard, she says, climate policies would be much more impactful.

Since the pre-industrialized era, the global temperature has increased by about one degree Celsius. Although one degree may not seem significant, the consequences are increases in the intensity of heatwaves and drier conditions. In addition, in dense urban settings buildings trap and absorb this heat and cause even a higher area of heat relative to surrounding areas. The heat island effect is also exacerbated by the lack of greenery. With current fossil fuel emissions, increased heating of 1.5 degrees Celsius or more is predicted to happen globally within this decade. Among the most promising solutions to combat extreme heat in cities is the effort to promote natural systems – trees, creeks, and parks in cities and creating resilience hubs where people can stay cool and safe from dangerous temperatures.  Because heat impacts individuals in multiple ways, the response to extreme heat must also be multifaceted.  

Responses to Extreme Heat

There are many possible responses to extreme heat. On an individual level, for example, when human body temperature rises to the point of heat stroke, individuals are subject to serious illness or in some cases, death.  Heat poses a particular threat when the body is physically unable to cool down. According to the World Health Organization (WHO), between 2000 and 2016, 125 million more people were exposed to heat waves than in the period before 2000. Actions individuals can take to reduce heat exposure include avoiding going outside at peak temperatures, reducing the heat inside of homes, and if reducing heat at home is not an option, going where air conditioning is available. 

For some vulnerable populations like farmworkers, staying inside where there is air conditioning is not an option. In some states, like California, a temperature of 80 degrees Fahrenheit initiates the California's Heat Illness Prevention Standard, which is enforced by the Occupational Safety and Health Administration (OSHA).  The Standard requires that training, water, shade, and rest be provided to outdoor workers. Currently, there is no federal protection or policy for workers who may experience extreme heat. While a proposed rulemaking is in the works, it may take years before a final regulation is completed.

How to Establish Resilience and Safe Hubs

In the meantime, there are key actions that anyone can take, including something as simple as making extreme heat a topic of discussion as part of increasing awareness. By spreading awareness and recognizing the consequences of extreme heat, politicians and policymakers will be much more likely to pay attention to the issue and to community necessities. Global and local temperatures are continuing to rise, and, as a result, it is important to have community access to locations with air conditioning systems, heat pumps, and safety hubs particularly in communities whose residents do not have home air conditioners. Hubs may include libraries, churches, schools, and nonprofits which can be essential for providing both a cool place to shelter and a source of information and assistance.

Shifting to more green spaces is also an important solution to mitigate the impacts of increased heat. In New York, the Highline is a great example of transforming an old historic freight rail line into a park filled with rich greenery. The incorporation of nature into a previously urban dense space provides the city with more trees and access to green space. 

Addressing extreme heat in cities requires new approaches and creative thinking for a suite of implementation strategies to provide cooling to the public and creation of green space.

Extreme heat, one of the adverse consequences of climate change, exacerbates drought, damages agriculture, and profoundly impacts human health. Heat is the top weather-related killer in the United States, contributing to deaths that arise from heart attacks, strokes, and other cardiovascular diseases. As temperatures are projected to increase, so will the risk of heat-related deaths. Urban heat islands, cities with large numbers of buildings, roads, and other infrastructure, are ‘islands’ of hot temperatures due to the reduced natural landscape, heat-generating human-made activities, and large-scale urban configuration. More than 40 million people live in urban heat islands in the United States, with this number only increasing as people continue to move from rural to urban areas. Around 56% of the world’s total population lives in cities. Those living in large cities are more vulnerable to the effects of extreme heat, with research showing an increased mortality risk of 45% compared to rural areas. The risk of heat-related exhaustion and death is a major public health concern that is exacerbated by the climate crisis. 

The National Weather Service is in the process of creating a new interface known as HeatRisk, which uses a five-point scale to monitor the heat-related risk for vulnerable populations based on local weather data and health indicators. By mapping heat risk, climate scientists hope that individuals will now have a better understanding of the safety concerns associated with being outside during times of extreme heat. 

Understanding Heat Index Dynamics

Before stepping outside, most individuals check the daily weather prediction to get a sense of the average temperature. In order to measure the perceived temperature, climate scientists use a heat index, a calculation that combines air temperature and relative humidity to create a human-perceived equivalent temperature. Accurate prediction of the heat index is imperative as every passing year marks the warmest on record, with dangerous extreme heat predicted to become commonplace across arid regions of the world. Therefore, tracking such calculations is necessary in assessing future climate risk. Areas especially vulnerable to extreme heat heavily rely on an accurate prediction of temperature to determine if it is safe to go outside.

However, there are over 300 heat indexes used worldwide to calculate the threat from heat, defeating the potential universality of this metric. Each heat index weighs factors differently, making it difficult to differentiate between various metrics. Dozens of factors are used to estimate the daily temperature based on predictions of vapor pressure, height, clothing, or sunshine levels. In addition, most heat indexes report the temperature assuming that you are a young, healthy adult and are resting in the shade, not in the sun. If outdoors, the heat index could be 15 degrees higher. If you are older, you may not be as resilient during intense temperatures.

As a result, many climate scientists are calling for heat indexes that reveal the apparent risk of being outdoors on any given day. The elderly, children and infants, and those suffering from chronic diseases are more vulnerable to high temperatures than healthy, young adults, which needs to be accounted for when surveying temperature risk. 

Advanced Heat Assessment Tools: HeatRisk and WBGT

The National Weather Service’s HeatRisk index is different from previous models as it identifies unusual heat times and places, also taking into account unusually warm nights. As such, it provides a more universal measure accounting for the degree to which people in the area are acclimated to various heat temperatures. The HeatRisk index can thus be used to gauge levels of danger associated with temperature, potentially altering an individual’s behavioral patterns. 

For those working in outdoor fields, the WetBulb Globe Temperature (WBGT) measure can be particularly useful as a way to measure heat stress as it takes into account temperature, humidity, wind speed, sun angle, and cloud coverage. Different from the heat index, the WBGT includes both temperature and humidity and is calculated for areas in the shade. If not exercising or working outdoors, people can revert to the HeatRisk scale to calculate the potential hazards of being outside for longer periods. 

Heat Indexes are Harder to Calculate Than They Appear

Because scientists have to account for a variety of factors like geography, physics, and physiology, establishing a truly universal heat index is unlikely. For regions like Colorado, creating the criteria for a heat advisory has proven shockingly difficult. Heat indexes typically rely on temperature and humidity, however, the Colorado landscape is so dry that an advisory is very rarely triggered, even during heat waves. In such scenarios, the HeatRisk index provides a better gauge for outdoor safety. Most people underestimate the dangers of extreme heat and often ignore warning messages from local authorities. Educational programs are vital in informing the public on the dangers of extreme heat.

Who is David Romps?

David Romps, UC Berkeley professor of Earth and Planetary Science, is at the forefront of heat index research. Romps has found that those exposed to extreme heat suffer restricted blood flow and are often unable to physiologically compensate. Through his research, Romps believes that heat index calculations often underestimate the potential heat impacts on individuals, with the human body being more susceptible to heightened temperatures than commonly understood.

North America is no stranger to wildfires. As of August 15, 2024, 29,917 fires this year have burned more than 5.2 million acres, according to the Center for Disaster Philanthropy. While this year’s number of wildfires is below the annual average of 35,691, the yearly acres burned is above the average of 3.8 million acres of the past 10 years.

While wildfires are a naturally occurring phenomenon, their frequency is heavily influenced by climate change, especially on the west coast of the United States. Wildfire risk increases depending on a number of factors, including temperature, soil moisture, and the presence of trees, shrubs, and other fuel. Additionally, climate change dries out organic matter or “fuel” in forests, resulting in a doubling of the number of large fires between 1984 and 2015 in the western United States. As climate change creates warmer and drier weather conditions, wildfires will likely become more frequent; studies show that an average annual warming of one degree celsius would increase the median burned area per year by as much as 600 percent in some types of forests. 

Ultimately, as temperatures warm globally and drier conditions ravage the country, these fires will spread farther and become harder and harder to extinguish. 

“Good” fire: an ancestral solution to our wildfire problem  

As the planet warms, many have turned to ancient methods to mitigate the effects of climate change. Notably, Dr. Adams borrows the concept of “good” fires from Native American cultural fires practices, where low intensity fires are lit to heal the surrounding ecosystem. In order to positively change the public’s relationship with fire, fire agencies in California and Native American tribes have started using this term. Generally, “good” or cultural fires not only restore degraded soils and decrease vegetation or fuel overgrowth, but also deepen the spiritual ties people have to the land they inhabit. Specifically, good fire increases organic matter, keeps soil surfaces vegetated through the regrowth of plants, and encourages biodiversity. 

In California, many ecosystems rely on fire for its regenerative powers. Dr. Adams notes that fire connects to water, soil health, and the health of animals and surrounding areas. It can also mitigate invasive species growth and eliminate harmful pests that are killing a lot of trees, making them more susceptible to catching fire and starting larger forest fires. As a result, fire promotes many benefits for ecosystem health.

Dr. Adams writes that as a member of the N’dee San Carlos Apache Tribe, she maintains a sacred attachment to the land, and believes that humans and the Earth are relatives. Subsequently, as siblings, humans and the land must help each other survive. Following these teachings around our relationship to more-than-human sibling and reciprocity, “good” fire participants can achieve “futurity” (intergenerational exchanges) that will safeguard future protection of the environment and human communities. Listening to these Native American Traditional Ecological Knowledge (TEK) could lead the way to developing a more sustainable relationship to the planet and, in doing so, mitigate the effects of climate change.

Mother Earth: how climate matriarchy can save the planet 

The concept of “good” fire stems from Indigenous Matriarchal Ecology. Many Native American tribes are matriarchal, such as the Cherokee and the Navajo. Applying traditionally “matriarchal” values such as care, tenderness, and love to environmental conservation could be an effective climate change solution. Inclusivity and the centering of Indigenous women’s knowledge can also allow opportunities to enhance plant and soil health, remediation, and rematriation of the quality of our plant and soilscapes to provide a prosperous support structure that enables ecosystems to thrive.

By practicing Indigenous Matriarchal Ecology, cultural fire participants can collectively start seeing the Earth as a Mother: one who gives life and receives it in return. This is why Dr. Adams and her colleagues focus on the role the soil can play in the fight against climate change through the practice of Matriarchal Ecology. Dr. Adams writes that applying a soil health approach to ecology in tandem with cultural fires can play an important role in climate mitigation by storing carbon and decreasing greenhouse gas emissions. By restoring degraded soils and adopting soil conservation practices, such as cultural fire and Indigenous Matriarchal Ecologies, “good” fire practitioners can enhance the Earth’s carbon sequestration capacity and build resilience to climate change. Furthermore, these soil improvements on formerly mined and degraded lands could make soilscapes more resilient to erosion and desertification, while maintaining vital ecosystem services. And hopefully, these practitioners can inspire others, non-Native and Native alike, to develop a better understanding of and relationships with the planet.

Indigenous Matriarchal Ecologies can highlight the positive effects of cultural fire on environmentally degraded soils, while simultaneously building native plant and soil resilience toward climate and cultural futurity that all communities can enjoy.

A 2022 IPCC report found that direct GHG emissions from the transport sector accounted for 23% of global energy-related CO2 emissions in 2019. Road vehicles accounted for 70% of direct transport emissions, while 1%, 11%, and 12% of emissions came from rail, shipping, and aviation, respectively. 

As the mounting effects of climate change continue to be felt worldwide, the aviation industry is pioneering a method to reduce its contributions. Namely, it is focusing on efforts to curtail condensation trails – or contrails – which are fluffy, white cloud formations that sometimes appear as airplanes fly through the cold, humid, and icy parts of the atmosphere. Because they are a combination of soot, water vapor, and particulate matter (such as NOx), when aircrafts pass through these areas, they form cirrus clouds that absorb the radiation escaping from the surface, and, in turn, trap the heat. 

This phenomenon could account for around 35% of aviation’s total contribution to climate change — that’s about 1 to 2% of overall global warming! Together, these contrails roughly triple the total global warming impact of aviation compared to CO2 alone. Therefore, it is imperative that the aviation industry find solutions to reduce the production of contrails. 

What the industry has come up with: 3 solutions 

One method of reducing contrails consists of replacing traditional fuels with biofuels made from plant or animal biomass, waste, sugars and ethanol (corn). Sustainable jet fuels can produce 50%-70% fewer contrails according to research conducted by NASA and the German Aerospace Center (DLR). Jets using alternative fuels release fewer soot particles, thereby creating fewer ice crystal formations, which ultimately reduces contrail production by extension. Though biofuels may initially form larger crystals, they fall more quickly and melt in the warmer air below.

The second method involves developing electric or hydrogen-powered commercial aircrafts. Hydrogen is an attractive alternative to traditional aircrafts because it can be burned without emitting CO2 and is widely available. These aircrafts would either burn liquid hydrogen directly into their engines, or use gaseous hydrogen in a fuel cell system. With fuel cells, the hydrogen creates an electrochemical reaction that produces electricity to charge the aircraft's batteries while in flight. 

A third method involves redirecting flights to avoid contrail-inducing zones. Between 2% and 10% of all flights create around 80% of the contrails, so researchers have started developing predictive models that would allow airlines to identify and avoid contrail regions similarly to how they plan to avoid turbulence. The cost is predicted to be $0.5/ ton of CO2 equivalent. Furthermore, only minor adjustments to the routes of a small fraction of airplane flights is required, making predictive models highly attractive and cost effective. 

Some Challenges

While biofuels have great potential, they come with their own set of challenges. First is the issue of land use and its effects on agriculture. Producing three billion gallons of sustainable aviation fuel would require between 8 and 11 million acres of corn or 35 and 50 million acres of soybeans, depending on crop yields. This could impact food production and cost. Shifting to corn or soybean based fuels has also been found to produce significant adverse emissions impacts. Lastly, it’s unclear whether sustainable fuels can meet the world’s growing demand for aerial transportation.   

While hydrogen is attractive, it has lower energy density than fossil fuels, meaning that a higher onboard fuel storage volume is needed to cover the same distance as current fossil fuel-powered aircrafts. In addition, H2-powered large passenger planes would require significant changes to aircraft design, making it less cost effective in the short term when RD&D costs are considered (development of fuel cell technology and liquid hydrogen tanks, aircraft research, hydrogen infrastructure, fleet output, etc). Industry experts anticipate that it will take 10 to 15 years to make these important advancements. 

Lastly, contrail prediction models rely on a variety of input data, including flight trajectories, aircraft and engine parameters, fuel characteristics, and weather data. However, the availability and accuracy of some of these data inputs is still a challenge, as no standardization exists.

UC Berkeley chemistry professor Dr. Omar Yaghi recently led a study which has the potential to be revolutionary in reducing the quantity of carbon dioxide present in the atmosphere. “Covalent organic framework number 999,” or COF 999, is a yellow, powder-like material that has billions of tiny holes. Inside of these holes, researchers in Dr. Yaghi’s lab have installed molecular units that can seek out carbon dioxide, enabling the substance to suck in and capture the carbon dioxide. COF 999 has a huge capacity for absorbing emissions; half a pound of the powder can absorb as much carbon dioxide as a tree captures in a year.

The carbon dioxide problem

The quantity of carbon dioxide in the atmosphere has reached an all-time high, with a global average in 2023 of 419.3 parts per million. This immense amount of carbon dioxide in the atmosphere comes from a number of human sources, the most common of which is the burning of fossil fuels such as coal, oil, and natural gas for energy. Carbon dioxide is the most abundant greenhouse gas in the atmosphere, and contributes significantly to global warming and other environmental issues, including ocean acidification.

Applying COF 999 

In an interview with Forbes, Dr. Yaghi described the way he sees COF 999 being implemented as a solution. The powder can be made into pellets or a coating, and then integrated into facilities where flue gas –the gas that is released from industrial processes –is released. “This flue gas would pass through the material and because it just plucks out CO2, it cleans CO2 from that flue before it reaches the atmosphere.” According to the San Francisco Standard, Dr. Yaghi says that the powder “requires no energy, shows no signs of degradation even after 100 uses, and is made from inexpensive, commercially available materials.”  Another benefit is that the material only needs to be heated to 50 or 60 degrees Celsius, rather than to 120 like many other traditional materials necessary for carbon capture.

In order to see significant change in the atmosphere’s carbon dioxide concentration, we will need to couple preventing carbon dioxide emissions with direct air capture, which COF 999 can also do. According to Zihui Zhou, a UC Berkeley graduate student who worked in Dr. Yaghi’s lab says, “Currently, the CO2 concentration in the atmosphere is more than 420 ppm, but that will increase to maybe 500 or 550 before we fully develop and employ flue gas capture. So if we want to decrease the concentration and go back to maybe 400 or 300 ppm, we have to use direct air capture.” It will take time, however, for scientists to be able to use COF 999 effectively. This is because the powder has not been tested in real-life scenarios, and therefore the costs and risks from the powder are largely unknown; for example, the powder might restrict air flow through filters when applied, reducing the practicality of the powder.

Methane (CH4) (the primary component of “natural gas”) is the second most important greenhouse gas after carbon dioxide.

Around 60% of global methane emissions come from human activities in three main sectors: energy production (oil, gas, and coal), agriculture (livestock and rice), and waste (landfill and waste water). Energy production accounts for about 35% of anthropogenic methane emissions, agriculture accounts for about 40%, and waste accounts for about 20%. 

Why is methane leakage prevention important?

Methane leaks from fossil fuel production, landfills, and livestock include emissions that are described as “super emitter events,” which have devastating ecological effects. While methane has a much shorter atmospheric lifetime than CO2 (around 12 years compared with one hundred years or more for CO2), it is a significantly more potent greenhouse gas, trapping eighty times more heat than CO2 over a 20 year period, which exacerbates the effects of climate change on our planet. Methane also negatively affects air quality because it is an ingredient in the formation of ground level (tropospheric) ozone, a dangerous air pollutant. Thus, monitoring methane leaks and formulating preventative methods is crucial to preserving the health of both the planet and all those who occupy it.

A growing need for methane prevention efforts: how satellites can help us curb methane leaks 

The United Nations Environmental Program (UNEP) has undertaken many initiatives to mitigate methane leaks. In October 2021, UNEP launched the International Methane Emissions Observatory (IMEO), which catalogs emissions for the three largest methane-emitting sectors in a public database, providing governments and companies access to empirically verified methane emissions. This data can be used to build efficient policies to address large methane leakages. 

In 2022, the UNEP launched the International Methane Alert and Response System, or MARS through its IMEO program, the first ever satellite-based detection system that notifies governments of major methane leaks from their fossil fuel infrastructure. IMEO breaks down satellite detection in four essential steps:  

1. IMEO uses global mapping satellites to identify very large methane plumes.
2. The emissions information is shared with governments and companies. Important information includes detailed information on their location, size, potential sources, and operators of the relevant facilities.
3. It is up to notified stakeholders to determine how best to respond to the notified emissions.
4. IMEO continues to track methane leakages around the world, repeating the process when large methane plumes are detected. Data and analyses are made public 45 to 75 days post detection on the MARS data portal.

There is still more work to be done 

While developing satellite technology has helped, Dr. Aganaba argues for greater collaboration between different levels of government and greater transparency. While many governments and companies have agreed to methane emission reduction pledges, they are rarely legally binding.  

Dr. Aganaba offers the following challenges and solutions. First, we need greater momentum at the federal level to get local and state actors to participate in satellite-based climate data collection. Second, there needs to be a standardization of data monitoring, collection, interpretation, and distribution in order for information to be verified and shared effectively, as this will enable better enforcement methods and compliance. Third, once what Dr. Aganaba refers to as a “national geospatial data infrastructure” is established, the international community must amend the space charters that dictate the current international geospatial data infrastructure. Dr. Aganaba stresses that this legal framework is crucial both to safeguard the environmental integrity of outer space and ensure that the mistakes made on earth are not repeated, both in terms of environmental exploitation and power sharing between developed and developing nations.  

Satellite data is not a panacea. Satellites can sometimes mistake clouds or other natural phenomena for methane leaks. These readings are not always reliable as they can be obstructed by clouds, dense forests, or snow, and do not provide information about how much methane is being leaked in a specific location. They do, however, provide a great deal of useful data and much greater transparency.  

Who is Dr. Timiebi Aganaba?

While wind energy is renewable and non-polluting, the wind turbines themselves can create pollution problems. Now, scientists are creating wind turbines that can be made with less energy, but also create less waste because they can be recycled. This, of course, reduces impacts on the waste stream and provides a sustainable alternative to current wind turbines that are often extremely hard to recycle. Moreover, the new material requires less energy to create and mold into the desired output, subsequently reducing associated greenhouse gas emissions.

Making Wind Turbines with Recyclable Resin

Not surprisingly, even renewable energy resources also have environmental costs. For instance, when the life of a wind turbine ends (after about 20 years), it ends up in landfills. Moreover, as more wind farms are built and older turbines are taken out of usage, the waste burden is significant. Most resins also used in wind turbines require many nonrenewable resources and a lot of energy to produce. In addition, they do not easily degrade.

This is why researchers at the National Renewable Energy Laboratory (NREL) started developing turbines from recyclable resin. They call the resin PECAN, and it is created with “bio-derivable resources” like sugars as opposed to the type of resin that has traditionally been used, which is not bio-derived and extremely hard to upcycle. Specifically, when the wind blades are unusable they are shredded to be used as “concrete filling”, which never biodegrades, while turbines made of recyclable resin can chemically break down within 6 hours.

Benefits of Recyclable Resin 

Not only can PECAN withstand harsh weather, but it does not deform over time. Additionally, once the resin undergoes a chemical process called “methanolysis” it only takes 6 hours for the original carbon and glass to be recovered to be recycled. Moreover, the catalyst to harden the resin is also recovered and this means that it is possible for it to be used again (creating a circular waste stream). Moreover, PECAN produces “40% less greenhouse gas emissions and 30% less energy to make”.

Challenges of Implementation 

There is a general lack of awareness of solutions like PECAN which strive to make our waste stream more circular, and without that awareness, it would not be able to make the large positive impact that it is capable of making. This is also one of the reasons why right now, wind turbines made out of recyclable resin proves to be more expensive, as there is not enough of a demand for it yet.

Ryan Clarke believes that creating wind turbines from naturally occurring resources like sugars can be extremely helpful in waste reduction. Additionally, he emphasizes that larger deployment of this technology and increased awareness can lead to major cost savings in the long run.

Wheat varieties that are resilient to climate change are sometimes referred to as "chaos wheat." An initiative of King Arthur Baking Company–an emerging leader in the creation of chaos wheat–and Washington State University's Breadlab is aiming to create wheat blends, such as King Arthur's Regeneratively-Grown Climate Blend Flour, composed of unique wheat varieties bred for resilience against the unpredictable effects of climate change, including fluctuating temperatures and varying water levels. These wheat varieties are cultivated using regenerative agricultural practices that enhance soil health and biodiversity.

Chaos Wheat as Climate Solution

By focusing on breeding wheat that can withstand extreme weather conditions, the initiative seeks to ensure consistent crop yields despite environmental unpredictability. Additionally, the use of regenerative agriculture practices contributes to carbon sequestration, improved soil health, and increased biodiversity, all of which play a role in mitigating climate change. 

To create the special, “Climate Blend” flour out of chaos wheat, researchers use practices like “cover cropping and crop rotations, minimizing inputs, no/limited tillage, and affordability and accessibility of crops.” The chaos wheat collaboration with Washington State University’s Breadlab, aims to increase biodiversity, promote carbon sequestration by improving soil health, and build resilient farm ecosystems as a whole.

In the late 1800s, white bread was extremely popular due to its low cost of production at enormous scale. However, this quickly became detrimental to the environment because it led to monoculture, which reduces genetic biodiversity.  In fact, large scale bread production “emits more greenhouse gases than Russia, Brazil, and Germany combined”.

Benefits of Chaos Wheat

Chaos wheat increases genetic diversity and reduces risk of diseases and increases “resistance to drought, pests, and volatile weather, while requiring less water, fertilizer and agrochemical.” Part of the potential advantage of chaos wheat is the plants’ improved ability to deal with “‘ chaotic events.’” Currently, however, it is more expensive in comparison to standard whole wheat, “$2.98, compared with $1.12”.

The inspiration for this blend came from ancient strategies that farmers employed, for example a “mix of different species and varieties known as maslins” which are “plants [that] compete less with one another for soil resources and are diverse”. Essentially, if “they can offer 2 to 3 percent higher yields, they will be our greatest asset to increasing yields and crop resilience.”

Challenges of Implementation

Potential critiques or drawbacks of this solution include the challenges associated with transitioning farmers to regenerative practices, which may require significant changes in traditional farming methods and could involve initial financial investments. Moreover, as regenerative agriculture is currently unregulated and lacks standardized certification, defining and implementing consistent practices can be complex. Ensuring that these new wheat varieties are economically viable for farmers and acceptable to consumers in terms of taste and baking quality also presents potential challenges

There is also a tension between large scale efforts, including the King Arthur Baking Company initiative, and more local initiatives that might be “developing more sustainable and climate-resilient products” and which “keep our dollars in the local food economy” but “invest[s] in a more sustainable and resilient food economy”. This is often a difficult tradeoff.

Robin Morgan believes that chaos wheat is a  game-changer in agriculture and in the face of climate change as it reduces wheat’s vulnerability to extreme weather conditions. This means that the crops can grow in more locations and with reduced soil disruption. Moreover, he emphasizes that it increases health benefits by providing more fiber to consumers.

The US electric vehicle (EV) market is expected to reach a revenue of $95.9 billion this year, with a projected annual growth rate of 12.61% over the course of the next four years. By 2035, California and twelve other states are planning to achieve 100% zero-emission new vehicle sales, calling upon local governments to assist in the EV transition to ensure equitable access to this new technology. For homeowners who have the ability to power up in their own garage, making the transition to EVs is relatively easy; however, for renters and those living in larger metropolitan areas, access to charging infrastructure remains a significant challenge. Although EV adoption is on the rise, urban areas are under constraint as they do not have sufficient charging infrastructure to keep up with heightening demand. High building density, limited capacity of the electricity grid, and insufficient funding and staffing are posing challenges for city governments across the country. Brooklyn-based startup, It’s Electric, is working on one possible solution to this problem through the installation of curbside charging, powered from buildings on the adjacent property rather than directly from the utility grid. 

Building EV Charging Accessibility

Curbside charging works by minimizing the distance consumers need to travel to fuel their EV, thereby increasing accessibility of charging infrastructure. Many dense-urban areas have been referred to as “charging deserts,” due to their lack of accessible EV charging infrastructure, making the transition in these areas particularly challenging. Instead of the mainstream route in which charging infrastructure is developed through utility connections (which can be a 12 to 18 month process), startups like It’s Electric partner with property owners, acquire the relevant permits, and install and maintain a charger powered by the building’s electrical supply. Property owners can thus use untapped electricity supplies, allowing for installation without extensive infrastructure development or direct connections, providing property owners with passive revenue. Instead of working directly with electric utilities to install their chargers, It’s Electric partners with municipalities and building owners directly. Further, the parking space will be maintained by the city, so the property owner doesn’t need to worry about managing and maintaining the parking spot.

Benefits of Curbside Charging

Curbside charging provides immense promise for city governments in transitioning towards more equitable access of EV charging infrastructure. For lower-income communities – particularly those without access to private driveways, garages, or who reside in multifamily housing – publicly accessible EV charging can help reduce barriers to participation in the ongoing shift to electric vehicles. As curbside charging is still in the beginning stages of development, policymakers can incorporate community members in decision-making. Thus, EV charging can be largely community-driven, incorporating opinions from local residents to make the transition fit the needs of the community. In dense urban areas, curbside charging can assist in reducing pollution and GHG emissions, particularly in high-emissions neighborhoods. Other strategies to keep in mind include providing discounts and cost reduction measures for lower income drivers as well as strategies like car share, mobility hubs, and colocation with other transportation services to improve accessibility. 

Drawbacks

Without addressing lower-income communities and those living in rental properties, EV charging can exacerbate current socioeconomic disparities and push marginalized communities out of the growing market. Thus, in tackling this transition, focus must be placed on targeted communities that lack the necessary resources to successfully adopt EVs. It’s Electric has noted that there is more demand than they can meet right now, which represents the urgent call for this transition to occur. It’s Electric is currently integrating Level 2 chargers into city infrastructure, rather than the faster direct current (DC) chargers that can power one’s vehicle in 15-30 minutes. Because DC chargers take up significant amounts of space, require more infrastructure to develop, and utilize more electricity, it is not yet feasible to implement these in urban areas. Unfortunately, that leads to slower charging times and potentially limits an area’s charging capacity. Another drawback of curbside charging in large cities can be attributed to limited sidewalk space and thus heightened demand for the few available units. Amidst these potential challenges, It’s Electric has successfully resolved problems such as grid capacity and design by providing affordable, easy to install, and compact charging stations. By working collectively with policymakers, urban planners, transportation specialists, and community members, companies like It’s Electric have begun to make curbside charging a reality.

In cold winter months, many people have to rely on fossil gas to heat their homes and power cookstoves. Yet all-electric appliances, including heat pumps to heat homes, are quickly becoming a cheaper alternative over the long term, though they often entail higher upfront costs compared to gas appliances.

In Chicago, the switch from natural gas to electricity is moving forward, but it is also revealing unintended challenges for low-income residents that are applicable to the broader energy transition. In the historic city core, many older buildings lack weatherproofing and insulation against extreme winter cold. Climate and health impacts, and the high price of burning fossil fuels for heat, provide ample reasons to switch from fossil gas to electricity. But as high-income people are doing so, they leave some of the most vulnerable people behind. As a result, Chicago is now pioneering an effort to support lower-income residents making the transition to all-electric heating.

What are the Climate and Health Impacts of Gas Heating

Gas heating is powered by natural gas, which is mainly composed of methane, a potent greenhouse gas. From a climate perspective, methane’s ability to trap heat in the atmosphere is 84 times greater over a 20-year period than carbon dioxide, making it the second most important contributor to climate change. And, because it lasts for 10 to 15 years in the atmosphere, while CO2 lasts 100 years or more, reducing methane emissions will rid the atmosphere of a potent greenhouse gas much more quickly. One-third of human-caused methane emissions come from the energy sector, and a large portion of methane use comes from waste such as leaks and venting. From a health perspective, a byproduct of natural gas called nitrogen dioxide is known to reduce lung function, and cooking with natural gas stoves has been linked to childhood asthma. Natural gas’s climate impacts and more immediate respiratory impacts may pose a health risk in homes that can be reduced by a switch over to electric heating.

Why are People Flipping the Switch?

As the price of natural gas rises, electricity may become a cheaper option for many Americans. The current structure of utility companies contributes to the high costs that ratepayers are facing. One concept found in utilities is the rate base, which refers to the amount of money and resources a utility company uses to produce and deliver electricity, water, or gas services. Regulators decide whether or not the investments that companies make are considered “prudent” and these expenses are added up to form the rate base, upon which the utilities are allowed to earn a rate so they can profit. This structure means that the costs of large capital investments are paid for by an increase in a rider on ratepayers’ bills, passing the cost burden onto customers.

For electricity here in California, the threat of wildfires caused by powerlines and the high cost of building transmission means that ratepayers face high electricity rates, especially compared to gas. Meanwhile in Chicago, one main reason many residents are switching to electric heating is because of recent price hikes from the major gas utilities supplier. According to Sarah Moskowitz, Executive Director at the Citizens Utility Board (CUB) of Illinois, a retrofitting effort by the gas utility in Chicago means that customers may be facing unusually high bill riders over fifty dollars, a fixed cost applied even before any gas is used. There is a strong economic incentive in Chicago driving people who can afford to switch over their appliances to electric.

But what about those who cannot afford to move away from gas heating? According to Moskowitz, primarily low-income Black and brown communities face some of the biggest impacts of soaring natural gas prices. In addition, the rate base system which allows costs to be passed onto consumers can further exacerbate the problem. As people with the means to switch away from gas do so, this lowers the number of gas customers across which the utility company can divide its costs. This means that the people who can least afford it will bear a greater portion of the costs, a problem sometimes known as the utility debt spiral. But new legislation and funding are attempting to build a path out.

Making Heat Accessible & Affordable

In an effort to set Illinois on the path to carbon-free and renewable energy, a law that contains interesting pathways for utility justice was passed in 2021. The Climate and Equitable Jobs Act (CJA) sets ambitious clean energy goals, but does so in a way that prioritizes equity. The bill provides finance for lower-income residents and provides support for energy efficiency and renewable energy workforce development. According to Moskowitz, one particularly climate-justice-focused program is the equitable energy upgrade program, a form of utility bill financing. The law requires major Illinois utilities to file multi-year rate plans, and from these, 40% of the benefits must go toward low-income communities. Exactly how the benefit process will work is being determined. The CJA provides a framework that can be adapted for many other regions. As Chicago takes on the challenge of moving towards renewable electricity in a city with older infrastructure and high heat demand, the city may serve as a case study that other cities can look to when planning for clean energy alongside justice and equity.

Who is Sarah Moskowitz?

Sarah Moskowitz is the Executive Director at the Citizens Utility Board (CUB) of Illinois, which has represented the interests of utility ratepayers since the 1970s. CUB works to get more consumer-friendly laws passed, runs a utility question & complaint hotline, and organizes consumer education and outreach programs.

Pumped storage hydropower, also known as water batteries, are often used as a means to store excess renewable energy. For example, solar and wind may generate more energy than is needed during certain times of the day and less than what is needed at other times.  As a result, water batteries are extremely useful as a way to store and release energy during peak demand periods or when renewable sources are unavailable (i.e, when the sun is down). This form of energy storage is used in many places across the country, and across the world, including Tennessee, Kentucky, and San Diego. 

Current and Future Use of Pumped Storage Hydropower

In San Diego County, a proposed pumped storage hydropower project would connect a lake to large underground pipes which will “connect this lake to a new reservoir… 1100 feet higher in elevation” so that “when the sun is high in the sky, California’s abundant solar power will pump water into that upper reservoir.” When the sun is down, the water would be released to the lower lake, generating around ”500 megawatts of electricity for up to eight hours” which is “enough to power 130,000 typical homes.”

At Tennessee’s Raccoon Mountain, TVA stores the excess energy as gravitational potential energy and produces about “1700 megawatts of electricity” when in demand during the day. It takes extremely long for these projects to get approved because the investment is “more than 2 billion dollars for a large plant”.  The project consists of three components: a lower reservoir “bounded by a 62 meter high dam” and “replenished as need to make up for evaporation;” an underground powerhouse which is “a 137-meter-long cavern” housing “three pump turbines;” and an upper reservoir which “would be some 600 meters across and bounded by a 53 meter high dam.”

All currently operating pumped storage hydropower projects in the U.S. are “open-loop” facilities, meaning the lower reservoir is a natural water source such as a lake or river. This is the case with the San Diego and Racoon Mountain projects. In contrast, “closed-loop” pumped storage is built offstream and operates independently of natural waterways. For example, at a proposed pumped storage facility in Kentucky, an old coal mine is being repurposed to be used as a water battery. This land has “hosted mining for at least 70 years” and this “project would deliver up to 287 megawatts of power for up to 8 hours, giving it more storage in the tank than the biggest lithium battery plants built thus far”. Closed-loop pumped storage is generally viewed more favorably than open-loop systems by many environmental groups, tribes, and modern hydropower developers because it avoids continuous interaction with natural waterways and can reduce impacts on fish and river ecosystems.

Benefits of Water Batteries

Water batteries are incredibly useful for long-duration energy storage and can help balance fluctuations in renewable energy sources like solar and wind by providing power during peak demand periods. For instance, in San Diego, “the San Vincente project would store roughly as much electricity as batteries in 50,000 of Tesla’s long range Model 3 cars” and does not need materials like cobalt and lithium which are not only hard to find but create a lot of e-waste (and side effects with mining). Moreover, these projects fuel the economy and can create an abundance of construction jobs.

Challenges of Implementation

Pumped hydropower requires a lot of land, and flooding impacts habitat, and in some cases areas protected by indigenous tribes. The land and local ecosystem impacts can be very substantial. Moreover, water batteries require significant elevation difference between reservoirs to be effective so there are often geographic limitations to deployment. It can be extremely challenging to find places to build water batteries because they require specific topography as well as impacting the surrounding landscape. On top of this, these “facilities are expensive to build and take years to develop”. However, once they are in full structural integrity, they “store energy for far longer than lithium-ion batteries… and they last for many decades with minimal deterioration.”

Erik Steimle emphasizes that pumped hydropower/water batteries are a great way to generate energy in a more sustainable manner, however, he acknowledges that there are some downfalls of it. For example, pumped hydropower/water batteries must undergo extensive regulatory practices involving federal agencies that other types of energy storage and renewables do not, posing a barrier to widespread accessibility. Another benefit is the durability of this equipment, which can be useful for hundreds of years.

Public universities like UC Berkeley have played a major role in developing climate solutions, from innovation in labs to policy initiatives. In order to create positive change in the climate space, science requires funding, which universities can provide. Further, universities, of course, educate, train, and interact firsthand with people who, in the future, will work in the climate space, putting them in an essential position in terms of climate education. 

How UC Berkeley is Making a Difference

UC Berkeley specifically has made several important contributions across all aspects of climate science, climate education, and climate solutions.  Some examples include Omar Yaghi’s lab and its discovery of a potentially revolutionary approach to carbon capture with COF-999, as well as the EcoBlock project in Fruitvale, Oakland, where Berkeley is helping to retrofit “residential homes to improve resilience, sustainability, and quality of life for all community members.” Further, Berkeley has established over fifty undergraduate courses related to climate issues. These courses and initiatives largely attract students because younger generations have significant firsthand experiences with climate change, including wildfires, heat waves, flooding, and air pollution. 

Why Climate Action from Public Universities is More Important Now than Ever Before

With the current uncertainty of continued federal government funding and support, some climate work may face limitations. Nonetheless, university focus on climate change is increasingly necessary to ensure that future generations of citizens are fully informed and well able to participate in a climate change constrained future. As explained by Bruce Riordan, director of the Berkeley Climate Change Network, “these problems require multiple disciplines,” and Berkeley is well positioned across multiple fields of study, research, and action,  recognizing that climate change requires integration of business, policy, and research and beyond.  

About Our Guest

Bruce Riordan is the Director of the Berkeley Climate Change Network, a collaboration of 300+ faculty and staff at UC Berkeley and the Lawrence Berkeley Climate National Laboratory working in the climate change space. The BCCN seeks to accelerate Berkeley’s research, education and service to meet the urgency of the climate crisis by connecting researchers for interdisciplinary projects, helping to raise money for climate research, and building connections between Berkeley academics and off-campus climate leaders across industries.

Most current energy technologies burn fossil fuels and emit carbon dioxide, which contributes to global warming.  Adopting low and zero-carbon technologies is one way to reduce emissions, but barriers such as high upfront and maintenance costs have impeded the adoption of these technologies.  Energy as a Service (EaaS) is a pay-for-performance model in which customers benefit from sustainable-energy solutions without having to pay for energy efficiency upgrades or own the equipment. Under these arrangements, the EaaS provider provides the customer with an energy service, such as lighting, cooling, or heating, in exchange for a recurring fee.  There are parallels in other industries like the software industry, where a key business function or an asset is outsourced to a third party who then takes over the operation of that asset. EaaS providers typically handle the installation, maintenance, and operation of energy systems. By leveraging advanced technologies and data analytics, EaaS aims to enhance energy efficiency, reduce costs, and support sustainability goals, helping businesses improve their energy performance without significant upfront investment.

Benefits of the Energy-as-a-Service Model

By shifting from a traditional ownership model to a service-based approach, customers can avoid the high initial costs associated with purchasing and installing energy infrastructure. Instead, they pay for the energy services provided, often through a subscription or pay-as-you-go arrangement.  EaaS providers typically take on the responsibility for the installation, maintenance, and operation of the energy systems, allowing customers to focus on their core business activities without worrying about energy management. 

EaaS can also support sustainability goals by facilitating the adoption of renewable energy sources and other low-carbon technologies. Providers can tailor energy solutions to meet specific environmental objectives, helping businesses reduce their carbon footprint and comply with regulatory requirements. Furthermore, EaaS models often incorporate advanced technologies and data analytics, enabling more information about and control over energy consumption, which results in better demand management and reduced energy waste.

The EaaS model also offers flexibility and scalability. As energy needs change over time, customers can easily adjust their energy services without the need for significant reinvestment or restructuring. This adaptability is particularly valuable in a rapidly evolving energy landscape, with frequent technological advancements and policy changes.

Barriers to Adoption of the Energy-as-a-Service Model

Our guest notes that energy efficiency and sustainable energy projects have been undervalued and not prioritized in the past. While many companies see energy efficiency and sustainable energy projects as the right thing to do, there are often other items that rise to the top of the to-do list. In addition, businesses and individuals may be unfamiliar with the EaaS concept, leading to hesitation in adopting this model.  Projects can take significant time to plan and install, which can also serve as a barrier.  To date, the EaaS model has been geared towards primarily larger business and commercial customers that are consuming a higher amount of energy, rather than residences and smaller businesses.   However, utility companies and governments sometimes offer energy audits and incentives for adopting energy-efficient equipment, and new companies may eventually serve this market.

The increase in climate-related disasters, such as floods, wildfires, and heat waves, has created serious financial burdens on households across the country. Since 1980, the world has seen a fivefold increase in the number of billion-dollar natural disasters. 2018 to 2022 alone saw an estimated $617 billion in damages from climate and weather related events. Beyond the public health and safety concerns, these disasters have hit Americans in the pocketbook. An estimated 13% have reported facing severe economic hardship following such disasters, with this number projected to rise as climate extremes become more frequent. For particularly vulnerable households, high financial costs from disasters can further exacerbate existing inequities. In order to adapt to a changing world of more frequent climate catastrophes, policy makers will need to develop solutions to assist populations in disaster recovery. 

Solutions to climate-related financial disaster

The impacts of climate-related disasters are numerous. In addition to harming businesses and infrastructure, extreme weather events can lead to worker displacement, job loss, and migration. Catastrophic climate events, known as climate hazards, create financial strain on households from damage done to one’s property. Many households may not have the immediate resources or savings needed to repair the damage, leading to long-term displacement and financial instability. Healthcare costs, transportation expenditures, and inability to access proper insurance coverage are other burdens many individuals face following a natural disaster.

Low-income communities will face the brunt of climate change impacts. By understanding the historical inequities that have pushed marginalized communities into regions particularly vulnerable to climate change, policy makers can create more equitable outcomes. Many officials are now encouraging increased access to education, “democratized” climate decision making, and new ways to engage and empower people to take a stance in decisions about the climate. 

The US Department of the Treasury further suggests that households consider utilizing government incentives to adopt climate-resilient property modifications, such as tax credits and rebates for energy-efficient home improvements. Policymakers further plan to support financial well-being by assisting households in financial resiliency efforts with programs through the Federal Emergency Management Agency (FEMA) and U.S. Small Business Administration (SBA).

Advantages of improving financial stability following a climate disaster

Initiatives designed to address vulnerable communities affected by climate disasters can assist in adaptation towards climate extremes. Having access to resources, whether political or social, is key to providing impacted communities with the support they need to adapt to a changing environment. With increased educational awareness and government assistance, households facing financial distress and instability following a climate-related event will have the support they need to recover.

Setbacks to achieving financial stability 

In order for these goals to be realized, policy makers will need to overcome significant challenges. For example, many households across the country face underinsurance, as climate extremes become more common and push insurers to raise rates or pull out of the insurance market altogether. As a result, vulnerable regions may be left without the proper resources to recover. A recent report found that policies for 39 million properties (about a quarter of all homes in the US) are under-priced for the climate risk needed to insure those properties. Without insurance coverage, homeowners are unable to fix damaged property.

Furthermore, the most severe effects of climate change disproportionately affect socially vulnerable populations. Less than 60% of single-family homeowners living in areas where mandatory flood insurance is required actually have the necessary insurance. As such, policy makers need to pay more attention to those communities most vulnerable to climate change in order to ensure they have access to the insurance needed to recover from a disaster and achieve financial stability following a climate-related event.

Dr. Andrew Rumbach, Senior Fellow in the Metropolitan Housing and Communities Policy Center at the Urban Institute, studies household and community risk to natural hazards and climate change. Dr. Rumbach is involved in the policy implementation and research of numerous federal and state-declared disaster events and is on the forefront of addressing disaster vulnerability and environmental risk.

Ever wonder where your used coffee grounds go after they’ve been completed? Probably not. But at South Dakota State University, researchers are turning them into something entirely unexpected: plastic. Not just any plastic, but a biodegradable alternative to oil and gas-based plastics that dominate the industry today. This innovative approach not only tackles the issue

of food and other biomass waste but also addresses the plastic industry’s reliance on fossil fuels and the rampant plastic pollution that harms both planetary and human health.

The Pervasiveness of Plastic

The vast majority of plastics are currently made from natural gas and crude oil, types of fossil fuel. As of 2019, this production process was responsible for 3.4 percent of the world’s total greenhouse gas emissions. Moreover, humanity produces over 300 million tons of plastic each year, resulting in widespread plastic pollution with adverse effects on both the environment and human health. Despite masquerading as a solution to excessive plastic waste, traditional plastic recycling is often ineffective due to contamination and industry deception. Thus, most plastic waste is diverted to landfills. Fossil fuel-based plastics take hundreds to thousands of years to decompose, and when they finally do, they release microplastics into the environment, which can infiltrate human bodies. 

Recognizing the need for a solution to this plastic crisis, Dr. Srinivas Janaswamy, the lead researcher, initially experimented with making biodegradable packaging using various agricultural byproducts, such as avocado peels, corn, oats, and wheat stalks. His focus has since shifted to spent coffee grounds, which contain lignocellulosic fibers — natural plant polymers essential for creating biodegradable plastics. The process of transforming coffee grounds into biodegradable films is quite intensive and involves drying, bleaching, and extracting the plant fibers from the coffee grounds. The resulting clear solution is then dried to form a strong, plastic-like film that can be used as a sustainable alternative to traditional plastic packaging.

A Second Life for Coffee Grounds

One of the significant advantages of this solution is its potential to reduce greenhouse gas emissions from fossil-fuel-based plastic production and minimize plastic pollution. But on top of that, it provides a sustainable method of reusing otherwise wasted coffee grounds. Every morning, millions of people worldwide begin their day with a cup of coffee, a ritual shared by over 60% of Americans. Widespread enthusiasm for this caffeinated beverage has propelled it to become the second most traded commodity globally by volume, just behind oil. As a result, coffee shops are ubiquitous, generating an enormous amount of spent coffee grounds — approximately 8 million tons annually, much of which ends up in landfills. 

When left to waste away in landfills, coffee grounds can release methane, a potent greenhouse gas that exacerbates climate change. Meanwhile, biodegradable films derived from coffee grounds can decompose in soil within just 45 days, a stark contrast to traditional plastics. Because of their rapid biodegradation and abundance, spent coffee grounds provide an attractive resource for bioplastic packaging innovation.

Market Barriers in a Plastic-Dependent World

Despite its promising potential, the coffee ground-based film still faces challenges. The film has immense tensile strength — meaning it can withstand a great deal of stress before fracturing — but is less flexible than traditional plastic, which may ultimately limit its applications. Additionally, the production costs currently exceed those of fossil fuel alternatives. Nonetheless, Janaswamy is optimistic about its market potential, remaining confident that costs will decrease as technology evolves.

As consumers become increasingly aware of the detrimental environmental and human health impacts of traditional plastics, there is a growing demand for eco-friendly alternatives. Even if these biodegradable plastics do come at a higher price, consumers may be willing to pay extra for the sustainability benefits they offer. Therefore, coffee ground-based packaging film presents an environmentally conscious solution without compromising the desired convenience of plastic packaging.

About Our Guest

Dr. Srinivas Janaswamy, an associate professor at South Dakota State University's Department of Dairy and Food Science, continues to lead research on developing sustainable, biodegradable packaging materials as alternatives to traditional plastics. His work embodies the shift towards a more sustainable future, one in which waste is transformed into valuable resources and where our daily habits — like brewing a cup of coffee — can contribute to a cleaner planet.

The Waverley Street Foundation, founded by Laurene Powell Jobs in 2016, aims to attack climate related issues through funding community-led programs, leading to community action against climate change. The Waverley Street Foundation specifically funds programs related to renewable energy and regenerative agriculture, as these sectors have an immense impact on the environment and vulnerable communities. The Foundation’s approach to achieving climate-related goals is unique, as their solutions revolve around investing in prominent community institutions in order to benefit the entire community, showing people that we all benefit from a healthy planet.

Regenerative Agriculture as a Climate Solution

Regenerative agriculture is the practice of using farming and agricultural techniques to help reverse climate change, including some techniques that date back to Native American cropping systems and the way in which they interact with the soil. According to the California Department of Food and Agriculture, the goals of the practice include helping to “mitigate climate change, improve soil health, restore biodiversity, enhance ecosystems, and contribute to human health.” By focusing on the larger community impacts of sustainable farming practices, the Waverley Street Foundation promotes a close connection between people and their food systems. As an example,  the Foundation established agreements with local school districts to support fresh and nutritious lunches, bringing  local regenerative farmers into the supply chain, thereby improving farmers’ economics, and allowing them to decide to continue planting regenerative crops. 

Other Community-Based Climate Initiatives

The Waverley Street Foundation is also currently working on converting health clinics from being run on diesel fuel to solar in India. This not only reduces pollution and carbon emissions, but can also help make healthcare more affordable for residents, while providing new local jobs installing, fixing, and financing the panels. In order to evade the most devastating climate change impacts, emissions need to be reduced by almost half by 2030 and reach net-zero by 2050. 

The ultimate goal of the Waverley Street Foundation is to approach climate change with a new outlook: “Cultivating Health, Justice and Joy,”  emphasizing the role that climate change has in harming vulnerable communities’ everyday lives rather than solely focusing on technical solutions. Jared Blumenfeld, the president of the Waverley Street Foundation, argues that “unless we can make the case to them, that climate action is going to support and make their communities stronger, I don't think we win many of the other arguments.”

About Our Guest

Jared Blumenfeld is the former Secretary of CalEPA and current President of Waverley Street Foundation, the climate philanthropy funded by Laurene Powell Jobs. Blumenfeld also served as Director of San Francisco’s Department of Environment.

People with disabilities are disproportionately affected by climate change; however, they have been traditionally excluded from conversations about national plans and responses to climate change. Including the disabled community in decision making is key to addressing potential harms and designing effective, inclusive solutions. 

Disabled Community Disproportionately Affected

Many studies provide empirical evidence that climate change poses a particularly great risk for the disabled community. A study in Australia documented that between 2001 and 2018,  89% of heat wave fatalities were people with some type of disability, and actually many had multiple disabilities both physical and mental. Additionally, after Hurricane Harvey in Harris County, Texas in 2017, people with disabilities were disproportionately affected and exposed to harms. Areas flooded by Hurricane Harvey were overrepresented by disabled populations. The highest proportion of people living in public housing being exposed to environmental hazards were people with disabilities. 

While people with disabilities are particularly vulnerable to natural disasters, they have often been excluded from decision-making surrounding climate change, including in  drafting national plans and climate responses. 

Inclusivity and Accessibility In Practice

Engaging people with disabilities in developing, designing and implementing climate resilient solutions can help protect their livelihoods and autonomy. Meaningful participation can look different in many ways including conducting research to have more data on how people with disabilities are affected and specific ways to help. As well, to develop new technologies and innovations that assist people with disabilities in climate emergencies like early warning systems, communication, and adaptive infrastructure. Spaces can be more inclusive and accessible to people with disabilities. More research is needed on infrastructure design that both reduces emissions and simultaneously will not put disabled people at more risk in climate emergencies, for example, adding ramps and automatic door openers, widening doorways, and having accessible bathrooms. It is also important to host public events in accessible locations to ensure that people with disabilities feel welcomed and valued. Methods of communication should also be accessible like using captions in videos, adding text descriptions and making online materials that work with screen readers so that low vision individuals can also access them. 

Disability-Inclusive Climate Solutions

In addition to educating the community about the importance of disability-inclusive climate solutions and for the disabled community to be educated and equipped for climate disaster risk mitigation, it is vital for the disabled community to be part of the large-scale decision making process and promote meaningful participation. By providing people with disabilities with a greater understanding of the impacts that climate change will have on their lives, then they can be more able to respond to effects of climate change and access the resources they need. Expert Dr. Michael Stein points out that everyone knows their own needs and livelihoods best; hence, it is vital to reach out to the disabled community and include them in the conversation and decision making for climate solutions that will support the disabled community who are disproportionately affected by the effects of climate change.

In 2020, nearly 90% of homes used air conditioning systems in the United States. Heating, ventilation and air conditioning (HVAC) systems are used by both homeowners and businesses alike, with their usage only expected to rise as climate change increases global temperatures. Refrigerant, a chemical compound that is capable of transitioning from liquid to gas and back again, has been an important part of indoor cooling systems since modern AC systems were invented in 1902. Its ability to cool as it vaporizes and heat up as it condenses facilitates heating and cooling. As part of both air conditioner and heat pump systems, refrigerant either helps transfer heat and humidity out of one’s home for conditioning or draws heat from outdoor air and brings it inside for heating. 

Refrigeration technology has historically relied upon gases like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) to promote cooling in appliances, due to their effectiveness at transferring heat within a refrigeration system. While effective, these gases are hazardous for the environment. HFCs have a global warming potential (GWP) that can be hundreds to thousands of times greater than that of carbon dioxide. Gaseous CFCs have a high ozone depletion potential (ODP), meaning there is less protection from the sun’s rays and greater exposure to UVB radiation, negatively impacting human and ecological health. Instead of relying upon harmful CFCs and HFCs in refrigeration technology, UC Berkeley researchers are on the cusp of developing a new alternative known as “ionocaloric” refrigeration, which utilizes salt water to provide cooling. 

How does Ionocaloric Cooling work?

Created in 1987, the Montreal Protocol regulates the production and consumption of nearly 100 human made chemicals classified as ozone depleting substances (ODS). The Montreal Protocol mandated the eventual phase-out of CFCs and HCFCs, instead turning to HFCs as a replacement. Although HFCs do not deplete ozone, they were later found to have a significant GWP, prompting a recent amendment to reduce HFC usage by 80% in the next thirty years. As HFCs are phased out, ionocaloric cooling has been proposed as an alternative for refrigerant. 

Ionocaloric cooling relies on the principle that liquids release energy, or heat, when solidified, and solids absorb energy when liquified. In an ionocaloric refrigerant system, a mixture of a liquid and salt is frozen and melted. When a current is added, ions flow and change the material from solid to liquid, which allows them to absorb heat from their surroundings. Similarly, when ions are removed, the material crystallizes into a solid, releasing heat. The mixture is easier to manage as it is never in a gas state and is unable to enter the atmosphere. Additionally, certain solvents like ethylene carbonate, which have been used to test the technology, can be carbon-negative due to their ability to be produced from CO2 supplied by carbon capture. This means that ionocaloric cooling can prevent current emissions with high GWP and ODP, while also removing emitted gases from the atmosphere. 

Promise of Ionocaloric Cooling

Ionocaloric cooling has the potential to modify current HVAC systems, which rely upon high GWP gases that act as refrigerants. By using solid and liquid components as opposed to HFCs to function, ionocaloric refrigeration prohibits these harmful gases from ever entering the atmosphere. In addition to its cooling purposes, this technology can also be used for heating. Ionocaloric technology has the potential to compete with or even exceed the efficiency of gaseous refrigerant. Currently, ionocaloric cooling technology is still being developed. If proven successful, this innovative technology could transform the current landscape of HVAC systems. 

Hurdles to Overcome

As of now, ionocaloric cooling is not fully developed. Although the material cost for the salt water is cheap, it is unclear the cost of every component needed on a larger scale. The research currently being conducted for ionocaloric cooling experimentation is heavily subsidized. As it is still under R&D, this technology’s viability on a larger-market scale will be continually determined. To facilitate a transition away from gas refrigerants, ionocaloric cooling will likely need government incentives, such as consumer rebates, to make the technology competitive with conventional units.

Dr. Lilley’s Insights into Ionocaloric Cooling

In addition to being environmentally harmful, gas refrigerants have proven to be costly and difficult to dispose of. Dr. Lilley believes that ionocaloric cooling can thus be an advantageous solution in a variety of ways. The end of life management (or disposal) of output components from ionocaloric cooling will be much easier as it relies upon liquid inputs. Additionally, Lilley notes that there is no way to completely seal refrigerants from the atmosphere, so a liquid refrigerant eliminates that problem altogether. As the technology becomes more advanced, Dr. Lilley believes that initial cost concerns will fade with state subsidies and market adoption.

Clean transportation policies promoting sustainability have progressed over the years and have become even more important, both because transportation represents the largest portion of greenhouse gas emissions and because climate change has been accelerating at unprecedented rates. The public is likely more familiar with zero-emission cars, but zero-emission trucks are also becoming an integral part of mitigating climate and other environmental impacts.

Transportation-based pollution

The transportation industry as a whole has been the biggest source of greenhouse gasses over the time period since the Industrial Revolution. Impacts of emissions associated with transportation include harm to the environment as well as to human health. Trucks and other heavy-duty vehicles constitute six percent of the on-road fleet but produce up to 26 percent of transportation-based greenhouse gas emissions along with a plethora of pollutants that can cause various types of cancer, asthma, and other respiratory challenges. Diesel-fueled trucks and other large vehicles can also cause noise pollution and take an out-sized toll on road infrastructure. 

Benefits of Zero-Emission Trucking

Zero-emission trucking can help reduce our reliance on fossil fuels and reduce both greenhouse gas emissions and emissions of other pollutants into the environment. By one estimate, US regions could save $735 billion in public health benefits due to cleaner air and result in 1.75 million fewer asthma attacks. The Inflation Reduction Act provides incentives for the manufacturing and purchasing of zero-emission trucks. People who buy zero-emission vehicles, for example, can receive significant tax breaks, subsidies, and even discounts on road tolls. Moreover, it is common for zero-emission trucks to be exempt from vehicle dimensions and weight restrictions

Drawbacks of Clean Trucks

Although zero-emission trucks–battery electric trucks and hydrogen fuel cell electric trucks–as a whole have a lot of advantages, they still face significant challenges. For example, clean trucks may still be ill-suited for the range demanded of long-haul applications. Even with IRA incentives, clean trucks can be two and a half to three times more expensive than the diesel equivalent, although the cost of fuel and maintenance is likely less. Battery electric trucks can take up to four times longer than their diesel equivalent to charge. And even though hydrogen-operated trucks are more efficient than battery electric trucks, the US currently lacks the necessary hydrogen infrastructure to make them truly feasible. 

In addition, hydrogen trucks, when fully charged, have a range that is about 500 miles and battery electric… [about] 180 to 250. By comparison, a diesel truck running a full load can have a range of roughly 1000 to 1200 miles. Because the sustainable alternatives are heavier, they actually would end up carrying less and more trucks would be needed to do the same amount of work as a single diesel-powered truck could, increasing operational costs and decreasing efficiency.

Aronin and Zero-Emission Mobility

Ruben Aronin is working to pave a path towards zero-emission mobility in the United States (especially California) with his team at Better World Group. They have worked to support multiple policies, including the Advanced Clean Truck Rule which is a significant part of California’s zero-emission truck policy. That rule mandates that manufacturers–provided with four years of lead time–increase electric truck vehicle sales every year from 2025. Additionally, it promotes a 100% sales requirement of zero-emission trucks by 2036. 

Mr. Aronin believes that the Advanced Clean Truck Rule along with another policy, called the Advanced Clean Fleet Rule, will enable the quickest transitions to zero-emission trucks, particularly in the most pollution-burdened communities. His coalition includes the Teamsters and others to help ensure labor and environmental justice support. He also recognizes that it is often economically difficult or unfeasible for companies and individuals to purchase zero-emission trucks. To this end, tax credits and investments from the federal IRA and IAJ are essential. As the market grows, Mr. Aronin says that the price of the electric truck components and batteries are decreasing at a rapid pace.

Who is Ruben Aronin?

Ruben Aronin, current principal of The Better World Group, acts to advance clean transportation policies. He joined the BWG in 2012 and currently helps to lead BWG’s advanced transportation project work. Aronin has previously created and implemented effective environmental policy initiatives to promote energy efficiency and renewable energy in over a dozen states across the country (including California).

As ocean temperatures increase due to climate change, an emergent crisis known as coral bleaching is on the rise. Coral bleaching poses the largest threat to coral reefs, which are some of the most diverse ecosystems in the world. Coral reef habitats occupy less than one percent of the ocean floor, but constitute more than 25% of all marine life, providing habitats for a vast array of species from small organisms to large fish and sharks. Additionally, biodiverse reefs provide a variety of economic benefits, supporting jobs, tourism, and fisheries. Reefs also protect lives and property in coastal areas, absorbing 97% of a wave’s energy while buffering against currents, waves, and storms.

However, when ocean temperatures rise, corals become stressed and expel the marine algae living inside their tissues, known as zooxanthellae. Typically, coral live synergistically with zooxanthellae, meaning the algae provide food for the coral while the algae use the coral as shelter. Due to stress, corals expel zooxanthellae, causing them to become a white skeleton. If the temperatures remain high, the coral won’t allow the algae back and the coral will die. Once corals die, reefs rarely come back. As climate change progresses with its warming trend, corals endure greater stress, and experience longer and more intense bleaching events. Between 2014 and 2017, 30% of the world’s reefs experienced heat-stress leading to coral bleaching. In 2005, the US lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event. Fortunately, marine biologists have been working on a new strategy to restore damaged coral reefs, known as Coral IVF (in vitro fertilization), which entails taking healthy coral eggs and sperm, crossing them in a supervised pool, and returning the mature coral to a damaged coral reef. Importantly, IVF coral are often bred to be resilient to heat-induced bleaching, making Coral IVF a successful strategy in fortifying reefs against bleaching.

What exactly is Coral IVF?

Coral IVF begins with biologists collecting spawn, or coral eggs and sperm, from heat-tolerant corals that have survived coral bleaching events. With these spawn, biologists can rear millions of baby corals in tanks and coral nursery pools before repopulating damaged reefs for restoration. So far, coral IVF has proven successful. The Great Barrier Reef (GBR) Foundation planted 22 large colonies of new baby corals off Heron Island in 2016. Four years later, the researchers found that the corals had survived a bleaching event and grown to maturity. The next year, the corals had reproduced and spawned babies of their own. 

In 2016, 81% of the northernmost section of the GBR was severely bleached, including mass bleaching in other sections. The GBR provides an estimated economic value of $56 billion, including 64,000 jobs stemming from the reef. Losing the reef would be a major economic loss for Australia, which has already lost 50% of its coral since 1995. With coral IVF, there is hope for an eventual repopulation of the reef with healthy corals. Beyond the GBR, coral IVF is taking place in reefs across the US, Mexico, and the Caribbean. Approximately 90% of IVF-created corals survived 2023’s heat wave, holding on to the algae that sustain them.

The Advantages of Coral Breeding

Coral IVF not only mitigates short term reef loss, but also strengthens reefs in the long term. One study revealed that corals in the GBR that survived bleaching in 2016 had twice the average heat tolerance the following year. Research reveals that corals can pass on their adaptive strategies to their offspring. Experiments also reveal that heat-adapted corals can thrive in new environments and be an important source of reef regeneration globally. This technique can therefore be applied to any coral population. Further, the IVF process also can be done quickly, allowing scientists to respond to coral damage in an emergency.

Climate change poses an insurmountable risk

Unfortunately, climate change still poses a threat to IVF created coral reefs. By 2049, annual bleaching events will become the norm in the tropics. Research reveals that as global temperatures rise, coral will become less tolerant to heat related stress. In Australia, there has been a massive bleaching event every other year for six years. Due to the frequency of such events, coral's ability to reproduce is compromised for a number of years. As global emissions continue to rise, temperatures will continue to rise, inducing further heat-related stress. Eventually, coral may not be able to live in excessively hot ocean waters. Coral IVF is an effective strategy to prepare corals for future temperatures, but likely only up to a certain point.

For over a century, native salmon populations in California have been adversely impacted by human activities such as mining, dam building, and overfishing practices, often leading to the loss of critical habitat and  decreased genetic diversity. With additional environmental stress from climate change, such as rising surface temperatures and changes in freshwater temperature and flow, salmon populations have been quickly declining. In addition, dams trap salmon into the warmest parts of the watershed, where they are more vulnerable to predators and have decreased breeding area necessary for their survival. Salmon are an incredibly important marine species, often referred to as a keystone species, as they play an essential role in the health and function of an ecosystem. Not only are salmon ecologically beneficial through their ability to disperse nutrients throughout streams and rivers, but they are also culturally significant to Indigenous people. Indigenous culture has historic ties to salmon, including reliance on the species for sustenance and livelihood. As a result, indigenous tribes have a particular attachment to and concern for salmon, and issues such as diminished water quality and the burdens brought about by climate change have a deep resonance. In order to restore salmon populations, Indigenous groups and environmental activists have advocated for increased restoration of watersheds, the reopening and improving of ecologically important areas, and the removal of dams that block natural salmon spawning habitats.  

Dam Removal as Solution to Climate Change

As climate change reduces water flows in California and increases temperatures beyond which salmon can tolerate, certain populations of salmon have become endangered species. Drastically reduced population levels have brought about a wave of concern, as their absence can disrupt nutrient cycling, reduce food availability, and negatively impact the livelihoods of people who depend on salmon for sustenance, income and cultural value. The “California Salmon Strategy” outlines actions for state agencies to stabilize and promote recovery of salmon populations. The plan envisions coordination among multiple state agencies, Tribal Nations, and federal agencies for implementation. 

In the late 19th century, treaties between Pacific Northwest tribes and federal agencies gave tribes the right to hunt, gather, and fish in “accustomed grounds” in exchange for land. However, by the mid-20th century, these agreements had largely been abandoned by the federal government, with states outlawing traditional methods of subsistence fishing. Coupled with increased development and resultant large-scale habitat loss, salmon populations have been on a steady decline. Tribal governments have long opposed the construction of dams in California, raising concerns of the devastating effects such construction has had on their way of life and the biodiversity of river ecosystems.

Therefore, one solution has been the removal of dams to allow for continual, unobstructed streams of water for salmon to move freely through. Large dams built in the early 1900s block salmon’s access to over 90% of historical spawning and rearing habitat in mountainous streams. The largest river restoration project is currently taking place on the Klamath River, located in Southern Oregon and Northern California, where dam removal is predicted to improve water quality and restore access to more than 420 miles of habitat. The lack of access to these cold waters for spawning was one of the primary reasons for the steady decline of California’s salmon population. Studies project that the removal of the Klamath Dam will reduce the river’s temperature by 2-4 degrees, which salmon prefer as cold water holds more oxygen, allowing for improved metabolism and the preservation of salmon quality, spurring new population growth.

In addition to dam removal, the California Salmon Strategy proposes expanding habitat for spawning and protecting water flow and quality in key rivers. By fostering collaborative efforts, the State of California and Tribal Nations hope to successfully restore salmon spawning habitats and reintroduce salmon through traditional ecological knowledge.

Benefits of Salmon Restoration

Salmon restoration will help restore genetic diversity, improve habitat, and foster resilience. Beyond ecological benefits, restoring salmon habitats will benefit local communities and restore their cultural significance. The removal of dams like that on the Klamath River has already been a huge success in reopening former habitat that historically supported diverse salmon populations, with significant salmon spawning showing signs of a rejuvenation of this endangered species. 

Challenges of Restoring Salmon 

Unfortunately, salmon will continue to face the threat of climate change, particularly due to the lack of cold, readily available water. Salmon’s migratory lifestyle patterns are also under threat from climate change, as a lack of cold water prevents survival at different stages of the life cycle in order to reach their spawning habitats in time. One major concern of the dam removal process is the short-term increase in turbidity and water quality problems during the removal process. There also could be the potential for disrupted habitats and short-term fish mortality due to the changing water quality dynamics. However, water quality problems usually pass after the initial slug of sediment moves downstream, allowing for long-term benefits to take hold.

The expansion of renewable energy has resulted in a heightened need for greater transmission capacity of the electrical grid. Unfortunately, permitting and cost allocation have been large hurdles to the potential of rapid expansion to meet future demand. As an alternative, large-scale reconductoring of advanced conductor systems has been proposed as a solution. Such an alternative can double transmission capacity cost-effectively, without the need to ensure additional permitting. In order to achieve this transition, old steel power lines would be replaced with carbon fiber, reducing electricity loss and boosting the overall capacity of the power grid. 

How does reconductoring work?

In order to achieve clean energy goals, it is vital that we increase power grid capacity. To briefly summarize, electrons travel along transmission lines between towers made of conducting elements and a strength member, which allows conductors to hang between towers. The most common type of reinforcement is ACSR, aluminum conductor steel reinforced, used in overhead electrical transmissions. ACSR is susceptible to degradation and breakage, which may lead to more frequent power outages and increased chemical runoff into the environment. As an alternative, ACSS has been proposed by researchers as it carries more current than ACSR and is supported at higher temperatures. 

According to recent studies by the Goldman School and GridLab, replacing power lines with advanced conductors would enable 90% clean electricity by 2035. The report revealed that reconductoring transmission lines could add approximately 65 TW-miles of new interzonal transmission capacity in ten years, compared to 16TW-miles from building only new transmission lines. In terms of pricing, implementing advanced conductors costs around 20% more than building new lines. Yet replacing old lines with advanced conductors is typically half the cost than building new lines for the same capacity, partly because you reuse old infrastructure and the new models are much more energy efficient. Further policy and legislation is necessary in order to drive this technology into the future and ensure proper permitting, funding, and planning. 

What are some of the benefits?

Advanced composite-core conductors such as ACSS can carry double the existing capacity, operate at higher temperatures, and reduce line sag. Further, replacing the steel for a stronger yet smaller composite-based core can avoid the construction of new lines which bring about land acquisition and increasing permitting. There is already a growing movement towards reconductoring, as 90,000 miles of advanced conductors have been deployed globally. More advanced conductors also have the benefit of being cost-effective, with an estimated $180 billion in systems cost savings with more long-term structure. Advanced conductors enable a doubling of line capacity at less than half the cost of new lines. Alongside the benefits, at large, reconductoring can play a pivotal role in low-cost decarbonization of power systems.

What are some of the drawbacks?

Amidst the potential advantages are obstacles that may impede the future progress of reconductoring. First, there is a lack of awareness. Conventionally, the only way to expand the grid capacity has been to build new lines. Utilities are not aware of the existing solution and often fail to take reconductoring into account. Alongside this is a lack of experience and misconception that implementing reconductoring lines is difficult and unrealistic. As there is a lack of incentives for utilities to improve their products, cheaper solutions are not enticing for their rate of return regulation. Particularly if reconductoring only occurs in localized areas as opposed to system-wide implementation, the benefits may be limited. Thus, government prioritization of this new solution is critical in order to boost conductor efficiency.

In the transition to clean energy, state public utility commissions (PUCs), which regulate electric, gas, telecommunications, water and wastewater utilities, play an increasingly important role in achieving energy efficiency, enabling renewable energy, and implementing policies for greenhouse gas emissions reduction. PUCs  play a pivotal role in determining the energy mix, setting rates, and deciding on investments in infrastructure, such as electric vehicle (EV) charging stations. The California Public Utilities Commission (CPUC), for example, has to balance  safety, reliable utility service, and reasonable rates through the regulation of various large investor-owned electric, natural gas, and water utilities. Utility commissions like CPUC are given a statutory mandate to ensure reasonable, adequate and efficient service to customers at just and reasonable prices. PUCs can issue regulations that impact electricity generation, the adoption of clean energy, and related emissions of pollutants and GHGs. PUCs can play an important role in shaping energy infrastructure, policy, and clean energy development.

The Role PUCs play in shaping energy infrastructure

PUCs were first created in the early 20th century to focus on overseeing operations and the utility investment in service while ensuring affordable rates. That role has evolved, and now PUCs often play a transformative role in transitioning towards a greener economy. PUCs have the ability to consider the impacts of GHG emissions, equity, grid reliability, distributed energy resources, and increased consumer choices in their policy decisions. 

PUCs oversee planning processes that affect a utility’s resource portfolio and therefore its environmental profile. A new method of planning amongst PUCs has emerged known as Integrated Resource Planning (IRP), which compares the life cycle costs of different resource choices that factor energy efficiency into their analysis. Portfolio standards have also been added to IRP, which requires certain types of resources to be included in the utilities’ mix of power procured, including renewable energy and energy efficiency. PUCs can also incorporate environmental considerations by increasing oversight of utility planning processes, setting prices, determining clean energy targets, and addressing utility incentives related to energy efficiency and distribution. PUCs thus have the ability to promote and shape clean energy adoption and development through their regulatory oversight. 

The Case for PUCs

State PUCs have significant authority, often includingI the ability to accelerate decarbonization of the energy sector, mitigate the impacts of climate change, improve public health, and assist in reaching state energy goals. Updated PUC statutory mandates that reflect state energy priorities can contribute to their success in transforming the energy grid to become more energy efficient. Energy efficiency is a cost-effective mechanism to meet future demand for electricity. Energy efficiency reduces the amount of electricity needed to meet demand thereby benefiting the overall reliability of the electric grid. With more efficient systems, utilities and states will not need to build as much new transmission and generation, which can save money and improve environmental quality. Further, modern regulations to achieve such priorities and framing for the public interest can incorporate climate and environmental justice concerns. 

The Case Against PUCs

Organizational challenges such as outdated mandates, staff constraints, gaps in technical knowledge, misinformation, and quasi-judicial processes have created barriers to innovation amongst PUCs. Some PUCs still continue to view themselves as purely economic regulators, which does not accurately reflect the current decisions they are being asked to make. Additionally, the authority of PUCs varies widely from state to state. PUCs authority is established by state legislatures, thus their power only extends as far as their statutory authorization. The level of statutory authority delegated to PUCs by legislatures also varies widely. Barriers such as these have made it difficult for some  PUCs to develop more innovative mechanisms consistent with new environmental targets and the effort to achieve a zero-carbon US grid.

While transitioning to clean energy promises long-term savings and environmental benefits, the short-term costs can be significant and potentially burdensome for consumers and businesses, posing political and fiscal challenges for PUCs. Stakeholder engagement in this transition will be vital. Labor issues also pose challenges as states transition away from  fossil fuels. In addition, challenges exist around regulatory complexities and the evolving federal and state policies.

Sustainable wood refers to the use of mass timber, which involves smaller pieces of wood that are dried and glued together in a perpendicular, crosswise pattern to form large slabs. This process can incorporate a closed-loop system that repurposes wood, promoting a circular practice that minimizes wood waste and reduces landfill usage, transportation needs, and carbon emissions. Additionally, the wood retains the carbon absorbed by trees during their growth, storing it in the floors and walls of buildings. As infrastructure demands increase, sustainable wood offers an environmentally friendly solution to meet these needs.

Why the Construction Industry Needs Sustainable Wood

Sustainable wood, particularly through the use of mass timber, is gaining recognition as a critical climate solution in the construction industry. Traditional building materials like concrete and steel are carbon-intensive to produce, responsible for nearly 8% of global carbon emissions. In contrast, mass timber is derived from a renewable resource: trees. Through responsible forest management, trees can be harvested and replanted in a sustainable cycle, allowing forests to continue absorbing carbon dioxide. The wood used in mass timber stores this carbon long after the trees are cut down, effectively sequestering it in the walls, floors, and structures of buildings for decades or even centuries. This makes sustainable wood not only a viable building material but also a carbon sink, helping reduce the overall carbon footprint of new construction.

The production of mass timber involves using smaller, fast-growing trees that are often thinned from forests to maintain ecological health. These pieces of wood are dried and glued in layers, forming large, strong panels that can be used for walls, floors, and even entire building frames. This technique reduces waste by making use of smaller trees or leftover wood that might otherwise be discarded. Additionally, mass timber is much lighter than steel and concrete, reducing the energy needed for transportation and lowering emissions from construction sites. The process can also incorporate repurposed or recycled wood in a closed-loop system, further contributing to the circular economy and minimizing waste.

The climate benefits of sustainable wood go beyond carbon storage. Timber construction has a much lower embodied carbon than steel and concrete, which require energy-intensive processes to extract and manufacture. By substituting these materials with mass timber, builders can reduce carbon emissions by up to 70%. In regions where sustainable forestry practices are employed, this approach also supports local ecosystems by preventing deforestation, protecting biodiversity, and encouraging the regeneration of forests. Importantly, mass timber’s design allows for prefabrication, which reduces construction time and waste, making it not only a greener option but also an economically competitive one.

As cities and communities around the world grapple with the need for affordable housing while also addressing climate change, sustainable wood provides a promising solution. By scaling up the use of mass timber in mid- and high-rise buildings, the construction sector can reduce its reliance on carbon-heavy materials, sequester large amounts of carbon, and promote sustainable forest management practices. This integration of environmental, economic, and social benefits positions sustainable wood as a key player in the transition toward a low-carbon future.

The Future of Sustainable Wood: Making Construction Faster and Greener 

Sustainable wood, especially when derived through the use of mass timber, offers a range of environmental, economic, and structural advantages over traditional building materials. From a structural standpoint, mass timber is both strong and lightweight, making it a highly versatile material. It has a high strength-to-weight ratio, allowing it to be used in large, multi-story buildings while reducing the overall load on foundations and minimizing transportation costs. Additionally, mass timber is more fire-resistant than many people realize; when exposed to fire, the outer layer of the wood chars and insulates the inner core, slowing down the spread of fire and maintaining the building’s integrity for longer than some steel structures. This combination of strength, fire resistance, and flexibility gives mass timber a competitive edge in construction.

Economically, sustainable wood offers cost-saving opportunities through faster construction times and less material waste. Mass timber panels can be prefabricated off-site, reducing the time spent on construction and the labor costs associated with traditional methods. This efficiency not only lowers the overall cost of building but also minimizes disruption in urban areas. Furthermore, the use of repurposed or recycled wood supports a circular economy, where resources are reused rather than discarded, reducing the environmental impact and fostering a more sustainable construction industry. As demand for sustainable and affordable housing rises, mass timber presents a compelling, eco-friendly alternative to conventional building practices.

One of the most significant benefits is its ability to sequester carbon. Trees naturally absorb carbon dioxide from the atmosphere as they grow, and this carbon remains stored in the wood even after it’s used in construction. By utilizing wood in buildings, the carbon is locked away for the lifespan of the structure, helping to reduce overall greenhouse gas emissions. In contrast, materials like concrete and steel release large amounts of carbon during their production, contributing to climate change. This makes mass timber a powerful tool in the fight against global warming, especially when paired with sustainable forestry practices.

Sustainable Wood Skepticism

Despite its many advantages, the use of sustainable wood and mass timber as a building material does have some drawbacks and criticisms. One primary concern is the reliance on sustainable forestry practices. If forests are not properly managed, large-scale timber harvesting can lead to deforestation, habitat destruction, and biodiversity loss. The success of mass timber as a climate solution depends on responsible sourcing, including replanting trees to maintain the carbon-absorbing benefits of forests. Unsustainable logging practices or overharvesting could negate the environmental benefits of mass timber by releasing more carbon into the atmosphere and harming ecosystems.

Another challenge is the perception of wood’s durability and fire safety. While mass timber is engineered to be fire-resistant, some critics remain concerned about its performance in large-scale buildings. Public perception and regulatory hurdles can be barriers to adoption, as many building codes and fire safety standards are based on traditional materials like concrete and steel. These regulations may need to be updated to reflect the true performance of mass timber, but in the meantime, they can slow down its widespread use in urban construction.

Additionally, there are economic concerns, particularly regarding initial costs. While mass timber can reduce construction time and labor costs, the price of sustainably sourced wood can be higher than that of conventional materials, especially if demand outstrips supply. The infrastructure for large-scale mass timber production is still developing, and until it reaches full maturity, the material may remain more expensive and less accessible than concrete or steel, limiting its adoption in some markets. Over time, these challenges may be addressed, but they highlight the need for careful planning, regulation, and investment in the mass timber industry.

Since the Industrial Revolution, our soils have lost between twenty and sixty percent of their carbon levels as a result of agricultural practice exacerbated by more common and more extreme droughts and floods resulting from climate change. Farmers have witnessed their crops endure mass devastation as a result of these unprecedented environmental disasters. Hence, the loss of carbon in soil threatens the stability of both the agriculture industry and global food security. 

Why Does Soil Need Carbon?

Stable carbon storage in soil is crucial for healthy soil and supports resistance to climate vulnerability. But how? A 1% increase of carbon in soil equates to a two percent increase in its water-holding capacity, in turn creating more drought-resistant soil that can better weather extreme climate variability. By enhancing its water-holding capacity, as well as nutrient retention rates, stable carbon contributes to both the structure and function of soil. Consequently, soil health and productivity are contingent on soil’s carbon content. By recognizing that stable carbon storage within their soil can lead to more nutrient-dense crops and bigger yields, farmers have a clear economic incentive to seek agricultural solutions that can reduce the current rate of carbon loss their crops are experiencing.

The Future of Fungi: Building Resilient Soil Ecosystems

Based in Orange, New South Wales, Australian biotech start-up Loam Bio has developed a new way to remove carbon dioxide from the atmosphere and store it underground. The solution, a microbial fungi-based seed treatment, is far less complex than one might initially think, simply requiring farmers to sprinkle the ground-up dust of fungal spores onto seeds actively used in their planting systems. As crops grow from those seeds, the fungal spores attach themselves to the roots. The tendrils of the fungus then extract the carbon that has been absorbed by the crop it latched onto.

Plants, on their own, sequester carbon from the atmosphere—a process crucial to mitigating fossil fuel emissions. The microbial fungal treatment leverages that sequestration by reducing the plants’ natural emissions of carbon. This particular type of microbial fungi, therefore, provides a level of protection against standard plant respiration, thereby reducing the amount of carbon returned to the atmosphere and instead storing it in soil for a longer period than the natural carbon cycle. 

Loam Bio relies on a cross-disciplinary team ranging from geneticists to mycologists to plant physiologists to carbon methodology experts. For example, the fungi and other organisms involved in the treatment are pre-screened through a genetic selection process that evaluates whether they are safe to introduce to the agricultural landscape and can effectively interact with the herbicides and fertilizers that may be used in crop production. The success of the fungi, however, is ultimately dependent on the soil type and the climatic environment of the respective farm to which it is being applied via seed treatment. 

Soil Expert Skepticism

While there is hope within the science community for the potential of the uptake of carbon in soil as a climate solution, some experts remain skeptical of whether the use of microbial fungi in field tests will translate to a meaningful impact on the carbon release of crops on operational farms.  Further testing and monitoring will be required for a full evaluation of the benefits and impacts.  

The agriculture industry relies on intensive farming practices that are increasingly worsening soil erosion and overall decreasing the quality of farming soil, including depleting the soil’s carbon content. Loam’s Bio initiative provides one possible pathway to try and reverse this consequence of industrial farming. So far, Loam Bio has had some encouraging results, achieving soil carbon content levels of 6%—far surpassing the US average of 1-4%. This revolutionary treatment has the potential to transform soil into an invaluable carbon sink, even more than it is now.

UC Berkeley chemistry professor Dr. Omar Yaghi recently led a study which has the potential to be revolutionary in reducing the quantity of carbon dioxide present in the atmosphere. “Covalent organic framework number 999,” or COF 999, is a yellow, powder-like material that has billions of tiny holes. Inside of these holes, researchers in Dr. Yaghi’s lab have installed molecular units that can seek out carbon dioxide, enabling the substance to suck in and capture the carbon dioxide. COF 999 has a huge capacity for absorbing emissions; half a pound of the powder can absorb as much carbon dioxide as a tree captures in a year.

The carbon dioxide problem

The quantity of carbon dioxide in the atmosphere has reached an all-time high, with a global average in 2023 of 419.3 parts per million. This immense amount of carbon dioxide in the atmosphere comes from a number of human sources, the most common of which is the burning of fossil fuels such as coal, oil, and natural gas for energy. Carbon dioxide is the most abundant greenhouse gas in the atmosphere, and contributes significantly to global warming and other environmental issues, including ocean acidification.

Applying COF 999 

In an interview with Forbes, Dr. Yaghi described the way he sees COF 999 being implemented as a solution. The powder can be made into pellets or a coating, and then integrated into facilities where flue gas –the gas that is released from industrial processes –is released. “This flue gas would pass through the material and because it just plucks out CO2, it cleans CO2 from that flue before it reaches the atmosphere.” According to the San Francisco Standard, Dr. Yaghi says that the powder “requires no energy, shows no signs of degradation even after 100 uses, and is made from inexpensive, commercially available materials.”  Another benefit is that the material only needs to be heated to 50 or 60 degrees Celsius, rather than to 120 like many other traditional materials necessary for carbon capture.

In order to see significant change in the atmosphere’s carbon dioxide concentration, we will need to couple preventing carbon dioxide emissions with direct air capture, which COF 999 can also do. According to Zihui Zhou, a UC Berkeley graduate student who worked in Dr. Yaghi’s lab says, “Currently, the CO2 concentration in the atmosphere is more than 420 ppm, but that will increase to maybe 500 or 550 before we fully develop and employ flue gas capture. So if we want to decrease the concentration and go back to maybe 400 or 300 ppm, we have to use direct air capture.” It will take time, however, for scientists to be able to use COF 999 effectively. This is because the powder has not been tested in real-life scenarios, and therefore the costs and risks from the powder are largely unknown; for example, the powder might restrict air flow through filters when applied, reducing the practicality of the powder.

Mechanical textile recycling is a process by which used textiles, particularly those made with natural fibers such as cotton, wool, and linen, are broken down into their individual fibers and then spun into yarn or fabric for reuse in the production of new textiles.  Textile recycling has the potential to reduce waste and greenhouse gas emissions associated with textile production.    

Mechanical textile recycling involves a series of steps: It typically begins with the collection of used textiles, which are sorted according to their fiber type and quality.  Next, the textiles are cleaned and processed to remove impurities and contaminants such as buttons, zippers, and other non-textile materials.  Once the textiles have been cleaned and prepared, they are typically shredded or ground into small pieces. These pieces are then subjected to a series of mechanical processes—such as carding, combing, and drawing—to separate the fibers from one another.  The resulting fibers are then spun into new yarn or woven into new fabric. The new yarn or fabric can be used in a variety of products, such as clothing, linens, and industrial products, such as building insulation. 

Mechanical textile recycling could reduce demand for new clothing and other textiles, which could reduce the carbon footprint of the fashion industry.  The global fashion industry is a major contributor to global greenhouse gas emissions: In 2018, it produced around 2.1 billion tons of greenhouse gas emissions, equaling between 4% and 10% of the global total—equal to or greater than the annual greenhouse gas emissions of France, Germany, and the United Kingdom combined.  About 70% of these emissions came from upstream activities such as textile production, preparation, and processing.  The remaining emissions came from downstream activities, including the disposal of textiles in landfills, where they release methane, a potent greenhouse gas, as they decompose. 

Mechanical textile recycling is a relatively new technology that faces certain technical and economic challenges, including limited ability to recycle synthetic fibers or fiber blends, and a lack of textile recycling infrastructure.  For now, according to CalRecycle, the best way to reduce the environmental impact of textiles is “by reducing the amount of textiles we purchase, use, and dispose.”   

What does Material Return do, and who is Bobby Carswell?

Material Return is a textile recycling cooperative based in Morgantown, North Carolina, that works with local manufacturers and national brands to transform textile waste into new products.  Material Return recently partnered with Smartwool, an American clothing producer, to collect 400,000 pairs of used socks to recycle them into yarn for use in new socks and other circular clothing products. Bobby Carswell is the research and development director at Material Return.

Community Choice Aggregation (CCA) is a system that allows local governments to purchase power directly from an energy supplier other than the existing utility. This means that while the existing utility continues to deliver the power, the CCA buys and generates the power itself, potentially from renewable sources. CCAs continue to pay fees to the existing utility for energy transmission and backup power.        

While not required, CCAs can set ambitious climate goals that exceed state-mandated targets and drive decarbonization efforts by investing in emerging clean energy technologies. CCAs can take risks to transform their energy sources and grid in ways that traditional investor-owned utilities may be reluctant to try. When successful, CCAs can reduce electric rates for consumers and drive investment in local energy programs. But CCAs without sufficient capital may face financial and operational challenges.    

CCA programs are authorized in various states, including California, Illinois, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Ohio, Rhode Island, and Virginia. 

How does it work?

In states with enabling legislation, local governments can create a CCA by holding public hearings and passing a law authorizing CCAs. Participation in CCAs is voluntary, with most programs having opt-out provisions. This means customers are automatically enrolled in the program unless they choose to opt out and continue receiving electricity from their current supplier. Some CCAs may have opt-in provisions, requiring customers to actively enroll in the program. Customers under CCAs continue to receive delivery and maintenance services from their existing utility and receive a single utility bill reflecting the change in electricity generation sources and prices.

What are the pros and cons?

Advantages of CCAs include the potential for retail electric rate reductions, the ability to shift to greener power resources quickly, local control over electricity generation aligned with local goals, expanded consumer choices, and the potential to stimulate local job creation and renewable energy development. However, there are also challenges associated with CCAs, including dependence on enabling state legislation, navigating CCA regulations and ordinances, administrative costs, consumer confusion over opt-in and opt-out clauses, and potential resistance from utilities in traditionally regulated electricity states facing new competition from CCAs.

What is Central Coast Community Energy?

Central Coast Community Energy (3CE) is a CCA program that has procured and provided electricity to residents and businesses in Monterey, San Benito, Santa Cruz, and Santa Barbara counties in California since 2018. It is governed by board members who represent each community served by the agency.

3CE recently approved a contract to build the world's largest Compressed Air Energy Storage (CAES) facility, which will provide 500 megawatts of energy storage. 3CE will reserve 200 megawatts of that capacity to help achieve its goal of serving 100% clean and renewable energy to its customers in Santa Cruz and Santa Barbara counties by 2030. The CAES technology uses underground caverns to store compressed air, which is later released to generate electricity, offering long-duration storage beyond the capabilities of lithium-ion batteries, and supporting grids reliant on intermittent renewable energy.

Sea level rise due to climate change will directly impact at least 70 countries, many of them small, low-lying island nations. Though their contribution to climate change is very little, they face some of its worst consequences. This is not a new issue, and tension has been building since the late 1980s. In 1989, the Maldives, an island nation in the Indian Ocean, issued an international declaration, the first of its kind, calling attention to sea level rise due to climate change, and how it impacts its land. Island states often have small land area, but, under international law, have jurisdiction over a larger area of their surrounding seas for economic purposes. What if an island loses territory due to sea level rise? If so, it could lose its economic zone. This is also a national security question; could another nation then legally take over this economic zone? Currently, the international law framework, called the Law of the Sea, does not answer these questions even though the  livelihoods of millions are at issue. A 2021 declaration by Pacific Island nations calls for maritime boundaries to stay where they are now regardless of sea level rise. However, this requires the endorsement of other nations. The United Nations, up until now, has paid comparatively little attention to this issue, but, through its study group on sea-level rise, the UN is aiming to engage non-low-lying island nations, and attempt to resolve these and other questions. 

Climate Refugees Need Protected Status Under the Law

By 2050, there could be 1.2 billion climate refugees, according to the international think tank International Environmental Partnership. But these refugees often do not fit the legal definition of “refugee”, including individuals displaced in the United States. Becoming a “refugee” under the law confers special status; it protects from deportation, for example. In 2013, a man from Kiribati, a country undergoing severe sea level rise, applied for refugee status as a “climate refugee” in New Zealand. His application was denied, and he was repatriated to Kiribati. The man subsequently filed a complaint with the UN Convent of Civil Liberties, claiming his right to life had been violated. The man lost his case, because his life was not found to be under immediate danger. However, the wording of the UN’s ruling in the case asserts that those fleeing a climate crisis cannot be sent home, thereby creating a non-binding international construct. This case illustrates some of the complexities raised by climate refugees and how they are currently viewed in many of the world’s legal systems.  Sea level rise is not only an issue of the future but already an issue of the present. 

Who is Dr. Nilufer Oral?

Dr. Nilufer Oral is director at the Center for International Law at the National University of Singapore. She is also a member of the International Law Commission at the United Nations and co-chair of the study group at the UN on sea level rise in relation to international law.

One-third of all food produced is wasted every year – approximately 1.3 billion tons. The UN Environment Program estimates that 3.3 billion tons of CO2 are emitted annually from the resources used to produce wasted food. In the United States alone, 133 billion pounds of edible food, valued at $161 billion, is wasted every year. 

Replate’s Solution

Enter Replate: a technology-based nonprofit that works to reduce food insecurity and waste while mitigating food waste´s effects on climate change. The organization provides a solution for businesses to donate surplus food to nearby nonprofits operating throughout the United States and the Middle East. Replate’s services are designed to prevent such food waste through source reduction and donating meals to communities experiencing food insecurity. Its algorithm connects donor organizations to nonprofits, diverting food from landfills while increasing food access. 

How Replate Works

Their organization operates through a web app. Donors can schedule pick-up services, then track the environmental and social impact of their donations. Nonprofits can sign up to receive donations using an online form. Replate then works to understand these organizations' capacity and food needs before drop off. Replate works with hundreds of corporations including Netflix, Boston Consulting Group, Whole Foods, Chipotle, Walmart, and more to match businesses with communities in need. Since its founding, Replate has recovered over 3.6 million pounds of food, delivered over three million meals, and served 301 nonprofits. It estimates that to date the program has saved 985 million gallons of water and diverted 3,686 tons of carbon emissions.

Connections to California Composting Goals

As organic material like food and agricultural waste decomposes, it releases methane, a greenhouse gas eighty-four times more potent than carbon dioxide in the atmosphere over a 20-year period. Enacted in January 2022, California’s Short-Lived Pollutant Reduction law SB-1383 targets is trying to address methane emissions due to organic waste. SB-1383 is expected to reduce California’s methane emissions from organic materials in traditional landfills by an estimated twenty percent. As part of the law, large food service providers, distributors, and industries falling under the Tier 1 category—food service providers, food distributors, wholesale food vendors, supermarkets and grocery stores over 10,000 square feet—are required to reduce their organic waste material disposal. Platforms like Replate can help businesses reduce their food waste and comply with SB-1383. 

Maen Mahfoud is the founder and CEO of Replate. Witnessing the alarming levels of food insecurity, and enormous amounts of food waste in the Bay Area, his knowledge of the massive effects of food waste on our planet motivated Mahfoud to launch Replate in 2016. Maen is a DRK entrepreneur, a 2023 recipient of the James Irvine Foundation Leadership, and was sponsored by Harvard Business School's Executive Program. Mahfoud holds a Master’s in Public Health from Imperial College London, a degree in Molecular Biology from UC Berkeley, and a Human-Computer Interaction for User Experience Design Certificate from MIT.

Globally, 1.9 billion metric tons of crude steel were produced in 2022. Over the past 15 years, the global demand for steel production has nearly doubled, as this versatile product can be found in nearly all modern infrastructure such as buildings, ships, vehicles, machines, and appliances. Conventionally, steel is made from iron ore (the world’s third most produced commodity by volume), which is a compound derived from iron, oxygen, and other minerals. Through a blast or electric furnace, in which electricity is used to create high-temperature environments to melt the reactants, the final product of steel is generated following a molting refining process. Unfortunately, steel production is extremely energy-intensive and accelerates air pollution through the release of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide. On average, 1.83 tons of CO2 is emitted for every ton of steel that is produced. Steel production accounts for nearly 7-11% of total global greenhouse gas emissions emitted annually. Steel production not only has harmful environmental impacts, but can negatively impact human health leading to respiratory diseases such as asthma, COPD, and cancer. 

What is Green Steel?

To mitigate the harmful environmental and health effects of conventional steel production, many researchers  are working on green steel as an alternative. Green steel is a form of steel production that is powered by hydrogen or renewable energy, which can reduce carbon dioxide emissions and minimize waste. Green steel can be accomplished through various methods, whether by reducing carbon-based agents, moving from blast to electric furnaces, or decreasing reliance on fossil-fuel based inputs. 

In traditional steel production, CO2 emissions generally arise from the use of coal and coke to remove oxygen from iron ore. Green steel utilizes hydrogen rather than coal or coke. When burned, hydrogen emits only water, so this phase of manufacturing is free of carbon dioxide emissions. As a result, water is the only byproduct which can then be used to produce more hydrogen, forming a closed loop system. Throughout production, green steel utilizes either wind, solar or hydro to power the furnaces instead of fossil power. Scrap materials of used steel can also be utilized, reducing the need for extracting additional primary materials. 

The Future of Green Steel

Green steel production is on the forefront of innovative design in equipping regions like the Rust Belt with strategies to significantly revitalize their current operations. Last March the Biden-Harris Administration announced a $6 billion funding from the U.S. Department of Energy to accelerate decarbonization projects in energy-intensive industries like steel production. Such  investments aim to spearhead the transition to renewable energy sources, focus on investment in new carbon technologies, enable markets to build cleaner products, and benefit local communities. Additionally, a transition to hydrogen-based electric manufacturing could increase jobs in the steel and energy industries by 43 percent. Overall, green steel can conserve resources, promote economic growth, and assist in decarbonization. 

Scaling Up the Technology is Proving Troublesome

Steel has posed to be one of the most challenging industries to decarbonize. On a large scale, clean hydrogen production will require billions of dollars in investment to achieve a full transition. Currently, the cost of production of green steel is higher than conventional steel due to the high investment and electricity costs required. Labor, finance, and advanced technology will be essential in scaling up green steel production.

As the effects of climate change rise in prevalence, all facets of the global economy will be affected. In order to address many of the global environmental crises of today, such as biodiversity loss and extreme drought, entrepreneurs are looking into sustainable investment initiatives as a tool for change. Sustainable investing is a process that directs investment capital to companies and businesses actively working to prevent environmental destruction. Sustainable investments often follow an Environmental, Social, and Corporate Governance (ESG) framework, which seeks to promote socially conscious investments. Similar to Corporate Social Responsibility (CSR), which refers to a company’s commitment to operating ethically, ESG goes one step further in providing an assessable outcome of a company’s overall sustainability performance. Thus, ESG lays a foundation for investors in determining which corporations operate sustainably. 

Current Climate of Sustainable Investment

From 2021 to 2026, institutional investment in ESG projects is expected to increase by 84%. The World Economic Forum recently published a report noting that over $200 billion is required annually in order to meet adaptation and resilience investment targets, which is three times the current funding. Such investing in adaptation and resilience could reduce exposure to climate risks and yield financial benefits for stakeholders involved. Although climate financing is slowly on the rise, there remains minimal progress in climate-vulnerable and high-emission countries. 

There are various types of sustainable investing, operating through registered investment companies, alternative investment funds and community investments. The US Sustainable Investment Forum identified 645 registered investment companies with $1.2 trillion sustainable investment AUM in 2022. Not only does sustainable investment cover private equity investments, but also cash, fixed income, and alternative investments. Sustainable investments, like conventional investing, receive a return on their investments. Reports from the Morgan Stanley Institute for Sustainable Investing found no financial trade-off between sustainable investing compared to traditional investment initiatives. 

Does sustainable investing provide hope for the future?

Investing in sustainable industry, infrastructure, and business has the potential to provide a more climate-proof economy for all. For private investors, effective investments in areas vulnerable to climate change could reduce disruptions in the supply chain, thereby boosting labor productivity and lowering operational costs. As such, companies will have the tools in place to be able to respond to vulnerabilities when they arise while still maintaining a profit. Additionally, ESG investing has been proven to provide downside protection during social or economic crises according to the NYU Stern Center for Sustainable Business. Such protection may be pertinent in a world more susceptible to the adverse effects of climate change. Many studies corroborate such findings; a meta-study conducted by Oxford University in 2015 revealed that 88% of companies with robust sustainability practices demonstrate better operational performance, translating into higher cash flows and positive effects on investment performance.

Greenwashing and ESG Concerns

One concern within the world of sustainable investment is largely centered around the question of whether organizations will be willing to take more or less risk to achieve an impact. Companies that prioritize sustainability may be more volatile than traditional companies, creating fear around the uncertainty of consistent returns. Further, there is often confusion on how to make a good return on investment when choosing to invest in more socially responsible companies. 

The rise of sustainable investment has brought about potential concerns related to greenwashing, in which a company’s ESG credentials or potential sustainability initiatives may be over-embellished, leading to falsified information. On the other hand, many investors prioritizing sustainable investment initiatives have received a surge in backlash against their new initiatives, mainly from Republican politicians. A recent study by The Conference Board revealed that 48% of surveyed businesses have experienced backlash to their ESG policies or activities, potentially deterring companies from further pursuing such initiatives. An increase in educational awareness is vital to inform investors of the benefits of sustainable investing and ways to do so responsibly amidst criticism.

As defined by the U.S. Geological Survey, “carbon mineralization is the process by which carbon dioxide becomes a solid mineral, such as a carbonate…The biggest advantage of carbon mineralization is that the carbon cannot escape back to the atmosphere.” This generally occurs by injecting carbon dioxide underground into certain rock formations so the carbon dioxide takes on a solid form: trapped and unable to reach the atmosphere. 

How does carbon mineralization work?

Two of the main methods in which carbon mineralization occurs are ex-situ carbon mineralization and in-situ carbon mineralization. With ex-situ carbon mineralization, carbon dioxide solids are transported to a site to react with fluids—like water—and gas. In-situ carbon mineralization is the opposite—fluids containing carbon dioxide are funneled through rock formations in which it solidifies. Both of these methods result in carbon dioxide trapped in a solidified form. 

In a third method of carbon mineralization, surificial mineralization, carbon dioxide reacts with alkaline substances—such as mine tailings, smelter slags, or sedimentary formations—which result in the carbon dioxide taking on a solidified form. In the case of in-situ carbon mineralization or surificial mineralization, carbon dioxide can react with surface water rather than an artificial fluid, replicating natural processes of carbon mineralization.

Currently, the biggest drawbacks and barriers preventing carbon mineralization from taking hold as a major climate solution lie in cost and research uncertainties regarding environmental risks. In terms of cost, the price for carbon mineralization is high: 5 million dollars per well to inject carbon dioxide into rock formations. Further, the risks for groundwater and its susceptibility to contamination through this method is unknown, and the potential side effects of contaminating water formations could be devastating for ecological communities which thrive off of these water systems.

Many of the solutions we often hear about when it comes to reducing greenhouse gas emissions revolve around reducing carbon emissions, as carbon dioxide (CO2) is the primary greenhouse gas emitted by human activities. Methane, however, is the second most common greenhouse gas, emitted through agricultural practices, landfill waste, coal mining, and oil and gas operations. While methane generally receives less attention than carbon dioxide when it comes to climate solutions, recent studies have shown that it is a more potent greenhouse gas than carbon dioxide. According to the United Nations Economic Commission for Europe, methane has a global warming potential 28-34 times higher than CO2 upon emission, which increases to 84-86 times over a 20-year period. 

How does methane enter our skies?

The concentration of methane in the atmosphere has more than doubled over the past century. Both everyday infrastructure in older cities and major leaks at oil and gas fields add to the quantity of methane into the atmosphere. As for the source of these leaks, they are largely caused by equipment failures or faulty pipes and vessels. 2,595 gas incidents have been reported in the US from 2010 to 2021, adding up to 26.6 billion cubic feet of methane gas emitted. Methane impacts both the climate system and public health; breathing methane can cause damaged airways, lung diseases, asthma attacks, increased rates of preterm birth, cardiovascular morbidity and mortality, and heightened stroke risk.  

What can we do?

Mining operations can be improved to reduce methane leaks and oil and gas operations can greatly reduce emissions throughout the system. As our tools of measurement and technology improve, the world has realized the greater need to attack methane emissions, which led to the Global Methane Pledge in 2021. In this pledge, 158 countries and the EU pledged to make a distinct effort to reduce global methane emissions by at least 30 percent from 2020 levels by 2030. 

Part of reducing methane emissions involves switching from fossil fuels to electricity generated from renewable sources.  According to Environmental specialist and Stanford professor Dr. Rob Jackson, our skies will become cleaner once we switch to cleaner, electrical energy sources, including electric heat pumps to cool and heat our homes, electric water heaters, and especially electric stoves. According to the Journal of Environmental Science and Technology, methane emissions from gas stoves in America—when scaled to the 20-year global warming potential of the gas—were “comparable to the carbon dioxide emissions of approximately 500,000 gas-powered cars.” Health-wise, a study conducted by Stanford’s Doerr School of Sustainability and PSE Healthy Energy found that “children who live in homes with gas stoves had a 24% higher risk of lifetime asthma and a 42% increased risk of having asthma currently.” Dr. Jackson says that making the switch to induction stoves is not only energetically cleaner and prevents the likelihood of gas leaks, but it also prevents us from being exposed to toxic pollutants such as nitrogen oxides and benzene gasses that come from gas stoves.

Some potential drawbacks: the cost of electricity

While induction stoves and a cleaner, electrical society sounds optimal, there are some challenges and barriers to making this a reality. First of all, not every person can afford to implement an induction stove and replace their functioning gas stove, as home renovations, rewirings, and big purchases such as a new stove cost a great deal of money. In this way, income inequality plays a major role in the way climate change impacts different people in society. Dr. Jackson uses the example of a person living in a lower-income community; surrounded by older, poorly-maintained appliances, people in these types of homes often breathe dirtier air indoors than outdoors. This is why Dr. Jackson proposes that the shift to clean energy be gradual; fueled by regulations and government support. Without social support, equal access to cleaner energy cannot be achieved.

In terms of major gas leaks, change is hard to make as an individual. According to the Environmental Defense Fund, the best thing we can do is to fight for national policy to repair and prevent leaks wherever they occur: whether at mining facilities or under our sidewalks. This is a difficult task, as all individuals can do is push for political action, however agreements such as the Global Methane Pledge seem to be steps in the right direction.

Across the United States, climate change is increasing the frequency and intensity of heat waves. A heat wave is defined as a persistent period of high temperature days. Although unusually hot days are a natural part of day-to-day variations in weather, heat waves are becoming more common alongside the rapidly accelerating climate crisis. In major cities across the country, the number of heat waves has increased steadily, from two heat waves per year in the 1960s to six per year into the 2010s and 2020s. In the 1960s, the average heat wave was 2.0 degrees above the local 85th percentile threshold, while the average heat wave during the 2020s has been 2.5 degrees above the local threshold. Approximately 210 million Americans, or two thirds of the population, live in counties vulnerable to health threats from high temperatures. As temperatures increase, the number of heat-related illnesses, emergency room visits, and deaths simultaneously increase. As we head further into the 21st century, adaptive measures to protect human health from the effects of extreme heat waves will be necessary in the face of rising climate risk.

Protecting yourself during extreme heat

Over the past three decades, heat waves have been the leading cause of weather-related fatalities across the nation. In addition to rising heat-related illnesses and deaths, extreme heat can also worsen health outcomes from chronic conditions such as cardiovascular disease, respiratory disease, and acute kidney injury. Extreme temperatures compromise the body’s ability to regulate its internal temperature, resulting in illness, heat cramps, heat exhaustion, heatstroke, and hyperthermia. Individuals living in densely populated cities are extremely vulnerable to the urban heat island effect, which exacerbates high heat temperatures as man made surfaces absorb sunlight during the day and radiate the stored energy at night as heat. Children, the elderly, people experiencing homelessness, low-income communities and individuals with pre-existing health conditions are at the greatest risk to the adverse effects of extreme heat. As temperatures continue to rise, it is necessary that individuals take on adaptive measures to protect themselves from the health risks posed by extreme heat. 

Action can be taken on both a policy and an individual level. Local governments can take steps to help residents reduce their vulnerability to heat through heat management plans and vulnerability assessments. For example, officials can create early warning systems and urban cooling centers for individuals to find refuge. On an individual scale, when you need to go outside, taking preventive measures such as sun protection, hats, and umbrellas is vital to stay cool. Trying to stay inside as much as possible and finding refuge from the heat will help one avoid the risks of heatstroke. More educational initiatives will be vital in informing individuals on risk factors, symptoms, and treatment steps to keep people safe and informed.

Benefits of protecting oneself during extreme heat 

During periods of extreme heat, it is important to take proper care of yourself in order to mitigate the health effects that result from high temperatures such as dehydration, heat stroke, exhaustion, and slowed cognitive function. Taking extreme heat seriously is vital, as the effects of extreme temperatures can be as serious as sudden events like heart attack or stroke. Prolonged periods of heat and humidity make your body work extra hard to maintain a normal temperature, so taking such precautions is necessary to protect yourself and your loved ones. As extreme heat-related weather events become more common, becoming accustomed to the ways you can keep yourself safe is imperative in a warming world.

More progress can be made

If we fail to take adaptation measures on both an individual and policy level, we will be unprepared to respond to the impacts of extreme heat. As extreme heat rises in prevalence, more awareness on the ways to respond to increasingly high temperatures can help individuals adapt to such events. Currently, heat is already the weather phenomenon that kills the most people in the United States, so taking care of yourself, family, and neighbors during heat waves is essential to saving lives. For residents who do not have the resources or cooling systems in place to seek protection during a heat wave, the use of cooling centers in cities can provide short-term relief. Important to note, however, is that the increased use of cooling systems will heighten electricity costs due to increasing demand, thereby generating more greenhouse gas emissions from rising power generation. If leaks are to occur, concerns can also arise around the potential release of potent refrigerant gasses, which worsen climate change and damage the ozone layer. This creates a self-perpetuating cycle in that air conditioning is used to treat extreme temperatures, but effectively worsens the climate crisis in doing so. More innovative solutions will be necessary to curtail emissions while keeping individuals safe. Beyond individual actions during times of crisis, cities also need to help their residents respond to rising temperatures in the long-term by redesigning public spaces, planting trees to provide cooling, painting rooftops white to repel sunlight, and incorporating new cooling technologies in buildings and homes.

The United States consumes vast amounts of energy and spends enormous amounts of money every year to fuel our economy, business, and lifestyle. The US accounts for 4% of the world’s population, yet uses 16% of the world’s total energy. The production and consumption of energy are major drivers of global climate change, hazardous air pollution, habitat destruction, and acid rain. In 2022, US consumers spent $1.7 trillion on energy, amounting to around 6.7% of GDP. Annual energy costs were $5,159 per person in 2022, a 30% increase from 2021. In order to mitigate the large-scale impacts of excessive energy consumption, policymakers are calling for an urgent restructuring of the energy system through increasing efficiency. Energy efficiency is the use of less energy to perform the same task or result, often being achieved through more efficient heating and cooling systems, manufacturing facilities, and appliances and electronics. Simply, energy efficiency reduces the amount of energy required to provide products and services. Many lower-income households are burdened by rising electricity costs and increasing risks from extreme weather events but do not have the resources to fund energy-efficient systems in their homes. To address this disparity, new energy efficiency standards for affordable housing are being developed in order to lower costs and improve climate resilience for households unable to afford high energy prices.

Current Initiatives in the US

The Biden Administration has taken a lead in issuing new minimum energy standards for homes built with federal dollars in an attempt to save costs for renters and homeowners. The US Department of Housing and Urban Development (HUD) and the USDA announced the adoption of the Minimum Energy Standards for new single and multi-family homes. The standards are expected to decrease cost expenditures for residents, reduce energy use and pollution, improve resident health, and increase resilience in extreme weather events. The adoption of such energy standards will incorporate cost-saving insulation, air sealing, and efficient windows, lighting, heating and cooling systems in HUD and USDA supported properties to decrease energy bills for families. It is projected that energy efficiency improvements of 37% will decrease energy costs by more than $950 a year for homeowners. Overall, minimum energy standards are projected to expand housing affordability, minimize health risks, and improve resilience of homes during extreme weather.

Advantages of energy efficiency standards

Energy efficiency can increase affordability and reliability for homeowners by reducing total energy demand and peak electricity demand. Peak electricity demand is the highest demand for electricity at any one point in time, which utilities are required to have the capacity to meet. Peak demand is driven by patterns of energy use in the market, with most production occurring in the afternoons. Energy efficiency programs utilize a demand-side management (DSM) strategy to reduce energy demand specifically during these high-volume, peak hours. For homeowners, energy efficiency improvements are cost-effective as they can lower utility bills by reducing the amount of power needed. Further, energy efficiency can decrease our reliance on fossil fuels and enable the growth of renewable energy, thereby decreasing GHG emissions. Updated minimum energy standards are expected to reduce 6.35 million metric tons in carbon emissions over the next three decades, generating an annual cost savings of $13.9 million. Energy efficiency also spurs the creation of new jobs in research, production, installation, and sales. In 2022, more than 2.1 million Americans worked in energy efficiency, with this only growing as we transition to a greener economy. There are many social, economic, and environmental advantages that come alongside transitioning towards an energy-efficient economy,

Drawbacks in achieving energy efficiency 

Although there are many advantages to achieving energy efficiency, there exists roadblocks in achieving the current goals being set. First, innovative technologies rely upon very specialized knowledge, requiring expert research in the field. As well, a large concern in the development of these technologies are the significant upfront costs, through initially high levels of investment in research and development. For projects that are just starting up, it can be difficult to secure funding, potentially leading businesses to solely focus on short-term goals. On the consumer side, there may be a lack of acceptance or awareness of these new technologies prohibiting their take up in the market. To achieve universal acceptance, technologies must attain the energy savings and functionality that consumers expect. Scaling up these technologies can be time-consuming and labor-intensive, requiring complex supply chain logistics, techniques, and manufacturing. Government policies, such as the new energy efficiency standards for lower-income households, will be vital in encouraging innovation and investment to accelerate this transition.

As climate change intensifies, the heightened frequency of natural disaster weather-related events is quickly becoming the new reality. Whether it be prolonged wildfire seasons in Northern California or destructive hurricanes off the Florida coast, citizens across the country are beginning to bear the burden of a changing climate. For those of us yet to experience the full force of such events, our primary means of gathering information on natural disasters is through the media. Without the media’s coverage of extreme climatic events, it is difficult for people not directly impacted to be fully aware of the dangers of a changing climate. While climate change impacts more people every year, severe impacts still feel like an abstract, distant concern that may never affect them personally. In order to reframe this perception, climate storytelling, which includes steps for action and recovery, is becoming foundational towards building empathy in the wake of the climate crisis.

What is Climate Journalism?

Climate journalism, the process of collecting and distributing accurate information on extreme weather events and climate change-related impacts, has been an essential element for informing the public about the effects of a changing climate. Following Al Gore’s 2006 documentary, An Inconvenient Truth, climate journalism increased by 1,000 percent in the media from the year 2000. This increase in viewership is most likely attributed to the rise of ethical concerns relating to the climate crisis as more people began to suffer the effects of natural disasters. The majority of Americans, approximately 54%, now identify climate change as a major threat to the country’s well-being. Media Matters found that news and morning shows such as ABC, CBS, NBC, and Fox spent a total of around 23 hours discussing climate change in their annual 2022 reporting. Unfortunately, climate coverage still only accounts for around 1% of corporate broadcasting, even though the climate crisis is rapidly worsening.

Keeping the Public Aware and Prepared

Climate journalism not only raises awareness for the public, but can provide steps for change in combating one of the most pressing issues of our time. People need accurate information in order to make informed decisions. Strong, reliable reporting can provide citizens and policymakers the information needed to prepare for and adapt to the potential impacts climate change brings. Climate journalism can offer hope to the public, providing people with the voice and power to make a difference. By including climate change in the media, people can begin to see the incoming reality of this crisis, inspiring citizens to take action.

The Struggles of Climate Coverage

Unfortunately, there remain many obstacles that hold back media organizations from prioritizing climate coverage. Climate-related disasters can be hard to access, difficult to watch, and politically polarizing. Media outlets may struggle to gain large viewership, deterring them from covering climate events. Further, the various approaches to climate journalism can create discrepancies in the type of media coverage disseminated. For example, should climate topics be covered locally or nationally? What solutions should climate journalism focus on? Such a broad scope may distract from the realities currently being faced. Unfortunately, media coverage of environmental issues still only occupies a very small proportion of total media. There remains a need for increased resources, strategies, and investment in climate and environmental journalism. Further, many major news outlets publish misleading promotional content for fossil fuel corporations, greatly impacting the opinions of viewers on such controversial issues. There are, of course, many examples of excellent climate change coverage.  Our modest effort at Climate Break, as a small example, focusing on climate solutions and the wide variety of actions and initiatives being developed around the world, is designed to provide quick insights into climate solutions.  

Who is Jonathan Vigliotti?

Jonathan Vigliotti, CBS News correspondent, is just one example of the many climate journalists directly involved in the movement to inform the public on the effects of climate change. Vigliotti’s work as an environmental journalist has taken him to over forty countries and territories across six continents. Author of Before It’s Gone: Stories from the Front Lines of Climate Change in Small-Town America, provides personal insights into the everyday lives of Americans affected by climate change, presenting a compelling argument for the urgency of taking action now. Vigliotti believes that climate journalism has the power to spark change through the use of accurate, inspiring, and thought-provoking reporting.

Technology and high-tech solutions are not the only responses to climate change. Nature can also be a powerful form of climate resilience. Resilience hotspots are small pockets of nature that, when restored and maintained, act as barriers to climate impacts. For instance, wetlands can insulate shores from storm surges and trees can provide shade in urban heat islands. In this way, climate adaptation can go hand-in-hand with integrating nature into our cities. 

The Science of Nature-Based Solutions

While many natural areas can have climate benefits, wetlands and urban green spaces are particularly significant ecosystems in terms of climate adaptation. How do these natural protections from climate change work in the first place? 

Wetlands are areas where the soil is saturated with water either seasonally or year-round. They often provide crucial protection from the heavy rainfall and storms, which are becoming more frequent and severe due to climate change. Acting as a sort of sponge, wetlands have the ability to absorb and temporarily store the excess water from these events. When a storm hits, wetlands are a “speed bump” to floodwaters, slowing and holding back storm surge and flooding that otherwise  causes damage to nearby cities and towns. According to NOAA, such protection by wetlands saves US coastal communities a whopping $23 billion a year. In many areas of the US, wetlands have been degraded by nearby urbanization or drained for development, leaving these areas more vulnerable to storm surge and flooding. As a result, restoring wetlands has become a priority as a strategy to increase climate resilience in these areas.

Urban green spaces protect against a different climate impact: extreme heat. Because urban surfaces tend to be densely covered in heat-absorbing materials like asphalt or concrete, cities absorb a greater proportion of heat from the sun’s rays. This, combined with greater concentrations of greenhouse gasses in cities, leads to a situation where cities can be up to 20 degrees Fahrenheit hotter than nearby green spaces, a phenomenon known as the urban heat island effect. With the temperature increases associated with climate change, the heat island effect poses great risks for heat-related illness and death. Urban green spaces break up the dense cover of manmade material with parks, green roofs, and shade-providing trees, creating natural areas that reflect sunlight, take up greenhouse gas emissions and provide aesthetic and mental health benefits. 

How to Build Resilience Hotspots

So how can we implement these nature-based climate solutions into our cities? The resilience hotspots approach uses a patchwork of crucial sites integrated into towns and communities. By focusing on places with great potential to mitigate climate damage, this approach promotes the benefits of nature-based solutions while working with the existing urban infrastructure. 

In the San Francisco Bay Area of California, for example, existing wetlands have the potential to store water and reduce storm surge during storm events if they are enhanced, thereby protecting a great number of low-lying urban places. Greenbelt Alliance has identified eighteen key areas across the Bay Area that have great natural potential to mitigate climate damages and are located in or near communities that will bear greater impacts from climate change. Working with community partners, they plan and implement restoration projects that enhance the ecosystem and increase resilience.  

Equity also plays an important role in designing resilience hotspots. A process that involves community organizations in the restoration of their environment integrates local expertise and insights and can promote equitable outcomes. By combining science and equity, restoration, equity and resilience can operate collectively. Resilience hotspots can be a natural tool for mitigating climate damages and for advancing climate justice.

Gas stoves have recently been in the news as a source of harmful pollutants in the home and generators of greenhouse gas. The adoption of energy-efficient induction-range stovetops could offer a solution. Induction cooktops use electromagnetism to generate heat from directly within cookware, preventing the levels of energy loss seen in conventional gas or electric cooktops. The U.S. Consumer Product Safety Commission is not coming for anybody’s gas stove, despite a recent frenzy over concerns of bans on gas stovetops, so cooks around the country can pick the stove tops of their choosing. But as a handful of journalists have pointed out, the notion that gas stove tops are better for cooking than electric, really a matter of opinion, could have something to do with advertising investments by the American Gas Association. In fact, many chefs actually prefer induction cooktops to gas, and their environmental benefits are substantial. 

Induction stoves contain an electromagnetic coil that generates a magnetic field when turned on. That magnetic field creates metallic resistance from compatible cookware, generating heat from within itself. Conversely, conventional gas and electric stoves transfer heat to pots and pans through a flame or electric coil. In that heat transfer, energy is lost. Induction has an energy efficiency of 85%. Electric stoves and gas stoves are 75-80% and 32% energy efficient, respectively, making gas the least energy efficient stove type. Across the United States, only about 32% of households use gas ranges, but in some states, like California, the number is closer to 70%. Energy Star estimates that a widespread shift to induction ranges would collectively save the United States over $125 million in energy costs and over 1000 GWh of energy.

Plug-in Induction-Range Stoves:

While Induction stoves are highly energy efficient, and can save consumers money on their energy bills, the upfront cost can be significant. According to Consumer Reports, a typical induction stove can range from roughly $1000 to $4000. Their installation can sometimes require upgrades to the home’s electrical wiring, which can add additional cost and complicates the process. Battery-powered induction-ranges like those in production by Channing Street Copper Company can be plugged in directly to standard electrical outlets. Plug-ins remove the complication of updating electrical panels or installing special high-voltage outlets, but they can be more expensive, costing consumers roughly $6000. However, a purchase of a standard induction or plug-in induction range may qualify consumers for rebates at federal and local levels.
