1:45How Climate Change Puts the Agriculture Industry at Risk 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. Who Is Our Guest? Tegan Nock is the Co-Founder and Chief Operating Officer of Loam Bio. A sixth-generation farmer from central west New South Wales, Australia, Nock combines her agricultural roots with a Bachelor of Science in Agriculture, Agriculture Operations, and Related Sciences from Charles Stuart University. In addition to her work at Loam Bio, Nock produced Grassroots: A Film About a Fungus , showcasing her passion for soil health and climate resilience. Featured in Netflix’s Down to Earth with Zac Efron (Season 2, Episode 8: Eco-Innovators ), Tegan shared insights on the seed treatment and the power of fungi to bolster stable carbon content in soil.

1:45What 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. About our guest Dr. Omar Yaghi is a professor of chemistry at the University of California Berkeley, and the Founding Director of the Berkeley Global Science Institute, whose mission is to build centers of research in developing countries and provide opportunities for young scholars to discover and learn. He is an elected member of the U.S. National Academy of Sciences as well as the German National Academy of Sciences Leopoldina.

1:44What is mechanical textile recycling? 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.

1:46What is Community Choice Aggregation? Community Choi ce 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.

1:45Climate Change and the Law of the Sea 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?

1:45Food Waste is a Global Problem with a Big Carbon Footprint 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.

1:44Steel Production 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. About the Guest Adam Rauwerdink is the Senior Vice President of Business Development for Boston Metal, a Massachusetts based start-up working towards decarbonizing steelmaking and advancing efficient, sustainable metal production.

1:45Mobilizing Investors to Build a More Sustainable Global Economy 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. Who is our guest?

1:45What is carbon mineralization? 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.

1:45Methane in the Atmosphere: A Serious Risk 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. Who is our guest?

1:45Impacts of Heat Waves on Human Health 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.

1:45The Current State of US Energy Consumption 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. Who is our guest? Mark Kresowik , Senior Policy Director at the American Council for an Energy-Efficient Economy, is a strong advocate for centering marginalized communities in policies that work to improve energy efficiency.

1:45Staying Educated About Climate Change 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.

1:44What are “Resilience Hotspots”? 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. About our Guest Sadie Wilson is the Director of Planning and Research at Greenbelt Alliance, where she manages resilience hotspots work and advocates for climate smart planning and policy. During her Masters in City and Regional Planning at UC Berkeley, she contributed to research at many Bay-Area focused institutions including the San Francisco Bay Conservation and Development Commission, The Center for Cities and Schools, and The Terner Center.

1:42Induction-Range Stoves: 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. Sam Calisch is an engineer and scientist working on decarbonization and electrification. He is the co-founder of Channing Street Copper, where he leads technology development.
