    The Future of Battery Storage, with Dr. Shirley Meng

    Why Sodium? The global transition to renewable energy has accelerated the global development of lithium-ion batteries, but the mining and processing of its materials can be harmful to workers, local communities, and the environment. Sodium has a recently emerged as a potentially cheaper and more environmentally friendly alternative that could revolutionize battery storage systems. Dr. Shirley Meng is one of the scientists leading the way in this field, spearheading the creation of the world's first anode-free sodium solid-state battery.  Diving Deeper  Dr. Meng’s batteries have three key qualities: they are anode-free, sodium based, and solid-state. Though other researchers have developed batteries with similar characteristics, this is the first time all three have been combined.  Most batteries consist of three main parts: a cathode, anode, and electrolyte. The cathode is the positive pole, the anode is the negative pole, and the electrolyte is the material between the poles. As explained by the MIT School of Engineering, when a battery is connected to an external circuit, electrons move through the circuit, while simultaneously ions move through the electrolyte. The anode in a standard battery stores ions, while an anode-free battery starts out with no active anode material—the ions come entirely from the cathode. According to laser tech company Laserax, there is one key difference between Lithium-ion Batteries (LIBs) and Solid State Batteries (SSBs): the electrolyte material. In an LIB, this is a liquid, typically liquid salt dissolved in an organic solvent, which is highly flammable. In an SSB, this liquid is replaced by a solid electrolyte. Dr. Meng calls the electrolyte in her team’s batteries the “magic salt” because it’s primarily made out of sodium chloride - the same chemical as table salt. By supplementing the magic salt with other chemicals like oxygen, yttrium, and zirconia, an ion-conducting electrolyte can be formed.  The Pros and Cons  Dr. Meng’s batteries use sodium in place of the lithium in LIBs. Lithium and other LIB components can only be mined in particular regions, and production - besides being deleterious to the environment - is tightly controlled by a handful of powerful countries. Sodium, on the other hand, is predicted to be about 1200 times more plentiful than lithium in the earth’s crust, and can be accessed from other sources like sea water.  Anode-free batteries are often lighter, cheaper, and more energy-dense than similarly capable standard batteries. However, they can be harder to manufacture and can have shorter lifetimes. As advances are made by other researchers working on alternate battery structures, these challenges will likely be overcome, as have similar difficulties with LIBs. Dr. Meng’s batteries operate best in the lab at low external temperatures, which fills a gap in the battery market in extremely cold climates; however, scalability and widespread use demands that batteries function in a wide temperature range.  Solid-state batteries also come with a range of benefits and challenges. Besides being less flammable, they can have faster charging, higher energy capacity, and longer lifetimes compared to LIBs. However, they are susceptible to the formation of dendrites - or, tree-like metallic structures on the anode - which form during charging and can cause short circuits. Solid electrolytes are prone to cracking under mechanical stress, both in manufacturing and use. Like anode-free batteries and other cutting edge battery tech, SSBs have a long way to go in terms of scalability, but show promise in the future of battery development.  Dr. Meng’s Take Dr. Meng emphasizes that Sodium-ion battery technology is not new - research began back in the 1960s, but was outpaced by lithium-ion research, which at the time showed better results. Additionally, sodium batteries aren’t necessarily a replacement for lithium batteries, but rather a complementary technology that many companies will be able to produce without much capital investment. With the combination of these battery technologies, there is potential to moderate the cost of electricity at peak use times. Dr. Meng predicts that sodium-ion batteries may be able to compete with lithium-ion and lead-acid batteries in the next five years, and suggests that until then, costly but compact lithium batteries might be used in mobile applications, like computers, while sodium batteries - which for now are heavier - can be used for stationary purposes, like grid storage. Overall, she feels that it's “critical that all of us… stop temperature rise” - and sodium-ion batteries are a key step in the plan. About our guest Dr. Shirley Meng is the Liew Family Professor in Molecular Engineering at the Pritzker School of Molecular Engineering at the University of Chicago. She is also the Distinguished University Professor and Vice President (Industry) at Nanyang Technological University (NTU), Singapore. She directs the Energy Storage Research Alliance and is the principal investigator of the Laboratory for Energy Storage and Conversion (LESC) at UCSD.

    Making Cheese with Microbes, with Matt Gibson

    Introduction Mozzarella accounts for over 30% of all cheese produced in the U.S., more than any other variety. So when New Culture, a San Francisco-based food technology company, set out to remake vegan cheese, they started with the pizza topping millions of Americans know and love. New Culture, co-founded by guest Matt Gibson, relies on fermentation to make animal-free cheese that melts, stretches, and tastes like the real thing. Crucially, this process cuts down on the emissions, land, and water dairy farming requires.  Background Dairy production is a large driver of climate change. According to the BBC, cheese has the third-largest agricultural carbon footprint, after lamb and beef. Methane released by cows, sheep, and goats is a major contributor, along with the land and water needed to raise the animals. The process of cheesemaking multiplies this carbon footprint: it takes roughly ten pounds of milk to produce a single pound of cheese, meaning the carbon emissions of cheese are concentrated tenfold. New Culture sidesteps both livestock and the plant-based substitutes that have tried to replace them by manufacturing casein– the protein responsible for cheese’s stretch and gooeyness. As Gibson explains, the company trains microbes to produce casein inside fermentation tanks, similar to the process used to brew beer. The microbes feed on sugars to produce casein, and that protein is then combined with plant-based fats to create the finished cheese. This method, known as precision fermentation, dates back to the 1970s, when researchers first used E. coli to produce human insulin. Advantages According to Gibson, switching from dairy to New Culture’s cheese cuts greenhouse gas emissions by roughly 86%, with a 97% reduction in land use and a 98% reduction in water use.  Perhaps equally as important, New Culture doesn’t ask consumers to compromise on taste or texture. The manufactured casein is molecularly identical to what’s found in dairy milk, meaning that the cheese melts the way people expect. This is something most conventional plant-based cheeses, which lack casein entirely, have not been able to replicate. The switch from dairy cheese to an alternative, then, is now potentially more palatable. Drawbacks and Critiques Producing precision-fermented proteins is significantly more expensive than regular dairy products. Gibson acknowledges this, explaining that dairy is a heavily subsidized industry, and New Culture’s casein protein is the most expensive part of its cheese. The company has had to engineer ways to use less protein per product without sacrificing quality to stay competitive. He also points to the challenge of limited fermentation tanks and infrastructure. And it’s worth noting that the same trait that makes New Culture’s cheese taste like the real thing also carries a drawback. Because its casein is identical to the casein found in ruminant milk, someone with a milk allergy would still react to the cheese, even though no animal was involved in making it. This distinction could complicate how the product gets marketed and understood, since “animal-free” doesn’t necessarily equate to “dairy-free.” The Guest’s Take Gibson believes that “taste is king in the food world,” and because New Culture’s cheese is “indistinguishable to dairy cheese,” consumers aren’t giving anything up on the experience. He’s hopeful that as New Culture grows, costs will lower and its products will be adopted by mass-market restaurant chains where climate impact could be the greatest. For now, you can get a taste of New Culture mozzarella at partner restaurants like Pizzeria Mozza in LA.  About the Guest Matt Gibson is the Co-Founder and Chief Executive Officer of New Culture. He holds a Bachelor of Science in genetics and microbiology from the University of Auckland in his native New Zealand. Before co-founding New Culture, Gibson went vegan out of concern for the environmental and animal welfare impacts of dairy production.  Other Resources & Further Reading New Culture Website: New Culture The Good Food Institute Europe: The History of Precision Fermentation Vegpreneur: Matt Gibson’s Biography

    Building a Climate Workforce, with Julia Hatton

    Introduction As California works to reduce greenhouse gas emissions from buildings, the transition to energy-efficient homes is an important opportunity for climate careers. The Rising Sun Center for Opportunity, a California-based nonprofit managed by Julia Hatton, helps address challenges faced by those in underserved communities when it comes to job training. Through hands-on programs, participants can gain valuable skills as they work to improve green buildings. Background Buildings account for over 40% of the global energy consumption and carbon emissions, making improvements to the energy and water efficiency of local homes an important part of climate strategy. As a result, the transition to clean energy creates a high demand for workers trained in energy efficiency and green construction—and there is a global shortage of workers with the applicable skills.  The Rising Sun Center for Opportunity assists not only with the immediate need, but also in building career pathways focused on long-term climate resilience. By employing young people from low-income backgrounds in the Bay and Central California, this nonprofit works as a launchpad for future climate action. Advantages Climate job training addresses both economic and environmental challenges simultaneously. Participants gain practical skills to help them enter the green industry, while households can receive services that save energy and water.  The hands-on approach that the Rising Sun Center for Opportunity utilizes furthers this endeavor, especially with the focus it has on leveling the playing field. With programs specializing in preparing youth, women, and individuals in reentry, a diverse range of participants can work directly in homes and communities. This provides immediate climate benefits to recipients of service, while workers gain experience in real-world projects that equip them with skills necessary for a long-term career. Drawbacks and Critiques Some contend that climate job training doesn’t always translate into long-term climate employment. Although the Rising Sun Center for Opportunity may provide an efficient starting point, participants are not guaranteed a green career, especially if employers require other additional experiences or skills.  There is also a need to ensure that the climate transition doesn’t just create jobs; it should also help establish economic power for those who have been marginalized from careers, as Hatton emphasizes. Although the Rising Sun Center for Opportunity aims to coordinate efforts from a wide group of historically disadvantaged communities, it’s crucial that efforts translate into real impact. The Guest’s Take Ms. Julia Hatton believes that investment in workers in green jobs is crucial to advance response to climate change. Rather than identifying job creation and reducing emissions as separate goals, Hatton sees potential in merging and combating both actions at once: by allowing them to reinforce each other. About the Guest Ms. Julia Hatton is the President & Chief Executive Officer at Rising Sun Center for Opportunity, committed to climate job training for underserved communities to lead climate action. She takes charge in leading innovation in the workforce and climate sector alike.

    Recycling Solar Panels, with Pablo Dias

    The Global Transition As the global transition to clean energy accelerates, scaling solar infrastructure has emerged as one of the most critical pathways to achieving a net-zero future. However, this rapid buildout could bring an increasingly large amount of waste as solar panels reach their end of life. To avoid this, recycling offers a dual climate solution: it significantly reduces the greenhouse gas emissions associated with primary mining and provides a supply of pre-refined, low-carbon materials that can be used to make new panels.  The Role of Solar Panels Transitioning away from fossil fuels and achieving net-zero carbon emissions at a global scale requires rapid deployment of renewable technologies. For solar energy specifically, the amount of solar infrastructure needed on Earth to meet climate goals is about 16 times what has already been built. This buildout demands large quantities of raw materials, including glass, silica sand, silver, copper, and aluminum. While these resources are traditionally mined from the Earth, they can also be recovered directly from solar panels once they reach their end-of-life. Extracting and processing raw materials for solar panels through primary mining is resource-intensive, and recycling those materials significantly reduces the panels’ manufacturing emissions. Similarly, integrating recycled solar glass cullet into manufacturing lowers furnace operating temperatures, cutting energy consumption by 2.5% to 3% for every 10% of cullet added and reducing the overall energy and emissions needed to produce new glass. If solar panels are taken to traditional e-waste recycling facilities, these sites typically rely on bulk shredding, a process that destroys material purity and scatters valuable metals. In contrast, the solar recycling process from SOLARCYCLE uses a step-by-step “reverse manufacturing” sequence in which the company strips away the junction box, removes the aluminum frame, and isolates the specialized glass to recover up to 97% of a panel’s material value. Furthermore, because solar manufacturing has evolved to generate more energy using fewer materials, the elements recovered from decommissioned panels can be the basis to build newer, higher-efficiency arrays that generate even more clean power. The Impact on Energy and Raw Materials Solar panel recycling requires dramatically less energy input, potentially avoiding up to 95% of the CO2 emissions and 95% of the energy needed to mine and process raw aluminum for new solar panels. What’s more, this technology can recover up to 99% or more of key materials like glass and metals. Likewise, because this solution recovers critical resources like silver and copper from existing infrastructure, the technology can be used to mine materials from what has already been produced and collected rather than extracting new minerals from the Earth. This means the technology has the potential to eliminate up to 25% of manufacturing emissions for specialized solar glass, while diverting toxic chemicals like lead and cadmium away from landfills to protect environmental and human health. Challenges: Recyclability and Economics  Currently,  panels have not been designed for recyclability, making the process of separating their tightly sealed layers a technical challenge. Because solar manufacturers operate on very thin or negative profit margins, they have rarely prioritized design-for-recyclability features, leaving decades of panels that will need specialized, intensive processing when they decommission. Scaling this technology also presents operational challenges because, while recycling thousands of panels is manageable, processing the millions of units at scale will require tooling that a supporting industry cannot yet provide. Solar panel recycling currently struggles to compete economically with traditional waste disposal depending on local geography. In countries like the United States, landfill remains the cheaper option, creating a financial gap that can deter asset owners from recycling the panels. Moreover, the process cannot yet achieve a fully circular loop for all components. Certain materials, like thermoset plastics, are unrecyclable and must be diverted to waste-to-energy processes. Finally, the industry faces regulatory risks from “sham recycling”, where bad actors take upfront payments but fail to manage the materials properly, creating an environmental hazard by exposing toxic lead or cadmium to the soil. The Guest’s Take Pablo Dias sees solar panel recycling as an essential part of the energy transition. For him, this process closes the loop on a true circular economy by allowing discarded panels to be mined for valuable resources like aluminum, silver, and copper instead of extracting raw materials from the Earth. This is part of a broader vision for a waste-free solar industry, turning end-of-life solar panels into a tool to drastically reduce the industry’s emissions and eliminate the environmental and social risks of heavy metal leaching.

    Approaching Climate Change Through Tribal Stewardship, with Geneva EB Thompson

    What is TEK? As climate change increases the frequency and severity of extreme weather events, traditional land and water management approaches are proving insufficient to protect ecosystems and communities. Restoring tribal stewardship by re-establishing Indigenous leadership, returning ancestral lands, and applying Traditional Ecological Knowledge (TEK) offers a holistic climate solution. By working with nature through practices like cultural fires, wetland restoration, and natural carbon capture, tribal stewardship builds ecosystem resilience, reduces wildfire and flood risks, and enhances natural carbon sequestration across California.   How We Got Here Before European colonization, Native communities managed California’s ecosystems for millennia through practices rooted in place-based TEK. Settler colonialism displaced those communities and severed TEK from ecosystem management. In California, this included the criminalization of cultural burning practices and the non-ratification of 18 negotiated federal treaties in the 1850s, which broke promises to reserve 7.5 million acres of permanent tribal homelands. Decades of fire suppression and environmental degradation have left forests overgrown with dry biomass and ecosystems vulnerable to hazards such as severe wildfires, flooding, and biodiversity loss.   What Now? To begin addressing these historical wrongs and build climate resilience, in March of 2026 the California Natural Resources Agency launched a policy aimed at restoring meaningful tribal stewardship across at least 7.5 million acres of land and coastal waters. The policy outlines three pathways:  Ancestral land return — land acquisitions by Native communities through state grants and land trust partnerships, Co-Management and collaboration — shared or delegated decision-making power between tribal and non-tribal entities for joint conservation, and Durable tribal access — removal of legal and administrative barriers so Native cultural practitioners can access ancestral territories. Advantages The main advantage of tribal stewardship is its ability to proactively mitigate extreme climate risks and restore ecosystems. Low-intensity cultural burning clears out woody biomass and dry plant material, preventing severe fuel buildup and slowing down catastrophic wildfires. In water ecosystems, restoring native wetland species like tule beds slows down floodwaters, enhances groundwater infiltration, and stabilizes freshwater ecosystems. Similarly, restoration of coastal kelp forests protects critical natural carbon sinks while cooling ocean waters. Likewise, facilitating tribal stewardship can promote Indigenous-led initiatives such as clean energy microgrids, which can provide surrounding rural communities with emergency power, shelter, and resources during climate-induced disasters. Ultimately, grounding land return targets in historical treaty obligations takes concrete, tangible steps toward truth, healing, and repairing historical injustices committed against Native communities.   Drawbacks  A current constraint of implementing tribal stewardship at scale is the ongoing challenge of securing durable, long-term funding for land reacquisition and management, especially when relying on fluctuating state budget cycles or bond measures. Negotiating co-management agreements also presents deep administrative challenges, as navigating complex, siloed legal structures across federal, state, local, and private landowning entities requires significant time and institutional coordination. Additionally, given that landscapes have suffered from severe degradation and artificial fire suppression, safely reintroducing controlled cultural practices requires intensive labor, resources, and careful planning to avoid runaway risks in overgrown forests. Finally, non-tribal government entities often struggle to integrate traditional knowledge because they aren’t designed to blend Indigenous expertise with their laws and policies.    The Guest’s Take Geneva EB Thompson views tribal stewardship not only as a conservation strategy, but as an essential framework for climate resilience and environmental justice. For her, empowering tribes to steward land and water ecosystems creates a positive ripple effect that yields healthier, safer, and more resilient communities for all Californians. She emphasizes that all of California is ancestral Indigenous territory, and that centering Native leadership and place-based expertise in ecosystem management is vital for addressing interconnected climate hazards.   About the Guest Geneva EB Thompson is the Deputy Secretary for Tribal Affairs at the California Natural Resources Agency.    Further Reading California Natural Resources Agency – Tribal Stewardship Policy Sierra Club – Indigenous Co-Stewardship Policy & Guidance  Popular Science – How tribal co-managing movements are transforming the conservation of public lands Indigenous Land & Data Stewards Lab – Resource Hub  The Nature Conservancy – Partnering with Indigenous Peoples and Local Communities National Park Service – Indigenous Fire Practices Shape Our Land For a transcript, please visit https://climatebreak.org/approaching-climate-change-through-tribal-stewardship-with-geneva-eb-thompson/

    Green Tech Hubs: Scaling Climate Technology Startups

    Introduction to Green Tech Hubs Small green tech startups often possess groundbreaking ideas to combat climate issues, but lack the market resources, capital, and visibility to make large-scale impact. However, the Hong Kong Science and Technology Parks Corporation (HKSTP) Green Tech Hub is taking initiative for a change. By creating connected workspaces and acting as a launchpad for startups, the hub fosters more collaborative and impactful climate innovation. Background A physical community of more than 230 companies with work stretching across new energy, smart cities, green buildings, and green fintech are changing the equation. The green tech hub co-locates companies with similar goals, facilitates business matchmaking, and offers hands-on training to attract investors. In this way, the global transition towards sustainable technology is accelerated through a joint effort.  Advantages The hub acts as a bridge between small companies’ operational struggles and their passion, ambition, and goals. By equipping green innovators with the network, visibility, and skills necessary to expand, green tech hubs help these startups overcome market challenges. Green tech hubs also promote businesses’ climate-friendly products for targeted marketing, especially overseas, connecting innovators with potential clients and investors. In addition, the mentorship program assists in product design to better suit the market. Globally, as green tech reaches the market, the hope is that it will replace climate-harming technology, taking advantage of the close proximity of innovators thereby promoting the transfer of knowledge. Across networks, founders can promote the best products to be implemented on a wide scale. Because Hong Kong is ranked as the #1 freest economy in the world and #2 for enterprise conditions, green tech hubs can benefit from this gateway for technological innovation and expansion with the right tools. These hubs are becoming increasingly crucial to a sustainable world as the urgency to address environmental degradation grows. Drawbacks and Critiques A potential drawback to green tech hubs is the fact it’s a public-private partnership between Hong Kong’s government and companies. Being tied to the government exposes the hubs to swings in government decisions, policies, and goals. Without proper design or understanding for the entrepreneurial process, governments struggle to balance their positions as catalysts with limited control in entrepreneurship. Some economists also argue against the model that green tech hubs possess: the “cluster,” where similar businesses are grouped together—especially for startups. New, small companies may thrive better within highly diverse environments, exposing innovators to different products, models, and fields, rather than being limited to counterparts of similar technologies and goals. The Guest’s Take For Mr. Howard Lee, green tech hubs are a way to change the equation—allowing small innovators to effectively combat climate issues with sufficient magnitude. To displace climate-harming technologies on a global scale, Mr. Lee emphasizes the importance of inspiration and creativity that results from collaboration among passionate changemakers. About the Guest Mr. Howard Lee is the associate director of Hong Kong’s green technology hub at Hong Kong Science and Technology Parks Corporation, aiming to connect scientific and technological knowledge with stakeholders to accelerate green innovation. With a public-private partnership between the Hong Kong government and businesses/investors, Mr. Lee focuses on promoting climate-friendly companies through green tech hubs.

    Building Berkeley’s Clean Energy Campus, with Sally McGarrahan

    A Clean Energy Campus In July 2025, the University of California Board of Regents approved a plan to modernize UC Berkeley’s energy infrastructure by replacing its aged steam system with efficient, all-electric heating and cooling systems.  Today, 90% of Berkeley’s power comes from the combustion of natural gas at UC Berkeley’s costly and outdated fossil gas cogeneration plant. However, the plant is nearing the end of its life: it has less than a decade of life left, and is a source of frequent, costly, and disruptive repairs on campus (UC Berkeley Clean Energy Campus). In an effort to build a more sustainable future, the plan seeks to phase out fossil fuel use for powering, heating, and cooling campus buildings by 2035 or sooner. Advantages The plan is primarily funded by a capital investment from the State of California, and will be conducted in 3 phases. Phase 1, which will take place from mid-2026 through 2030, will electrify Berkeley’s heating and cooling plant, upgrade electrical infrastructure, improve thermal energy storage, distribute heated and chilled water through an underground system, and update the accessibility of landscaping and pathways on campus (UC Berkeley Clean Energy Campus). The plan not only predicts a 70% reduction in carbon emissions from campus buildings by 2028 and a 59% reduction in campus-wide greenhouse gas emissions by 2035 and promotion of energy resilience, but also promises to create new employment and training opportunities, distributing the benefits of clean energy across the campus and the local community (CEC First Phase Underway). The project’s primary priority is the establishment of an Electrified Heating and Cooling Plant (EHCP). The new system, rather than relying on steam and natural gas, will develop a fully functional clean energy microgrid. A major component of this includes a “new central electrified heating and cooling plant capable of serving more than 12 million square feet of building space,” located underneath a new recreational field (CEC First Phase Underway). The plant functions primarily through a “geothermal” mechanism: an underground heat exchange will distribute hot and chilled water throughout campus to heat and cool buildings (Berkeley Energy and Resources Collaborative).  UC Berkeley is not alone in its goals to phase out fossil fuels — both UC Davis and UC Santa Cruz — are making similar long-term plans for transitioning to renewable energy sources (University of California). Each of the individual campus’ goals align with the UC system’s new climate policy, which aims to eliminate greenhouse gas emissions across all ten campuses by 2045 (University of California).  Drawbacks While the plan would undoubtedly make strides in UC Berkeley’s plans to reduce their carbon footprint, its success is not guaranteed. Of the $700 million required to complete the plan, UC Berkeley has currently secured $270 million (Cal Alumni Association). In order to ensure the project is seen through, pressure on campus leadership and the State of California to maintain continued funding is critical. About our guest Sally McGarrahan oversees the Berkeley Clean Energy Campus Project at UC Berkeley’s Office of Facility Services.

    Rerun: Staying Safe in Extreme Heat, with Dr. David Sklar

    Impacts 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.  About our guest Dr. David Sklar is an Assistant Dean at the Arizona State University School of Medicine and Advanced Medical Engineering, is a Professor at the ASU College of Health Solutions and works as an emergency physician. Former Editor in Chief of Academic Medicine, Dr. Sklar now works as a senior advisor in health policy and health professions education at ASU Health.
