A Climate Change with Matt Matern

Today, Matt speaks with Micah Loewinger, co-host of WNYC’s On the Media and the reporter behind the new four-part series American Emergency: The Movement to Kill FEMA, about how the agency built to respond to America’s worst disasters became one of its least trusted institutions. Micah explains how he came to FEMA through years of covering far-right militias, why the “FEMA camps” conspiracy theory traces back to the Cold War, and how it disturbingly echoes in today’s migrant detention programs. They dig into the contrast between Hurricane Katrina - a genuine failure that defined FEMA’s reputation...

Today, no guest - just Matt, telling one of the strangest and most hopeful stories in American politics. It's the story of the first Earth Day, when 20 million Americans - about one in ten of the entire country - took to the streets on a single day in April 1970, and changed the course of the nation in just two years.

Matt traces how that one day produced the EPA, the Clean Air Act, and the Clean Water Act - and uncovers the part most people have forgotten: nearly all of it happened with overwhelming support from both...

Today, Matt speaks with Jonathan Criss, CEO and co-founder of Vital Lyfe, about reinventing how the world gets clean drinking water. After 13 years at SpaceX working on the Starlink and Dragon programs, Jonathan set out to apply the same first-principles engineering to desalination - starting with a unit he built in his garage that cleaned ocean water. They talk about why the water crisis is really an infrastructure problem rather than a scarcity one, how Vital Lyfe’s portable “Access” device makes drinking water from nearly any natural source without the energy and problems of big desalination plants, and where...

Today, Matt speaks with Dean Forgeron, Chief Technology Officer at CarbonCure Technologies, about the Halifax-based clean tech company decarbonizing one of the world's most polluting industries. Dean explains the chemistry behind injecting CO2 into concrete - where it permanently mineralizes into calcium carbonate, the same material as limestone, while reducing cement use by roughly 4.5% on average. They discuss CarbonCure's recent milestone of 11 million truckloads of low-carbon concrete produced (~768,000 metric tons of CO2 stored), the company's 2026 CleanTech Breakthrough Award, and how the industry is shifting from offsetting to insetting - modifying supply chains to actually reduce emissions at the source.<...

Today, Matt is joined by Dan Miller - Managing Director of The Roda Group and host of Climate Chat on YouTube - for a wide-ranging conversation on the economics of the energy transition and the 2026 race for California Governor. Dan explains why renewables are already cheaper than fossil fuels (a Harvard study attributes 8 million deaths a year to fossil fuel pollution), why EVs will replace gas cars the same way cars replaced horses, the $7 trillion governments still spend each year subsidizing fossil fuels, and why AI's energy hunger is one of the biggest threats to climate progress. Dan also...

Today, Matt speaks with Ibhade Eigbobo, Director of Corporate Project Management at Budderfly, about why the small and midsize business sector is one of America's most underused energy assets. Ibhade explains Budderfly's energy-as-a-service model - where the company takes over a customer's entire utility bill, invests its own capital to upgrade aging equipment, and earns revenue as a share of the savings. They cover why quick service restaurants are the most energy-dense buildings in the country, how batteries and virtual power plants turn small sites into grid assets, and why Ibhade believes efficiency has to come before any large-scale...

Today, Matt is joined by Brett Jenks, CEO of Rare, a global conservation nonprofit that helps coastal fishing communities, smallholder farmers, and local leaders in 60+ countries build climate resilience through behavioral science and community-led solutions. Brett shares how Rare's Fish Forever program grew from three pilot communities in the Philippines to more than 2,000 communities across Indonesia, Brazil, Mozambique, the Bahamas, and beyond - putting 4 million hectares of the world's most biodiverse coastal ocean under sustainable management.

They discuss why climate adaptation has been underfunded for decades, why Bill Gates got it wrong in his recent climate memo...

Today, Matt speaks with Marci Zaroff - founder of ECOfashion Corp and one of the pioneers of the sustainable fashion movement - about the real cost of what we wear. They cover how 60% of the cotton plant ends up in our food supply, why organic and regenerative fibers matter for human health, the difference between greenwashing and genuine certification, and how the industry is shifting toward traceability and outcome-based standards. Marci also shares how she helped build the Global Organic Textile Standard (GOTS), what ECOfashion Corp is doing today with artists like Billie Eilish, and why she sees this...

Today, Matt speaks with Annie Leonard and André Carothers, co-authors of Protest: Respect It, Defend It, Use It, published by Patagonia Books. Annie is the creator of The Story of Stuff and former Executive Director of Greenpeace USA. André is a four-decade activist and co-founder of the Rockwood Leadership Institute.

They discuss why peaceful protest is foundational to democracy - and how it's under unprecedented attack. They break down the surge of anti-protest laws across 49 states, the fossil fuel industry's use of SLAPP suits to bankrupt activist groups (including a $660 million verdict against Greenpeace), and what it me...

Today, Matt speaks with Doug Weir, Director at the Conflict and Environment Observatory (CEOBS), about the environmental toll of armed conflict - and why it rarely gets the attention it deserves. They cover CEOBS’s real-time tracking of 300+ environmental incidents from the Iran war, including the Tehran oil fires and threats to the Persian Gulf’s fragile marine ecosystems. Doug also explains how rising military budgets are quietly undermining global climate progress, why the “military emissions gap” is a major blind spot in international climate accounting, and what it would take to hold governments accountable for environmental destruction.

Today, Matt speaks with Peter Reinhardt, co-founder and CEO of Charm Industrial, about one of the most ambitious bets in climate tech: putting carbon back underground permanently. Peter explains how Charm takes wood from wildfire thinning projects in the Colorado Rockies, converts it into bio-oil through a process called pyrolysis, and injects that carbon-rich liquid deep into sandstone formations in Louisiana — where it stays for millennia. They discuss the cost curve challenge, why most carbon offsets are ineffective, what it actually takes to scale carbon removal, and the bipartisan legislation that could unlock wildfire biomass as a climate solution. Pe...

Today, Matt checks back in with Michelle Moore, CEO of Groundswell and author of Rural Renaissance, nearly a year after the EPA canceled Groundswell's $156 million Solar for All contract. Michelle shares how Groundswell is pressing forward anyway, building a new financing model around corporate off-takers and utility partnerships to keep 20MW of community solar alive. They also dig into the full-blown energy crisis hitting American families at the kitchen table - electricity bills up over 10%, AI data centers driving unprecedented demand, and a federal government that has largely stepped out of the affordability business. Michelle says the renaissance in...

Note: This episode was recorded on March 23, 2026. The situation is fast-moving — some details may have evolved, but the underlying story hasn't.

Today, Matt speaks with award-winning investigative journalist Miranda Green about the fossil fuel dimensions of the U.S.-Iran conflict. Miranda - author of The Understory, Atmos Magazine's weekly climate-culture newsletter - traces how the conflict has disrupted roughly 20% of the world's liquid natural gas and oil flowing through the Strait of Hormuz, sent gas prices surging past $7 a gallon in parts of California, and exposed just how deeply the global economy remains dependent on...

Today, Matt speaks with Nathaniel Stinnett, returning guest and Founder and Executive Director of the Environmental Voter Project (EVP), about the climate movement’s political power problem. Nathaniel explains why tens of millions of environmentalists don’t vote — and why the number one answer people give for how to address the climate crisis is recycling. He shares how EVP uses predictive modeling, randomized control trials, and behavioral psychology tools like peer pressure and endowed progress to turn non-voters into habitual voters. They also look ahead to the 2026 midterms, where EVP is targeting 3.4 million first-time climate voters across 21 states.

Today, Matt speaks with Katie Surma, reporter at Inside Climate News and one of the world’s leading journalists covering the rights of nature movement. Katie has covered the movement across four continents, and in this conversation she and Matt take stock of where things stand: the wins, the rollbacks, and the road ahead.

They discuss the groundbreaking Indigenous-led treaty recognizing whales’ rights in New Zealand, scientists using AI to decode sperm whale language, and how Ecuador’s constitutional rights of nature have survived repeated political attacks. They also dig into why rights of nature laws ke...

Today, Matt speaks with award-winning journalist and author Michael Grunwald about his new book, We Are Eating the Earth: The Race to Fix Our Food System and Save Our Climate. Grunwald makes the case that food and land use are responsible for roughly a third of global greenhouse gas emissions — a massive blind spot in most climate conversations. They discuss why the world is on track to eat 70% more meat by 2050, the limits of veganism and organic farming as climate strategies, and why Denmark’s 2025 agricultural policy may be the most important climate legislation most people have never heard of...

Today, Matt speaks with Jennifer Pitt, Colorado River Program Director at the National Audubon Society, about the deepening water crisis facing the American West. Jennifer explains how the Colorado River's reservoirs — once full just 25 years ago — now sit at roughly one-third capacity, and why the expiration of the existing water management agreements at the end of 2026 creates an urgent governance challenge. They discuss the role of irrigated agriculture in consuming 80% of the river's water, the politics of voluntary water buyback programs, and why seven states must reach consensus before the federal government is left with blunt tools and the risk...

Today, Matt Matern speaks with Amelia Southern-Uribe, Director of Global Organizing at Zero Hour, about building youth-led climate power in the American South. Amelia shares how frontline communities shaped their activism and how organizing, storytelling, and coalition-building drive change.
