A Climate Change with Matt Matern

Today, Matt speaks with Frédéric Samama, adjunct professor at Sciences Po and author of The Enigma of Climate Inaction, about a simple question: if almost everyone knows about climate change, why aren’t we acting?

Fred, a pioneer of green finance, explains his idea of “societal bubbles.” Like a rat that learns its way to the cheese in a maze, humans got so good at getting resources through farming, capitalism and modern science that we became overconfident in the models that got us here. Now those same models are working against us, and climate c...

Today, Matt speaks with Mike Kelland, Co-founder & CEO of Planetary, about using the ocean to pull carbon dioxide out of the air. Planetary adds calcium and magnesium minerals, basically an antacid, to water flowing out of coastal facilities. That lowers local acidity and lets the ocean absorb more CO2 from the atmosphere.

Mike breaks down the UN's new Limiting Overshoot report, which he says puts the carbon removal we need at about 23 gigatons a year, and explains why trees, machines and every other land-based approach top out around 15, leaving the ocean to close the gap. He and...

Today, Matt speaks with Drew Shula, trained architect and Founder and CEO of Verdical Group, about the part of the climate problem hiding in plain sight: the buildings we live and work in, which account for roughly 40% of global carbon emissions. 

He breaks down the two halves of a building's carbon footprint, the energy it burns and the materials it's made of, and makes the case that we already know how to build net zero today - almost nothing requires it, which is why net zero is still less than 1% of construction. He and Matt also get i...

Today, Matt Matern speaks with Jim Murphy, Associate Vice President of Legal Advocacy at the National Wildlife Federation, about EPA's proposal to rewrite which streams and wetlands the Clean Water Act actually protects.

Jim explains what the rule would do - by his estimate, removing federal protection from up to 60% of the nation's stream miles and well over 90% of historically protected wetlands - and why streams that don't flow year-round still carry pollution downstream. He and Matt trace how we got here, from the Cuyahoga River fire and the 1972 Clean Water Act through the Supreme Court's 2023 decision...

Today, Matt Matern speaks with Rob Mullen - artist, author, and Director of the Wilderness River Expedition Art Fellowship - about the boreal forest, the largest land ecosystem on Earth and one most people have never heard of. Rob explains how a forest three times the size of the Amazon holds roughly 80% of the world's liquid fresh surface water, why bigger and more frequent fires have flipped it from a carbon sink into a carbon source, and how conservation funding passed it over for decades because it was too big and too empty to fit the "biodiversity hotspot" model.<...

Today, Matt Matern speaks with Leah Qusba, CEO of GoodPower, a nonprofit working to win public support for the clean energy transition. They talk about moving the energy conversation away from sacrifice and toward abundance, where clean energy means more jobs, lower bills, and an economy that works for everyone. Leah shares GoodPower's polling with NORC at the University of Chicago, which found about half of Republicans still support large-scale solar, rising to roughly 70% when it's tied to lower energy bills. They also dig into the disinformation targeting renewables, why one in three projects now dies in permitting, and...

Today, Matt is joined again by Cora Stryker, co-founder of Bright Saver. One year after first joining us on the show, a lot has changed. When she was last on, plug-in solar was legal in exactly one state and nobody in the country was selling it. Since then, 35 states plus DC have introduced legislation, nine have signed it into law, and Bright Saver has started shipping kits nationwide at exactly what they cost: $285.30, no markup. Here in California, SB 868 - the Plug and Play Solar Act - just cleared both houses of the legislature and is now sitting on...

Today, Matt is joined by Saar Safra, co-founder and CEO of Beewise, to talk about one of the quietest threats to our food supply - the collapse of the world's bee colonies. Saar shares how he teamed up with a commercial beekeeper to build the BeeHome: a solar-powered, AI-driven robotic hive that monitors bees around the clock and treats problems automatically, without chemicals. They dig into why bees pollinate roughly 75% of the crops we eat, how monoculture and pesticides have turned farmland into a desert for pollinators, and how Beewise has cut colony collapse from 40–60% down to under 10%. And Sa...

Today, Matt Matern speaks with Zak Winnick, founder and CEO of Rangeway Energy, about building America’s first hospitality-forward EV charging network. Zak shares how a career running hotels - and years of frustration as an EV owner - led him to treat charging as an experience rather than just a piece of infrastructure. They discuss why so many public chargers feel unreliable and impersonal, and how Rangeway is targeting the scenic, underserved highways the big networks skip. Zak also explains why the real money is in the amenities rather than the electricity - and how he plans to ma...

Today, Matt speaks with Bren Smith, co-founder and co-executive director of GreenWave, about his journey from commercial fisherman to pioneer of regenerative ocean farming. Bren shares how a cod collapse in his native Newfoundland and two hurricanes that destroyed his farm led him to a model that grows seaweed and shellfish with no water, fertilizer, feed, or land - while rebuilding ocean ecosystems. They also discuss GreenWave’s new State of the Kelp Industry report and how kelp is shifting from a “hero climate ingredient” to a working-class problem solver.

Today, Matt is joined by Dr. Garrett Boudinot, founder and CEO of Vycarb, to talk about a new approach to carbon capture and storage that works with water instead of pipelines and underground wells. Garrett explains how Vycarb's reactor turns CO2 into bicarbonate and stores it safely in the ocean for tens of thousands of years. He shares why traditional carbon capture has been so expensive and hard to site, and how Vycarb bypasses the costly steps to target costs as low as $50 a ton. He also previews what's next as Vycarb scales from its Brooklyn Navy Yard pilot...

Today, Matt is joined by David Fenton - veteran progressive communications strategist and host of The Fenton Forecast - for a conversation about the climate movement’s biggest failure: how it talks, or doesn’t talk, about the crisis. David explains “blanket of pollution” metaphor, and why framing climate action as sacrifice backfires, the soaring insurance costs hitting Americans’ wallets, and the fossil fuel industry’s push for legal immunity as climate lawsuits close in.

Today, Matt speaks with Tom Chi, founding partner of At One Ventures and a founding member of the Google X team behind Waymo, about using deep tech to restore ecosystems instead of just slowing the damage. 

They talk about the drone companies replanting mangroves, coral reefs, and seagrass beds, and how the cost of restoration keeps falling by half. Tom explains that a park ranger in 1926 had a Jeep, a map, binoculars, and a clicker, and today the tools are mostly the same. He also shares his concerns about who is steering AI right now, why regulation m...

Today, Matt speaks with Dr. Linley Dixon, Co-Director of the Real Organic Project and cohost of the Real Organic Podcast, about why how we grow food may be the climate lever we're ignoring. Linley explains that synthesizing nitrogen fertilizer alone accounts for 1-2% of the global carbon footprint. They also dig into what's gone wrong with the label people trust. Only about 1% of US farmland is certified organic while roughly 80% of our organic blueberries are imported, fraudulent "organic" grain shipments undercut American farmers, and the USDA allows soil-less hydroponics to carry the same seal as a soil farmer. 

Today, Matt speaks with Jeffrey Prosserman, CEO and co-founder of Voltpost, about a simple idea with big potential: turning the lampposts and utility poles cities already have into electric vehicle chargers. Jeffrey shares his path from leading product development at Samsung to founding Voltpost, and explains why more than 40% of Americans, those without a private garage or driveway, still can't conveniently charge an EV at home.

In this milestone 250th episode, Matt Matern goes solo for the final installment of our “250 for 250” series - tracing what the people who founded the country actually believed about land, soil, and stewardship. From Thomas Jefferson’s near-daily weather diary and George Washington’s soil-saving crop rotations, to the myth of endless abundance baked into the American character, Matt lays out what the founders left us: a genuine love of the land, and a dangerous belief that it could never run out.

This episode is part of our “250 for 250” series, marking America’s 250th anniversary by revisiting the figures an...

Today, Matt speaks with New York Times bestselling biographer Brian Jay Jones, author of Becoming Dr. Seuss and the new book The Capitol: The Surprising Biography of an American Building. Brian traces Theodor Geisel’s unlikely path - from advertising man to the most beloved children’s author in America. They dig into the making of The Lorax: the cookie-cutter condos eating up La Jolla’s coastline that made Seuss furious, the nine months of writer’s block, and the Kenya trip where he drafted the whole story in 90 minutes on the back of a notepad. Brian also shares the stor...

Today, Matt speaks with Philip Nel, University Distinguished Professor of English at Kansas State University and one of the world's leading Dr. Seuss scholars, about The Lorax and its place in the environmental movement. They trace the book's origins, from the coastal construction in La Jolla that made Seuss angry, to the trip to Kenya that finally unlocked the story he scribbled on a hotel laundry list. They also dig into the logging industry's counter-book Truax, why The Lorax keeps landing on banned-book lists, and how Lady Bird Johnson built an environmental campaign around it.

Today, no guest - just Matt, with the story of what one writer called “the best idea America ever had”: the national park. In 1872, in a country built on private property, the United States set aside Yellowstone as land that could never be owned by anyone - and then handed the idea to the world.

Matt traces how it happened: the writer John Muir and President Theodore Roosevelt, whose 1903 campfire in Yosemite helped put 230 million acres under protection; the birth of the National Park Service in 1916; and the system today - 433 sites, 85 million acres, owned in equal meas...

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.

Today, Matt is joined by environmental filmmaker Matt Podolsky, co-founder of Wild Lens Collective. They discuss the power of storytelling in the climate and conservation movement. Podolsky reflects on his Sundance-winning documentary Sea of Shadows, which chronicles the near-extinction of the vaquita due to illegal fishing, and his more recent work on bat populations threatened by white-nose syndrome. He also shares how conservation media can influence policy, protect ecosystems, and make invisible crises tangible to the public.
