375: This CDR Marketplace Bought a Biochar Company. Now What?!—w/ Josiah Hunt of Pacific Biochar & Sophie Westover of Wren
Wren recently purchased a majority stake in Pacific Biochar, one of carbon removal's most prolific credit deliverers. What led to this deal, and will this model be emulated in a 2026 that might find carbon removal companies interested in (or maybe desperate for) deals that prolong runway and keep their companies alive?Wren is one of the oldest marketplaces (and so much more) in carbon removal with a record of doing things differently. Sophie Westover is their Head of Climate and is on the show representing their thinking on this deal.Josiah Hunt is the Founder and CEO of Pacific Biochar. He's been making biochar since before most of us knew it was a thing. He shares a lot of realness about the difficulties of being a project developer—even a successful one—in carbon removal.This Episode's SponsorsAbsolute Climate: the only standard that’s developed independent of registriesPhilip Lee LLP: legal resources for carbon removal buyers and suppliersListen to the RCC episode with Peter Minor from Absolute ClimateListen to the RCC episode with Ryan Covington from Philip Lee LLPBecome a sponsor by emailing carbon.removal.strategies[at]gmail.comSign up for the 9Zero climate coworking space with my referral codeResourcesBecome a paid subscriber of Reversing Climate ChangeSubscribe to the Reversing Climate Change SubstackWrenPacific Biochar"Wren proudly invests in Pacific Biochar to scale carbon removal"In case you want to see Pacific Biochar on the cdr.fyi supplier leaderboard.Benefit corporationKita"313: Can carbon removal be insured?—w/ Racheal Notto & James Kench, Kita"

374: Mining with Microbes: Biomimicry in Copper Extraction—w/ Liz Dennett, PhD, CEO & Founder of Endolith
What if microbes could help us mine responsibly? What if astrobiology—the study of life beyond Earth—held clues for how to fix the way we extract resources on Earth?Today’s guest is Liz Dennett, CEO and founder of Endolith, a biotech startup using microbes to boost copper recovery from mining waste. With a PhD in astrobiology, experience at NASA, and a career spanning oil, gas, and data science, Dennett is one of the most fascinating polymaths in climate tech.This episode dives into how microbes mine metals, why copper is civilization’s next constraint, and what it means to clean up an industry everyone loves to hate. Ross and Liz also explore the moral contradictions of “ethical extraction,” the realities of startup life, and how humor—and humility—might be the best renewable resources of all.This Episode's SponsorsAbsolute Climate: the only standard that’s developed independent of registriesPhilip Lee LLP: legal resources for carbon removal buyers and suppliersListen to the RCC episode with Peter Minor from Absolute ClimateListen to the RCC episode with Ryan Covington from Philip Lee LLPBecome a sponsor by emailing carbon.removal.strategies[at]gmail.comUse this affiliate link to use Descript's transcripting and podcast editing serviceSign up for the 9Zero climate coworking space with my referral codeResourcesBecome a paid subscriber of Reversing Climate ChangeSubscribe to the Reversing Climate Change SubstackEndolith's websiteEarth in Human Hands: Shaping Our Planet's Future by Dr. David Grinspoon47: David Grinspoon, AstrobiologistGeology Cage Match: The Sapiezoic vs. the AnthropoceneBill NyeEukaryogenesisAbiogenesisEntropyCobalt Red: How the Blood of the Congo Powers Our Lives by Siddharth KaraThe War BelowLithium, Copper, and the Global Battle to Power Our Lives by Ernest ScheyderDeus ex machina“If it falls to your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music ...

We are the Dead—Why I Love Armistice Day
World War I profoundly changed the world. Nation-states replaced empires. Russia went communist. Fascism arrived. The West's claim to being the most civilized peoples on Earth was supremely undermined. And out of so much suffering, we received a holiday prioritizing grief and mercy.This bonus episode is me speed-running World War I and sharing some reflections on Armistice Day, Remembrance Day, Veterans Day, or however you might call it.If you carry any of this grief with you personally, I hope you are able to forgive yourself and others. The choices of this world are not always easy, and we make mistakes.This Episode's SponsorsAbsolute Climate: the only standard that’s developed independent of registriesPhilip Lee LLP: legal resources for carbon removal buyers and suppliersListen to the RCC episode with Peter Minor from Absolute ClimateListen to the RCC episode with Ryan Covington from Philip Lee LLPResources"In Flanders Fields" by John McCraeThere are a lot of references in this show.

373: Crucial Questions We Must Answer about Adapting to Climate Change—w/ Dr. Susannah Fisher, author of Sink or Swim
Adaptation begins at home. But it doesn't end there. What do you plan on doing with your family as climate change gets worse? Are you already making plans whether to stay or go? How should states respond as people flee disaster? Who should get access to fish stocks as they migrate to new regions? Once one starts asking these questions, they really don't stop...Today's guest is Susannah Fisher, author of the new book, Sink or Swim: How the World Needs to Adapt to a Changing Climate. It's a wonderful catalogue of questions that asks and frames so many crucial discussions around people, nature, and politics.Much of the first half of the show is about how it feels to start thinking about adaptation and resilience rather than more optimistic mitigation work, and why adaptation can bring its own solace. We might not need to panic just yet... and I enjoyed getting some emotional centering from Susannah's deep experience in A&R research and policy work.This Episode's SponsorsAbsolute Climate: the only standard that’s developed independent of registriesPhilip Lee LLP: legal resources for carbon removal buyers and suppliersListen to the RCC episode with Peter Minor from Absolute ClimateListen to the RCC episode with Ryan Covington from Philip Lee LLPBecome a sponsor by emailing carbon.removal.strategies[at]gmail.comUse this affiliate link to use Descript's transcripting and podcast editing serviceSign up for the 9Zero climate coworking space with my referral codeResourcesBecome a paid subscriber of Reversing Climate ChangeSubscribe to the Reversing Climate Change SubstackSusannah Fisher's Sink or Swim: How the World Needs to Adapt to a Changing ClimateLichen VenturesChristina FigueresOutrage + Optimism podcastAdverse selection, which is the economics term for the problems of insurance and public schooling that I reference"332: If Climate Change Can Impact Behavior, How Much Agency Do We Actually Have?—w/ Clayton Aldern, author of The Weight of Nature"Thames River BarrierThere are various services where you can enter your address and view statistical flood and fire risk.

372: Climate Change on the Battlefield: New Missions, New Kit, New Theaters—w/ Erin Sikorsky, Director of The Center for Climate and Security
Is climate change a fringe and woke distraction in military planning that inhibits lethality? Or is it invaluable strategic context for this century's power projection? What kinds of missions will soldiers be asked to perform in a world that is getting hotter and more complex?Today's guest is Erin Sikorsky, Director of The Center for Climate and Security and author of the new book, Climate Change on the Battlefield: International Military Responses to the Climate Crisis.Though this show is not merely about warfighting and lethality. It's about what it means to have an apolitical military (if that term isn't too contestable). It's also about the military increasingly adapting its own facilities to climate change, and being tasked with many more disaster response missions than it has been previously. What does it mean to have an armed force that is spending more time fighting forest fires than preparing for amphibious assaults? Is this even the correct service to be addressing disasters?I'd like to do many more episodes on this topic in the future. It's one that I find endlessly fascinating.This Episode's SponsorsAbsolute Climate: the only standard that’s developed independent of registriesPhilip Lee LLP: legal resources for carbon removal buyers and suppliersListen to the RCC episode with Peter Minor from Absolute ClimateListen to the RCC episode with Ryan Covington from Philip Lee LLPBecome a sponsor by emailing carbon.removal.strategies[at]gmail.comUse this affiliate link to use Descript's transcripting and podcast editing serviceSign up for the 9Zero climate coworking space with my referral codeResourcesBecome a paid subscriber of Reversing Climate ChangeSubscribe to the Reversing Climate Change SubstackErin Sikorsky's bio at The Center for Climate and SecurityErin's book, Climate Change on the Battlefield: International Military Responses to the Climate CrisisIan W.
