    375: This CDR Marketplace Bought a Biochar Company. Now What?!—w/ Josiah Hunt of Pacific Biochar & Sophie Westover of Wren
    Nov 18 2025

    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.

  • 374: Mining with Microbes: Biomimicry in Copper Extraction—w/ Liz Dennett, PhD, CEO & Founder of Endolith

    374: Mining with Microbes: Biomimicry in Copper Extraction—w/ Liz Dennett, PhD, CEO & Founder of Endolith
    Nov 13 2025
    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 ... Sweep streets like Shakespeare wrote poetry.

  • We are the Dead—Why I Love Armistice Day

    We are the Dead—Why I Love Armistice Day
    Nov 11 2025

    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.
