Reversing Climate Change is a podcast about carbon removal and climatetech that keeps wandering off into literature, history, philosophy, theology, and geopolitics on the theory that the technical and scientific questions stop making much sense without them. Hosted by Ross Kenyon, who did not go past a year of political philosophy PhD coursework and has visibly not let it go.

    Which story is carbon dioxide removal actually in?—w/ Rudy Krehbiel of EcoEngineers
    Sep 17 2026
    Every industry runs on a mythology, and carbon dioxide removal has several of them available at once. There is the hype cycle, where the trough of disillusionment is a phase you survive on the way to mainstream adoption. There is the solar cost curve, where a technology is expensive and clunky for years and then abruptly cheaper than everything else. There is Moore's Law, and also the one where the world returns to normal after the next election. Each of those carries a promise about the ending that may not deliver.Rudy Krehbiel thinks some of those stories are misleading us, and this episode is about working out which ones. My introduction runs long because I wanted to talk about Charlie Kaufman's Adaptation first, a film about a man who does not know what genre he is in until the genre changes around him, and which you should watch whether or not you have ever thought about a carbon credit.Rudy works on strategic development at EcoEngineers, who also sponsor this show, and he came into carbon dioxide removal from startups and venture capital, which is why he keeps reaching for diffusion curves. His read is that we are at the innovator stage and mistaking it for a trough. His figures, and they hold up against CDR.fyi's April 2026 snapshot: fewer than 50 million tonnes contracted, barely over a million delivered, Microsoft alone accounting for 78.5% of the disclosed total, and a median purchase outside Microsoft still under 100 tonnes. Diagnose that as failure and you start prescribing medicine for a disease nobody has.The harder argument is the one about public goods. Solar panels and EVs deliver something microeconomic you would still buy if climate change did not exist. A tonne of carbon dioxide removed does not. That makes this, in Rudy's words, arguably the hardest public good anyone has tried to fund, and it is why he will not call the ending inevitable. I asked him to name the story we ought to be inside of. What he answered? You'll have to listen to find out.The Show's SponsorEcoEngineers: a full-service advisory and consulting firm focused on carbon dioxide removal, decarbonization, and carbon markets.Listen to the RCC episode I made with David LaGreca from EcoEngineers about how to choose, hire, and fire carbon market contractors.2026 EcoForums Training Series: Navigating Global Carbon and Fuel Regulations, Market Mechanisms, and Life-Cycle Analysis FundamentalsRudy works at EcoEngineers and EcoEngineers sponsors this show.

  • Thinking Little with Mary Berry, Executive Director of The Berry Center—RERELEASE

    Thinking Little with Mary Berry, Executive Director of The Berry Center—RERELEASE
    Sep 10 2026
    Wendell Berry died on August 31st, 2026. A listener once made a Reversing Climate Change bingo card and one of the squares was just "someone mentions Wendell Berry," which turned out to be a rigged square. So rather than write another appreciation, I have pulled the conversation I had with his daughter in 2020 and recorded a new introduction to sit in front of it. The episode I made the week he died is here.Mary Berry runs The Berry Center in New Castle, Kentucky, founded in 2011 after a lifetime of farming. She started it because a forty-year local food movement had produced some very good farmers' markets and almost no change to the culture of farming, and because the best agricultural program her state ever had was being forgotten inside that very state.Listen in to hear more about why the local food movement concentrated on food and skipped land use and the economic lives of farmers, and what you do about any of this if you have no Henry County of your own to go back to.My new introduction is about that last part, and about whether those of who without such roots are like locusts, but somehow worse? What a grim sentence to pen, and there's a lot more coming on this topic soon...This Episode's Sponsor⁠EcoEngineers⁠: a full-service advisory and consulting firm focused on carbon dioxide removal, decarbonization, and carbon markets.⁠Listen to the RCC episode I made with David LaGreca from EcoEngineers about how to choose, hire, and fire carbon market contractors.⁠⁠2026 EcoForums Training Series: Navigating Global Carbon and Fuel Regulations, Market Mechanisms, and Life-Cycle Analysis Fundamentals⁠ResourcesSubscribe to the ⁠⁠Reversing Climate Change Substack⁠⁠⁠⁠Become a paid subscriber⁠⁠ for bonus content and ad-free episodesCheck out my new show, Climate Workers AnonymousThe original 2020 release of this conversationThe Berry Center, and Our Home Place Meat, and the shopThe Berry Center Farm and Forest Institute: the education program Mary describes as the Wendell Berry Farming Program of Sterling College, now run by the Berry Center itselfThe Agrarian Culture Center and the Archive of The Berry Center, which holds her grandfather's and uncle's papers from the Burley Tobacco ProgramThe Land Institute, and Wes Jackson's Becoming Native to This PlaceRemovals, avoidances, and what Wendell Berry thought of making tonnes fungibleWendell Berry, Jayber Crow and the Port William novels, and The World-Ending FireThe 50-Year Farm BillOrganic Valley, founded on what its founder knew about the Burley Tobacco ProgramFour Arguments for the Elimination of Television by Jerry ManderBowling Alone: The Collapse and Revival of American Community by Robert D.

  • Removals, avoidances, and what Wendell Berry thought of making tonnes fungible

    Removals, avoidances, and what Wendell Berry thought of making tonnes fungible
    Sep 3 2026
    Rainbow came into carbon dioxide removal from the outside, kept financing avoidances the whole time, and has watched the market arrive at the position it started from. The company I cofounded, Nori, was merciless about avoidance for its entire existence, so some of that is on me.Wendell Berry died on 31 August, at 92. He has more books referenced on this show than any other author. Early in Nori's life I wrote to him twice inviting him onto this very podcast by explaining that we were making tonnes of soil organic carbon fungible with one another, which may be the worst reading of an audience in my career. He said no both times, kindly. I still have the letters.Listen in to hear more about what it is like to meet someone from Verra and have the first sentence out of your mouth be "I used to think I was better than you", why the hardest parts of carbon market integrity turn out to be structural rather than a failure of anyone's willpower, what the Scouring of the Shire has to do with a methodology list, why I would keep rainforest over carbon removal if someone made me choose, and those ever-present wizards and prophets.This Episode's SponsorEcoEngineers: a full-service advisory and consulting firm focused on carbon dioxide removal, decarbonization, and carbon markets.Listen to the RCC episode I made with David LaGreca from EcoEngineers about how to choose, hire, and fire carbon market contractors.2026 EcoForums Training Series: Navigating Global Carbon and Fuel Regulations, Market Mechanisms, and Life-Cycle Analysis FundamentalsRainbow is a client of mine and I say so in the episode.
