Which story is carbon dioxide removal actually in?—w/ Rudy Krehbiel of EcoEngineers
17/09/2026 | 1h 20 mins.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.

10/09/2026 | 1h 6 mins.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...

Originally released in September 2020 as season 2, episode 30. Re-released September 2026 with a new introduction.- 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.

People reference the Weimar Republic's transition to Nazi Germany often. But I think they're missing perhaps the most relevant and frightening insight from Adolf Hitler's memoir, Mein Kampf.
It isn't just that economic uncertainty produces political radicalism. It's that bad things can happen when a group which has dominated a multiethnic empire for a long time is expected to start sharing more political and cultural power with the groups they once ruled.
If you haven't listened to the previous episode, "The way of life can be free and beautiful, but we have lost the way—Hitler, Chaplin, & The Great Dictator on climate", go read the article and listen to the episode on Substack. It'll make more sense if you do!

20/08/2026 | 1h 3 mins.CW: this episode discusses genocide and suicide.
I swear I didn't mean to make this episode. All I intended to do was to read the wonderfully moving speech at the end of Charlie Chaplin's The Great Dictator. But somehow that meant that I had to process so much about World War II, the personality of Adolf Hitler, and why monsters can also be boring and/or extremely goofy.
This monologue episode wends its way through the particular moment in history this film was made and why that is significant (as well as what the film got wrong as a result), Hannah Arendt, Mel Brooks, Louis Theroux's manosphere documentary, the banality of evil, why so many huge leaders of countries and companies feel so adolescent, how weird the History Channel was with Hitler content when I was a kid, and so much more.
There is still so much that didn't make it in, but I think I'll share some more soon, in particular about what I find to be the most terrifying part of Mein Kampf. To be continued...

About Reversing Climate Change
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.
