    362: Will Humanity Pass Through the Great Filter and Become a Permanent Civilization?
    Aug 19 2025
    If there are so many inhabitable planets in the universe, why haven't we made contact with other civilizations? One terrifying answer is that very few civilizations are able to create world-altering technology without also killing themselves off in the process.This monologue episode introduces the concept of Great Filter Events through the work of Dr. David Grinspoon's outstanding book, Earth in Human Hands: Shaping Our Planet's Future.Go read it, and listen to the shows I've done with David Grinspoon in the past!

    361: Carbon-to-Value's Long-Awaited Vindication—w/ Matt Atwood, Founder & CEO of Aircapture
    Aug 11 2025

    A $50M Series A?! In this economy?

    Aircapture recently raised a big round at a time when big raises in climatetech are hard to come by. Their secret? Producing a valuable product better for their customers than what currently exists, and not being dependent upon policy or carbon credits.

    They're doing modular direct air capture in places that otherwise need to buy merchant carbon dioxide from companies that sell gases. Shipping merchant CO2 to the Canary Islands isn't cheap. If modular DAC can provide cheaper and less carbon-intensive CO2, that's surely a win for the climate, the economy, and the learnings that allow us to scale along the way.

    Matt brought his insights about how he built a successful business in carbontech. Folks would be wise to listen up!

    N.B. The photos aren't of actual Aircapture facilities.

    360: Jon Raymond's excellent new climate fiction novel, God and Sex
    Aug 6 2025
    Writing fiction about climate change is notoriously difficult. Some authors have gone for massive ensemble casts to defeat the hyperobject. But what if one zoomed in to smaller, quieter, interpersonal stories?Jon Raymond is a screenwriter and novelist whose work I very much enjoy. He is a frequent collaborator of Kelly Reichardt's, on films such as Old Joy, First Cow, Night Moves, and Showing Up. He also adapted James M. Cain's novel, Mildred Pierce, which became an HBO miniseries starring Kate Winslett.His novels in particular deal with our place in a world with a changing climate. His previous work, Denial, concerns itself with questions of climate culpability for the individual person with great skill. His new novel, God and Sex, asks poignant questions about the nature of miracles and doubt from within a climate context. We discuss both books at length in this show.They're both worth reading. Pick a copy of God and Sex while it is fresh off the presses!This Episode's SponsorsPhilip Lee LLP: legal resources for carbon removal buyers and suppliers⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Arbonics⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: forestry project developer in the EU⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Listen to the RCC episode with Lisett Luik from Arbonics⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Become a sponsor by emailing carbon.removal.strategies[at]gmail.com⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Use this affiliate link to use Descript's transcripting and podcast editing service⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Use this affiliate link to use Riverside to record your podcasts⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Sign up for the 9Zero climate coworking space with my referral code⁠⁠⁠⁠⁠⁠⁠Resources⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Become a paid subscriber of Reversing Climate Change⁠⁠⁠⁠Buy God and SexDenial⁠Bonnie "Prince" BillyKim Stanley RobinsonAdolf Eichmann's trialEichmann in Jerusalem by Hannah ArendtManicheaismJean ValjeanGo (re)watch The Sixth Sense—it's great.Ursula K Le Guin

    359: Why Is the Pulp and Paper Industry So Great for CDR?—w/ Natalie Khtikian & Jon Rhone, Cofounders of CO280
    Jul 29 2025

    Many hardtech entrepreneurs develop a technology and then figure out how to commercialize it. What happens if you find an industry with potential and then engineer a solution to open an entirely new market to them?

    Today's show is with two of the cofounders of CO280: Natalie Khtikian, the Chief Commercial Officer, and Jonathan Rhone, the Chief Executive Officer.

    Natalie and John explain what it's like working with an industry as established as pulp and paper, structuring joint venture deals with them, and showing them the potential upside to opening business lines in carbon removal.

    The deal mechanics of joint ventures for carbon removal are discussed (though probably deserve their own full show!), and Natalie shares some reasons why she is optimistic about carbon removal despite some of the headwinds the industry is currently experiencing.

    357: Making Graphite from Carbon Removal for Lithium-Ion Batteries—w/ Makoto Eyre, Founder & CEO of Homeostasis
    Jul 15 2025

    We primarily talk about pulling carbon dioxide out of the atmosphere and ocean and storing it. But there are some places where we should actually be using it productively. Is graphite for lithium-ion batteries one of those places?

    Makoto Eyre is the Founder and CEO of Homeostasis, a Tacoma-based company making graphite from carbon dioxide. In the future they aim to colocate their reactors with carbon capture and/or removal to create a modular and distributed system of graphite production.

    Before the Industrial Revolution we had artisanal production and cottage industries. Then we had centralization and automation. What will production look like when centralization is no longer necessary to provide the economies of scale we had always thought it needed?

    The conventional ways graphite is produced is also not so ecologically-inclined. What if the future were both simpler on supply chains and ecology?

    356: The World's First International Transfer of Carbon Removals Between Countries Under the Paris Agreement—w/ Victoria Harvey, CDR Strategy Lead at ClimeFi
    Jul 9 2025

    When you think of Article 6 of the Paris Agreement, you probably aren't thinking about carbon removal. But should you be?

    Today's guest is Victoria Harvey, CDR Strategy Lead at ClimeFi. ClimeFi just structured the world's first Article 6.2 international transfer of durable carbon removal credits between Norway and Switzerland, and there's a lot to discuss!

    What is the relationship between corporate climate action and national obligations? Do NDCs (Nationally Determined Contributions) impact corporate net-zero targets? Can corporate action satisfy national goals? Does that somehow leave us double-counting carbon removal?

    This and so many more questions about the mechanics of CDR and climate action get discussed! Tune in to learn more and hear about ClimeFi's important work.

    355: Is a Carbon Credit Registry Creating Methodologies an Inherent Conflict of Interest?—w/ Peter Minor, Co-Founder & CEO of Absolute Climate
    Jul 3 2025
    Many a business was launched in carbon credits trying to fix a conflict of interest problem. Has Absolute Climate cracked the code? Should registries get out of the methodology development business?Peter Minor, CEO and Co-Founder of Absolute Climate, is on the show today to talk about the many issues of trying to create an ultimate standard in carbon removal (hence the amazing xkcd meme), and how he thinks the current system is set up to fail.Are we doomed to always face conflicts of interest? Do we inevitably end up thinking not in terms of ultimate design victory, but balance of power? Is it all just "a dogfight in the Wild West?" Can we all agree upon the same standard?Listen in to Peter and Ross think the big thoughts and try to white hat hack the system to advance CDR.This Episode's Sponsors⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Arbonics⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠CDRjobs⁠⁠Listen to the RCC episode I did about CDRjobs' Salary Survey and why carbon removers should fill it out⁠Fill out the ⁠⁠⁠2025 CDRjobs Salary Survey⁠⁠ HERE⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Listen to the RCC episode with Lisett Luik from Arbonics⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Become a sponsor by emailing carbon.removal.strategies[at]gmail.com⁠⁠⁠⁠⁠⁠⁠Use this affiliate link to use Descript's transcripting and podcast editing service⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Use this affiliate link to use Riverside to record your podcasts⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Sign up for the 9Zero climate coworking space with my referral code⁠⁠⁠⁠Resources⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Become a paid subscriber of Reversing Climate Change⁠⁠⁠⁠Absolute Climate"Never complain, never explain"Streisand effectThe Civil Law Tradition by John Henry Merryman and Rogelio Pérez-Perdomo"Common law" article on WikipediaThe Wide Lens by Ron Adner⁠The Spotify image is the absolutely legendary and final word on the quest for One True StandardTM, courtesy of xkcd under Creative Commons.
