351: The Virgin Earth Challenge & the Early Days of Carbon Removal: Lessons of Curiosity, Discipline, & Grace—w/ Dave Addison, Founder of Planetary Practitioners
Carbon removal isn't that old. So for someone who's been involved in it for almost fifteen years... that's an elder. And today he's bringing the wisdom he earned the hard way.Dave Addison is formerly the Virgin Earth Challenge Manager, an effort he began working on in 2010. That's about six years before I had even heard of CDR, so a long time indeed!Last year, Dave started Planetary Practitioners, a consultancy founded on a long-run vision of helping much more of humankind access decent work in net-positive industries. You can read his writing and keep up with his work here.One pattern you might notice in shows is that many of the lessons aren't merely about commercial strategy or TRL or unit economics. Much of the best advice is how to walk upon the Earth in a way that shows you belong here. So today, it's more emotional than average. For those of you who want or need such an experience, it is here for you, and I hope you enjoy this conversation with my good friend, Dave.This Episode's SponsorsClimeFiArbonicsListen 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 Change"Keep Going", from Dave's Substack for Planetary PractitionersVirgin Earth ChallengeLongitude rewards systemCarl Sagan's Cosmos: A Personal VoyageDavid Grinspoon's Earth in Human Hands: Shaping Our Planet's FutureThe Telepathy TapesCharles C.

349: How Will Carbon Dioxide Removal Fit into Compliance Markets?—w/ Mike Azlen, Carbon Cap Management LLP

Might that be the demand boost that carbon removal needs to scale?There is also bonus content from this episode about some of Mike's observations about VCM failures.

345: Why Too Many TV Antiheroes May Be Bad for the Climate
Fair warning: this episode spoils a lot of (older) media.Antiheroes make for great television. But why are we obsessed with them? Why are they in nearly all prestige dramas? Is this a result of our cultural beliefs, or is it (re)producing a culture of cynical realism? What impacts might it have for politics and climate change?This ascendancy of the antihero is a trend I've been watching (and often enjoying) since my teen years. Shows like The Sopranos helped bring television to its lofty artistic status, but it did so by confusing the natural empathy that good storytelling generates. The longer one watches shows like The Sopranos, the more one ends up rooting for bad guys to be successful. In a world that is ever more mediated by media, could a similar trend be happening in politics?Today's show is an attempt to make sense of the antihero through a number of prestige dramas, and look for some ways of telling stories that don't lead us into the abyss of constant moral ambiguity.Today we're going to talk about hope, reclaiming moral authority, and why it's cool to believe in things. I hope you'll join me in that ambition.This Episode's SponsorsOffstreamArbonicsListen to the RCC episode with Lisett Luik from ArbonicsEmail me to sponsor at carbon.removal.strategies [at] gmail.com.ResourcesBecome a paid subscriber of Reversing Climate Change"The judge speaks in the name of justice; the priest speaks in the name of pity, which is nothing but a more lofty justice."- Victor Hugo, Les Misérables"Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?

344: The Optimal Number of Travel Deaths Is Non-Zero: Carbon Removal Trade-Offs in Scale & Quality
It's a jarring phrase. There's an even more jarring version of it in this episode. You've been warned.Economists are well-known for gnomic sentences that can sound cruel. For some, that's one of the job's many perks. But that doesn't mean that there isn't some truth in representing decisions as trade-offs.Today is a bonus monologue episode where I am going to unpack this phrase (and its nastier cousin) and explain what it has to teach the carbon removal industry as it grapples with the tension between scale and quality.This Episode's SponsorsOffstreamArbonicsListen to the RCC episode with Lisett Luik from ArbonicsResourcesBecome a paid subscriber of Reversing Climate Change"There ain't no such thing as a free lunch" Wikipedia pageFollow the Reversing Climate Change podcast on LinkedIn
