S3E57: Is direct air capture an energetic dead end?—w/ Paul Hawken, author of Regeneration: Ending the Climate Crisis in One Generation
In this week’s episode, the name of the goal is not ‘net zero’, it’s regeneration. We’re joined by Paul Hawken: author of many books including Drawdown and Regeneration, activist, and entrepreneur to talk about the tools that he believes can end the climate crisis. Paul takes us through the concept of "carbon tunnel syndrome," an overemphasis on carbon as a mere numerical figure, often favored by the tech industry. He also sheds light on the staggering statistic that less than 1% of the global population actively works on climate solutions. He also is quite skeptical that direct air capture will ever make energetic sense.Throughout history, the climate movement has urged individuals to focus on future existential threats. However, Paul highlights a stark reality: over five billion people wake up every day preoccupied with current existential threats.This episode serves as a stark reflection on the array of solutions within our grasp. It underscores the urgency of prioritizing Earth's regeneration and explores the intricate relationship between carbon removal and the broader climate solution landscape. Join us in this candid conversation about addressing the climate crisis head-on, and be sure to check out Paul’s new book Regeneration: Ending the Climate Crisis in One Generation.Connect with NoriPurchase Nori Carbon RemovalsNori's websiteNori on TwitterCheck out our other podcast, Carbon Removal NewsroomCarbon Removal Memes on TwitterCarbon Removal Memes on InstagramResourcesPaul Hawken’s websitePaul Hawken on XProject DrawdownDrawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global WarmingRegeneration: Ending the Climate Crisis in One Generation

S3E56: Could there be a just solar geoengineering?—w/ Shuchi Talati, Founder of The Alliance for Just Deliberation on Solar Geoengineering
Solar geoengineering. It's not just a question of whether or not to do it, but of how it might be done and why.This week we are joined by Shuchi Talati, founder of The Alliance for Just Deliberation on Solar Geoengineering, to talk about who is making decisions about solar geoengineering and whether or not populations most vulnerable to climate change have a seat at the table.Solar geoengineering or “Solar Radiation Modification/Management (SRM)” is the large-scale and intentional intervention to increase the amount of sunlight reflected back into space. The purpose is to temporarily limit temperature increase.Shuchi walks us through why the Alliance is not for or against SRM, why refusing to discuss or research RSM is potentially an inherently privileged standpoint, and why she believes we should center voices from regions already experiencing horrific climate impacts.Listen in to find out who is currently researching SRM, what the potential risks and benefits are, and how the Alliance plans to make such a controversial topic more open and accessible.Connect with NoriPurchase Nori Carbon RemovalsNori's websiteNori on TwitterCheck out our other podcast, Carbon Removal NewsroomCarbon Removal Memes on TwitterCarbon Removal Memes on InstagramResourcesThe Alliance for Just Deliberation on Solar GeoengineeringThe Ministry for the Future by Kim Stanley RobinsonUNEP 2023 ReportFollow Shuchi on XThe Degrees Initiative
