Thomas Kurz: “Greenhouse Gases and Climate Feedbacks” | Tom Nelson Pod #419

Thomas Kurz discusses chapters from his book Why There Is No Climate Crisis, citing positive reviews, then explains the greenhouse effect and argues CO2’s warming is limited and logarithmic. He claims doubling CO2 yields about 3 W/m² effective forcing, or ~0.9°C via Stefan–Boltzmann calculations, and says even burning all known fossil fuel reserves would add under ~1°C. He argues “climate crisis” claims rely on compounded positive feedbacks in IPCC models, but says observations show models overpredict warming, relative humidity aloft is declining, and a predicted tropical hotspot is missing. He attributes discrepancies to cloud/aerosol cooling, proposing an Earth “thermostat” and net slightly negative feedback. 00:00 Guest and Book Update 02:31 Greenhouse Effect Basics 04:53 CO2 Absorption and Saturation 07:38 Four Ways to Calculate Forcing 17:11 Convert Forcing to Temperature 21:19 Logarithmic Warming Limits 24:20 Fossil Fuels and Max Warming 28:13 Feedbacks Behind the Crisis 32:55 Models vs Observations 41:30 Clouds and Cooling Evidence 55:51 Earth Thermostat Conclusion 57:52 Q&A and Scientific Method 01:01:33 Wrap Up and Farewell “Why There is No Climate Crisis: The Surprising Evidence You Should Know”: https://a.co/d/05rKxsYU https://www.whynoclimatecrisis.com/ Email: info@WhyNoClimateCrisis.com ========= Slides, summaries, references, and transcripts of my podcasts: https://tomn.substack.com/p/podcast-summaries My Linktree: https://linktr.ee/tomanelson1
