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.
