Willie Soon and Jonathan Cohler on natural atmospheric CO2 rise #417

Willie Soon and Jonathan Cohler argue the rise in atmospheric CO2 is mostly natural, challenging claims it is 100% manmade from hydrocarbon burning. They cite analyses using bomb-produced carbon-14 showing a single-exponential decay and a short CO2 atmospheric residence time (~3.8 years), contrasting with IPCC claims of thousands of years and criticizing undefined terms like “adjustment time.” They say their work falsifies the Suess effect and that delta-13C of atmospheric change stays near -13‰ from 1978–2022 and in proxies over 500 years, inconsistent with a dominant fossil-fuel signature (~-28‰). They discuss ocean/land cycling, solar/energy imbalance hypotheses, and skepticism of ice-core CO2 constancy claims. 00:00 Big CO2 Claim Questioned 01:30 Decades of Doubt 02:16 Researchers Who Challenged It 04:13 Natural Rise Hypothesis 05:14 Suess Effect Origins 07:35 Bomb Pulse Carbon-14 12:39 Short Residence Time 14:22 Word Games vs Definitions 16:44 3.8 Years Explained 21:21 Bridge Equation Breakthrough 25:34 Peer Pushback and Talks 29:43 Physical Tether Theorem 34:01 Koutsoyiannis Delta13C Test 42:46 Why Delta13C Still Drops 44:23 Lineage and Credit 45:43 Cycle Time vs IPCC 49:14 Debunking Net Sink 51:06 Biosphere Expansion Idea 51:48 Satellite Imbalance Fraud 56:17 Outgassing Explains CO2 Rise 01:01:40 Proxy Limits and Ice Cores 01:09:26 Future CO2 and Benefits 01:13:18 C14 Tracers and Dating 01:15:02 Suez Effect Model Critique 01:21:15 Wrapping Up and Links Jonathan Cohler – “The IPCC Circle of Lies: Five Papers Falsify the Entire Framework” https://x.com/cohler/status/2081407310493081791 Willie Soon – “From Demon to Dinner: The Scientific Case for CO₂ and Fossil Fuels” https://x.com/cohler/status/2081408758308077952 Slides: Jonathan Cohler: https://x.com/cohler/status/2081410426147938599 Willie Soon: https://x.com/cohler/status/2081410908392133048 CERES-Science: https://www.ceres-science.com/ ========= Slides, summaries, references, and transcripts of my podcasts: https://tomn.substack.com/p/podcast-summaries My Linktree: https://linktr.ee/tomanelson1
