Cohler/Soon: “ Response to Ed Berry’s recent presentation” #431

from Tom Nelson Hosted by Thomas Nelson

Jonathan Cohler, joined by Willie Soon, says he is correcting false statements Ed Berry made about their paper “Dominance of Natural Atmospheric CO2 Dynamics,” which is under review and posted online. Cohler argues Berry wrongly claimed they ignored Berry’s work, presented an identical delta-14C “proof,” and called for a carbon-cycle model; Cohler says they cited Berry prominently and used newer radiocarbon data (Hua et al. 2022) and Koutsoyiannis 2024. They distinguish residence time (~3.8 years) from radiocarbon relaxation time (~18.4 years), claim a bridge equation links them, and assert their new work mathematically refutes Bern multi-exponential/adjustment-time models. They also discuss conflicts with the CO2 Coalition over attributing CO2 rise to humans. 00:00 Why This Rebuttal 01:23 Berry Claims Overview 03:16 New Radiocarbon Data 05:19 Lie One Citation Record 07:33 Lie Two Not Identical 10:00 Lie Three No Model Needed 12:34 Why Skip Berry 2023 13:16 Residence vs Relaxation 15:57 Bridge Equation Results 17:20 Math Theorems Against Bern 18:29 Independent Checks and Implications 21:38 Host Q and IPCC Confusion 22:49 Soon on Adjustment Time Myth 24:55 Table Consensus and Bern Failure 26:25 Bomb 14C Reality Check 27:30 Why Bomb Tests Matter 28:19 Ethics And Accusations 29:27 Data Driven Challenge 31:08 CO2 Coalition Split 33:32 Math Not Debate 36:55 Ugly Email Wars 40:01 Science Over Ego 42:52 Searchers Versus Blockers 43:22 Passing The Torch 45:08 Final Thanks And Goodbye https://x.com/cohler https://papers.jcohler.com/ ========= Slides, summaries, references, and transcripts of my podcasts: https://tomn.substack.com/p/podcast-summaries My Linktree: https://linktr.ee/tomanelson1
