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.
