A simple resolution to the ‘faint young sun’ paradox?

A faster rotating early-Earth may have compensated for reduced Sun output Guest post submitted by Ian Schumacher The ‘faint young sun’ paradox states that according to star models, billions of years ago the Sun would have only been about 70% as bright as it is today. Given the same environment as today this would result…

Clive Best gives evidence for negative water feedback in Earth’s climate system using the faint sun paradox and CRUTEM4 data

Excerpts from Evidence for Negative Water Feedback by Clive Best Abstract: Positive linear climate feedback for combined water effects is shown to be incompatible with the Faint Sun Paradox. In particular, feedback values of ~2.0 W/m2K-1 favored by current GCM models lead to non physical results at solar radiation levels present one billion years ago.…
