Getting to grips with GISS GCM

Posted on June 8, 2012 by Clive Best

I have downloaded the GISS GCM Model II [1] and have begun to investigate it. Since all the predictions of future AGW depend on the results from such models I decided I really needed to understand just how they work. … Continue reading →

Evidence for Negative Water Feedback

Posted on May 23, 2012 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 … Continue reading →

Water – direct evidence of negative feedback

Posted on February 23, 2012 by Clive Best

An  estimate of the climate feedback of water is described below using global temperature measurements[1]. The calculation is based on the assumption that dry arid deserts have essentially zero feedback from water, whereas regions dominated by large oceans  have maximal … Continue reading →
