Leading climate scientist Cess admits mathematical errors in the AGW theory

Guest essay by Kyoji Kimoto Dr. Robert D. Cess led the following Intercomparison Projects of GCMs for the IPCC Assessment Reports. 1989: Interpretation of Cloud-Climate Feedback as Produced by 14 Atmospheric General Circulation Models. 1990: Intercomparison and Interpretation of Climate Feedback Processes in 19 Atmospheric General Circulation Models. 1991: Interpretation of Snow-Climate Feedback as Produced…

Effective Radiation Level (ERL) Temperature

Guest Post by Willis Eschenbach Lord Monckton has initiated an interesting discussion of the effective radiation level. Such discussions are of value to me because they strike off ideas of things to investigate … so again I go wandering through the data. Let me define a couple terms I’ll use. “Radiation temperature” is the temperature…

Feet of clay: The official errors that exaggerated global warming – part 3

Part III: How the feedback factor f was exaggerated By Christopher Monckton of Brenchley In this series (Part 1 and Part 2) I am exploring the cumulative errors, large and small, through which the climatological establishment has succeeded in greatly exaggerating climate sensitivity. Since the series concerns itself chiefly with equilibrium sensitivity, time-dependencies, including those…

Cloud Feedback

Guest Post by Willis Eschenbach In the comments to Christopher Monckton’s latest post, Nick Stokes drew attention to Soden and Held’s analysis of feedback in the climate models. I reproduce their Table 1 below: Figure 1. Soden and Held’s Table 1, showing all of the feedback parameters calculated from the models. I found several amazing things in…

Feet of clay: The official errors that exaggerated global warming–part 2

Part II: How the central estimate of pre-feedback warming was exaggerated By Christopher Monckton of Brenchley In this series I am exploring the cumulative errors, large and small, through which the climatological establishment has succeeded in greatly exaggerating climate sensitivity. Since the series concerns itself chiefly with equilibrium sensitivity, time-dependencies, including those arising from non-linear…
