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…

Willis and I walk the Planck

By Christopher Monckton of Brenchley I do apologize for not having replied sooner to my friend the irrepressible, irascible, highly improbable but always fascinating Willis Eschenbach, who on August 15 had commented on a brace of earlier postings by me on the vexed question of climate sensitivity. The delay is because my lovely wife and…

Putting It On The Line

Guest Post by Willis Eschenbach Thanks to an alert commenter, half of my last post was shown to be in error. Like most folks, I really, really hate to be publicly wrong, and of course I do my utmost to avoid it. But sometimes I overlook something, or my logical staircase is missing some steps,…

Pre- and Post-Feedback Sensitivity

Guest Post by Willis Eschenbach [UPDATE TWO: Rather than trying to cooper up the errors, I have simply removed the incorrect sections and left the calculation of the Planck feedback intact. I think that it is right … however, as events remind me too frequently … I could be wrong … ] [UPDATE: As Jan Kjetil Andersen…

Introducing the global-warming exaggeration factor X

Guest essay by Christopher Monckton of Brenchley Recently I provided – based on a characteristically interesting email from Roger Taguchi – a demonstration that IPCC has at least doubled true climate sensitivity. In this follow-up piece, will you please welcome the global-warming exaggeration factor X. First, a breathless recap on my summary of Roger’s argument.…
