It’s taken 21 months, four professors, and three associate/ assistant professors, and THIS is the best they could come up with?
The printed version listed no author (the pdf has been updated with John Cooks name*) yet wears the logo of the University of Western Australia (UWA), which will embarrass that university as word spreads of the intellectual weakness of their “Guide”. Did UWA commission this piece of rather inept, qualitative “feel-good” science and clumsy reasoning? Stephan Lewandowsky invited John Cook to speak at UWA and “offer assistance”.
The booklet uses a mislabeled graph with a deceptive scale, won’t show the damning graphs it supposedly debunks, assumes positive feedback occurs despite the weight of empirical evidence against it (Douglass, Spencer, Lindzen), and repeats irrelevant information even though The Skeptics Handbook describes why rising sea levels and glaciers and ice sheets can’t possibly tell us what causes the warming.
It misleadingly discusses a different fingerprint — one that isn’t the key point and isn’t disputed by skeptics. Cause and effect are mixed up, and naturally there are strawmen arguments to unnecessarily destroy for the spectacle of being seen to do something. To top it off, Cook still thinks a measurement is a force of nature that could affect the climate. It’s just confused.
Most of all, the deceptive shell game continues. The Guide offers evidence that supports a direct effect of carbon which amounts to one measly degree if carbon levels double. It offers no evidence that positive feedback will amplify the results up to a wildly high 3 or 4 degrees, and it does not inform readers that there is empirical evidence that the feedback is negative and will thus attenuate that one minor degree. Thus the half-truths are broadcast, but the lies by omission border on deception.
