Quote:http://climatecrocks.com/2012/12/14/deniers-reach-for-cherry-come-up-with-pits/Professor Steve Sherwood, of the University of New South Wales Climate Change Research Centre, is a lead author on Chapter 7. Commenting on the publicly-quoted paragraph about cosmic rays (the one cited by Delingpole as a “game changer) Professor Sherwood told me
The single sentence that this guy pulls out is simply paraphrasing an argument that has been put forward by a few controversial papers (note the crucial word “seems”) purporting significant cosmic-ray influences on climate. Its existence in the draft is proof that we considered all peer-reviewed literature, including potentially important papers that deviate from the herd. The rest of the paragraph from which he has lifted this sentence, however, goes on to show that subsequent peer-reviewed literature has discredited the assumptions and/or methodology of those papers, and failed to find any effect. The absence of evidence for significant cosmic-ray effects is clearly stated in the executive summary. This guy’s spin is truly bizarre. Anyone who would buy the idea that this is a “game changer” is obviously not really looking at what is there.
The IPCC has made no such admission has it???
Sherwood uses theory—his dissatisfaction with one theory of how solar amplification might work—to ignore the (admitted) evidence for some mechanism of solar amplification. Putting theory over evidence is not science. It is the exact definitional opposite of science (see Feynman snippet above).
