LeafByNiggle and I have been discussing the 97% consensus myth, in particular the Cook et al 2013 study. I have accused Cook of cooking the results. In short, Cook et al only found that 2% of the articles analyzed fell in the highest level of endorsement. In other words, only 2% explicitly endorsed the proposition that human activities are causing most of the global warming (explicit endorsement with quantification). However, this result was not published in the article. Instead, they lumped the 2% in with the 95% of the papers which either implicitly or explicitly endorsed the proposition that human activities are causing some global warming. The resulting 97% has then been represented by the authors, implicitly in the 2013 paper and explicitly in other publications and statements, as exemplifying the highest level of endorsement. They turned 2% into 97%.

I don’t think the phrase “most of the warming” was ever identified with the 97% figure.
Again, the 97.1% comes from Table 3. It is the percent of the 4000 articles which “Endorse AGW.” How do they define AGW? The “scientific consensus that human activity is very likely causing
most of the current GW.” So they want us to believe that 97% of the articles not only endorse the idea that human activities are contributing to global warming, they also want to convey that human activities are
causing most of it. In other words, they want us to believe that 97% were Category 1…And Cook himself continues the deception in another paper, Bedford and Cook (2013) which says: “Cook et al. (2013) found that over 97% endorsed the view that the Earth is warming up and human emissions of greenhouse gases are the
main cause.” Cook explicitly misrepresents his own results.
But once again, I ask you, if the surveys I have mentioned are fatally flawed surveys, which survey is a better, more accurate survey? It seems that doing a good survey would be the best way to discredit the Cook survey.
There have been other surveys which reveal more tepid support among scientists for the claim that human CO2 emissions are driving the climate. See, e.g. Bray and Von Storch and another survey by Klaus-Martin Schultz. However, I don’t cite them as being definitive, just as evidence that the consensus is not as overwhelming as portrayed by establishment researchers.
