Behind The Black Postings By Robert Zimmerman

More global warming fraud: A close review of the sources cited in the studies that claimed a 97% scientific consensus supporting global warming has found that claim to be false.

Instead of a 97% consensus, the review found that only 1 to 3% supported global warming. Quite a difference, eh?

The review’s press release nicely summarizes the incompetence or downright dishonesty of three of these consensus studies:

The Oreskes (2004) study claimed 75% consensus and a “remarkable lack of disagreement” by the other 25% of the abstracts she reviewed. Peiser (2005) re-ran her survey and found major discrepancies. Only 1.2% or 13 scientists out of 1,117 agreed with the Intergovernmental Panel on Climate Change (IPCC) view that human activity is the main cause of global warming since 1950. Peiser found that 34 scientists rejected or doubted the alleged ‘consensus’ position outright and 44 claimed natural factors as more influential. At least 470 papers expressed no position on Anthropogenic (human-caused) Global Warming (AGW) whatsoever.

Doran & Zimmerman (2009) only assessed 79 scientists out of 3,146 respondents. Many scientists sent them emails protesting the survey design.

The recent Cook et al (2013) began with the broadest possible ‘consensus’ definition – rendering the idea of ‘consensus’ meaningless. Only 0.54% (or 64 scientists) explicitly agreed. Though Cook’s graphics on The Consensus Project website focus on fossil fuels, his study used the 1996 Houghton declaration which includes other human factors like agriculture and land-use change. Some 7983 scientists or 67% of the ~12,000 papers in the Cook study had no position on climate change. Many scientists publicly denounced Cook for wrongly assessing their work as supporting AGW when it does not.

Based on my experience talking to climate scientists as well as reading innumerable papers, I have always thought that the 97% consensus claim was weak or fishy. Now we not only have proof, we have evidence that the claim was based on lies.

    But 97% sure sounds good, doesn’t it. That’s all that matters. At least they allowed for a few dissenter, or I guess they are called deniers. They could have gone with 99 44/100% pure.
