Debunking the 97% ‘consensus’ on global warming

The main pillar of the warmist argument is the contention that a “consensus” exists among scientists that global warming is caused by man and threatens catastrophe. But a Canada-based group calling itself Friends of Science has just completed a review of the four main studies used to document the alleged consensus and found that only 1 – 3% of respondents “explicitly stated agreement with the IPCC declarations on global warming,” and that there was “no agreement with a catastrophic view.”

“These ‘consensus’ surveys appear to be used as a ‘social proof,’” says Ken Gregory, research director of Friends of Science. “Just because a science paper includes the words ‘global climate change’ this does not define the cause, impact or possible mitigation. The 97% claim is contrived in all cases.”

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.
