At last, we have a peer-reviewed paper that accurately surveys how much support there is for anthropogenic global warming among relevant scientists. And the news isn’t good for Al Gore, nor for Barack Obama, who sees climate change as our number one national security threat.
The widely cited figure of 97% of scientists supporting man made global warming theory has always been a fraud:
…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.
