In the nearly two years since John Cook and his colleagues published their ’97 percent’ paper claiming a scientific consensus on climate change, the term ’97 percent’ has become something of a mantra for global warming advocates. President Obama tweeted “Ninety-seven percent of scientists agree: #climate change is real, man-made and dangerous.” The Guardian runs a regular column headed “Climate Consensus – the 97%” (regular contributors include co-authors of the original paper).
The paper, published by the Institute of Physic’s IOPScience has been downloaded over 300,000 times and was voted the best 2013 paper in Environmental Research Letters. But does the 97 percent claim stack up? (h/t Bishop Hill)
Richard Tol, Professor of Economics at the University of Sussex and the Professor of the Economics of Climate Change at the Vrije Universiteit, Amsterdam, says no. He has penned a blog, since published in edited form by The Australian, thoroughly debunking Cook’s paper, its methodology, its results, and the way it has been used by climate change advocates.
“Climate research lost its aura of impartiality with the unauthorised release of the email archives of the Climate Research Unit of the University of East Anglia,” Tol says. “Its reputation of competence was shredded by the climate community’s celebration of the flawed works of Michael Mann. Innocence went with the allegations of sexual harassment by Rajendra Pachauri and Peter Gleick’s fake memo.
“Cook’s 97% nonsensus paper shows that the climate community still has a long way to go in weeding out bad research and bad behaviour. If you want to believe that climate researchers are incompetent, biased and secretive, Cook’s paper is an excellent case in point.”
Firstly, Tol points out that science doesn’t depend on consensus. A scientific truth is objective not subjective; that is, it’s true whether one person adheres to it, or everybody adheres to it. Continue reading, here….
