(Breitbart) 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?
