Recently, President Obama scrapped the “97% consensus of scientists believe in climate change” claim – andraised it 99.5%:
While the president noted that “99.5 percent of scientists and experts [and] 99 percent of world leaders” agree human-caused climate change needs to be reckoned with.
If the President relied on facts rather than hyperbole, he would admit that there is no study claiming that 99.5% of scientists agree with the climate change thesis, and that even the study claiming a 97% consensus of scientists is total bunk.
The study reporting the 97% consensus, “Quantifying the consensus on anthropogenic global warming in the scientific literature,” by John Cook and friends, under the halo of the University of Queensland was published in 2013 and, according to Watts Up With That, when the source data for the study was published online, the University of Queensland got so worried they threatened a lawsuit over use of Cook’s “97% consensus” data for a scientific rebuttal.
