Scientific American: About that consensus on global warming: 9136 agree, 1 disagrees.
“I just want to highlight this illuminating infographic by James Powell in which, based on more than 2000 peer-reviewed publications, he counts the number of authors from November, 2012 to December, 2013 who explicitly deny global warming (that is, who propose a fundamentally different reason for temperature rise than anthropogenic CO2). The number is exactly one.”
