evidence: The point of contention is a peer-reviewed study published last year by Green, a chemistry professor at Michigan Technological University; John Cook, a research fellow at the Global Change Institute at the University of Queensland in Australia; and 10 other scientists who blog under the collective name of Skeptical Science. The scientists examined 4,014 abstracts on climate change and found 97.2 percent of the papers assumed humans play a role in global warming (ClimateWire, May 16, 2013). [...] That statement quickly got boiled down in the popular media to a much simpler message: that 97 percent of scientists believe climate change is caused by humans. President Obama tweeted the 97 percent consensus. Comedian John Oliver did a segment on it that went viral on the Internet. [...] Green and her colleagues found 4,014 papers that endorsed global warming, rejected global warming or explicitly stated they did not hold a position on it. Of these papers, 97.2 percent endorsed the "consensus" that global warming is human caused.
