percentage of scientists who believe climate change is real
On his Twitter account, President Obama tweets: âNinety-seven percent of scientists agree: #climate change is real, man-made and dangerous.â Not only does Obama sloppily equate âscientistsâ with âclimate scientists,â but more importantly he added âdangerousâ to the 97% claim, which is not there in the literature.
Surely the most suspicious â97 percentâ study was conducted in 2013 by Australian scientist John Cook â author of the 2011 book Climate Change Denial: Heads in the Sand and creator of the blog Skeptical Science (subtitle: âGetting skeptical about global warming skepticism.â).
