TIP: “Quantifying the consensus on anthropogenic global warming in the scientific literature”, a 2013 paper by Cook, Nuccitelli, et al, is the most well-known review of the subject. The researchers studied 12,000 peer-reviewed abstracts published between 1991 and 2011, and found that of those taking a position, over 97 percent agreed that climate change is man-made.

A 2009 paper by William R.L. Anderegg et al  (including one researcher from the William and Flora Hewlett Foundation, which also helps fund the API’s Fact-Checking Project), found that between 97 and 98 percent of climate researchers most actively publishing in the field support the tenets of man-made climate change as outlined by the Intergovernmental Panel on Climate Change.

Another study, Examining the Scientific Consensus on Climate Change, by Peter T. Doran and Maggie Kendall Zimmerman of the University of Illinois, found that out of more than 3,000 earth scientists, 82 percent thought human activity is a significant contributing factor in changing mean global temperatures. For climate change specialists, who numbered 79 individuals, 97.4 percent agreed.

In a 2004 study, “The Scientific Consensus on Climate Change,” Naomi Oreskes (then of the University of California-San Diego) analyzed 928 abstracts with the keywords “climate change,” published from 1993 to 2003. She found that zero rejected the consensus position. 

In addition, the scientific consensus is backed by organizations including the American Association for the Advancement of Science, the American Meteorological Society, and national science academies around the world. The UN’s Intergovernmental Panel on Climate Change confirmed its support for this position in 2014 with the publication of its Fifth Assessment Report, summarizing the current scientific knowledge on climate change.
