The club used by global warming alarmists to silence critics, “That 97% of scientist agree.” Well, while accurate as presented, it failed to tell the whole truth. This consensus view is from a 2009 article in “Eos, Transactions American Geophysical Union” by Maggie Kendall Zimmerman, a student at the University of Illinois, and her master’s thesis adviser Peter Doran.
The 97% figure in the Zimmerman/Doran survey represents the views of only 79 respondents out of the 3,146 who responded to the survey. In order to “cook” the numbers did they they continued to add qualifiers to the returned surveys until they had the proper result. It is funny they receive over 3000 answered questionnaires and only use 79. One has to wonder how the other 3,067 answered.
Then in 2010, William R. Love Anderegg, a student at Stanford University, used Google Scholar to identify the views of the most prolific writers on climate change. His findings were published in Proceedings of the National Academies of Sciences. Mr. Love Anderegg found that 97% to 98% of the 200 most prolific writers on climate change believe “anthropogenic greenhouse gases have been responsible for ‘most’ of the ‘unequivocal’ warming.”
Then in 2013, John Cook, and some of his friends reviewed abstracts of peer-reviewed papers published from 1991 to 2011. Mr. Cook reported that 97% of those who stated a position explicitly or implicitly suggest that human activity is responsible for some warming. His findings were published in Environmental Research Letters.
Mr. Cook’s 2010, work was quickly debunked. In Science and Education in August 2013, for example, David R. Legates (a professor of geography at the University of Delaware and former director of its Center for Climatic Research) and three coauthors reviewed the same papers as did Mr. Cook and found “only 41 papers—0.3 percent of all 11,944 abstracts or 1.0 percent of the 4,014 expressing an opinion, and not 97.1 percent—had been found to endorse” the claim that human activity is causing most of the current warming.
So instead of 97% agreeing the actual number is .3%. Quite a difference there.
It’s simply untrue that the scientific community has decided almost as a whole that global warming is happening, man-made and problematic. Many scientists believe that’s the case. Many others don’t. At this point, it’s merely a controversial unproven theory.
In 2012 a survey asked the American Meteorological Society members, “Is man-made global warming is dangerous?” Only 39.5% of 1,854 who responded to a survey said, “Yes.”
