97 Articles Refuting The "97% Consensus"


The 97% "consensus" study, Cook et al. (2013) has been thoroughly refuted in scholarly peer-reviewed journals, by major news media, public policy organizations and think tanks, highly credentialed scientists and extensively in the climate blogosphere. The shoddy methodology of Cook's study has been shown to be so fatally flawed that well known climate scientists have publicly spoken out against it,
"The '97% consensus' article is poorly conceived, poorly designed and poorly executed. It obscures the complexities of the climate issue and it is a sign of the desperately poor level of public and policy debate in this country [UK] that the energy minister should cite it."

- Mike Hulme, Ph.D. Professor of Climate Change, University of East Anglia (UEA)
The following is a list of 97 articles that refute Cook's (poorly conceived, poorly designed and poorly executed) 97% "consensus" study. The fact that anyone continues to bring up such soundly debunked nonsense like Cook's study is an embarrassment to science.



Summary: Cook et al. (2013) attempted to categorize 11,944 abstracts [brief summaries] of papers (not entire papers) to their level of endorsement of AGW and found 7930 (66%) held no position on AGW. While only 65 papers (0.5%) explicitly endorsed and quantified AGW as +50% (Humans are the primary cause). A later analysis by Legates et al. (2013) found there to be only 41 papers (0.3%) that supported this definition. Cook et al.'s methodology was so fatally flawed that they falsely classified skeptic papers as endorsing AGW, apparently believing to know more about the papers than their authors. The second part of Cook et al. (2013), the author self-ratings simply confirmed the worthlessness of their methodology, as they were not representative of the sample since only 4% of the authors (1189 of 29,083) rated their own papers and of these 63% disagreed with the abstract ratings.

Methodology: The data (11,944 abstracts) used in Cook et al. (2013) came from searching the Web of Science database for results containing the key phrases 'global warming' or 'global climate change' - regardless of what type of publication they appeared in. Only a small minority of these were actually published in climate science journals, instead the publications included ones like the International Journal Of Vehicle Design, Livestock Science and Waste Management. The results were not even analyzed by scientists but rather incompetent amateurs with credentials such as "zoo volunteer" and "scuba diving". They were chosen by the lead author John Cook (a cartoonist) because they all comment on his deceptively named, alarmist blog 'Skeptical Science' and could be counted on to push his manufactured talking point.

* All the other "97% consensus" studies: e.g. Doran & Zimmerman (2009), Anderegg et al. (2010) and Oreskes (2004) have been refuted by peer-review.

Rebuttals to Criticisms:

Criticism: "Tol (2014) was rejected by other journals for being flawed."

Rebuttal: Dr. Tol's 2014 paper was actually censored by Environmental Research Letters (ERL) due to having multiple outspoken alarmist scientists on its editorial board (e.g. Peter Gleick and Stefan Rahmstorf) and politely declined by two other journals for being "out of scope" (off topic) not flawed.



Criticism: "Tol (2014) has 24 errors."

Rebuttal: Dr. Tol refuted all of these claims in a post online and in his published rejoinder.



Criticism: "Dr. Tol confirmed the 97% consensus."

Rebuttal: This misleading claim originated with one of the co-authors of Cook et al. (2013) - Dana Nuccitelli. Dr. Tol refuted this claim in a scathing editorial he wrote for The Guardian:
"Dana Nuccitelli writes that I “accidentally confirm the results of last year’s 97% global warming consensus study”. Nothing could be further from the truth. I show that the 97% consensus claim does not stand up. [...]

In his defence, Nuccitelli argues that I do not dispute their main result. Nuccitelli fundamentally misunderstands research. Science is not a set of results. Science is a method. If the method is wrong, the results are worthless." - Dr. Richard Tol


Criticism: "Dr. Tol claims the consensus is actually 91%."

Rebuttal: This misleading claim originated with one of the co-authors of Cook et al. (2013) - Dana Nuccitelli and falsely spread by websites like Politifact. Dr. Tol refuted this claim in an email to Politifact.
"I never claimed that the consensus rate is 91%. [...]

Do check the grammar: "would […] in that case" does in no way indicate my agreement with the number. In fact, I make it very clear that any number based on Cook’s data is unreliable." - Dr. Richard Tol

There are more than a few piece rebutting the "97% Consensus" on the Australian Climate Sceptics blog, including:-

Okay, okay, okay! So the 97 Percent is reduced to the Consensus of the Few!

Well...Okay! but...

Science doesn't run on consensus. Hey, the Few could be right!!

This was a bad joke when Naomi Oreskes started it at Scripps Institoot for the fleecing of rich San Diego widows. She was in the great traditions of Roger Revelle and Charles David Keeling in faking data to make it appear man had power over the atmosphere. (Pardon me while I vomit.) The story went on with the Doran-Zimmerman fraud at the U of I, Chicago campus.

I document the whole thing in my book "Vapor Tiger" on sale at Amazon.com in paperback or Kindle and have gotten nine five star reviews!
