[ASND reminds readers that any claim of “consensus” — whether scientific, legal, political, or otherwise — is not and cannot ever be a claim about truth. Such a claim is provably false because it commits the informal logical fallacy of appeal to a majority . Majorities cannot ever define truth simply because they are majorities. Only verifiable evidence — interpreted under the rubric of the laws of logic — can define truth.]

“The primary paper that is often trotted out in support of the notion of ‘97% consensus’ was written by John Cook… Published in 2013, it is the most widely referenced work on the subject of climate consensus… The paper asserted — falsely, as it turned out — that 97% of the papers the reviewers examined had explicitly endorsed the opinion that humans are causing the majority of the warming of the last 150 years… When one looks at the data, one finds that 7,930 of the papers took no position at all on the subject and were arbitrarily excluded from the count on this ground. If we simply add back all of the papers reviewed, the 97% claimed by Cook and his co-authors falls to 32.6%… A closer look at the paper reveals that the so-called ‘97%‘ included three categories of endorsement of human-caused climate change… The second and third categories would include most skeptics of catastrophic anthropogenic warming… Only by casting a wide net could Cook conclude that there is any type of ‘consensus’… David Legates and his co-authors… reviewed the actual papers used by Cook and found that ‘only 0.3% of the 11,944 abstracts and 1.6% of the smaller sample that excluded those papers expressing no opinion endorsed man-made global warming as they defined it.’ Remarkably, they found that Cook and his assistants had themselves marked only 64 papers — or 0.5% of the 11,944 they said they had reviewed — as explicitly stating that recent warming was mostly man-made… More recently, in 2016, George Mason University (Maibach 2016) surveyed more than 4,000 members of the American Meteorological Society and found that 33% believed that climate change… was mostly natural, or they did not know. Significantly, only 18% believed that a large amount — or all — of additional climate change could be averted.”

This petition has been signed by over 31,000 American scientists

[ASND lists that second citation below the first — despite its significantly higher number of signatories, just among American scientists — because most of the signatories to that petition are not climate scientists (as most of the signatories in the previous citation are).]

“No study — whether a survey of published articles or a survey directly of scientists — has found anything remotely near a 97% consensus not only that the earth has warmed and that human activity has contributed significantly but also that human activity has been the primary driver, that the warming caused by it is dangerous, and that attempting to prevent future warming by reducing CO2 emissions would do more good than harm—and those are the issues debated.”
