…What the president was referring to was a 2013 paper by the University of Queensland’s John Cook. In his research, Cook studied 11,994 papers published between 1991 and 2011 that mentioned the search words “global warming” and “global climate change.”
Guess what Cook found? Only 32.6% of the papers endorsed the view of anthropogenic (man-made) global warming. But of that group, 97% said that “recent warming is mostly man-made.”
And so, by a nice sleight-of-hand obfuscation, the great “97% consensus” was born.
Don’t believe me? Check out the actual paper, or the abstract, or the original article. In fact, let’s just say thank goodness that the originals are still posted online. Typically, when someone pulls off a con of such massive, world-wide proportions, they subsequently burn the evidence to cover their tracks.
Still don’t believe me? Here’s the actual, posted statement:
We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming.
Bottom line: In the actual study in question, only one-third of the 11,994 academic papers studied could be construed as arguing for man-made warming. Possibly the other two-thirds were more focused on the unprecedented increase in solar activity seen over the past century.
Dr. Richard Lindzen is sick and tired of the media repeating the so-called “97 percent consensus” statistic to show just how strong the global warming agreement is among climate scientists. It’s purely “propaganda,” argues Lindzen….
…Lindzen if referring to the often cited statistic among environmentalists and liberal politicians that 97 percent of climate scientists agree human activities are causing the planet to warm. This sort of argument has been around for decades, but recent use of the statistic can be traced to a 2013 report by Australian researcher John Cook.
Cook’s paper found of the scientific study “abstracts expressing a position on [manmade global warming], 97.1% endorsed the consensus position that humans are causing global warming.” But Cook’s assertion has been heavily criticized by researchers carefully examining his methodology.
A paper by five leading climatologists published in the journal Science and Education found only 41 out of the 11,944 published climate studies examined in Cook’s study explicitly stated mankind has caused most of the warming since 1950 — meaning the actual consensus is 0.3 percent.
“It is astonishing that any journal could have published a paper claiming a 97% climate consensus when on the authors’ own analysis the true consensus was well below 1%,” said Dr. David Legates, a geology professor at the University of Delaware and the study’s lead author….
The myth of the 97% started with ONLY 75-out-of-77 climatologists saying they believe man is the primary cause.
