The 97% Myth means 97% Failure of Alarmists

Global Warming Nazis (GWNs) stop showing your ignorance. This blog has previously exposed this 97% figure to be wrong many times (eg inter alia here, here and here) and it has also been exposed elsewhere as coming from flawed studies in many other locations.

And yet the GWNs keep rolling out this false figure.  One must ask why?

Is it because that is all they have? They know that the AGW hypothesis has been falsified. They know that they have no proof that increasing atmospheric CO2 from fossil fuel burning drives global climate warming.

Then there is that other false claim from the GWNs. Sceptics are funded by BigOil. Also false. (Pssst B/O...if you have a few mill to spare the bank account details are at the top of the page....)

This however has not stopped them from getting more and more shrill.

So, our side, the realists side of the "climate change" debate have to keep shooting down their falsehoods. One will be re-blasted here and then the MWP myth in our next post.

Joe Bast and Roy Spencer have written the latest exposee of the Myth of the Climate Change '97%'.
Last week Secretary of State John Kerry warned graduating students at Boston College of the "crippling consequences" of climate change. "Ninety-seven percent of the world's scientists," he added, "tell us this is urgent." 
Where did Mr. Kerry get the 97% figure? Perhaps from his boss, President Obama, who tweeted on May 16 that "Ninety-seven percent of scientists agree: #climate change is real, man-made and dangerous." Or maybe from NASA, which posted (in more measured language) on its website, "Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities." 
Yet the assertion that 97% of scientists believe that climate change is a man-made, urgent problem is a fiction.
The first talk of the Naomi Oreskes "study" that is so ridiculous that surely neither side takes any notice of it. Then they move on to the Doran and Zimmerman 2009 study.
It reported the results of a two-question online survey of selected scientists. Mr. Doran and Ms. Zimmerman claimed "97 percent of climate scientists agree" that global temperatures have risen and that humans are a significant contributing factor.
The survey's questions don't reveal much of interest. Most scientists who are skeptical of catastrophic global warming nevertheless would answer "yes" to both questions. The survey was silent on whether the human impact is large enough to constitute a problem.
 Moving on to Anderegg:
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." There was no mention of how dangerous this climate change might be; and, of course, 200 researchers out of the thousands who have contributed to the climate science debate is not evidence of consensus.
Then they come to the most ridiculous study by Cook et al which was exposed by Lord Monckton on these pages HERE - where it was shown that Cook's 97.1% was in fact a miniscule 0.3%.

Finally, the U.N.'s Intergovernmental Panel on Climate Change—which claims to speak for more than 2,500 scientists—is probably the most frequently cited source for the consensus. Its latest report claims that "human interference with the climate system is occurring, and climate change poses risks for human and natural systems." Yet relatively few have either written on or reviewed research having to do with the key question: How much of the temperature increase and other climate changes observed in the 20th century was caused by man-made greenhouse-gas emissions? The IPCC lists only 41 authors and editors of the relevant chapter of the Fifth Assessment Report addressing "anthropogenic and natural radiative forcing." 
Of the various petitions on global warming circulated for signatures by scientists, the one by the Petition Project, a group of physicists and physical chemists based in La Jolla, Calif., has by far the most signatures—more than 31,000 (more than 9,000 with a Ph.D.). It was most recently published in 2009, and most signers were added or reaffirmed since 2007. The petition states that "there is no convincing scientific evidence that human release of . . . carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate." 
We could go on, but the larger point is plain. There is no basis for the claim that 97% of scientists believe that man-made climate change is a dangerous problem.
