All that data - and that's the conclusion you reach? This just in...an overwhelming majority of the world's scientists agree, global warming is real.
Michael Crichton said: “If it’s consensus, it isn’t science. If it’s science, it isn’t consensus.” Thales of Miletus, Abu Ali Ibn al Haytham, Newton, Einstein, Popper and Feynman thought much the same and said so. Science by head-count is mere politics.
Doran and Zimmerman (2009) and Anderegg
et al. (2010) each concluded that 97% of a few dozen carefully-filtered climate scientists held Man guilty of some of the 0.7 Cº global warming since 1950.
Cook
et al. (2013), in a recent me-too article in
Environment Research Letters, conducted the largest-ever sensational epic blockbuster cast-of-thousands drama survey of scientific papers on climate change. They concluded that 97.1% of abstracts expressing an opinion on climate change endorsed the “scientific consensus”.
Here’s how they did it.
They examined 11,944 abstracts. But they arbitrarily threw out almost 8000 of them on the ground that they had not toed the Party Line by expressing the politically-correct opinion (or any opinion) on climate change.
Next, they ingeniously interchanged three separate versions of the imagined “scientific consensus”: that Man had caused
some warming; that Man had caused
most of the warming since 1950; and that man-made warming would be catastrophic unless the West were shut down and climate sceptics were put on trial – as the appalling James Hansen has suggested – for high crimes against humanity.
It was this last definition – in fact untested in Cook
et al. or, as far as I know, in any other paper – that Mr Obama’s Twitteratus plumped for when he tweeted that 97% of scientists consider climate change not only real but “dangerous”.
The introduction to the Cook paper said that the survey was intended to examine the standard or IPCC “scientific consensus” that most of the warmer weather since 1950 was our fault.
The authors, having consigned 7930 abstracts to the Memory Hole because they had not parroted the Party Line, were left with 4014 abstracts. They marked just 64 of them, or 1.6% of the 4014 abstracts, as endorsing the standard version of “scientific consensus”.
Further examination by Legates
et al. (2013) showed that only 41 of the 64 abstracts, or 1.0% of the 4014 abstracts expressing an opinion on the Party Line, or just 0.3% of the original 11,944 abstracts, had said Yes to the standard version of consensus.
