OPEN to interpretation “90% likely”
No doubt it will be said that some of these papers don’t mention AGW because it’s taken for granted.
Wow, that takes me back!
First, some background. Naomi Oreskes looked at a sample of 928 papers in refereed scientific journals and found that not one disagreed with the scientific consensus. This report was peer-reviewed and published in the journal Science.
Al Gore used this result in his film.
Benny Peiser disputed this and claimed 34 rejected or doubted the consensus. When
Tim Lambert asked Peiser for his list and checked them only one paper on his list of 34
actually rejected the consensus (from the American Association of Petroleum Geologists!) and it
wasn’t a peer-reviewed paper. Oreskes was right.
Fast-forward nearly a year and we get
Schulte’s effort. Tim Lambert decided to
audit his claims.
The result? Only three actually
reject the consensus: One published in the American Association of Petroleum Geologists Bulletin; one “arguing for cosmic rays, which doesn’t explain how they could make a difference over the past 50 years when the cosmic rayflux hasn’t changed over that period”; and one “which is just a rubbish paper that should not have been published. (What is the next number in this sequence? 60. Their answer is 60.)”
But even without the audit, let’s take the quote from your article:
Of 528 total papers on climate change, only 38 (7%) gave an explicit endorsement of the consensus. If one considers “implicit” endorsement (accepting the consensus without explicit statement), the figure rises to 45%. However, while only 32 papers (6%) reject the consensus outright, the largest category (48%) are neutral papers, refusing to either accept or reject the hypothesis. This is no “consensus.”
And now let’s report exactly the same results with different words:
Of 528 total papers on climate change, only 7 (1%) gave an explicit rejection of the consensus. If one considers “implicit” rejection (rejecting the consensus without explicit statement), the figure rises to 6%. However, while 244 papers (45%) accept the consensus outright, the largest category (48%) are neutral papers, that do not address the cause of global warming.
So:
45% accept the consensus.
6% reject the consensus.
48% of the papers were neutral, neither accepting or rejecting the hypothesis. Why? 24% (half of the neutral papers) were simply reporting new data/observations on climate change. 2% were conducting new research on the consensus question. No idea about the rest. However, the point is they did not address the issue – just like many
other papers on completely unrelated topics. Should we include those too? That will make the percentages
really small.
Of course, the only thing we can meaningfully
do with papers that do not address the issue is
ignore them.
If we do that we find over 88% of the papers published between 2004 and 2007 that addressed the issue of AGW accepted the consensus, and only 12% rejected it. Auditing shows that of those 12%, only
three actually reject it, and they aren’t exactly Earth-changing.
The clincher? After all that, Schulte’s paper was ultimately rejected.
By Energy and Environment! So you’re using a paper that
failed peer review. Does that count as “grey”?
