*One* tree.

They hung absolutely critical long-term policy positions on the results of one freaking tree.

At the forefront of those who found suspicious the graphs based on tree rings from the Yamal peninsula in Siberia was [Canadian statistician Steve] McIntyre himself, not least because for years the CRU refused to disclose the data used to construct them. This breached a basic rule of scientific procedure. But last summer the Royal Society insisted on the rule being obeyed, and two months ago Briffa accordingly published on his website some of the data McIntyre had been after.

This was startling enough, as McIntyre demonstrated in an explosive series of posts on his Climate Audit blog, because it showed that the CRU studies were based on cherry-picking hundreds of Siberian samples only to leave those that showed the picture that was wanted. Other studies based on similar data had clearly shown the Medieval Warm Period as hotter than today. Indeed only the evidence from one tree, YADO61, seemed to show a “hockey stick” pattern, and it was this, in light of the extraordinary reverence given to the CRU’s studies, which led McIntyre to dub it “the most influential tree in the world”.

Via Protein Wisdom. At this point, I have to start wondering whether I should be showing these people the same reluctant respect that I would any really successful grifter. Except, of course, that regular devotees of the Spanish Prisoner con are not attempting to rewrite the tax code to keep taking my money.
