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”.
But more dramatic still has been the new evidence from the CRU’s leaked documents, showing just how the evidence was finally rigged. The most quoted remark in those emails has been one from Prof Jones in 1999, reporting that he had used “Mike [Mann]’s Nature trick of adding in the real temps” to “Keith’s” graph, in order to “hide the decline”. Invariably this has been quoted out of context. Its true significance, we can now see, is that what they intended to hide was the awkward fact that, apart from that one tree, the Yamal data showed temperatures not having risen in the late 20th century but declining…
these incriminating documents relate to are not just any group of scientists. Professor Philip Jones of the CRU, his colleague Dr Keith Briffa, the US computer modeller Dr Michael Mann, of “hockey stick” fame, and several more make up a tightly-knit group who have been right at the centre of the last two reports of the UN’s Intergovernmental Panel on Climate Change (IPCC). On their account, as we shall see at this week’s Copenhagen conference, the world faces by far the largest bill proposed by any group of politicians in history, amounting to many trillions of dollars.
You’d think that such egregious behavior would have been exposed long before this. The elimination of the Medieval Warm Period by these fraudsters was in its way a cry for help, one that went mostly unheeded until now.
