A tale of deceit and malfeasance

We've written about the 'hockeystick graph' before, in December 2006. Back then we wrote:
This past week not a single night went by the the Dutch 8 o'clock news did not carry a story linking distaster to global warming and linking global warming to human activity (as a given). Yet there are some serious questions ignored and actively downplayed that would put a serious dent in the assertions of the man-made character of global warming. Just read the intriguing story about the debunking of the Hockey Stick graph by McKitrick and McIntyre.
Yet the hockey stick made it into the IPCC reports and is still used as THE proof that humans wreak havoc on the atmosphere and global temperatures. But it is a lie.

Bishop Hill has taken it upon himself to write a concise and (not very) short history of the hockeystick graph, how it came to be, how it got published despite legitimate scientific objections and how it ended up in the IPCC reports, despite its abyssmal quality. Writes the Bishop about the authors of a paper claiming to prove the hockeysticks reality:
That the statistical foundations on which they had built this paleoclimate castle were a swamp of misrepresentation, deceit and malfeasance was, to Wahl and Amman, an irrelevance. For political and public consumption, the hockey stick still lived, ready to guide political decision-making for years to come.
If you read just one thing today, this is the one.
