The Infamous Hockey Stick

McKitrick's discussion of flaws with the Mann Hockey Stick, which has been the poster child for global warming for the last 7 years. The interesting points are that the series gets it's oomph from the use of a bristlecone pine dataset that "could not be used as temperature proxies" according to the authors; IPCC does not publish plots from thousands of borehole data which show the mideval warm period (Mann's does not); and, the methodology used to generate the hockey stick seems a bit flawed.

Whether you believe or not, this is a good read. It is also a good read for those who may be interested in seeing how far peer review and the scientific method have progressed.
