A little patience with statistics talk, and the mystery of some brittlecone pine data, are rewarded by a critique of the "hockey stick" data used to underpin too much talk about global warming (via Zacht Ei).

Today's temperatures are supposedly higher than at any time in the past thousand years. This claim is the central pillar of the Kyoto Protocol, which takes effect this month. It is largely based on the celebrated "hockey stick" graph of temperature history since the year 1000, published by Michael Mann and colleagues in 1998 and 1999. However, according to Canadian researchers Stephen McIntyre and Ross McKitrick, Mann's hockey stick is no more than a statistical artifact.

You may also want to refer to McKittrick et al.'s website at http://www.climateaudit.org. Although there's plenty of reason to be sceptical about their findings as well - not because one of them works for the oil industry, that's an ad hominem, but because their research still stands very much alone - I believe them to be a very valuable addition to the climate debate.
