Row over climate 'hockey stick'

"A row has erupted over one of the most provocative symbols of global warming - the iconic "hockey stick" graph. This record of Northern Hemisphere temperature variation in the last 1,000 years shows a recent warming trend apparently linked to human activities. New work in the journal Geophysical Research Letters questions its validity, challenging the way it was originally put together. Other scientists say the work simply highlights a technical issue." Has anyone read State of Fear by Michael Crichton? (I know Mojo has) It talks about bias in scientific results and the importance of staying objective when looking at data like this. It's a really good book, even though some people have been attacking it because they claim it is denying global warming, but really it is just saying that we have far too little data to make some of the conclusions that we are, and if we really want to solve the problem we have to figure out how it is actually happening first.
