I'd never really looked into the Mann graph with any seriousness, and started reading up on it today.
http://en.wikipedia.org/wiki/Hockey_stick_controversy
There's the wiki summary.

It's not the refuted nightmare that a lot of people claim. Apparently a mining executive and an economist the methodology. Some US senators got hold of it and called a senate inquiry.
The inquiry found that:
"The report agreed that there were statistical shortcomings in the MBH analysis, but concluded that they were small in effect."

This report was then refuted by some other statisticians not involved in the Congress (I should have said Congress not senate before) report, who declared it nonsense in a number of ways.

The whole wiki article is worth a read. It's quite well written and includes heaps of references.

The point is, that there have been contradictory views of the Hockey Stick; it has not been proved false outright as a lot of people suggest.

There's been a lot of tooing and froing over the result, which most recently, at a Statisticians Conference (which sounds Awesome!), was found to be 'most likely correct'.
"Similarly to the original study, this work found that recent increases in northern hemisphere surface temperature are anomalous relative to at least the past 1300 years, and that this result is robust to the inclusion or exclusion of the tree-ring dataset."

Sure you can interpret it anyway you like, but it seems A LOT of people support Mann's findings. One or 2, oppose it, but they're making a hell of a lot of noise about it.
