“Hockey Stick” scientist Mann’s letter in the WSJ

Michael Mann has been pilloried by climate change denialists for showing in a clear graphic form that the climate is as warm now as it has been in a thousand years. At the AGU this year, he pointed out that his critics have been refuted by numerous investigations, and mentioned a letter published today in the WSJ, which includes the statement: 

After my colleagues and I had our emails stolen and posted online in November 2009, attacks from climate contrarians were subsequently shot down by investigations from two universities, the National Science Foundation, two federal agencies and several media outlets. Contrarians declared that those institutions were part of an imagined global-warming conspiracy.

Meanwhile the hockey stick itself is beginning to look a little quaint: at the AGU this year, James Hansen hints that he will show that current global temps are the highest they've been in a million years.
