DescriptionNovember 28, 2009

Michael Mann, one of the country’s leading climatologists, has coauthored a major new review and analysis of climate science since the 2007 IPCC report. Mann, Director of Pennsylvania State University’s Earth System Science Center, is much attacked by the anti-scientific disinformers because of his work on the paleoclimate “hockey stick” reconstructions of temperature over the past couple of millennia. Contrary to what the disinformers continue to say, however, the hockey stick was essentially vindicated by the National Academy of Sciences (see NAS Report and RealClimate.org).

As noted, Mann has been a primary target of the disinformers because of the hockey stick. Yet even more important than the fact that the original analysis was defensibly correct, is that the conclusions were correct [which could be true even if the analysis had flaws in it]. Is the planet now as hot (or hotter) than it has been in a millenium? Try two millennia (see “Sorry deniers, hockey stick gets longer, stronger: Earth hotter now than in past 2,000 years“). See also “Human-caused Arctic warming overtakes 2,000 years of natural cooling, ’seminal’ study finds.” That’s why climatologist and one-time darling of the contrarians Ken Caldeira said last month, “To talk about global cooling at the end of the hottest decade the planet has experienced in many thousands of years is ridiculous.”

Now Mann is being attacked again, again primarily by those misrepresenting his work and what he has written. You can find excellent explanations of many of those emails and the issues they raise at RealClimate (here). Here are Mann’s comments on the hacked emails:
