Steve McIntyre of Toronto operates http://www.climateaudit.org/ as a hobby, essentially. I discovered the site accidentally a few years ago. Steve has waged an often lonely campaign to examine the accuracy of the data and methods behind the "consensus" view of climate change.

Steve has uncovered a whopper of an error, one that calls the "consensus" into question and the diligence of all those so-called scientists who shared the consensus. True scientific progress relies upon open sharing of experimental data--the inputs, the data, the environment, etc.--and the scientist's proposed theory is only considered proven if the experiment can be repeated successfully by any other scientist acting independently. Steve has fought to obtain the data and methods used by "the team", the scientists who Crazy Al relies on most to bolster his claim that we only have 10 years left to act. "The team" admitted an error that invalidated their claim for a hockey stick in Congressional testimony this year. Now NASA and their famed muzzled scientist (who's been muzzled into giving perhaps hundreds of tiresome interviews) admit a key error that calls more of the "consensus" view into question.
