Steve Mcintyre is an interesting guy. His hobby is to check the data, statistics, and models published in climate science articles. As far as I know his work is quality, at least several of his corrections have found their way into mainstream climate records. The fact that he has been involved in so many tooth-and-nail fights to obtain the data he seeks, often being flatly denied, ought to concern anyone who cares about the veracity of the claims of climate scientists and activists, as well as anyone with a vested interest in a political system that looks poised to spend trillions of dollars on climate policy over the next decade.

You can check out his blog here: http://www.climateaudit.org/. But be warned, it's not political at all. If you don't have a head for data series and regression models, you'll be put to sleep.

The amount of bad scientific practices and obfuscation that this one man has uncovered is staggering (scientists cherry-picking data for a paper and then refusing to provide the whole data set seems a common complaint). However, as good citizens we must believe that the thousands of papers he has not gotten around to checking are perfectly valid. To do otherwise is to be painted with the label of "heretic".

In the end, it is the poor treatment of the scientific process by scientists and activists, as well as the religion-like enforcement of agreement, that causes me to hold onto my green skepticism. I'm not sure that climate change won't Kill Us All, but I am not convinced by those that do think so.

edit: One final cause of my green skepticism is the fact that so many highly-publicized predictions made by environmentalists in the past, many of whom held PHDs, have been wrong. But more importantly, they have always been wrong in one direction, the direction of overstating the environmental damage done by human activity. The environmentalists of the 1960s foresaw a world that would undergo multiple environmental holocausts by the 1980s, which of course never came to pass.

While the quality of past predictions has no direct bearing on the quality of current predictions, indeed one might even assume that modern predictions are of higher quality given more advanced methods and greater funding, it does make me skeptical of any would-be green Nostradamus, at least until one establishes a good track record of predicting the future.
