Gary Thompson is a climate change denier (of some stripe) who has at least on two occasions published climate change denialist articles for the wingnut website American Thinker. The website unfortunately provides no more information about him, and we have thus been unable to locate any reliable background (his name is hardly unique). But the articles themselves are instructive. “The AGW Smoking Gun”, for instance, does cites peer-reviewed papers, but what he calls “analyzing” e.g. graphs is not analyzing but rather quickly eyeballing graphs while dismissing peer-reviewed data analysis to lead himself to the opposite conclusion compared to the authors of the papers in question (“Our results provide direct experimental evidence for a significant increase in the Earth’s greenhouse effect that is consistent with concerns over radiative forcing of climate”). So instead of disproving the enhanced greenhouse effect, Thompson’s article merely provides, instead, further evidence for the Dunning-Kruger effect, and/or for the pernicious influence of bias . For more detailed criticisms of the article, this one is helpful.
Diagnosis: Thompson really is a good example of denialism at work – he is certainly a smart guy, and certainly a far cry e.g. from some of the wild-eyed creationists we have covered when it comes to being thoughtful and measured. But bias and a little knowledge can fell the smartest, and Thompson is not the smartest.
