Anthropogenic global warming is not a theory being put forth, it's the logical consequence of physical principles that are well established. It's not at all like Einstein proposing General Relativity. What (serious) people are arguing over is details of the analysis and the magnitude of effects. Those uncertainties are real, but it is no different from any other scientific debate.<p>The article I linked, if you actually read it, does not advocate skepticism at all. It claims in no uncertain language that the greenhouse effect violates all kinds of established principles, but it's hogwash. I saw that article cited in The Nation, and it aggravated me enough that I wrote up a response (<a href="http://www.familjenjonsson.org/patrik/research/greenhouse" rel="nofollow">http://www.familjenjonsson.org/patrik/research/greenhouse</a>, if you are interested).
