Manzi weighs in on "Climategate." His sane point:

The root problem here is not the eternal perfidy of human nature, but the fact that we can’t run experiments on history to adjudicate disputes, which makes this less like chemistry or physics than like economics or political science.

In human terms, the scandal is obviously a PR disaster for those who believe that climate reconstruction is “science” in the sense we normally use the term, but what it does not change is the basic physics of how CO2 molecules interact with radiation. As I have always argued, this is the real basis for rational concern about greenhouse-gas emissions, and is a key reason that all the major national scientific academies agree that the greenhouse effect is a real risk. Recognizing this risk, however, does not entail accepting the political conclusion that we need laws to radically reduce emissions at enormous cost.
