I also see a similarity to string theory -- no physical evidence, just a "consensus" of opinion among the in-group of scientists at the elite schools who control funding and appointments, as well as an appeal to mathematical models as the main argument, and a disparagement of the scientists who disagree (some of whom are quite accomplished, as is the case with global warming skeptics as well).
The sociology of the two areas, global warming and string theory, is distressingly similar.
