Would even cosmology or evolutionary biology, say, prove "faultless" if hit with similar exposures?

Is the wrong question.

Why is no one asking if the climate deniers fake their evidence, lie, manipulate the public, whore for their rich benefactors, and other questions that might be of passing interest?

This is how you do a certain kind of PR - not by looking at the evidence, but by smearing the character of those involved.

It's completely predictable, and it's disappointing, but not entirely surprising, that the climate science camp has been put on the defensive, when there are so many possible offensive moves that could mitigate the impact of this.

But we won't get the offensive moves, because the climate scientists still think it's about the quality of the science - when it very much isn't.
