Well of course it is.

But scientific fact is scientific fact; attempts to censor or alter it to suit political leanings are silly and counterproductive.

And on climate change, as on evolution, the people who actually know what they're talking about--i.e., the scientists--have spoken. You don't get to argue that you don't like their conclusions, and you don't get to drag in talking heads--even PhDs from unrelated fields--to try to deny it. It's settled.
