The fact is that Climate Scientists have been hoist on their own petard.
I don't recall climatologists calling Al Gore out on his ample waves of bullshit in An Inconvenient Truth, nor particularly his Nobel or Academy Award.
The leftish pap that glossed over the massive fallacies, misstatements, and begged questions in that movie had to be dug out by amateurs, on the web, dissecting the data and video on their own time.
Had a single, reputable scientist stood up and said "ok, Al, you've grossly and misleadingly overstated some stuff" *maybe* climatologists would have more credibility in the eyes of the public.
It's very easy and convenient to dismiss the - OFTEN - really stupid stuff said by the anti-global-warming crew. But climatologists inability to criticize their own field or data with any seeming sense of objectivity, to state clearly their guesses, and their propensity to say "the dog ate my homework" when pressed to provide the data has destroyed their moral position.
To suggest that climatologists, in particular, have any entitlement to credibility is nonsense. They've thrown it away themselves.
