What the AP reported:
Kerry Emanuel, an MIT professor who had feuded with Gray over global warming, said Gray has wrongly “dug (his) heels in” even though there is ample evidence that the world is getting hotter.
What a google search found within thirty seconds.:
Q: … is global warming behind this increase in hurricanes?
Gray: I am very confident that itâ€™s not. I mean we have had global warming. Thatâ€™s not a question. The globe has warmed the last 30 years, and the last 10 years in particular.
Update: South Dakota Politics agrees.
