Trump does not believe in man-made global warming, and attributes any warming as may be occurring to natural cycles that could reverse at any time.
HUGH HEWITT: “Do you believe that the temperature of the Earth is increasing, and what would you do if you do believe that vis-a-vis global climate change?”
DONALD TRUMP “Well, first of all, I'm not a believer in global warming, I'm not a believer in man-made global warming. It could be warming, and it's gonna start to cool at some point, and you know, in the early – in the 1920s, people talked about global cooling. I don't know if you know that or not. They thought the Earth was cooling. Now it's global warming. And, actually, we've had times where the weather wasn't working out, so they changed it to 'extreme weather' and they have all different names, so that it fits the bill.
But the problem we have, if you look at our energy costs and all of the things that we're doing to solve a problem that I don't think in any major fashion exists. I mean, Obama thinks it's the number one problem of the world today, and I think it's very low on the list. So I am not a believer, and I will – unless somebody can prove something to me. I believe there's weather, I believe there's change, and I believe it goes up, and it goes down, and it goes up again, and it changes depending on years and centuries. But I am not a believer, and we have much bigger problems.”
