 Some of it's also natural, like I said, rebounding from the little ice age. But the problem with science is they don't look at the other two factors. They refuse to, no matter how much we talk about it. They don't want to look at natural variability. They don't want to look at UHI. They say, ah, it's insignificant. Well, they're wrong. I mean, I have documented this in places all over the United States. Reno, Nevada has the largest UHI signature of any city in the United States.
