The conversion of a climate-change skeptic

Don't expect extremist ideologues like Thom Tillis and Pat McCrory to give a damn, but it's good to see there are still some adults who are capable of critical thinking.

Call me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.
