Climate-Change Skeptic Changes His Mind

Here's the link.

A prominent climate-change denier now admits he was wrong. Astrophysics Professor Richard A. Muller says his doubts about previous climate change studies vanished after reviewing intensive research involving a dozen scientists. Muller now says global warming is real, and he goes a step further, saying humans are almost entirely the cause.

Global warming is real and is caused "almost entirely" by people, a University of California physicist and "converted" climate change skeptic says.

"Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming," UC Berkeley astrophysics Professor Richard A. Muller wrote in an opinion piece in The New York Times.

"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," he wrote.

Here's the funny part: His research was funded [in part] with $150,000 from the Charles G. Koch Charitable Foundation, which, along with its libertarian petrochemical billionaire founder, has historically backed groups that deny climate change.
