A Converted Skeptic July 30, 2012 : 6:44 PM

Although his research study – partially funded by one of the Koch brothers – has not yet been printed in a peer-reviewed journal, Berkeley scientist Richard Muller writes in The New York Times:

“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.”
