Last weekend the New York Times published an op-ed by University of California-Berkeley physics professor, Richard Muller, who said he has changed his professional opinion on the cause of global warming:
“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.”
Muller’s announcement sparked a media flurry throughout the week, and NPR’s Science Friday host, Ira Flatow, interviewed him today. You can listen to the audio recording HERE.
