writes "The results of the Berkeley Earth Surface Temperature are in and Richard Muller, the study's director (formerly an AGW skeptic) declares, '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.'
The study was funded by the Folger Fund, the Lawrence Berkeley National Laboratory, the Fund for Innovative Climate and Energy Research (created by Bill Gates), the Bowes Foundation, the Koch Foundation, and the Getty Foundation."Link to Original Source
