Richard Muller On Reconfirmation Of Temperature Data

NPR Science Friday hosts Berkeley professor Richard Muller whose Berkeley Earth Surface Temperature project investigated whether measured temperature data collected and reported by climate scientists was flawed. His conclusion is that the previously measured data faithfully records that the earth has been warming and that humans are primarily responsible for the temperature increase:

FLATOW: So tell us about your change of mind and heart about this issue.

MULLER: Well, if you had asked me a year ago, I might have said I didn't know whether there was global warming at all. But we had begun a major study, scientific reinvestigation. We were addressing what I consider to be legitimate criticisms of many of the skeptics.

But about nine months ago, we reached a conclusion that global warming was indeed taking place, that all of the effects that the skeptics raised could be addressed, and to my surprise, actually, the global warming was approximately what people had previously said.

It came as a bigger surprise over the last three to six months when our young scientist, Robert Rhode, was able to adopt really excellent statistical methods and push the record back to 1753. With such a long record, we could then separate out the signatures of solar variability, of volcanic eruptions, of El Nino and so on. And actually, to my surprise, the clear signature that really matched the rise in the data was human carbon dioxide and other greenhouse gases. It just matched so much better than anything else. I was just stunned.

Prof. Muller also talks about the urgent need for a policy that provides incentives and financial assistance to switch to natural gas thus cutting down on the need to burn coal. Clean fracking is his rallying point!

Also the Guardian has a long article on Richard Muller and his work.
