RICHARD A. MULLER
He had been a vigerous global warming skeptic for some theoretical reasons having to do with how the theormometers measured temperature. He and his daughter put together a project to examine most of the data and make what he thought was a proper analysis. A significant part of his funding came from the ultra-conservative billionaire, Charles Koch who also funded the anti-global warming Heartland Institute. However, after Muller and his daughter finished their analysis, he surprised most and angered Koch, with this statement. The data had changed his mind.
Richard A. Muller is an American physicist and emeritus professor of physics at the University of California, Berkeley. He was also a faculty senior scientist at the Lawrence Berkeley National Laboratory. In early 2010, Muller and his daughter Elizabeth founded the group Berkeley Earth, an independent 501(c)(3) non-profit aimed at addressing some of the major concerns of the climate change skeptics, in particular the global surface temperature record.
