The story of Richard Muller is making the rounds this week. Muller is a scientist at UC Berkeley and was a climate change skeptic who was hired and in part funded by Koch Foundation (the right-wing, climate change denying, billionaire Koch brothers) to find out if "mainstream" scientist were wrong about climate change. But after doing the research, he concluded that global climate chagne is indeed real. He makes no mention of human induced climate change, but urges a reduction in green house gas emissions as a worthy endeavor.
"And now we have confidence that the temperature rise that had previously been reported had been done without bias."
