People Seem to forget how important this is, that is why I want to remind them, this is a article from 07/29/2012.
When the best scientists, including some of the few skeptics among them, study the data–and study it carefully and thoroughly–they too recognize the truth. And that was certainly true in the case of Cal-Berkeley physics Professor Richard Muller when asked to chair the Berkeley Earth Surface Temperature (BEST) project, set up for global warming skeptics. Now he too is among the unqualified believers. The evidence is strong and persuasive. And neither wishing it were not true, nor political spin, nor self-interested business denials, can change the truth of it at all. It’s what the data and analysis tell us. nbcnews.com reports:
