The BEST Project out of Berkeley,which was put together to reanalyze land temperature records in the wake of the CRU Hack to make sure that global warming really wasn't a communist hoax, did not get off to a good start. Funded by the Koch brothers, fronted by an elderly physicist named Richard Muller with an unfortunate tendency to spout off on fields in which he possesses no expertise, the whole thing looked like a denialist set-up. But, as Joe Romm points out, you can't the instrumental record into something it isn't. He quotes climatologist Ken Caldeira:
I have seen a copy of the Berkeley group’s draft paper, which of course would be expected to be revised before submission.
Their preliminary results sit right within the results of NOAA, NASA, and HadCRU, confirming that prior analyses were correct in every way that matters. Their results confirm the reality of global warming and support in all essential respects the historical temperature analyses of the NOAA, NASA, and HadCRU.
Their analysis supports the view that there is no fire behind the smokescreen put up by climate science deniers.
So there you have it.
