“The decadal land-surface average temperature using a 10-year moving average of surface temperatures over land. Anomalies are relative to the Jan 1950 – December 1979 mean. The grey band indicates 95% statistical and spatial uncertainty interval.” A Koch-funded reanalysis of 1.6 billion temperature reports finds that “essentially all of this increase results from the human emission of greenhouse gases.”
he Berkeley Earth Surface Temperature Study (BEST) is poised to release its findings next week on the cause of recent global warming.
UPDATE (9 pm): A NY Times op-ed by Richard Muller, BEST’s Founder and Scientific Director, has been published, “The Conversion of a Climate-Change Skeptic.”
Here is the money graf:
CALL me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.
