The Berkeley Earth Surface Temperature Study (BEST) has finally published its findings on the cause of recent global warming. This Koch-funded reanalysis of millions of temperature observations from around the world, “A New Estimate of the Average Earth Surface Land Temperature Spanning 1753 to 2011,” concludes:

… solar forcing does not appear to contribute to the observed global warming of the past 250 years; the entire change can be modeled by a sum of volcanism and a single anthropogenic [human-made] proxy.




The decadal land surface temperature from BEST average (black line), “compared to a linear combination of volcanic sulfate emissions (responsible for the short dips) and the natural logarithm of CO2 (responsible for the gradual rise) shown in red. Inclusion of a proxy for solar activity did not significantly improve the fit. The grey area is the 95% confidence interval.”

You may recall that back in July, Richard Muller, BEST’s Founder and Scientific Director, published aNY Times op-ed, “The Conversion of a Climate-Change Skeptic,” which concluded

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.
