koch-funded study finds 2.5 degree F. warming of land since 1750 is manmade

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 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.

1. Wonder How Long It Will Take The Koch Brothers To Bury This Study
