Richard Muller, who directed a Koch-funded climate change project, has undergone a 'total turnaround' on his stance on global warming, which he now admits is caused by human activity.
The verdict is in: Global warming is real and greenhouse-gas emissions from human activity are the main cause.
This, according to Richard A. Muller, professor of physics at the University of California, Berkely, a MacArthur fellow and co-founder of the Berkeley Earth Surface Temperature project.
The United Nations Intergovernmental Panel on Climate Change and hundreds of other climatologists around the world came to such conclusions years ago, but the difference now is the source: Muller is a long-standing, colorful critic of prevailing climate science, and the Berkeley project was heavily funded by the Charles Koch Charitable Foundation, which, along with its libertarian petrochemical billionaire founder Charles G. Koch, has a considerable history of backing groups that deny climate change.
In an opinion piece in Saturday’s New York Times titled “The Conversion of a Climate-Change Skeptic,” Muller writes:
“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.”
