Climate Change Skeptic Makes 'Total Turnaround'


One of the most-outspoken global warming deniers has reversed his stance on climate science, saying it is indeed human-made. The news that physicist Richard Muller had gone public with his reversal was even more surprising because his Berkeley Earth Surface Temperature project is heavily funded by the climate change-denying billionaire Koch brothers.

Muller said that his new opinion stems from his own Koch-funded project, whose meticulous work, he said, led to the only explanation for rising temperatures was human activity.

In an Op-Ed in the New York Times, Muller was blunt about his reversal.

“Three years ago, I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming," Muller wrote."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.”

The Los Angeles Times said that Muller called his stance a total turnaround. The newspaper also reported comments from leading climate expert Michael Mann of Penn State on his Facebook page after the news.

“There is a certain ironic satisfaction in seeing a study funded by the Koch Brothers—the greatest funders of climate change denial and disinformation on the planet—demonstrate what scientists have known with some degree of confidence for nearly two decades: that the globe is indeed warming, and that this warming can only be explained by human-caused increases in greenhouse gas concentrations."
