A heartwarming story of scientific integrity on a wingnut's dime

A team of UC Berkeley physicists and statisticians that set out to challenge the scientific consensus on global warming is finding that its data-crunching effort is producing results nearly identical to those underlying the prevailing view.

The Berkeley Earth Surface Temperature project was launched by physics professor Richard Muller, a longtime critic of government-led climate studies, to address what he called "the legitimate concerns" of skeptics who believe that global warming is exaggerated.

But Muller unexpectedly told a congressional hearing last week that the work of the three principal groups that have analyzed the temperature trends underlying climate science is "excellent.... We see a global warming trend that is very similar to that previously reported by the other groups."

The hearing was called by GOP leaders of the House Science & Technology committee, who have expressed doubts about the integrity of climate science. It was one of several inquiries in recent weeks as the Environmental Protection Agency's efforts to curb planet-heating emissions from industrial plants and motor vehicles have come under strenuous attack in Congress.

Muller said his group was surprised by its findings, but he cautioned that the initial assessment is based on only 2% of the 1.6 billion measurements that will eventually be examined.

The Berkeley project's biggest private backer, at $150,000, is the Charles G. Koch Charitable Foundation. Oil billionaires Charles and David Koch are the nation's most prominent funders of efforts to prevent curbs on the burning of fossil fuels, the largest contributor to planet-warming greenhouse gases.
