Global warming measurements confirmed

“When we began our study, we felt that skeptics had raised legitimate issues, and we didn’t know what we’d find,” Muller wrote. “Our results turned out to be close to those published by prior groups. We think that means that those groups had truly been careful in their work, despite their inability to convince some skeptics of that.”
In other words, the deniers’ claims about the alleged sloppiness or fraudulence of climate science are wrong. Muller’s team, the Berkeley Earth Surface Temperature project, rigorously explored the specific objections raised by skeptics — and found them groundless.
Muller and his fellow researchers examined an enormous data set of observed temperatures from monitoring stations around the world and concluded that the average land temperature has risen 1 degree Celsius — or about 1.8 degrees Fahrenheit — since the mid-1950s.
This agrees with the increase estimated by the United Nations-sponsored Intergovernmental Panel on Climate Change. Muller’s figures also conform with the estimates of those British and American researchers whose catty e-mails were the basis for the alleged “Climategate” scandal, which was never a scandal in the first place.
The Berkeley group’s research even confirms the infamous “hockey stick” graph — showing a sharp recent temperature rise — that Muller once snarkily called “the poster child of the global warming community.” Muller’s new graph isn’t just similar, it’s identical.
Muller found that skeptics are wrong when they claim that a “heat island” effect from urbanization is skewing average temperature readings; monitoring instruments in rural areas show rapid warming, too. He found that skeptics are wrong to base their arguments on the fact that records from some sites seem to indicate a cooling trend, since records from at least twice as many sites clearly indicate warming. And he found that skeptics are wrong to accuse climate scientists of cherry-picking the data, since the readings that are often omitted — because they are judged unreliable — show the same warming trend.
