The study of the world's surface temperatures by Richard Muller was partially bankrolled by a foundation connected to global warming deniers. He pursued long-held skeptic theories in analyzing the data. He was spurred to action because of "Climategate," a British scandal involving hacked emails of scientists.
Yet he found that the land is 1.6 degrees Fahrenheit (1 degree Celsius) warmer than in the 1950s. Those numbers from Muller, who works at the University of California, Berkeley, and Lawrence Berkeley National Lab, match those by the National Oceanic and Atmospheric Administration and NASA.
