USATODAY.com: "After examining the satellite data, collected since 1979 by National Oceanic and Atmospheric Administration weather satellites, Carl Mears and Frank Wentz of Remote Sensing Systems in Santa Rosa, Calif., found that the satellites had drifted in orbit, throwing off the timing of temperature measures. Essentially, the satellites were increasingly reporting nighttime temperatures as daytime ones, leading to a false cooling trend. The team also found a math error in the calculations.
�Our hats are off to (them). They found a real source of error,� says atmospheric scientist John Christy of the University of Alabama at Huntsville, whose team produced the lower temperature estimates.
When examining the balloon data, Yale University researchers found that heating from tropical sunlight "
