Summary

Recent analyses show that the gap between the satellite temperature record and that of thermometers at the surface is more apparent than real. Although much was made of a 20-year-long satellite temperature record that showed a slight cooling, after considering the effects of El Niños and volcanoes and correcting for decay of the satellites' orbit, researchers are seeing not a cooling but a small warming, closer to that in surface records. Although the contrarians still aren't budging, a leading satellite analyst agrees that the satellite data are compatible with a slight warming trend because the discrepancy between satellite temperatures and model predictions of moderate greenhouse warming "isn't that large."
