Revisiting the Satellite Record Global warming skeptics have long pointed to satellite data showing cooling in the tropical atmosphere as evidence that either climate models or measurements of surface warming, or both, are unreliable. New research suggests, however, that it is the analysis of the satellite data that was wrong. mark for My Articles similar articles
