Temperatures High and Low

Abstract

Satellite measurements show almost no temperature change since measurements began in 1979; in contrast, temperatures at Earth's surface are reported to have risen by 0.3Âo to 0.4ÂoC over the same period. In this Perspective, [Parker][1] discusses how papers by Santer et al . (page [1227][2]) and Gaffen et al . (page [1242][3]) shed some light on the reasons for this discrepancy, understanding of which is crucial for modeling climate, explaining and attributing climatic changes, and planning for future climate monitoring.
