The latest satellite temperature data are in. I have provided a graphic for the two main data sets by the University of Alabama at Huntsville and that by Remote Sensing Systems. Each plot shows the lower tropospheric temperature for the globe, the tropics and the northern and southern hemispheres. I have included a loess smoothing with three spans to give the reader an idea of trends in the data. The loess should not be regarded as a definitive proof of a trend as more robust statistics should be used to identify any trends. Indeed, Analysis of Variance does indicate that the 2000s are significantly warmer than either the 1980s or 1990s.
