The University of Alabama at Huntsville has released the March 2010 spatial plot of the lower troposphere temperature anomalies as monitored by satellite (thanks for John Christy, Roy Spencer, and Phillip Gentry for providing this to us!)
As the UAH group reports, March 2010 was third warmest month in the 31-year temperature record with the global anomaly since Nov. 16, 1978 of +0.13 C per decade. The processed temperature data is available on-line at: vortex.nsstc.uah.edu/data/msu/t2lt/uahncdc.lt
The spatial map of the anomalies is given below which shows the continued large variations between regions, with the higher latitudes of North America particularly warm.
The substantial spatial variations illustrates yet again why we need a regional focus to climate change, and why a global average surface temperature anomaly is an inadequate metric to monitor climate variability and change.
