NASA has released a new analysis of temperature change. The map shows temperature anomalies for 2000-2009 and 1970-1979 relative to a 1951-1980 baseline.

To conduct the analysis, NASA's Goddard Institute for Space Studies (GISS) uses "publicly available data from 6,300 meteorological stations around the world; ship-based and satellite observations of sea surface temperature; and Antarctic research station measurements."
"These three data sets are loaded into a computer analysis program—available for public download from the GISS web site—that calculates trends in temperature anomalies relative to the average temperature for the same month during 1951-1980," according to NASA.
