The NASA Goddard Institute for Space Studies (GISS) has released an image showing the global temperature anomalies for May 2010. The northern polar regions showed a dramatic increase in warmth, while cooler-than-normal conditions occurred in parts of western United States, and southern South America.

This color-coded map shows global surface temperature anomalies for May 2010 compared to average temperatures for the same time of year from 1951 to 1980. Above-normal temperatures appear in shades of red, and below-normal temperatures appear in shades of blue. Gray areas indicate areas of insufficient data.
