The map shows global temperature anomalies in 2008 compared to the 1950-1980 baseline period. Below-average temperatures are shown in blue, average temperatures are white, and above-average temperatures are red. (Gray indicates no data.) Most of the world was either near normal or warmer than normal. Eastern Europe, Russia, the Arctic, and the Antarctic Peninsula were exceptionally warm (1.5 to 3.5 degrees Celsius above average). The temperature in the United States in 2008 was not much different than the 1951-1980 mean, which makes 2008 cooler than all of the previous years this decade. Large areas of the central and eastern Pacific Ocean were cooler than the long-term average, linked to a La Niña episode that began in 2007.
