Temperature anomalies for February 2010 and December 2009 - February 2010 are shown on the dot map, which is a product of a merged land surface and sea surface temperature (SST) anomaly analysis developed by Smith et al. (2008). For the merged land surface and SST analysis, temperature anomalies with respect to the 1971-2000 average for land and ocean are analyzed separately and then merged to form the global analysis.

  • The combined global land and ocean average surface temperature for February 2010 was 0.60°C (1.08°F) above the 20th century average of 12.1°C (53.9°F). This is the sixth warmest such value on record.
  • The combined global land and ocean average surface temperature for December 2009 – February 2010 was the fifth warmest on record for the season, 0.57°C (1.03°F) above the 20th century average of 12.1°C (53.8°F).
  • For the year to date, the combined global land and ocean surface temperature of 12.7°C (54.9°F) was the fifth warmest January-February period on record. This value is 0.60°C (1.08°F) above the 20th century average.
  • The worldwide ocean surface temperature for February 2010 was the second warmest on record for February, 0.54°C (0.97°F) above the 20th century average of 15.9°C (60.6°F).
  • The seasonal (December 2009 – February 2010) worldwide ocean surface temperature was also the second warmest on record, 0.54°C (0.97°F) above the 20th century average of 15.8°C (60.5°F).
  • In the Southern Hemisphere, both the February 2010 average temperature for land areas and the Hemisphere as a whole (land and ocean surface combined), represented the warmest February on record. The Southern Hemisphere ocean temperature tied with 1998 as the warmest February on record.
