Global Highlights [maybe wanna start calling these downlights]

  • The combined global land and ocean average surface temperature for November 2010 was 0.69 °C (1.24 °F) above the 20th century average of 12.9 °C (55.2 °F). This was the second warmest such period on record. 2004 was the warmest November on record.
  • The combined global land and ocean average surface temperature for fall (September–November) 2010 was the sixth warmest on record for the season, 0.58 °C (1.04 °F) above the 20th century average of 14.0 °C (57.1 °F).
  • For the 2010 year-to-date (January–November), the combined global land and ocean surface temperature was 0.64 °C (1.15 °F) above the 20th century average—the warmest such period since records began in 1880.
  • The November 2010 Northern Hemisphere land and ocean surface temperature was the warmest November on record, while the Southern Hemisphere land and ocean surface temperature was the 13th warmest November on record.
  • The November 2010 global land surface temperature was the warmest on record, at 1.52 °C (2.74 °F) above the 20th century average, while the November global ocean temperature tied with 1987 and 2008 as the tenth warmest on record, at 0.39 °C (0.70 °F) above average.
  • The January–November 2010 Northern Hemisphere land surface temperature was the second warmest such period on record, while the Southern Hemisphere was the fourth warmest on record.

Introduction

Temperature anomalies for November 2010, September–November 2010, and January–November 2010 are shown on the dot maps in this section. The dot maps on the left provide a spatial representation of anomalies calculated from the Global Historical Climatology Network (GHCN) dataset of land surface stations using a 1961–1990 base period. The dot maps on the right are 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.

November
 
The combined global land and ocean surface temperature for November 2010 was the second warmest November, behind 2004, since global temperature records began in 1880. The combined global land and ocean temperature was 0.69 °C (1.24 °F) above the 20th century average of 12.9 °C (55.2 °F). The combined land and ocean surface temperature for November in the Northern Hemisphere was the warmest on record, while the combined land and ocean surface temperature in the Southern Hemisphere ranked as the 13th warmest such period on record. The globally averaged land temperature was the warmest on record, at 1.52 °C (2.74 °F) above the 20th century average of 5.9 °C (42.6 °F). The Northern Hemisphere November land temperature was also the warmest on record, while the Southern Hemisphere land temperature ranked as the 21st warmest on record. More than two-thirds of the Earth's land mass is located in the Northern Hemisphere.
