According to NOAA scientists, the globally-averaged temperature for November 2012 marked the fifth warmest November since record keeping began in 1880. It also marked the 36thconsecutive November and 333rd consecutive month with a global temperature above the 20th century average. The last below-average November temperature was November 1976 and the last below-average temperature for any month was February 1985.. Most areas of the world experienced higher-than-average monthly temperatures, including far eastern Russia, Australia, the central and western United States, northern Africa, and most of Europe and western Asia. Meanwhile, central Asia, Alaska, much of western and central Canada, and the eastern United States were most notably cooler than average.



November 2012 Global Highlights

  • The average combined global land and ocean surface temperature for November 2012 was 0.67°C (1.21°F) above the 20th century average of 12.9°C (60.4°F). This is the fifth warmest November since records began in 1880. Including this November, the 10 warmest Novembers have occurred in the past 12 years.

  • The globally-averaged land surface temperature for November 2012 was the sixth warmest November on record, at 1.13°C (2.03°F) above average. The globally-averaged ocean surface temperature was also sixth warmest on record, at 0.50°C (0.90°F) above average.

  • ENSO-neutral conditions continued in the eastern equatorial Pacific Ocean during November 2012. Neutral conditions are expected to last through the Northern Hemisphere winter 2012/13 and into spring 2013.

  • The average combined global land and ocean surface temperature for September–November 2012 was 0.67°C (1.21°F) above the 20th century average of 14.0°C (57.1°F), marking the second warmest September–November on record, behind 2005.

  • The globally-averaged land surface temperature for September–November 2012 was the third warmest September–November on record, at 1.03°C (1.85°F) above average. The Southern Hemisphere land temperature was record warm for the period.

  • The combined global land and ocean average surface temperature for January–November 2012 was the eighth warmest such period on record, at 0.59°C (1.06°F) above the 20th century average.
