November 2013 Global Temperatures Highest on Record


NOAA: November global temperature highest on record



According to NOAA scientists, the globally-averaged temperature over land and ocean surfaces for November 2013 was the highest for November since record keeping began in 1880. It also marked the 37th consecutive November and 345th consecutive month (more than 28 years) with a global temperature above the 20th century average. The last below-average November global temperature was November 1976 and the last below-average global temperature for any month was February 1985.

Most areas of the world experienced warmer-than-average monthly temperatures, including: much of Eurasia, coastal Africa, Central America, central South America, parts of the North Atlantic Ocean, the south west Pacific Ocean, and the Indian Ocean. Much of southern Russia, northwest Kazakhstan, south India, southern Madagascar, parts of the central and south Indian Ocean, and sections of the Pacific Ocean were record warm. Meanwhile, northern Australia, parts of North America, south west Greenland, and parts of the Southern Ocean near South America were cooler than average. No regions of the globe were record cold.     

 

Global Highlights

  • The combined average temperature over global land and ocean surfaces for November 2013 was record highest for the 134-year period of record, at 0.78°C (1.40°F) above the 20th century average of 12.9°C (55.2°F).
  • The global land surface temperature was 1.43°C (2.57°F) above the 20th century average of 5.9°C (42.6°F), the second highest for November on record, behind 2010. For the global oceans, the November average sea surface temperature was 0.54°C (0.97°F) above the 20th century average of 15.8°C (60.4°F), tying with 2009 as the third highest for November.
  • The combined global land and ocean average surface temperature for the September–November period was 0.68°C (1.22°F) above the 20th century average of 14.0°C (57.1°F), the second warmest such period on record, behind only 2005.
  • The September–November worldwide land surface temperature was 1.08°C (1.94°F) above the 20th century average, the third warmest such period on record. The global ocean surface temperature for the same period was 0.52°C (0.94°F) above the 20th century average, tying with 2009 and 2012 as the fourth warmest September–November on record.
  • The combined global land and ocean average surface temperature for the year-to-date (January–November) was 0.62°C (1.12°F) above the 20th century average of 14.0°C (57.2°F), tying with 2002 as the fourth warmest such period on record.
