Global temperature highlights: November

  • The combined average temperature over global land and ocean surfaces during November tied with 2008 as the seventh highest for the month, at 1.17°F (0.65°C) above the 20th century average. The margin of error associated with this temperature is ±0.13°F (0.07°C). This ends a streak of three consecutive months with a record warm monthly global temperature.

  • The global land temperature was the 13th highest on record for November, at 1.46°F (0.81°C) above the 20th century average. The margin of error is ±0.20°F (0.11°C). Warmer-than-average temperatures were evident over most of the global land surface, except for most of North America, parts of southwest Asia, and a few isolated areas of northern Russia.
  • Neither El Niño nor La Niña was present across the central and eastern equatorial Pacific Ocean during November 2014. NOAA’s Climate Prediction Center estimates there is a 65 percent chance that El Niño will be present during the Northern Hemisphere winter and last into the Northern Hemisphere spring 2015.
  • The combined average temperature over global land and ocean surfaces for September–November was the highest on record for this period, at 1.26°F (0.70°C) above the 20th century average of 57.1°F (14.0°C), surpassing the previous record set in 2005 by 0.02°F (0.01°C). The margin of error associated with this temperature is ±0.16°F (0.09°C).
  • The global land temperature was the ninth highest for September–November on record, at 1.62°F (0.90°C) above the 20th century average of 48.3°F (9.1°C). The margin of error is ±0.31°F (0.17°C). Much of southern Australia was record warm, as was much of southern South America, the west coast of the United States, Far East Russia, and parts of southern Europe extending into northwestern Africa.
  • The average Arctic sea ice extent for November was 4.00 million square miles, 240,000 square miles (5.7 percent) below the 1981–2010 average and the ninth smallest November extent since records began in 1979, according to the National Snow and Ice Data Center. Sea ice extent was below average on the Pacific side of the Arctic and near-average on the Atlantic side.
  • Antarctic sea ice during November was 6.42 million square miles, 130,000 square miles (2.0 percent) above the 1981–2010 average. This was the eighth largest November Antarctic sea ice extent on record.
  • The first 11 months of 2014 was the warmest such period on record, with a combined global land and ocean average surface temperature of 1.22°F (0.68°C) above the 20th century average of 57.0°F (13.9°C), surpassing the previous record set in 2010 by 0.02°F (0.01°C). The margin of error is ±0.18°F (0.10°C). 2014 is currently on track to be the warmest year on record if the December global temperature is at least 0.76°F (0.42°C) above its 20th century average.
