Global Temperature: November 2013, the record highest in the 134-year period of record
It is more than three years that monthly global temperature has registered anomalies, if compared with the 20th century average. In fact, The average temperature across global land and ocean surfaces during November 2013 was record highest for November in the 134-year period of record, at 0.78°C (1.40°F) above the 20th century average.
Most of the world's land areasexperienced warmer-than-average monthly temperatures, including much of Eurasia, coastal Africa, Central America, and central South America. Much of southern Russia, north west Kazakhstan, south India, and southern Madagascar 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. Overall, the globally-averaged temperature over land surfaces was the second highest for November in the 134-year period of record, at 1.43°C (2.57°F) above the 20th century average.
The November global ocean temperature in 2013 tied with 2009 as the third highest for November, at 0.54°C (0.97°F) above the 20th century average. Regionally, the tropical oceans (20°N–20°S) were 10th warmest on record for November, while the Northern and Southern Hemisphere oceans above 20° latitude (outside the tropics) both tied as second warmest, at 0.64°C (1.15°F) and 0.53°C (0.95°F) above their long-term averages, respectively.
September–November (Northern Hemisphere fall / Southern Hemisphere spring) was the second warmest such period across global land and ocean surfaces since records began in 1880, behind only 2005, at 0.68°C (1.22°F) above the 20th century average. 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 globally-averaged temperature across land and ocean surfaces for the first eleven months of 2013 (January–November) was 0.62°C (1.06°F) above the 20th century average, tying with 2002 as the fourth warmest January–November on record. The average global land temperature for this period also tied with 2002 as the fourth highest on record, at 0.98°C (1.82°F) above the long-term average, while the average global ocean temperature tied with 2006 as the eighth warmest in the 134-year period of record, at 0.48°C (0.86°F) above average.
