During the September to November period, record highs were reported from both hemisphere, with no record cold temperatures reported anywhere

SUMMIT COUNTY — Even without an El Niño, the globally average land and sea surface temperature was the fifth-highest on record, at 1.21 degrees above the average since record-keeping started in 1880.
Global November temperatures have been above average for 36 years in a row, and the 333d month in a row with a global temperature above the 20th century average, according to the National Climatic Data Center, which released its monthly summary today.
The warmest areas were in far eastern Russia, Australia, the central and western United States, northern Africa, and most of Europe and western Asia. All of South America and almost the entire African continent — two huge land masses — were warmer than average.
Cooler than average readings were reported in central Asia, Alaska, much of western and central Canada, and the eastern United States were most notably cooler than average.
For the year to date, the NCDC reported record to near-record warmth over land from April to September and warmer-than-average global ocean temperatures in the eastern equatorial Pacific Ocean.
For the fall season, September to November, seasonal temperature across the world’s land and ocean surfaces were the second warmest on record behind 2005, at 0.1.21 degrees above the 20th century average.
Globally, the average land surface temperature was the third warmest September–November on record, behind 2005 and 2010. The Southern Hemisphere spring temperature was record warm, while the average Northern Hemisphere fall land temperature was fifth warmest.
Record high temperatures for the period were observed in parts of both hemispheres, including the southwestern United States, part of northern Africa and southern Europe, regions in far eastern Russia, part of north central Australia, and swaths of central and northern South America. No seasonal record cold temperatures were observed during this period.
With ENSO-neutral conditions present during all three months in the eastern and central equatorial Pacific Ocean, the globally-averaged ocean temperature was the fourth warmest for September–November, with record warm temperatures observed in parts of the northeastern and southern North Atlantic Ocean and parts of the western Indian Ocean.
As a result, the first 11 months of 2012 ranks as the eighth warmest such period on record, with a combined global land and ocean average surface temperature of 1.06 degrees above the 20th century average. It seems likely that 2012 will end up as one of the 10 warmest years on record.
Some parts of Europe were especially warm, including Austria, which reported an average November temperature 4.1 degrees above the 20th century average, with parts of the country up to 7 degrees above average.
