Temperatures are Up

Feel warmer? Maybe not everywhere but global temperatures were the fifth highest on record for October. Meanwhile arctic sea ice doubles from last month, yet remains second lowest on record for October. The globally-averaged temperature for October 2012 was the fifth warmest October since record keeping began in 1880. October 2012 also marks the 36th consecutive October and 332nd consecutive month with a global temperature above the 20th century average.

Higher-than-average monthly temperatures were observed across much of Europe, western and far eastern Asia, northeastern and southwestern North America, central South America, northern Africa, and most of Australia. Meanwhile, much of northwestern and central North America, central Asia, parts of western and northern Europe, and southern Africa were notably below average.

The combined average temperature over global land and ocean surfaces for October tied with 2008 as the fifth highest for October on record, at 58.23°F (14.63°C) or 1.13°F (0.63°C) above the 20th century average. The margin of error associated with this temperature is ±0.22°F (0.12°C).

Higher-than-average monthly temperatures were most notable across Europe, western and far eastern Asia, northeastern and southwestern North America, central South America, northern Africa, and most of Australia, while temperatures were below average across much of northwestern and central North America, central Asia, parts of western and northern Europe, and southern Africa.

For the ocean, the October global sea surface temperature was 0.94°F (0.52°C) above the 20th century average of 60.6°F (15.9°C), tying with 2004 as the fourth highest on record for October. The margin of error is ±0.07°F (0.04°C). The northwestern Atlantic Ocean and part of the north central Pacific Ocean temperatures were markedly higher than average, while much of the eastern and part of the western Pacific Ocean and much of the southern Atlantic Ocean were below average.

Then there is the average temperature across the United Kingdom was 2.3°F (1.3°C) below the 1981—2010 average, making it the coldest October since 2003!

During the first full month of the annual growth cycle, Arctic sea ice doubled in size after reaching its record smallest minimum in September. The October Arctic sea ice extent was 2.7 million square miles, 24.6 percent below average.

On the opposite pole, Antarctic sea ice extent declined rapidly after reaching its largest annual maximum extent on record. October Antarctic sea ice extent was 7.3 million square miles, 3.4 percent above average, and the third largest October ice extent on record.

So it goes.  Mostly warmer with isolated cold spots.
