Earth has its warmest November on record

December 17, 2013

An astonishing warm spell over Russia, up to 14 degrees F above normal, helped Earth achieve its warmest November on record.

Global temperatures were 1.4 degrees F above the 20th century average, 0.05 degrees F above the previous record from 2004 according to NOAA’s National Climatic Data Center.

“Much of southern Russia, north west Kazakhstan, south India, and southern Madagascar were record warm,” the National Climatic Data center writes. “Some areas of the Urals, Siberia, south of the Far East region, and on the Arctic islands in the Kara Sea had temperatures that were more than 8°C (14°F) higher than the monthly average.”

While large parts of the globe were abnormally warm, cool pockets focused in northern Australia, parts of North America, southwest Greenland, and parts of the Southern Ocean near South America. The U.S. temperature was 0.3 degrees below normal in November.

The warm November globally helped boost the year-to-date ranking from 7th warmest on record (through October) to a tie for 4th warmest (with 2002).

NASA’s independent analysis of global temperatures also concluded November 2013 was the warmest on record.

November marked the 345 consecutive month of above normal temperatures globally. The last cooler than average month globally occurred in February, 1985 (almost 29 years ago).
