Last month was one of the warmest Novembers ever in Philadelphia, but globally it was the coolest November since 2000, according to the government.
The National Oceanic and Atmopsheric Administration reported this afternoon that last month was about a half-degree cooler worldwide than November 2011.
But the combined land-and-sea temperature still ranked as the 12th warmest for a November in the period of record that dates to 1880.
Of the 11 Novembers ahead of this one, 10 have occurred in the 21st Century, with 1997 slipping in at No. 10.
Acrtic sea-ice extent was the third-lowest for a November since observations began in 1979, and marked the 126th consecutive month of below-average sea ice.
