Mean global surface temperatures in November 2013 were the warmest on record according to the latest data from US agencies the National Oceanic and Atmospheric Administration (NOAA) and NASA.
According to NOAA scientists, the globally averaged temperature over land and ocean surfaces for November 2013 was the highest for November since record keeping began in 1880. NOAA reports an anomaly, or variation against the long term average from 1951 to 1980, of +0.78oC. This is the largest November anomaly on record in the NOAA data series.
According to NASA, November notched up an anomaly, or variation to the long term average between 1951 and 1980, of +0.77oC. This is largest reported monthly anomaly since the earliest records in the data series used by NASA. The previous record was in November 2010 when the NASA records show an anomaly of 0.67oC.
According to NOAA, most areas of the world experienced warmer-than-average monthly temperatures, including most of Eurasia, Africa, and South America, plus parts of the North Atlantic Ocean, the southwest Pacific Ocean, and the Indian Ocean. Much of southern Russia, northwest Kazakhstan, south India, southern Madagascar, parts of the central and south Indian Ocean, and sections of the Pacific Ocean were record warm. Meanwhile, northern Australia, parts of North America, southwest Greenland, and parts of the Southern Ocean near South America were cooler than average. No regions of the globe were record cold.
November also marked the 37th consecutive November and 345th consecutive month (more than 28 years) with a global temperature above the 20th century average, according to NOAA. The last below-average November global temperature was November 1976 and the last below-average global temperature for any month was February 1985.
