Global temperature breaks September record; ties record highest for January-September

The combined average temperature over global land and ocean surfaces reached a record high for September, at 0.72°C (1.30°F) above the 20^th century average of 15.0°C (59.0°F), according to  NOAA National Climatic Data Center (NCDC).

Additionally, the first nine months of 2014 (January–September) tied with 1998 as the warmest such period on record, with a combined global land and ocean average surface temperature 0.68°C (1.22°F) above the 20^th century average of 14.1°C (57.5°F), said NCDC.

If 2014 maintains this temperature departure from average for the remainder of the year, it will be the warmest calendar year on record. The past 12 months—October 2013–September 2014—was the warmest 12-month period among all months since records began in 1880, at 0.69°C (1.24°F) above the 20^th century average. This breaks the previous record of +0.68°C (+1.22°F) set for the periods September 1998–August 1999, August 2009–July 2010; and September 2013–August 2014.
