Earth Headed For its Hottest Year on Record After a Record-Warm September

September 2014 was Earth's warmest September on record, the period January - September was tied with 1998 and 2010 as the warmest first three-quarters of any year on record, and the past 12 months--October 2013 through September 2014--was the warmest consecutive 12-month period among all months since records began in 1880, said NOAA's National Climatic Data Center (NCDC) today. NASAalso rated September 2014 as the warmest September on record. If 2014 maintains the same temperature departure from average for the remainder of the year as was observed during January - September, it will be the warmest calendar year on record. September is the fourth time NOAA has ranked a 2014 month as the warmest on record; May, June, and August 2014 were also the warmest such months on record.
