Even though this year isn't yet in the books, 2013 is on track to be the seventh-warmest year since modern temperature records began in 1850, the World Meteorological Organization reported today in conjunction with the United Nations-led global climate talks underway this week in Poland.
Global land and sea surface temperatures were about 0.86 degrees Fahrenheit above the 1961-1990 average for the period between January and September of this year, tying them with the same time frame from 2003 as the seventh-warmest such period on record.
Warmer temperatures were most extreme in Australia in 2013, the report notes, in contrast with 2012 when the United States experienced much of the world's record high annual temperatures.
Temperatures this year are in line with the trend since 2000, said WMO Secretary-General Michael Jarraud, adding that the 2000 to 2010 period was the warmest decade on record so far.
"All of the warmest years have been since 1998 and this year once again continues the underlying, long-term trend," he added. "The coldest years now are warmer than the hottest years before 1998."
