Geneva, 16 December 2008 (WMO) The year 2008 is likely to rank as the 10th warmest year on record since the beginning of the instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO). The global combined sea-surface and land-surface air temperature for 2008 is currently estimated at 0.31°C/0.56°F above the 1961-1990 annual average of 14.00°C/57.2°F. The global average temperature in 2008 was slightly lower than that for the previous years of the 21st century due in particular, to the moderate to strong La Niña that developed in the latter half of 2007.
The Arctic Sea ice extent dropped to its second-lowest level during the melt season since satellite measurements began in 1979. Climate extremes, including devastating floods, severe and persistent droughts, snow storms, heatwaves and cold waves, were recorded in many parts of the world.
