Global temperatures in 2011 have not been as warm as the record-setting values seen in 2010 but have likely been warmer than any previous strong La Niña year, based on preliminary data from data sources compiled by the World Meteorological Organisation (WMO). The global combined sea surface and land surface air temperature for 2011 (January–October) is currently estimated at 0.41°C ± 0.111°C (0.74°F ± 0.20°F) above the 1961–1990 annual average of 14.00°C/57.2°F.
