Jarraud also said that the year 2009 would probably rank as the fifth warmest since accurate records were started in 1850.
The global combined sea surface and land surface air temperature for 2009 (January–October) is currently estimated at 0.44 degree centigrade above the 1961–1990 annual average of 14.00 degree centigrade. The current nominal ranking of 2009, which does not account for uncertainties in the annual averages, places it as the fifth-warmest year, the WMO says.
The decade of the 2000s (2000–2009) was warmer than the decade spanning the 1990s (1990–1999), which in turn was warmer than the 1980s (1980–1989).
The WMO noted that above-normal temperatures were recorded in most parts of the continents in 2009.
India had an extreme heatwave event during May, which caused 150 deaths. A heatwave hit northern China during June, with daily maximum temperatures above 40°C; historical maximum temperature records were broken for the summer in some locations.
