2011 is likely to be the world's tenth warmest year on record. This is despite a particularly strong La Niña which usually acts to dampen global temperatures, according to the World Meteorological Organisation (WMO). The WMO has released its summary and status of the global climate and weather for 2011 at the United Nations Framework Convention on Climate Change talks taking place in Durban South Africa.
"Concentrations of greenhouse gases in the atmosphere have reached new highs. They are very rapidly approaching levels consistent with a 2 to 2.4 degree Centigrade rise in average global temperatures which scientists believe could trigger far reaching and irreversible changes in our Earth, biosphere and oceans," said WMO Secretary-General Michel Jarraud.
