The world suffered unprecedented climate extremes in the decade to 2010, from heatwaves in Europe and droughts in Australia to floods in Pakistan, against a backdrop of global warming, a United Nations report said on Wednesday.
Every year of the decade except 2008 was among the 10 warmest since records began in the 1850s, with 2010 the hottest, according to the study by the World Meteorological Organization (WMO). The number of daily heat records far outstripped lows.
It said many extremes could be explained by natural variations - freak storms and droughts have happened throughout history - but that rising emissions of man-made greenhouse gases also played a role.
"Rising concentrations of heat-trapping greenhouse gases are changing our climate, with far-reaching implications for our environment and our oceans, which are absorbing both carbon dioxide and heat," WMO Secretary-General Michel Jarraud said in a statement.
