The Earth experienced unprecedented recorded climate extremes during the decade 2001-2010, according to the World Meteorological Organisation.
Its report, The Global Climate 2001-2010, A Decade of Climate Extremes, analysed global and regional trends, as well as extreme events such as Hurricane Katrina, floods in Pakistan and droughts in the Amazon, Australia and East Africa.
The decade was the warmest for both hemispheres and for both land and ocean surface temperatures. The record warmth was accompanied by a rapid decline in Arctic sea ice, and accelerating loss of mass from the Greenland and Antarctic ice sheets and from glaciers.
