WMO: 2000-2010 "Unprecedented" - Warmest On Record For Both Hemispheres, For Land And Sea Temps
EDIT
The World Meteorological Organization says the planet experienced unprecedented high-impact climate extremes in the ten years from 2001 to 2010, the warmest decade since the start of modern measurements in 1850. Those ten years also continued an extended period of accelerating global warming, with more national temperature records reported broken than in any previous decade. Sea levels rose about twice as fast as the trend in the last century.
A WMO report, The Global Climate 2001-2010, A Decade of Climate Extremes, analyses global and regional temperatures and precipitation, and extreme weather such as the heat waves in Europe and Russia, Hurricane Katrina in the US, tropical cyclone Nargis in Myanmar, droughts in the Amazon basin, Australia and East Africa, and floods in Pakistan.
It says the decade was the warmest for both hemispheres, and for both land and ocean surface temperatures. There was a rapid decline in Arctic sea ice and accelerating loss of net mass from the Greenland and Antarctic ice sheets and from the worlds glaciers.
This melting and the thermal expansion of sea water caused global mean sea levels to rise about three millimetres annually, about double the observed 20th century trend of 1.6 mm per year. Global sea level averaged over the decade was about 20 cm higher than in 1880, the report says.
