NOAA: 2010 warmest on Record

16.01.2011, Age: 2711 days

Another record breaking warm year, 2010 shares with 2005 the title of the warmest year after a steady rise from the average post-1880 temperature starting in 1976.

Last year was also the wettest. Although precipitation varies from place to place, many areas, like Australia, southern and southeastern Asia, Central America and central Europe suffer from major, sometimes catastrophic floods.

NOAA: Global Highlights

For 2010, the combined global land and ocean surface temperature tied with 2005 as the warmest such period on record, at 0.62°C (1.12°F) above the 20th century average of 13.9°C (57.0°F). 1998 is the third warmest year-to-date on record, at 0.60°C (1.08°F) above the 20th century average.

The 2010 Northern Hemisphere combined global land and ocean surface temperature was the warmest year on record, at 0.73°C (1.31°F) above the 20th century average. The 2010 Southern Hemisphere combined global land and ocean surface temperature was the sixth warmest year on record, at 0.51°C (0.92°F) above the 20th century average.
The global land surface temperature for 2010 tied with 2005 as the second warmest on record, at 0.96°C (1.73°F) above the 20th century average. The warmest such period on record occurred in 2007, at 0.99°C (1.78°F) above the 20th century average.
The global ocean surface temperature for 2010 tied with 2005 as the third warmest on record, at 0.49°C (0.88°F) above the 20th century average.
In 2010 there was a dramatic shift in the El Niño–Southern Oscillation, which influences temperature and precipitation patterns around the world. A moderate-to-strong El Niño at the beginning of the year transitioned to La Niña conditions by July. At the end of November, La Niña was moderate-to-strong.
