2010 may become hottest year on record

AFTER eight months, 2010 is running neck-and-neck with 1998 for the hottest year at that point.

The planet's average temperature for January-August was 14.7 degrees Celsius, tying the record heat set for that period in 1998, the US National Oceanic and Atmospheric Administration said on Wednesday.

While 1998 was the hottest through the first eight months, 2005 is the hottest on record for the full year.

NOAA's National Climatic Data Center also reported it was the third hottest August on record with an average temperature of 16.2 degrees. The hottest August was 1998, followed by 2009.

Meanwhile, a separate report from the National Snow and Ice Data Center said Arctic sea ice cover appears to have reached its minimum extent for the year and is the third lowest extent recorded since satellites began measuring minimum sea ice extent in 1979.

Arctic sea ice covered an average of 6 million square kilometers during August. This is 22 percent below the 1979-2000 average extent and the 14th consecutive August with below-average Arctic sea ice extent, NOAA reported.

Melting sea ice is part of a pattern of changes atmospheric scientists attribute to global warming, which has been documented in rising temperatures over the last several decades.

Other changes include melting ice in Greenland and Antarctica, which can lead to rising sea levels, a decline in glaciers and changes in weather patterns around the world.

The new climate report said it was the hottest August in China since 1961, but the coolest since 1993 in Britain.
