2010, Year of the Hottest Throughout History

Trigger factor is the loss of ice in the Arctic waters.
Meteorological year 2010, which ended on November 30 is the warmest year on record throughout the 130 years of NASA. In this year, NASA records, the average global temperature of both land or sea during the last 12 months that began in December 2009 reached 14.64 degrees Celsius.

The figure was 0.65 degrees Celsius warmer than the average global temperature between 1951 and 1980, the period commonly used by scientists as the basis for comparison.

Meteorological year 2010 also slightly warmer than the previous warmest year of 2005 the world where temperatures averaged 14.53 degrees Celsius.
In 2010, soil temperatures across the region is also the hottest. During December 2009 to November 2010, measuring devices record the average temperature reached 14.85 degrees Celsius. When combined with ocean temperatures are also above average, global temperature reached 14.65 degrees Celsius.

November is generally a cold period to a number of regions in Europe. However, according to data from the Goddard Institute for Space Studies in New York NASA last November was the warmest November compared to the period 1951 to 1980. The temperature rise reaching 0.96 degrees Celsius.

"The main triggering factor is the increase in Arctic temperatures, in November, temperatures in the northern polar region was 10 degrees Celsius above normal," said James Hansen, klimatolog NASA's Goddard Institute and Director, as quoted from testimony, December 12, 2010.

In that month, Hansen said, arctic sea ice does not exist. And generally, waters filled with chunks of ice.
"The waters that are not filled with ice absorbs more solar radiation than ice-covered waters that can reflect some radiation back into space," he said.

The increase in global average temperatures were also occurs despite the appearance of La Nina, a natural phenomenon in the Pacific Ocean that triggered a decrease in surface ocean temperatures and affect the average global temperature. (Adi)
