The widespread Antarctic Sea Ice In The Mysterious

according to satellite records showed during the last 30 years, Arctic sea ice has decreased. But the sea ice in Antarctica is mysteriously continues to escalate.

Atlanta Georgia Tech researchers, Jiping Liu said more snow covered the upper layers of the sea which is currently less salty, so not too crowded. This layer becomes more stable so as to prevent the temperature to warm.

However, because of the increased amount of greenhouse gases that warm the ocean off the coast of Antarctica, then the subsequent impact was heavy rainfall that melt snow and ice, says new research published in the journal Proceedings of the National Academy of Sciences.

The more ice that melts, the more sunlight is absorbed well in the dark sea that reflected back into the atmosphere. The impact of further warming and sea is more sea ice is melting at the surface.
The loss of sea ice could also impact on reducing the number of glaciers when the quantity of water continues to grow, said Liu.

Antarctic Ocean, including the earth's coldest regions of low density or high water. This causes the region as 'the dominant driving forces' three-quarters of the circulation patterns of marine life.
These findings coincide with previous predictions that the reduced sea-ice loss in Antarctica can cause other side of life, said Walt Meier of the National Show and Ice Data Center (NSIDC) in Boulder, Colorado.

Kevin Trenberth, senior scientist at the National Center for Atmospheric Research Boulder, Colorado said that the study also shows the influence of the hole in the ozone layer.
Clouds are very bright summer encouraged by the presence of atmospheric holes have acted as a shield from global warming, scientists said.

Recent studies indicate that these holes may be closed, following the expansion phase of chemical elements, called chlorofluorocarbons.
When the clouds reflecting the sun was disappearing, the temperature in the southern hemisphere can rise faster.
"Recovery of the ozone hole in the future was a major factor of growth is expected," said Treth.
