For a third time in a row, Antarctic sea ice has reached record proportions. The Southern Hemisphere seas are showing record breaking ice growth but scientists are worried by the effects of global warming on the melting Arctic sea.
According to the National Snow and Ice Data Center (NSIDC), it is for the third year in a row that the southern hemisphere sea ice has reached record levels. The sea ice in the Arctic is shrinking at an alarming pace. The NSIDC has said that this could be a factor for the rise in sea ice levels around the Antarctic.
The Southern Hemisphere warms more slowly in comparison to the Northern Hemisphere. The melting from the mainland and the subsequent insistent freezing winds could also cause the record rise in sea level ice.
According to the NSIDC, the peak winter ice levels in the Antarctica have been growing at a rate of 1.5 percent per decade, since 1979. The frosty air froze ocean water into 7.6 million square miles or 19.7 million square kilometers of the Antarctic sea ice. This could break the previous year records since several weeks of winter are still remaining.
Jan Leiser, of the Antarctic Climate and Ecosystems Cooperative Research Centre in Hobart says, “The raise in Antarctic sea ice level may seem contradictory set modifications in the universal climate, although it’s not as we think about several other causes at play.”
The situation is just opposite in the Arctics. The Arctic ice cap was 1.96 million square miles or 5.07 million square kilometers on Sept. 15. Last year the figure was 1.97 million square miles or 5.1 million square kilometers. It was the sixth-lowest level on record since satellite tracking began in 1979.
Axel Schweiger, chairman of the University of Washington’s Polar Science Center in Seattle says, “In the short term, it seems like there hasn’t been much ice loss in the past couple of years, but I think it’s still very much within the long-term trend of declining sea ice. One shouldn’t necessarily expect every year to be a record low.”
