Antarctica has set a new sea ice record, which is odd considering the global temperature is rising, though scientists said global warming is likely the reason for the increase. The National Snow and Ice Data Center (NSICD) said this week the sea ice extent already hit the record for the third straight year with a few weeks to spare.
Jan Lieser of the Antarctic Climate and Ecosystems Cooperative Research Centre in Hobart, said that the increase will not sustain itself. “By 2100 we will see dramatic reductions,” she said, according to the publication. “Once it goes belly-up it’s not good for the rest of the world.”
“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,” Axel Schweiger, chairman of the University of Washington’s Polar Science Center in Seattle, told LiveScience. “One shouldn’t necessarily expect every year to be a record low.
This the first time that the sea ice level could exceed 7.7 million square miles in historical records, according to the data collected from satellite readings by Phil Reid of the Centre for Australian Climate and Weather Research.
“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”, says Jan Leiser, of the Antarctic Climate and Ecosystems Cooperative Research Centre in Hobart.
According to scientists cited by LiveScience, global warming is the cause of both the Arctic’s sea ice decrease and Antarctica’s sea ice increase. Scientists report that Antarctica’s sea increase may be the consequence of more powerful winds. These winds, according to studies cited by LiveScience, are more powerful because the southern polar vortex is agitating the air closer to Antarctica as a result of the ozone hole and greenhouse gases.
