The sea ice around the Antarctic and Arctic regions are at low record and scientists observed low ice levels around the poles. This is an indication of climate change effects and so Arctic is worrisome say scientists. Experts are shocked by the decrease in the Antarctic sea ice.
In the Arctic, as of Nov. 20, sea ice extent was 8.625 million square kilometers, which measures that the ocean areas are covered by 15 percent sea ice.
The ice is melting fast at Arctic and the warmth of modern life has resulted in this risk. Normally, in the Arctic, the wintry conditions make the sea ice increase, but in the past several days, the sea ice has come to a halt owing to above normal temperatures. It is warmer than usual that the winds from south are bringing warmer air in that region.
A climatologist, Claire Parkinson, at NASA’s Goddard Space Flight Center, said the above-average temperatures are concerning, but are not surprising entirely. She said, the Arctic is decreasing for many years.
Melting sea ice does not raise sea levels, melting land ice causes that. The melting sea ice results in warmer temperatures and contributes indirectly to sea level rise threatening coastal communities enveloping the planet.
The sea ice as of Nov. 20, in the Antarctic covered 13.616 million square kilometers. The sea ice extent is shrinking as summer starts to set in. But this year, the sea ice coverage drop is more dramatic.
The sea ice extent had actually risen in the Antarctic hitting record highs in 2014. Thus a climate change is the cause of worry. Though recently sea ice extent shows increase, scientists believe climate change is affecting Antarctic.
