Antarctic sea ice hits record low

Fri 17 Feb 2017


Antarctic sea ice extent has shrunk to the lowest recorded-level in last four decades, scientists say.

According to data from the US National Snow and Ice Data Centre (NSIDC), sea ice in the frozen continent covered just 2.26 million square kilometres on Tuesday, dipping below the earlier 1997 record low.

The sea ice is likely to decrease further as it usually melts to its smallest for the year by February end in the summer of southern hemisphere, researchers said. Sea ice at both poles has been expected to decline as the Earth heats up due to man-made global warming.

The average extent of sea ice around the South Pole has tended to expand in recent years and hit a record high of around 20.16 million square km in September 2014.
