17 February 2018, Independent, Global sea ice hits record low for January as the annual polar melting period expanded. The world’s sea ice shrank to a record January low last month as the annual polar melting period expanded, experts say. The 5.04 million square miles of ice in the Arctic was 525,000 square miles below the 1981-to-2010 ice cover average, making it the lowest January total in satellite records, according to the US National Snow and Ice Data Center (NSIDC). Combined with low levels in the Antarctic, global sea ice amounted to a record low for any first month of the year, the organisation concluded. The news comes just days after researchers from the University of Colorado Boulder said the rate at which sea levels are rising was increasing every year, driven mostly by accelerated melting in Greenland and Antarctica. The NSIDC, a respected authority on the Earth’s frozen regions, which researches and analyses snow, glaciers and ice sheets among other features, said that ice in the Arctic Ocean hit “a new record low” at both the start and end of last month. In an online post, the group said: “January of 2018 began and ended with satellite-era record lows in Arctic sea ice extent, resulting in a new record low for the month. Combined with low ice extent in the Antarctic, global sea ice extent is also at a record low.” Read More here
