is being lost at an average rate of 35,000 square kilometres a year since 1979, according to This is despite a rise in Antarctic sea ice.

Her analysis of global sea ice from November 1978 to December 2013 shows that the trend in ice extents was downward in all months of the year. The study has been published in the JournalofClimate.
