    1. our latest science at the Potsdam Institute shows that the Greenland Ice Sheet is connected to the West Antarctic Ice Sheet over the ocean circulation of heat. And that the whole AMOC, the North Atlantic overturning of heat, is slowing down because of the release of cold fresh water from the Greenland Ice Sheet. And when that slows down it locks in more warm surface water, saline surface water, in the Southern Ocean. 00:13:55 Which can explain why Antarctica is melting more rapidly than predicted.
      • for: cascading tipping points, cascading tipping points - Greenland - AMOC - Antarctica

      • highlights

        • latest research at PIK shows that the two poles are connected via the AMOC current.
          • Greenland ice sheet melt releasing cold fresh water is slowing down the North Atlantic overturning of heat.
          • The slowdown is keeping more warm saline water in place in the Southern Ocean, accelerating melting of the Antarctic ice sheet.
