    1. Der grönländische Eisschild verliert aufgrund der globalen Erhitzung 30 Millionen Tonnen Eis pro Stunde und damit 20% mehr als bisher angenommen. Manche Forschende fürchten, dass damit das Risiko eines Kollaps des Amoc größer ist als bisher angenommen. Der Eisverlust ist außerdem relevant für die Berechnung des Energie-Ungleichgewichts der Erde durch Treibhausgas-Emissionen. https://www.theguardian.com/environment/2024/jan/17/greenland-losing-30m-tonnes-of-ice-an-hour-study-reveals

    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.

    1. In Grönland tritt die Mehrheit der Bevölkerung für die Unabhängigkeit von Dänemark ein. Man sieht Chancen, den Bergbau zu entwickeln, da Grönland über viele Bodenschätze verfügt, die für erneuerbare Energien wichtig sind. Wichtig für das Land ist auch das Abschmelzen des Nordpolareises, durch das neueSschifffahrtsrouten möglich werden. Dänemark fördert die Unabhängigkeit bisher nicht.

    1. In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight. Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change.

      A great example of the lag that large, complex systems exhibit when responding to significant input changes.

      Lag is something that humans are woefully weak at recognizing and understanding. This, and other systems concepts are what we need to add to the curriculum at all levels of education, to change this very significant shortcoming of "common knowledge".
