        "Models suggest that the Greenland Ice Sheet could be doomed at 1.5 degrees C [2.7 degrees F] of warming, which could happen as soon as 2030. Exceeding the 3 ice sheet tipping points could cause an irreversible rise in sea levels of ~13 meters (43 feet)."https://e360.yale.edu/features/as-climate-changes-worsens-a-cascade-of-tipping-points-looms …
