A massive, calved iceberg seen from a research aircraft, Antarctic Peninsula region. October 31, 2017
Scientists at Germany’s Potsdam Institute for Climate Impact Research suggested a last-ditch engineering project to blanket a West Antarctic ice sheet’s surface with 7,400 gigatonnes of artificial snow over 10 years to stop it from sliding into the ocean and trigger a sea level rise, submerging coastal cities. People found the idea as preposterous as building protective domes to cover our cities or moving people to another planet to escape the troubles here.
