Britain-sized Antarctic Glacier Threatens Global Coasts
Antarctica’s Thwaites Glacier, nearly the size of Britain, could collapse sooner than expected, potentially adding about three metres to global sea levels and flooding coastlines worldwide. The glacier’s last ice shelf is poised to disintegrate as subsurface warming weakens the ice, putting the Netherlands, Bangladesh, the Maldives and other island nations at high risk. In the United States, major coastal cities like Miami, New York and New Orleans could face significant inundation, with projections that up to 60% of Miami-Dade County could be underwater.
