Retreating glacier the size of Florida

  • A glacier in Antarctica that could raise sea levels several feet is disintegrating faster than last predicted, according to a new study published Monday in the journal Nature Geoscience.


    The Thwaites Glacier — dubbed the “doomsday glacier” because scientists estimate that without it and its supporting ice shelves, sea levels could rise more than 3 to 10 feet — lies in the western part of the continent. After recently mapping it in high-resolution, a group of international researchers found that the glacial expanse experienced a phase of “rapid retreat” sometime in the past two centuries — over a duration of less than six months.


    According to a news release accompanying the study, researchers concluded that the glacier had “lost contact with a seabed ridge” and is now retreating at a speed of 1.3 miles per year — a rate double what they predicted between 2011 and 2019….


    According to the United Nations, more than 40 percent of the world’s human population lives within 60 miles of the coast — areas that will be hit hard by rising tides.
