A study released this week added new fears to the fate of an important glacier in Antarctica and its impact on sea-level rise.
The Thwaites Glacier on the vast West Antarctica Ice Sheet is commonly called the "Doomsday Glacier" because of its potential to significantly raise sea levels by as much as 10 feet globally, inundating low-lying coastal communities and displacing millions.
The instability of Thwaites has been known and studied for a long time as a key indicator of climate change, but a new study released this week in the Proceedings of the National Academy of Sciences points to new evidence that warm seawater is pumping under the base of Thwaites and eroding it much more quickly than previously believed.
