In Antarctica, the world’s most dangerous glaciers are tearing loose from their restraints

Artarctic glaciers pulling away from restraints
Two Antarctic glaciers that have long kept scientists awake at night are breaking free from the restraints that have hemmed them in, increasing the threat of large-scale sea level rise.

Located along the coast of the Amundsen Sea in West Antarctica, the enormous Pine Island and Thwaites glaciers already contribute around 5% of global sea level rise. The survival of Thwaites has been deemed so critical that the U.S. and U.K. have launched a targeted multimillion dollar research mission to the glacier, whose loss could trigger the broader collapse of the West Antarctic ice sheet, which contains enough ice to raise seas by about 10 feet.
