Antarctic ice sheet
Some scientists have proposed that this region may be a "weak underbelly" of the West Antarctic Ice Sheet. The Pine Island and Thwaites Glaciers, which both flow into the Amundsen Sea, are two of Antarctica's largest five. Scientists have found that the flow of these glaciers has increased starting in the mid-2000s decade; if they were to melt completely global sea levels would rise by about 0.9–1.9 m (1–2 yards). Scientist have suggested that the loss of these glaciers would destabilise the entire West Antarctic ice sheet and possibly sections of the East Antarctic Ice Sheet.
