The Thwaites Ice Shelf has acted like a dam for the eastern portion of glacier, bracing it and allowing for a slow melt rate, in contrast to the undefended western portion. [4] [6] According to the American Geophysical Union in a 2021 study, the Thwaites Eastern Ice Shelf (TEIS) buttresses one-third of Thwaites glacier.
The Thwaites Ice Shelf, a floating ice shelf which braces and restrains the eastern portion of Thwaites Glacier, is likely to collapse within a decade from 2021. [ 5 ] [ 18 ] [ 19 ] [ 20 ] The glacier's outflow is likely to accelerate substantially after the shelf's disappearance; while the outflow currently accounts for 4% of global sea level ...
There is a concern that if Thwaites’ ice shelves collapse, it will leave towering cliffs of ice exposed to the ocean. These tall cliffs could easily become unstable and tumble into the ocean ...
Further, it had been shown in 2021 that the Thwaites Ice Shelf, which restrains the eastern portion of the Thwaites Glacier, could start to collapse within five years. [ 41 ] [ 51 ] [ 52 ] The glacier would start to see major losses "within decades" after the ice shelf's failure, and its annual contribution to sea level rise would increase from ...
New research on Antarctica's rapidly melting Thwaites Glacier is providing some of the clearest insights yet into how the ice shelf is thinning from below.
Researchers said the entire glacier holds enough water to raise sea levels by more than 2 feet.

Antarctica's Thwaites Glacier — a key source of sea-level rise — will melt much faster after losing an ice shelf that holds the glacier like a dam.
