In 2024, research indicated that instead of a relatively narrow grounding line which separates the parts of the glacier exposed to water and those safely behind them, there is a wider grounding zone of 2–6 km (1.2–3.7 mi) which is regularly exposed to water. Some areas of the glacier are additionally exposed to meltwater flowing another 6 ...
The Thwaites Ice Shelf is one of the biggest ice shelves in West Antarctica, though it is highly unstable and disintegrating rapidly. [2] [3] Since the 1980s, the Thwaites Glacier, nicknamed the "Doomsday glacier", [4] has had a net loss of over 600 billion tons of ice, though pinning of the Thwaites Ice Shelf has served to slow the process.

Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
Scientists using ice-breaking ships and underwater robots have found the Thwaites Glacier in Antarctica is melting at an accelerating rate and could be on an irreversible path to collapse ...
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. Scientists take a peek below Antarctica ...
An Antarctic glacier the size of Florida is on the verge of collapse, scientists with the American Geophysical Union warned Monday, a nightmare scenario made worse by climate change that could ...
Its most vulnerable parts like Thwaites Glacier, which holds about 65 cm (25 + 1 ⁄ 2 in) of sea level rise equivalent, are believed to require "centuries" to collapse entirely. [53] Thwaites' ice loss over the next 30 years would likely be around 5 mm of sea level rise between 2018 and 2050, and between 14 and 42 mm over 100 years. [40]
As of early 2020s, there is still net mass gain over the EAIS (due to increased precipitation freezing on top of the ice sheet), yet the ice loss from the WAIS glaciers such as Thwaites and Pine Island Glacier is far greater. By 2100, net ice loss from Antarctica alone would add around 11 cm (5 in) to the global sea level rise.
