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 ...
The edge of the Thwaites Glacier extends into the Amundsen Sea in western Antarctica. NASAThis episode of The Conversation Weekly podcast is about the Thwaites Glacier in Antarctica.
Thwaites Glacier is an unusually broad and vast Antarctic glacier located east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land.It was initially sighted by polar researchers in 1940, mapped in 1959–1966 and officially named in 1967, after the late American glaciologist Fredrik T. Thwaites.
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.

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 ...
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]
The outlook for "Doomsday Glacier" just got gloomier. Scientists are warning the Antarctic Ice Sheet, known formally as the Thwaites Glacier, will deteriorate "further and faster" and that sea ...
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, inundating low-lying coastal ...
