On this map, arrows mark warm water currents, which are the main factor in the projected demise of the Thwaites Glacier. [23] Between 1992 and 2017, Thwaites Glacier retreated at between 0.3 km (0.19 mi) and 0.8 km (0.50 mi) annually, depending on the sector, [42] and experienced a net loss of over 600 billion tons of ice as the result.

Several glaciers, notably the much-visited Fox and Franz Josef Glaciers on New Zealand's West Coast, have periodically advanced, especially during the 1990s, but the scale of these advances is small when compared to 20th-century retreat. Both are more than 2.5 km (1.6 mi) shorter than a century ago.
The Thwaites Glacier has been studied for years as an indicator of human-caused climate change. In one nightmare scenario, the glacier's melt fuels a 50-foot rise in sea level.
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]
Since 2018, a team of scientists forming the International Thwaites Glacier Collaboration, has been studying Thwaites — often dubbed the “Doomsday Glacier” — up close to better understand ...
Scientists are warning the Antarctic Ice Sheet, known formally as the Thwaites Glacier, will deteriorate "further and faster" and that sea level rise triggered by the melting could impact ...
Although the glacier is replenished through snowfall, and glaciers generally accumulate more snow than they lose, the Thwaites Glacier is losing around 50 billion tons more ice than it is ...
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.
