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]
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.

Scientists using ice-breaking ships and underwater robots have found the Thwaites Glacier is melting at an accelerating rate and could be on an irreversible path to collapse.
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.
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 ...
EIS imagery has appeared in time-lapse videos displayed in the terminal at Denver International Airport; in media productions such as the 2009 NOVA Extreme Ice documentary on PBS; [1] and is the focus of the feature-length film Chasing Ice, directed by Jeff Orlowski, [2] which premiered at the Sundance film festival in Utah on January 23, 2012. [3]
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 ...
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.
