The Thwaites Glacier, an ice formation the size of Florida, can change the world. And the latest research shows that some of its most vulnerable spots are in greater danger than previously thought ...
Scientists have long known Florida-sized Thwaites was vulnerable, in part because of its geography. The land on which it sits slopes downwards, meaning as it melts, more ice is exposed to ...
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 ...
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.

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.

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 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 ...
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 ...
