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 ...
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 ...
At 120 km (75 mi) in width, [2] Thwaites Glacier is the single widest glacier in the world, and it has an area of 192,000 km 2 (74,000 sq mi). This makes it larger than the American state of Florida (170,000 km 2 (66,000 sq mi)), and a little smaller than the entire island of Great Britain (209,000 square kilometres (81,000 square miles)).
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]
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.

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.
Some types of climate engineering are highly controversial due to the large uncertainties around effectiveness, side effects and unforeseen consequences. [7] Interventions at large scale run a greater risk of unintended disruptions of natural systems, resulting in a dilemma that such disruptions might be more damaging than the climate damage ...
