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 ...
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.
Human influence is the principal driver of changes to the cryosphere, of which glaciers are a part. [3] The glacier mass balance is the key determinant of the health of a glacier. If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice the ablation zone lost due to melting, a glacier will advance. If ...
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 ...
Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier.” Their findings give an alarming insight into future melting The ‘Doomsday Glacier’ is ...
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 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 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.
