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 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 ...
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)).
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 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.

A glacier with a sustained negative balance loses equilibrium and retreats. A sustained positive balance is also out of equilibrium and will advance to reestablish equilibrium. Currently, nearly all glaciers have a negative mass balance and are retreating. [13] Glacier retreat results in the loss of the low-elevation region of the glacier.
"The Thwaites is pretty much doomed." The findings are the culmination of six years of research conducted by the International Thwaites Glacier Collaboration, a collective of more than 100 scientists.
Frozen Planet II accompanies the TV series and was released in hardcover format on 11 September 2022 to coincide with the series debut in the UK. It is written by the series producers Mark Brownlow and Elizabeth White. The UK version is published by BBC Books. [24]
