In 2001, an analysis of radar interferometry data from the Earth Remote Sensing Satellites 1 and 2 by Eric Rignot revealed that the grounding line of Thwaites Glacier had retreated by 1.4 km (0.87 mi) between 1992 and 1996, while its strongly negative mass balance (annual loss of around 16 billion tonnes of ice, equivalent to 17 cubic ...
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. [5]
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 new findings from the International Thwaites Glacier Collaboration add to a vast body of research on how the deterioration of glaciers worldwide could contribute to sea level rise.
Larter is one of 100 members of the International Thwaites Glacier Collaboration (ITGC), a group that monitors and probes the ice. The ITGC gathered in England this week for its final meeting.
Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
Researchers said the entire glacier holds enough water to raise sea levels by more than 2 feet. "Doomsday glacier" ice shelf could shatter within 5 years, scientists say Skip to main content
