[26][27], At the beginning of 2020, researchers from the ITGC took measurements to develop scenarios for the future of the glacier and to predict the time frame for a possible collapse: The erosion of the glacier by warmed ocean water seems to be stronger than expected. Thwaites Glacier is closely watched for its potential to raise sea levels. The researchers, working on the Thwaites Glacier, recorded water temperatures at the base of the ice of more than 2 degrees Celsius, or 3.6 degrees Fahrenheit, above … [15], A 2014 University of Washington study, using satellite measurements and computer models, predicted that the Thwaites Glacier will gradually melt, leading to an irreversible collapse over the next 200 to 1000 years.[16][17][18][19][20][21]. The paper notes that Thwaites glacier covers 74,000 sq miles (192,000 sq km), and is particularly susceptible to climate change. [12] The discovery was a part of the International Thwaites Glacier Collaboration, a US-UK-based research firm. About the size of Florida, Thwaites Glacier is currently responsible for approximately 4 percent of global sea level rise. “The more this marine ice sheet instability occurs, the wider the range of possible future sea level rise becomes,” Robel says. All these observational projects will provide input to the two modeling studies, PROPHET and DOMINOS, which will strive to create a better forecast of the glacier’s retreat, and explore conditions that could lead to a rapid increase in ice loss. [14], Swamp-like canal areas and streams underlie the glacier. Antarctica’s Thwaites Glacier has been in the spotlight in recent years, as scientists have undertaken a multi-part international project to study the vast glacier from all angles. [2] Its surface speeds exceed 2 kilometres per year (1.2 miles per year) near its grounding line. Cavity roughly two-thirds the size of Manhattan is growing under Thwaites, described by scientists as world's most dangerous glacier, per a NASA study. (NASA) "I think this is a big step towards helping understand that," he added. [9] In 2017, scientists discovered previously unknown volcanoes nearby. [6] Along with the Pine Island Glacier, it has been described as part of the "weak underbelly" of the West Antarctic Ice Sheet, due to its apparent vulnerability to significant retreat. This iceberg was about 85 km long by 65 km wide, with a total area of some 5,490 km². This study has raised alarm regarding the glacier collapse, which can lead to nearly 3 ft (0.9 m) rise in the sea level. [13], Extensive calving at the marine terminus of Thwaites Glacier is monitored by remote sensing and seismological observations, with the largest events being seismically detectable at ranges up to 1600 km. There are far more massive glaciers, like the Thwaites Glacier, which is about the size of Florida.

It was named by the Advisory Committee on Antarctic Names[3] in 1967 after Fredrik T. Thwaites (1883–1961), a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison. [8] Since the 1980s, the glacier had a net loss of over 600 billion tons of ice though 2017.
