Without them, the entire West Antarctic Ice Sheet could be more likely to collapse, leading global sea levels to rise by over three metres. The Thwaites glacier is 74,000 square miles, roughly the size of the UK. Such scenarios have the potential to wreck global economies. The key to West Antarctica’s future is the Thwaites glacier. The West Antarctic Ice Sheet (WAIS) is particularly vulnerable to ocean warming-induced collapse. Investigating Thwaites Glacier. al (2014) Marine Ice Sheet Collapse Potentially Under Way for the Thwaites Glacier Basin, West Antarctica. Inevitable collapse? It’s the first time scientists have drilled through Thwaites Glacier. It’s melting — fast. And by itself, it contains enough ice to raise sea levels by about 2 feet. The Florida-sized glacier extends deep into the heart of the Antarctica ice sheet. But because the glacier lends structure and support to many surrounding glaciers, its collapse would likely accelerate the disintegration of neighboring Antarctic glaciers, causing additional sea level rise. International Thwaites Glacier Collaboration (ITGC) 18. Scientists have used hot water to drill between 300 and 700 metres through the ice to the ocean and sediment beneath. Thwaites Glacier), sometimes referred to as the Doomsday Glacier, is an unusually broad and vast Antarctic glacier flowing into the Pine Island Bay, part of the Amundsen Sea, east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land Its surface speeds exceed 2 kilometres per year (1.2 miles per year) near its grounding line. Source: Read Full Article. If both collapsed, global sea levels could rise by over a metre. Thwaites Glacier is melting fast, and scientists fear its collapse could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. Environment ‘Doomsday glacier’ melting due to warm water channels, scientists say. Over the last three decades, the Thwaites glacier has lost about 600 billion tons of ice. Antarctica, Co., glacier, Thwaites. EARTH'S most dangerous chunk of ice is probably the Thwaites Glacier in Antarctica – so at risk it's called the "Doomsday Glacier". While the papers came to similar conclusions regarding the hypothetical outcome of such a glacier collapse, they disagreed on exact timelines. “That’s one reason Thwaites has been changing,” he says. That is one of the most important questions in the world today. media caption Timelapse satellite images of Thwaites Glacier melting As the glacier continues to melt, and its grounding line shifts farther inland, scientists suspect Thwaites will eventually reach a point of no return -- with its collapse inevitable. Science, 344 (6185), 735-738. AN ENORMOUS lump of ice dubbed the "world's most dangerous glacier" is teetering on the verge of collapse, threatening to raise global sea levels by an unprecedented eight feet. Last February we posted “The Doomsday Glacier — the Thwaites Glacier Melting From Below,” about the flow of warmer water that is melting the massive West Antarctic glacier from below. Accessed February 5, 2020. 17. Scientists have discovered three channels of warm water under Antarctica's Thwaites Glacier mixing underneath the ice, threatening the glacier's collapse. The cavity has an area two-thirds the size of Manhattan – and NASA researchers described the find as ‘disturbing’. But is it really at risk of disappearing, and how much damage would it cause? The Florida-sized Thwaites Glacier originates in Antarctica and extends into the Amundsen Sea. A runaway collapse of the Thwaites glacier would lead to a global sea level rise of at least two feet. Thwaites glacier, if and when it collapses, could create global power shifts. Scientists say Thwaites and the other glaciers are not likely to collapse in the next century; they are simply too big to fail right now. If it collapsed, global sea levels could rise as much as two feet. The collapse of the Thwaites Glacier would cause an increase of global sea level of between one and two metres (three and six feet), with the potential for more than twice that from the entire West Antarctic Ice Sheet. ... Collapse of massive Antarctic glacier could raise sea levels by 50cm. Thwaites Glacier acts like a giant cork that holds back the West Antarctic Ice Sheet (NASA) A glacier described as the ‘world’s most dangerous’ is showing worrying signs of collapse, after scientists found an 1,000ft tall cavity growing beneath the ice.. Thwaites is a marine-terminating glacier. Glaciers like Thwaites that terminate in the ocean tend to follow a familiar pattern of collapse. Thwaites glacier is larger the England and could drive global sea levels up by two feet (60cm) if it were to totally collapse. Thwaites Glacier Video (Video Credit: Vox) O ur world is rapidly transforming. Joughin et al. Thwaites Glacier was named after Fredrik T. Thwaites (1883–1961), a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison. Thwaites Glacier is one of the world’s most unstable glaciers. A HUGE Antarctic glacier which could collapse within decades, causing a rapid rise in sea levels, will be the subject of a joint UK-US research project. Thwaites Glacier in West Antarctica covers 182,000 square km and is described as 'world's most dangerous' One recent study warned the 'doomsday' Antarctic glacier that could collapse within decades If Thwaites collapsed, it could raise global sea level by more than half a meter (nearly two feet) and lead to a domino effect of further glacier collapse in West Antarctica. Some scientists fear that with an increased rate of 50 billion tons of ice lost a year in recent times, runaway instability of the glacier may already be underway. Here's what you need to know. Professor Thwaites never actually visited the glacier. It could also be on the verge of a rapid collapse. Joughin, I. et. At first, water gnaws at the ice shelf from below, causing it to weaken and thin. A Thwaites glacier collapse unleashes billions of cubic tons of water across our planet. https://www.cnn.com/2020/09/09/weather/thwaites-glacier-antarctica-scli-intl Thwaites glacier in West Antarctica are enormous in size and often referred to as the most dangerous glacier on Earth. The Thwaites Glacier of West Antarctica is one of the largest WAIS regional contributors to sea level rise, and has been considered to be potentially unstable for many years. Total collapse of the glacier would raise global sea levels by 10 feet. Thwaites Glacier itself is massive. A Doomsday glacier scenario displaces millions of people, pushing them all inland. Pine Island and Thwaites glaciers already contribute 5 percent of sea-level rise. Thwaites Glacier. Thwaites Glacier and Pine Island Glacier are two of the biggest and fastest-retreating in Antarctica. The paper notes that Thwaites glacier covers 74,000 sq miles (192,000 sq km), … International Thwaites Glacier Collaboration (2018, April 30) UK and US join forces to understand how quickly a massive Antarctic glacier could collapse. Currently, Thwaites' ice loss contributes approximately 4% to the annual rise in global sea-levels, with the potential to add 65cm in total should the whole glacier collapse.
