Professor Thwaites never actually visited the glacier. If both collapsed, global sea levels could rise by over a metre. Joughin et al. Without them, the entire West Antarctic Ice Sheet could be more likely to collapse, leading global sea levels to rise by over three metres. 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. Scientists have discovered three channels of warm water under Antarctica's Thwaites Glacier mixing underneath the ice, threatening the glacier's collapse. al (2014) Marine Ice Sheet Collapse Potentially Under Way for the Thwaites Glacier Basin, West Antarctica. A Thwaites glacier collapse unleashes billions of cubic tons of water across our planet. Snows fall on land and these compact into ice that then flows out to sea. 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. International Thwaites Glacier Collaboration (ITGC) 18. The cavity has an area two-thirds the size of Manhattan – and NASA researchers described the find as ‘disturbing’. 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 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. 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. Here's what you need to know. 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. ... Collapse of massive Antarctic glacier could raise sea levels by 50cm. media caption Timelapse satellite images of Thwaites Glacier melting Thwaites is a marine-terminating glacier. 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. Scientists have used hot water to drill between 300 and 700 metres through the ice to the ocean and sediment beneath. A runaway collapse of the Thwaites glacier would lead to a global sea level rise of at least two feet. Over the last three decades, the Thwaites glacier has lost about 600 billion tons of ice. Thwaites glacier in West Antarctica are enormous in size and often referred to as the most dangerous glacier on Earth. Inevitable collapse? Science, 344 (6185), 735-738. The West Antarctic Ice Sheet (WAIS) is particularly vulnerable to ocean warming-induced collapse. Thwaites Glacier was named after Fredrik T. Thwaites (1883–1961), a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison. EARTH'S most dangerous chunk of ice is probably the Thwaites Glacier in Antarctica – so at risk it's called the "Doomsday Glacier". At first, water gnaws at the ice shelf from below, causing it to weaken and thin. Environment ‘Doomsday glacier’ melting due to warm water channels, scientists say. That is one of the most important questions in the world today. 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. International Thwaites Glacier Collaboration (2018, April 30) UK and US join forces to understand how quickly a massive Antarctic glacier could collapse. Thwaites glacier, if and when it collapses, could create global power shifts. “That’s one reason Thwaites has been changing,” he says. 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. Pine Island and Thwaites glaciers already contribute 5 percent of sea-level rise. Thwaites Glacier. It’s the first time scientists have drilled through Thwaites Glacier. 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. 17. The Florida-sized Thwaites Glacier originates in Antarctica and extends into the Amundsen Sea. Thwaites Glacier is one of the world’s most unstable glaciers. It’s melting — fast. If it collapsed, global sea levels could rise as much as two feet. Thwaites Glacier itself is massive. Such scenarios have the potential to wreck global economies. Investigating Thwaites Glacier. 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. But is it really at risk of disappearing, and how much damage would it cause? Source: Read Full Article. A Doomsday glacier scenario displaces millions of people, pushing them all inland. 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..
