THWAITES GLACIER OFFSHORE RESEARCH. Thwaites has been described as one of the world's most dangerous glaciers because its demise could lead to rapid changes in global sea levels. Antarctica's doomsday glacier is melting. ... sea level rise has roughly doubled since 1990 — and could worsen if the Thwaites Glacier were to melt. Over the past 30 years, ice loss from Thwaites and its neighbouring glaciers has increased more than fivefold, accounting for more than 4% of global sea-level rise. NASA said sea levels could rise by 2 additional feet if the glacier collapses, which studies predict could happen in 50 to 100 years. Warm water has recently been recorded near the Thwaites Glacier grounding line—the location where the glacial ice rests on the seafloor. The Thwaites Glacier is...a glacier. Thwaites is the most worrying glacier in Antarctica because of its size — it is unusually wide, presenting a 75-mile front of ice to the ocean, without any rocks or mountains to hem it in. The Pine Island Glacier drainage basin occupies an area of 175,000 square km. Seawater that is a few degrees above freezing is melting the ice shelf from below. The study comes on the heels of research published last week that found deep channels under the Thwaites Glacier may be allowing warm ocean water to melt the underside of its ice. ( See what a 10 billion ton chunk of ice looks like in this video ). Scientists’ ultimate goal is to develop more accurate global sea level rise models so coastal residents and governments have enough time to plan for future changes. As Antarctic ice melts and the glaciers slide toward the ocean, Thwaites has a central position that governs how the other glaciers behave. Antarctic ice melt and climate change will contribute to rising sea levels around the globe over the next 150 years. This will allow the glacier’s potential sea-level contribution to be more accurately predicted. It’s the latest bad sign for the Thwaites Glacier, which has recorded some of the most rapid melt rates out of anywhere in Antarctica. The expedition to Thwaites is part of the race to discover how fast the massive glacier is melting and what that will mean for global sea level rise over the next century. If the glacier melts entirely, it could trigger a 10-foot rise in sea levels. The latest warning over Antarctica’s melting glaciers comes amid a record heatwave on the other side of the planet in the Arctic. A massive research effort is under way to understand Antarctica's Thwaites glacier before it is too late. Submarine to explore why Antarctic ice is melting so quickly December 28, 2019. Can we save it in time? From the Guardian: An international team of scientists has reached the Thwaites glacier in Antarctica and is preparing to drill through more than half a kilometre of ice into the dark waters beneath. When that happens, the glaciers behind the ice shelves speed up, releasing more ice to the sea. The situation is so bad that it could happen even under present-day ice-melting rates. If all glacial ice were to melt, it would cause the sea level to rise 230 feet around the world. A team of UK and US researchers have found a series of deep channels beneath Thwaites Glacier thought to be acting as pathways for warm ocean water to melt the underside of the ice. When glaciers melt, because that water is stored on land, the runoff significantly increases the amount of … The Pine Island Glacier and the Thwaites Glacier are two of the five largest ice streams in Antarctica. But it’s receding by about half a mile per year. Thwaites Glacier's melting is nearing a 'tipping point' and could trigger an unstoppable 20-inch rise in global sea levels, warns new research Thwaites Glacier in … Immediately, we'd get about 2 feet of sea level rise. The Thwaites glacier is larger than England, Wales and Northern Ireland put together. But satellite monitoring indicates this glacier is melting at an accelerating rate. The melting of the glacier already accounts for about 4% of global sea level rise. What happens when it melts? Thwaites Glacier, also known as the "doomsday glacier", is reported to be melting quicker than previously thought - scientists are now trying to find out why. What Would Happen If The Pine Island Glacier Melts? The Thwaites Glacier also slows the melting of other glaciers, which could raise sea levels an additional 8 feet if they melted. Last year, an immense cavity was found under the glacier.. Sea ice forms and melts strictly in the ocean whereas glaciers are formed on land. But the real danger is what happens after. If Thwaites melts away, that much-larger ice block will add water to our oceans as well, further driving up sea level rise. Without the Thwaites … Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of … From The Guardian. Read more. Put simply, it causes sea levels to rise. “If Thwaites glacier melts, on its own, we will see a rise in sea level around our own coast,” said Vaughan. Pine Island Glacier and Thwaites Glaciers, for example, are losing about 100 billion tons of ice each year, and more in bad years. Icebergs are chunks of glacial ice that break off glaciers and fall into the ocean. 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. Behind the glacier lies an even larger body of ice that, for as long as Thwaites is intact, is protected from contact with too-warm waters. So what happens if Thwaites melts? Melting at Thwaites grounding zone and its control on sea level (MELT) MELT is an ice-based project to understand how warm waters are affecting the Thwaites Glacier at the grounding line – the point where the glacier goes afloat to become ice shelf. A massive one that poses such risk it's been branded the 'Doomsday Glacier". The melting of floating ice as it makes contact with the ocean is a key reason why the glacier is coming unglued.
