what happens if the thwaites glacier melts

0

NASA said sea levels could rise by 2 additional feet if the glacier collapses, which studies predict could happen in 50 to 100 years. When glaciers melt, because that water is stored on land, the runoff significantly increases the amount of … The Thwaites Glacier also slows the melting of other glaciers, which could raise sea levels an additional 8 feet if they melted. The melting of floating ice as it makes contact with the ocean is a key reason why the glacier is coming unglued. But satellite monitoring indicates this glacier is melting at an accelerating rate. 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. 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. 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. Can we save it in time? Last year, an immense cavity was found under the glacier.. The Pine Island Glacier drainage basin occupies an area of 175,000 square km. Without the Thwaites … 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. But it’s receding by about half a mile per year. ( See what a 10 billion ton chunk of ice looks like in this video ). So what happens if Thwaites melts? As Antarctic ice melts and the glaciers slide toward the ocean, Thwaites has a central position that governs how the other glaciers behave. A massive one that poses such risk it's been branded the 'Doomsday Glacier". The Thwaites Glacier is...a glacier. “If Thwaites glacier melts, on its own, we will see a rise in sea level around our own coast,” said Vaughan. Put simply, it causes sea levels to rise. The melting of the glacier already accounts for about 4% of global sea level rise. Sea ice forms and melts strictly in the ocean whereas glaciers are formed on land. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of … 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. 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. Submarine to explore why Antarctic ice is melting so quickly December 28, 2019. What Would Happen If The Pine Island Glacier 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. The situation is so bad that it could happen even under present-day ice-melting rates. 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. 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. The Pine Island Glacier and the Thwaites Glacier are two of the five largest ice streams in Antarctica. The latest warning over Antarctica’s melting glaciers comes amid a record heatwave on the other side of the planet in the Arctic. What happens when it melts? 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. A massive research effort is under way to understand Antarctica's Thwaites glacier before it is too late. Icebergs are chunks of glacial ice that break off glaciers and fall into the ocean. Antarctic ice melt and climate change will contribute to rising sea levels around the globe over the next 150 years. From The Guardian. ... the same wind patterns led to a lot of surface melting," he said. Thwaites holds back a … Antarctica's doomsday glacier is melting. This will allow the glacier’s potential sea-level contribution to be more accurately predicted. If the glacier melts entirely, it could trigger a 10-foot rise in sea levels. 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. 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 … 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. Seawater that is a few degrees above freezing is melting the ice shelf from below. Read more. The Thwaites Glacier in Antarctica is the size of Britain. 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. 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 larger than England, Wales and Northern Ireland put together. 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. When that happens, the glaciers behind the ice shelves speed up, releasing more ice to the sea. ... sea level rise has roughly doubled since 1990 — and could worsen if the Thwaites Glacier were to melt. THWAITES GLACIER OFFSHORE RESEARCH. Immediately, we'd get about 2 feet of sea level rise. The post What Could Happen If Glaciers Continue to Melt appeared first on Reader's Digest. Pine Island Glacier and Thwaites Glaciers, for example, are losing about 100 billion tons of ice each year, and more in bad years.
