Thwaites Glacier in Antarctica is 74,000 square miles, the size of Great Britain, and is thought to be particularly susceptible to climate change. It is massive - roughly the size of Britain. Climate change: what Antarctica’s ‘doomsday glacier’ means for the planet . The Thwaites Glacier is the largest, most menacing source of rising sea levels all over the world, and it is melting at an alarming rate. It's swiftly melting, and a collapse could cause a dramatic increase in sea level rise. The findings are part of the International Thwaites Glacier Collaboration — a UK and U.S.-led research expedition. Even now, ice draining from Thwaites into the Amundsen Sea accounts for about 4% of global sea-level rise. Jeremy Harbeck. The glacier earned its ominous "doomsday" nickname because it's one of Antarctica's fastest melting glaciers. Even now, ice draining from Thwaites Glacier into the Amundsen Sea accounts for about 4% of global sea-level rise … Already, ice draining from Thwaites accounts for about 4 percent of global sea-level rise. Greenland's largest glaciers could lose even more ice than previously predicted -- a development that could have huge consequences for the rate of global sea level rise… When it does, it will raise sea levels by about 1.6-2 feet. Three feet of sea-level rise would be bad, leading to more frequent flooding of U.S. cities such as New Orleans, Houston, New York, and Miami. The Jakobshavn Glacier, only a few miles wide, has not significantly changed the rate of global sea-level rise. It already accounts for 4% of world sea level rise each year - a huge figure for a single glacier - and satellite data show that it is melting increasingly rapidly. Glaciologists have described Thwaites as the "most important" glacier in the world, the "riskiest" glacier, even the "doomsday" glacier. Melting ice from the Thwaites into the Amundsen Sea already accounts for approximately 4% of current global sea-level rise — a number that would significantly increase when the glacier … A massive research effort is under way to understand Antarctica's Thwaites glacier before it is too late. Even by the standards of Antarctica, there are few places as remote and hostile as Thwaites Glacier. It would be nearly impossible to predict how much sea levels will rise down to the exact inch, day, or year. Scientists have issued new warnings over a glacier in Antarctica that is described as “the doomsday glacier” because its collapse could lead to rapid sea-level rise.. Pine Island Glacier shelf edge. Thwaites Glacier is melting at an alarming rate, triggering fears over rising sea levels . Thwaites glacier, which is roughly the size of Great Britain, accounts for 4 per cent of world sea level rise each year, and is melting at an accelerating rate. Notice the size of the glacier’s main ice tongue in 2001, when the glacier was advancing by about 4 kilometers per year. Scientists have made a surprising discovery of warm water under a huge glacier which is the cause behind its gradual depletion. About the size of Florida, Thwaites Glacier is currently responsible for approximately 4 percent of global sea level rise. Jasper Hamill Wednesday 29 Jan 2020 9:52 am. Thwaites -- which is as big as the United Kingdom -- is also referred to as the ‘Doomsday Glacier’ because if it ever collapsed, global sea levels would rise by more than half a metre on its own. Indeed, Thwaites Glacier is one of the largest contributors to global sea level rise from the West Antarctic Ice Sheet. But researchers are keeping close tabs on what's happening to the glacier, which will give them a much better shot at providing specific indications about where the situation is headed. Scientists drill into Antarctic ‘doomsday glacier’ to see if it will collapse and flood the world . 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. This could cause a domino effect causing other ice bodies to join in, raising the water levels by a whopping 2-3 metres, while causing catastrophic damage to coastal areas around the world. The 'doomsday' glacier. 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. Around 80 billion tonnes of ice from the glacier is currently draining out into the Amundsen Sea each year – accounting for around four per cent of the planet’s annual sea-level rise. Thwaites Glacier is melting at an alarming rate, triggering fears over rising sea levels. But the sea-level rise wouldn't stop there. The glacier has been dubbed the “doomsday glacier” due to its enormous size — as large as the state of Florida — and its ability to raise sea levels by over 25 inches alone if it were to suffer rapid collapse. Scientists have discovered record warm water beneath Antarctica's "doomsday glacier" for the first time, leading to concerns for the glacier whose collapse could contribute nearly a meter to global sea level rise. Thwaites Glacier in western Antarctica is in serious danger. Scientists drill into Antarctica's 'doomsday' Thwaites glacier for the first time in a bid to stop dramatic sea level rise as the ice shelf the size of BRITAIN melts at an alarming rate Scientists estimate the glacier will lose all of its ice in about 200 to 600 years. It already accounts for 4 percent of world sea level rise each year - a huge figure for a single glacier - and satellite data show that it is melting increasingly rapidly.
