So the western sheet is at risk of flooding (and therefore melting) if the barrier of ice is damaged significantly. “Doomsday” Glacier . Around 90% of the world's freshwater is in Antarctica, so the potential for melt is huge. Thwaites and its neighbor, the Pine Island Glacier, are among those in West Antarctica most influenced by the climate crisis. It's mostly above sea level, and the ice is very thick. “Because it’s uncertain, Thwaites has the potential to really be the Doomsday Glacier. When exposed ice sits lower than the water, there’s no stopping the melt, Schmidt says. To make matters worse, Nasa uncovered an enormous cavity below Thwaites just last year. from Jemma Cox Plus . In other news, the first full map of the hidden continent below Antarctica has been revealed. A higher percentage of the sheet is then in contact with water. It's been described as the "Doomsday" glacier … Your email address is used to log in and will not be shared or sold. But is it really at risk of disappearing,… Thwaites also slopes downwards towards the ocean, which means the higher ice at the back is constantly trying to force itself into the sea. Some call it the Doomsday Glacier. Read our privacy policy. The Sun website is regulated by the Independent Press Standards Organisation (IPSO), Our journalists strive for accuracy but on occasion we make mistakes. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. Shutterstock. In other words, if Thwaites glacier melts, two feet is immediately added to the ocean’s sea levels. The Doomsday Glacier In the farthest reaches of Antarctica, a nightmare scenario of crumbling ice – and rapidly rising seas – could spell disaster for a warming planet. Rising sea levels pose real risks to many people around the world. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of water. A look at maps of the region’s ice loss makes this clear, says Nick Holschuh, a […] Thwaites glacier is larger the England and could drive global sea levels up by two feet (60cm) if it were to totally collapse. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. Environment Why Scientists Are So Worried About Antarctica's Doomsday Glacier Thwaites Glacier in western Antarctica is in serious danger. "The Sun", "Sun", "Sun Online" are registered trademarks or trade names of News Group Newspapers Limited. “The water will flow in, the ice will thin rapidly, and then the whole thing that's been stable and sitting on a continent for thousands of years will go away.”. Now, scientists … This is ironically true, as the fake climate scare of the Doomsday Glacier is really a doomsday for climate alarmism. The Doomsday Glacier In the farthest reaches of Antarctica, a nightmare scenario of crumbling ice – and rapidly rising seas – could spell disaster for a warming planet. Beach shorelines would be three feet shallower than they are now — and storm surges during severe weather events would reach farther and deeper inland than ever before. It could melt away in a few decades. It sits on land below sea level. What we do know is that as seas warm and rise, Thwaites will be under increasing threat. And without the physical support of the massive glacier, chunks can start to break off more easily. https://www.yahoo.com/news/antarctic-doomsday-glacier-161305996.html “We do know that Thwaites Glacier is quite important,” says Atsuhiro Muto, a polar geophysicist at Temple University. And let's not forget: rising sea levels are also a self-fulfilling property. 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. The real threat is all of the Antarctic ice locked on land, which can melt and flow into the ocean. May 9, 2017. Sometimes called the Doomsday Glacier due to the potential impact its collapse could have on sea levels, Thwaites is unusually broad and fast. Officially called the Thwaites Glacier, this mass of ice nestled into the western edge of Antarctica is melting at an alarming rate. Article/Op-Ed in Rolling Stone. A look at maps of the region’s ice loss makes this clear, says Nick Holschuh, a geologist at Amherst College. Officially called the Thwaites Glacier, this mass of ice nestled into the western edge of Antarctica is melting at an alarming rate. It’s sometimes called the Doomsday glacier — because its retreating faster all the time and calving larger and larger icebergs. And it's melting very quickly, which is a huge concern to scientists. Also dubbed the “doomsday glacier,” this chunk of ice gets its nickname because it is one of the frozen desert’sfastest melting areas. It also has the potential to not be so bad,” Muto says. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. It is massive - roughly the size of Britain. If completely liquified, Thwaites would raise sea levels by 1.5 to 3 feet. Which makes me optimistic that we're going to learn a lot.”, Earth Is on the Cusp of the Sixth Mass Extinction. “But still, how much and how fast that is going to increase into the decades and centuries is still uncertain.”. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. 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. And when it does collapse, it could trigger the collapse of the West Antarctic ice sheet also. The glacier holds two feet of sea level but more importantly, it is the "backstop" for four other glaciers which holds an additional 10 to 13 feet of sea level rise. It's swiftly melting, and a collapse could cause a dramatic increase in sea level rise. Want it all? It's a little smaller than Britain, so it's absolutely massive. To behave accordingly — like put up sea walls or move out of low-lying areas — policymakers need to know how much and how fast the waterline will encroach. Sea levels rising creates an obvious risk to any low-lying populated regions near the coast. And, experts think melting Antarctic ice could cause areas of the ocean to turn a "deep green" colour by 2100. This cyclical process concerns scientists, who fear a "runaway effect" where sea levels begin to rise very quickly. Get unlimited access when you subscribe. 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. This video on the doomsday glacier explains why. It's melting quickly, and could very well disappear within a few centuries. Its fastest flowing grounded ice is centred between 50 and 100 kilometres east of … Read more at Climate Realism. Your website access code is located in the upper right corner of the Table of Contents page of your digital edition. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. So long as Thwaites connects with the earth beneath it, the glacier will block warm waters from creeping up to the broader, thicker ice — the Western Antarctic Ice Sheet — sitting behind it. Antarctica's Thwaites Glacier has been called the "Doomsday Glacier." Some go so far as to term it the Doomsday glacier. “It has really allowed us to look at this system in a totally new way. EARTH'S most dangerous chunk of ice is probably the Thwaites Glacier in Antarctica – so at risk it's called the "Doomsday Glacier". Thwaites Glacier is also called as Doomsday Glacier because it is one of Antarctica's fastest melting glaciers. And the threat of flooding quickly increases as sea levels rise. Like other glaciers, Thwaites has a long, thin tongue of ice that sticks out into seawater. And its structure seems to be too weak to sustain itself forever. It's also almost entirely below sea level. But if Thwaites melts enough that it lifts off, the ice sheet will be exposed, too. When it disappears, warm water can flood much further inland. Thwaites sits on a central edge of Antarctica's western sheet, and can be traced far inland. So its contribution to sea level rise is growing and could eventually get scary. We pay for your stories! Officially called the Thwaites Glacier, this mass of ice nestled into the western edge of Antarctica is melting at an alarming rate. In fact, it would be largely underwater if it wasn't for enormous barriers of glacial ice keeping the sea at bay. Over 30 years, the amount of ice flowing out of Thwaites and neighboring glaciers has nearly doubled. If Thwaites disappears, it risks destabilising huge parts of the west sheet. So if the entire sheet were to melt, it would pose huge problems for coastal areas around the world. A Glacier that Could End Us. But is it really at risk of disappearing, and how much damage would it cause? Thwaites glacier is larger the England and could drive global sea levels up by two feet (60cm) if it were to totally collapse. “If you were to zoom out and look at the whole picture, there's just this bright red spot to the edge of the West Antarctic Ice Sheet where Thwaites and [neighboring glacier] Pine Island are thinning like crazy.”, The rate at which Thwaites is slipping away and contributing to sea level rise is only half the reason researchers are concerned about its loss. The so-called Doomsday Glacier is really a Doomsday Nothing – other than a Doomsday Illustration of the flawed Climate Delusion. November 13, 2020 admin Science 0. 6 hours ago (Film for BBC Our World 2020) Antarctica is one of the most remote and inhospitable places on earth. Read more at Climate Realism. Deep channels discovered under the Antarctic's so-called 'Doomsday glacier' may be allowing warm ocean water to melt the underside of ice, according to … The glacier is roughly the size of Britain or Florida and already contributes to 4 per cent of sea-level rise each year. Antarctica is being melted from below by warm underground rivers, panicked scientists have warned. Basically Thwaites glacier is right on the edge of collapse. Governments also need to work on reducing their contribution to climate change to avoid accelerating any damage. By “do something,” Muto means addressing climate change, the force pushing Thwaites to melt. Journey to the Doomsday Glacier- Antarctica. Shutterstock.

Thwaites Glacier – what is it and why should we care? Researchers for the first time have discovered unusually warm water … ... That’s why Thwaites experts called it the “The End of the World Glacier”. But researchers still don’t know exactly how much of the glacier will melt or when, which makes it difficult to know if the ice sheet sitting beyond Thwaites will wash away, too. There is nothing to stop its accelerating retreat. Reporter Justin Rowlatt joins an international team of scientists travelling to Thwaites, the so-called Doomsday Glacier. The more sea levels rise, the more damage they can do to Antarctica's ice sheets. It’s a Matter of Adaptability, Researchers Say. If and when this might happen, however, is what researchers are trying to learn. But we also have to prepare for some of the inevitable sea level rise that is coming our way. EARTH’S most dangerous chunk of ice is probably the Thwaites Glacier in Antarctica – so at risk it’s called the “Doomsday Glacier”. It's also worth remembering that rising sea levels mean tsunamis and storm surges can reach much farther in land. Glaciers everywhere might be melting, but only one has earned the most terrifying nickname: the Doomsday Glacier. This service is provided on News Group Newspapers' Limited's Standard Terms and Conditions in accordance with our Privacy & Cookie Policy. But not all of Antractica's ice is doomed – and scientists hope much of it can be preserved. Officially called the Thwaites Glacier, this mass of ice nestled into the western edge of Antarctica is melting at an alarming rate. To be clear, Thwaites melting is concerning on its own. Officially called the Thwaites Glacier, this mass of ice nestled into the western edge of Antarctica is melting at an alarming rate. View our online Press Pack. Glaciologists have described Thwaites as the "most important" glacier in the world, the "riskiest" glacier, even the "doomsday" glacier. But it's not the worst bit. Think of Thwaites a bit like a keystone in an arch, holding everything together. The Thwaites Glacier is...a glacier. Note: The ice in Antarctica is so thick that it holds 90% of the world’s fresh water. The so-called Doomsday Glacier is really a Doomsday Nothing – other than a Doomsday Illustration of the flawed Climate Delusion. It's been described as the "Doomsday" glacier … This adds a real risk of collapse to the already fast-melting glacier.

Read Full Article. “It has really kind of been an incredible exercise, bringing together an extremely diverse range of scientific expertise,” Holschuh says. Human-caused climate change has warmed ocean waters that swirl around the grounding line. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of water. A massive one that poses such risk it's been branded the 'Doomsday Glacier". Called the International Thwaites Glacier Collaboration, the mission brings scientists (including Holschuh and Muto) down to the glacier to inspect how it’s changing through a barrage of studies. Antarctica is split into two main ice sheets: west and east. If they melted, they could destabilize the entire West Antarctic Ice Sheet, which has the potential to contribute about 10 feet to global sea level rise. This enormous hole is around 300 metres tall and roughly two-thirds the size of Manhattan. Their ability to learn more than ever before about the glacier puts a slightly positive spin on the Doomsday Glacier. 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. By Jeff Goodell. This isn't a new phenomenon: a huge area around Britain and Europe called Doggerland was once above sea level, but now rests at the bottom of the ocean. “But as long as we still have that potential for it to be bad, we need to be doing something about it so that we don’t actually tend towards that worst-case scenario.”. And unlike the currently melting glacier, the ice sheet extends into a pit in the Earth’s crust that gets as deep as 1.5 miles below sea level in some places. Officially called the Thwaites … The glacier is big and disappearing faster than others in the region. The Thwaites Glacier is...a glacier. Let us know in the comments! Loss of ice means faster melting generally, too. EARTH'S most dangerous chunk of ice is probably the Thwaites Glacier in Antarctica – so at risk it's called the "Doomsday Glacier".

The Thwaites Glacier, located in West Antarctica, has been called the ‘doomsday’ glacier and ‘the most important glacier’ in the world according to a group of scientists from the U.S. and UK. But that ice is already in the water, and therefore can't increase sea levels. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of water. It would be nearly impossible to predict how much sea levels will rise down to the exact inch, day, or year. If Thwaites melted, estimates suggest sea levels globally would rise around 0.5 metres on average. The concern over the fate of this particular patch of ice dates to the 1970s, when scientists published some of the first papers explaining how the very shape of Thwaites and the continent it connects to makes for precarious melting conditions. Britney Schmidt, a geophysicist at Georgia Tech, has, in a way, dove down to give the junction a close look. It’s sometimes called the Doomsday glacier — because its retreating faster all the time and calving larger and larger icebergs.

By Jeff Goodell. But worse more, Thwaites glacier is stopping four other glaciers from collapsing. The eastern sheet is actually reasonably safe in the short-term. As the ice disappears, the grounding line retreats and less of Thwaites sits on the rock. The project is a collaboration between the National Science Foundation and the U.K. Natural Environment Research Council, which independently recognized that Thwaites was a crucial but under-scrutinized glacier when it comes to understanding future sea level rise. We shouldn't underestimate that, and coastal areas need to work on flood defences. Article/Op-Ed in Rolling Stone. The Thwaites Glacier is...a glacier. May 9, 2017. If Thwaites melts away, that much-larger ice block will add water to our oceans as well, further driving up sea level rise. If you were to dive into the water beneath the protruding, visible ice and swim downward, you’d eventually see that Thwaites makes contact with rock. This interface is called the grounding line. A massive one that poses such risk it's been branded the 'Doomsday Glacier". A look at maps of the region’s ice loss makes this clear, says Nick Holschuh, a […] Many towns, cities and villages are built near oceans, because the sea is a great resource and makes trading easier. When we think of Antarctic ice, it's tempting to think of huge bergs floating through the sea. Note: The ice in Antarctica is so thick that it holds 90% of the world’s fresh water. A look at maps of the region's ice loss makes this clear, says Nick Holschuh, a geologist at Amherst College. Home Science Why Scientists Are So Worried About Antarctica’s Doomsday Glacier Why Scientists Are So Worried About Antarctica’s Doomsday Glacier. Here's what you need to know. The Doomsday Glacier In the farthest reaches of Antarctica, a nightmare scenario of crumbling ice – and rapidly rising seas – could spell disaster for a warming planet. Scientists are investigating how to slow or stop the glacier melting, but there's no concrete answer just yet. This is ironically true, as the fake climate scare of the Doomsday Glacier is really a doomsday for climate alarmism. It's a little smaller than Britain, so it's absolutely massive.
