Environment ‘Doomsday glacier’ melting due to warm water channels, scientists say. Already, Thwaites accounts for about four per cent of global sea-level rise as warming waters cause it to melt from the underside. The question then is what we choose to do about it. This image pair demonstrates the changes that have occurred since the start of this century. Posted by.

Scent of lemons can make you feel thinner and lighter but vanilla makes you feel heavier, study finds. That would be devastating for low-lying coastal communities. 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. None of the protections necessary to preserve coastal communities will come cheap. The Thwaites Glacier is one of the most dangerous glaciers in the world, and scientists are eager to travel to Antarctica to study it. Thwaites Glacier doomed? “You'd expect it might lead to even further acceleration of flow of the glacier,” Larter said of the blowout. “We could be observing it right now and not really realize that it’s happening, and that’s pretty scary to think about.”. 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. It is up to 4,000 meters thick and is considered a key in making projections of global sea level rise. If Thwaites were to collapse, it could lead to an increase in sea levels of around 25 inches (64 centimeters) -- and the researchers are trying to find out how soon this is likely to happen. Scientists fear the collapse of Thwaites Glacier could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. The comments below have not been moderated. What we don't know is how much of an impact that will have on the ice sheet surrounding Thwaites – because it's very difficult to model. Satellite images soon showed where these icebergs were coming from. But the IPCC, too, serves up its estimates with an important caveat, stating that “the collapse of the marine-based sectors of the Antarctic ice sheet, if initiated, could cause [global mean sea level] to rise substantially above the likely range during the 21st century.”. Coupled with the thinning of the glacier and its faster flow, “this [event] is one expression of the fact that Thwaites Glacier is putting more and more ice into the ocean.”.

It would drain a mass of water that is roughly the size of Great Britain or the state of Florida and currently accounts for approximately 4 percent of global sea-level rise. But the wide range of scenarios possible by 2100 makes planning for century’s end impossible, according to Alisha Pegan, coordinator of the city’s Climate Ready Boston program. Because its interior connects to the vast portion of the West Antarctic Ice Sheet that lies deeply below sea level, the glacier is considered a gateway to the majority of West Antarctica’s potential sea level contribution. As part of the wider project a number of robotic vehicles have been sent under the ice to gather data including one called Rán - named after the Norse god of the sea, The team were able to use data gathered by the robot to create a detailed map of the sea floor underneath the glacier. Melting of Thwaites is cause for global concern as its sheer enormity means that it contains enough ice that, if it was to melt, there would be worldwide implications. A run-away collapse of the glacier would lead to a significant increase in sea levels of around 65cm (25 inches) and scientists want to find out how quickly this could happen. When we think of Antarctic ice, it's tempting to think of huge bergs floating through the sea. Once the glacier has retreated to a certain point, the tall cliffs of ice may crumble under their own weight. Thwaites sits on a central edge of Antarctica's western sheet, and can be traced far inland. A 'doomsday' Antarctic glacier that could collapse within decades and cause a 10ft (3 metre) rise in sea levels will be studied by an 'unprecedented' joint US-UK mission.

Palmer became the first ship to sail across the 75-mile face of West Antarctica’s Thwaites Glacier, a piece of its floating ice shelf bigger than Manhattan crumbled off the glacier into a flotilla of icebergs. The Thwaites glacier covers an area around half the size of the UK Antarctica's ice – what's going on? How Antarctica ‘Doomsday Glacier’ Thwaites could COLLAPSE and send sea levels soaring. Scientists think we could see a total collapse of the glacier within the next century, and are scrambling to better understand how to save it. Is Thwaites Glacier doomed? u/nrtlbwlitw. 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. A 2014 study looked by the union of concerned scientists looked at 52 sea level indicators in communities across the US. The Thwaites glacier is the size of Florida and is located in the Amundsen Sea. A recent study put the price tag of protecting the US from rising seas over the next two decades at more than $400 billion. Researchers sent a robotic submersible called Rán - named after the Norse god of the sea - under the ice at Thwaites Glacier and discovered streams of warm water, Researchers are studying Thwaites in detail, with various ongoing studies. In a future where carbon emissions continue unabated, warming air temperatures would force its collapse within 250 years. It is a crucial site for glacial melt and warm water is coming from three different directions, a new study has found. This big blowout confirmed that there's very little actual ice shelf left in the western part of Thwaites Glacier. It is up to 4,000 metres (13,100 feet thick) and is considered a key in making projections of global sea level rise. The key to West Antarctica’s future is the Thwaites glacier. The United Nations Intergovernmental Panel on Climate Change projects between roughly 1 1/2 to 3 feet of sea level rise under a “business as usual” carbon emissions scenario, or 1 to 2 feet if we start cutting carbon immediately and dramatically. Scientists think the glacier could undergo even more dramatic changes in the near future. A previous answer “A 2ft rise in sea level is a blip.” said Are you kidding me ? Thwaites’ demise alone could have significant impact globally. Scientists have found warm water underneath the Thwaites Glacier in Antarctica, which could speed up the melting of the Florida-sized block of ice. Maybe 15 feet. 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. Instead, much of the ice there is actually what scientists call a “mélange,” a slushy mix of icebergs and other floating bits of ice formed by fracturing at an ice front. This image pair demonstrates the changes that have occurred since the start of this century. “They filled in a lot of the [Boston] Harbor with horses and shovels,” Wormser said, “and they never contemplated sea level rise.”. But even the city government isn’t sure that level of protection is possible. Scientists fear the collapse of Thwaites Glacier could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. And how fast it might happen once it starts. If Thwaites collapses, much of the West Antarctic Ice Sheet could follow it into the ocean. Thwaites, about the size of Florida, is currently responsible for about 4 percent of global sea level rise, making it one of the most dangerous glaciers in the world, according to scientists. If Thwaites were to collapse, it could lead to an increase in sea levels of around 64cm - and the researchers are trying to find out how soon this is likely to happen. Scientists fear the collapse of Thwaites Glacier could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. This means that one chunk of ice crumbling could mean the entire glacier gives way. The rate of Thwaites’s disintegration has alarmed scientists for good reason. In Boston, much of the current downtown didn’t exist prior to the arrival of European settlers. Think of Thwaites a bit like a keystone in an arch, holding everything together. Sometimes called the Doomsday Glacier due to the potential impact its collapse could have on sea levels, Thwaites is unusually broad and fast. This single glacier is responsible for 4% of global sea level rise. “I don't have an answer for that,” Pegan said when asked if it was even feasible to protect Boston from 11 feet of sea level rise. Each scenario includes only a small amount of melting from Antarctica. It already drains an area roughly the size of Britain or the US state of Florida, accounting for around four per cent of global sea-level rise —an amount that has doubled since the mid-1990s. For Boston, it’s something the city plans to adapt to. Shocking moment a giant iceberg three times the size of... Groundbreaking footage of Antarctica's 'doomsday' Thwaites... Scientists drill into Antarctica's 'doomsday' Thwaites... What lies beneath? Roughly 90% of an ice sheet typically sits below the water line. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of water. Thwaites Glacier is in West Antarctica and is sometimes called the Doomsday Glacier due to its potential impact on global sea levels. Close. Many low-lying coastal cities, from the US to the Netherlands to Bangladesh, are built on land partially reclaimed from the sea. It could also be on the verge of a rapid collapse. But it's not the worst bit. In the UK, a two metre (6.5 ft) rise by 2040 would see large parts of Kent almost completely submerged, according to the results of a paper published in Proceedings of the National Academy of Science in November 2016. A map showing what the land is like underneath the ice on Antarctica created as part of the wider project is helping scientists predict the impact of global warming on the frozen continent - they used data from seismology and air surveys. The Florida-sized glacier extends deep into the heart of the Antarctica ice sheet. Produced by Ian Coss, Steven Davy, David Evans, Alex Newman, Anna Pratt and Peter Thomson. “It's another step in the [progressive] retreat,” Larter said. As the ice shelf thins, it lifts away from the seafloor and loses its ability to act as a brake on the flow of ice from the continent. Scientists fear the collapse of Thwaites Glacier could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. In the UK, for instance, a rise of 6.7ft (2 metres) or more may cause areas such as Hull, Peterborough, Portsmouth and parts of east London and the Thames Estuary at risk of becoming submerged. Other groups will look at the glacier's flow on land and the ocean circulation - with all of the research feeding into models of the glacier and its future. Livable Planet. In 2001, a study of Thwaites Glacier using satellite radar interferometry data from the Earth Remote Sensing Satellite 1 and 2 revealed that the grounding line of Thwaites Glacier was retreating at 1 kilometer per year and that the glacier was significantly out of mass balance, hence confirming presumptions of collapse by Terence Hughes, University of Maine, in 1973. This submarine’s historic tour under Thwaites Glacier will help scientists predict sea level rise, On a journey to Antarctica, a New Orleans chef awakens to the threat of melting ice, These high-tech seals are charting future sea level rise, These scientists used small explosions to 'see' under Antarctica and measure how fast a key glacier will melt, For this marine tech, Antarctica’s Thwaites Glacier drives home threat of climate change, more than a quarter of the population would face inundation. Scientists are investigating how to slow or stop the glacier melting, but there's no concrete answer just yet. And it's melting very quickly, which is a huge concern to scientists. A roughly 20-mile stretch of Thwaites had fractured into mile-long icebergs that were now being blown out into the bay in front of Thwaites. What we do know is that as seas warm and rise, Thwaites will be under increasing threat. The collapse of the glacier, which could begin with decades, could also submerge major cities such as New York and Sydney. Teams of scientists are drilling into a huge glacier – described as the “doomsday glacier” – to find out if it’s about to collapse. From 1992 to 2011, the centre of the Thwaites grounding line retreated by nearly 14 kilometres (nine miles). This means that cities and countries using IPCC data to build their own localized sea level rise projections are likewise only planning for a small amount of loss from West Antarctica, which might prove to be an underestimation. The city of Boston is planning for more than 3 feet of sea level rise by 2070, and between 2 and 7 feet by 2100. This winter’s expedition aboard the Palmer marked the first field season of a five-year, international research collaboration to discover just how much, and how fast, Thwaites Glacier might add to rising seas. The ice shelf is stabilized by contact with the seafloor. u/nrtlbwlitw. If Thwaites retreats far enough inland and reaches a certain thickness, physics dictates it will start collapsing under its own weight. Close. The questions swirling around the future of the West Antarctic ice sheet add to the considerable uncertainty policymakers and planners face when trying to prepare for sea level rise. “We’d like to plan for 2100. Some communities are going beyond these national and international projections and incorporating potential melting from Antarctica’s ice sheets into their local sea level rise estimates. Glaciers are huge sheets of ice moving very slowly, and contain vast amounts of water. It might not be a name familiar to the US market, but Naim is a legendary British brand hoping to make a splash with the American launch of its $1499 Mu:So speaker. 266. The Thwaites Glacier is...a glacier. Five dedicated teams of scientists and engineers have been working on Thwaites Glacier for the last two months in below freezing temperatures and extreme winds. New, not-yet-published research from the same pair revises the estimate for the end of the century downward substantially, but the longer-term picture is still bleak, with a rate of sea level rise that could “be very challenging for coastal planners and engineers to cope with,” DeConto wrote in an email, “likely leading to large-scale retreat from the coast in some places and loss of some low lying islands.”. 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. And that's a concern.”. Eleven feet of sea level rise, which would come from the collapse of the entire West Antarctic ice sheet, is another story entirely. But what Thwaites and the glaciers around it have in store could be much more significant. “Is it over a century, over a thousand years, or can you do in a decade? Twenty of these communities could see a tripling or more in tidal flooding events. The Thwaites Glacier is one of the most dangerous glaciers in the world, and scientists are eager to travel to Antarctica to study it. The Thwaites glacier has experienced significant flow acceleration since the 1970s. At 11 feet, much of the city would be underwater without massive, new infrastructure projects to protect it. Science Thwaites Glacier, a sheet of ice about the size of Florida, lies in West Antarctica. We are no longer accepting comments on this article. Flight window is open! Their 2016 research, which predicts how marine ice cliffs will react to atmospheric warming under a variety of future greenhouse gas scenarios, found that in a future where we quickly and radically cut greenhouse gas emissions, the West Antarctic ice sheet would be relatively stable for centuries. Antarctica's Thwaites glacier has warm water from three directions well under it threatening to destroy the ice sheet and raise global sea levels by up to two feet. If Thwaites melted, estimates suggest sea levels globally would rise around 0.5 metres on average. AI seems to permeate every part of its software, from the ability to answer calls for you to being able to almost perfectly predict your morning commute. Five dedicated teams of scientists and engineers have been working on Thwaites Glacier for the last two months in below freezing temperatures and extreme winds. Many scientists believe this process is already under way but the speed of collapse remains unknown. Boston, of course, is not alone, nor is it the most vulnerable. Warm water from the deep ocean is welling up under the glacier from three different directions and mixing under the ice, the researchers discovered. 266. The Thwaites glacier is slightly smaller than the total size of the UK, approximately the same size as the state of Washington, and is located in the Amundsen Sea. In the near term, these changes will mean more frequent, coastal flooding in low-lying areas, including some of Boston’s most historic neighborhoods. In the US, just half that amount of sea level rise could prompt a coastal exodus that would rival the great migration. It’s difficult to calculate exact timelines for this glacier collapse, mostly because glaciers have a threshold that when met, the whole thing crumbles. 1 month ago. Scientists race against time to find out. The latest findings from a study into the wider ice shelf the glacier sits on come two years into the five year project. The Thwaites Glacier is receding by half a mile per year. Thwaites Glacier in Antarctica is 74,000 square miles, the size of Great Britain, and is thought to be particularly susceptible to climate change. Using radar to study the inside of the shelf they found it was full of channels, ridges and cliffs created by warm currents. Scientists fear an unstoppable flow of ice from the Thwaites Glacier into the sea Credit: SWNS:South West News Service If Thwaites disappears, what happens? Climate. This is the last in a series, Into the Thaw: Decoding Thwaites Glacier. Scientists may just have identified Thwaites Glacier's Achilles heel. Researchers have long held concerns that a tipping point in the stability at its foundations could result in a run-away collapse of the glacier. Google is late to the game with its Home Hub, but the low price and AI features make it a great choice for controlling your home, showing pictures and even helping run your life. Satellite images of the western portion of the Thwaites ice front on March 2, 2019, and on March 6, 2019, after a large section of what had previously been called “ice shelf” crumbled into a flotilla of icebergs. If it collapses it could take other parts of the ice shelf with it and lead to the single largest driver of sea-level rise this century, lead researcher Erin Pettit told Nature. Maybe 15 feet. The Thwaites Glacier is receding by half a mile per year. 'We've never seen an ice sheet disintegrate in a warming climate, so we're struggling to project how it could happen,' glaciologist Ted Scambos told Nature. Vietnam, for example, where more than a quarter of the population would face inundation if the entire West Antarctic ice sheet were to collapse, uses IPCC data in its national climate report. The seafloor underneath the glacier slopes downward as it goes inland in what scientists call a “retrograde slope,” and the ice sitting on top of it gets thicker and thicker. They are studying the wider shelf, which extends across more than 65miles of open ocean and acts as a cork holding back ice on land, Pettit said. Many climate scientists regard Thwaites glacier in West Antarctica as one of the most vulnerable and most significant glaciers in the world in terms of future global sea-level rise. As part of two new studies into the glacier, teams of US and UK scientists scanned Thwaites from above and below. Scientists fear the collapse of Thwaites Glacier could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. The mid-Atlantic coast is expected to see some of the greatest increases in flood frequency. Scientists think we could see a total collapse of the glacier within the next century and are scrambling to better understand how to save it. Israeli beauty-tech firm Pollogen has launched its Geneo Personal device, which stimulates oxygen from beneath the skin's surface to give you a clearer, fresher face within minutes. Peloton's hi-tech bike lets you stream live and on demand rides to your home - and it's one of the best examples of fitness technology out there - at a price. Thwaites Glacier in Antarctica is 74,000 square miles, the size of Great Britain, and is thought to be particularly susceptible to climate change. When we think of Antarctic ice, it's tempting to think of huge bergs floating through the sea. Read More. Now, about a third of Boston is at risk of coastal flooding if sea levels rise between 2 and 8 feet higher than they are today, Wormser said.

But what Thwaites and the glaciers around it have in store could be much more significant. The £39million study involving UK and US scientists was launched after concerns the increasingly unstable glacier may have already started to collapse. Thwaites is already losing twice as much ice a year as it was in the late 1990s. Computer modeling shows Thwaites is unstable, and could start collapsing within decades. Glaciologist Erin Pettit and her team worked directly on the ice shelf conducting seismic tests to study the sea floor and deploy sensor 980ft into the ice. “Our challenge is that [sea levels are] going to keep going up,” said Julie Wormser from the Boston-area Mystic River Watershed Association. Published: 10:06, 21 February 2020 | Updated: 14:36, 21 February 2020. On one hand, the XR lacks the high-resolution screen and dual-lens camera on the XS. The area surveyed had been hidden beneath part of the floating ice shelf extending from Thwaites Glacier, which broke off in 2002, … Thwaites’ ice shelf stabilizes the whole glacier, acting like a cork in a wine bottle to slow the seaward flow of ice from the continent’s interior. An iceberg in the Southern Ocean, is pictured here as the Nathaniel B. Palmer sailed by during its return trip from Antarctica in March 2019. If every country met its Paris Agreement commitments, the world would warm to 2.7 degrees Celsius. She said by then we should know much more about the risks the ice shelf poses. Into the Thaw: Decoding Thwaites Glacier The two bigger glaciers are shielding ice that, if melted, would contribute to significant sea-level rise around the world. Places such as Annapolis, Maryland and Washington, DC can expect more than 150 tidal floods a year, and several locations in New Jersey could see 80 tidal floods or more. “The entire embayment where we’d been working for several days was littered with icebergs.”. Posted by. Thwaites is split into two sections - a stable eastern side with a rocky outcrop and flows of about 1,900ft per year and a  western side with flows of 1.2 miles per year. Parts of New Orleans, Houston and Miami in the south on the US would also be particularly hard hit. Scientists think we could see a total collapse of the glacier within the next century, and are scrambling to better understand how to save it. “You have to think in terms of maybe 3 feet, but maybe 10 or 15,” Alley said. 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. Pacific Island nations like Kiribati, the Marshall Islands and the Maldives would be wiped off the map if the West Antarctic ice sheet were to collapse entirely. The ship is the length of a football field and dwarfs a nearby cruise ship. “What we didn’t realize at the time is the ice [front] was coming out to chase us out,” said Rob Larter, a marine geophysicist at the British Antarctic Survey and chief scientist on the ship. The Thwaites glacier covers an area around half the size of the UK Antarctica's ice – what's going on? The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. 1 month ago. The first image, acquired with the Enhanced Thematic Mapper Plus (ETM+) on Landsat 7, shows the glacier’s floating ice tongue on December 2, 2001 shortly before it calved Iceberg B-22. But it is a sign of the glacier’s instability. If the entire floating ice shelf at Thwaites fractures into icebergs, what’s left at the edge of the glacier is a giant cliff of ice whose shape makes it particularly vulnerable to runaway collapse. Scientists fear its collapse could one day destabilize surrounding glaciers and eventually trigger up to 11 feet of global sea level rise. Like other glaciers, Thwaites has a long, thin tongue of ice that sticks out into seawater. The city is working with communities to develop neighborhood plans focusing on solutions like raised parks along Boston Harbor that serve both as spaces for recreation and flood barriers. If you were to dive into the water beneath the protruding, … Thwaites Glacier, a sheet of ice about the size of Florida, lies in West Antarctica. As part of the wider project a number of robotic vehicles have been sent under the ice to gather data including one called Rán - named after the Norse god of the sea. It's just the science right now is so uncertain that it's planning for a variance of 4 feet of sea level rise,” Pegan said. Glaciers contribute to sea-level rise when more ice is lost to the ocean that is replaced by snow. “You have to think in terms of maybe 3 feet, but maybe 10 or 15,” Alley said. NASA As Thwaites glacier nears collapse, scientists worry that ramifications like the disappearance of West Antarctic are a mere decade away. Global sea levels could rise as much as 10ft (3 metres) if the Thwaites Glacier in West Antarctica collapses. Read More A team of scientists from Oregon State University made the most of ice free waters in West Antarctica to look under the glacier - which is about the size of Great Britain. Scientists recently discovered that warm undercurrents could be eating away its underbelly. “When we have better data, better science, then we can make more informed decisions.”. The seafloor underneath the glacier slopes downward as it goes inland in what scientists call a “retrograde slope,” and the ice sitting on top of it gets thicker and thicker. Areas on the south coast like Portsmouth, as well as Cambridge and Peterborough would also be heavily affected. The five genes that make you more likely to die from coronavirus or be admitted to intensive care. The United States’ National Climate Assessment estimates we’ll see 1-4 feet of sea level rise by 2100, citing the complicated dynamics of Greenland’s and Antarctica’s ice sheets as “the primary reason that projections of global sea level rise includes such a wide range of plausible future conditions.”.
