By Eric Holthaus on Nov 21, 2017 When the sea water is cold, this process is very slow, the ice pump usually just melts a few dozen centimetres a year - easily balanced by the new ice created by falling snow. “Because it’s uncertain, Thwaites has the potential to really be the Doomsday Glacier. The heat received by that so-called "doomsday" glacier is > > barely enough to keep the temperature from dropping through the floor. The Big Melt book. The glacier earned its ominous "doomsday" nickname because it's one of Antarctica's fastest melting glaciers. AN ENORMOUS lump of ice dubbed the "world's most dangerous glacier" is teetering on the verge of collapse, threatening to raise global sea levels by an unprecedented eight feet. (via BBC Science News) The so-called doomsday glacier in Western Antarctica called Thwaites glacier is the size of Britain and is known to be melting at an alarming rate. Read reviews from world’s largest community for readers. The Doomsday Glacier ... which in turn increases the rate of melt. In some areas, complex interactions between wind and ocean circulation patterns have helped to push naturally occurring warm water closer to the edge of the ice. This is still a phenomenon that scientists are studying. Some call it the Doomsday Glacier. Melt water is fresh and therefore relatively light. If the glacier were to melt, it would drain a mass of water the size of Great Britain. If those glaciers also melt, sea levels could rise an additional eight feet, researchers warn. 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. Eos (2020, January 10) Controlled Explosions Pave the Way for Thwaites Glacier Research. > > Rolling Stone should stick to music reviews. At the same time, parts of the glacier want to float, which places additional stress on the ice, causing it to fracture. Thwaites Glacier in Antarctica is 74,000 square miles, the size of Great Britain, and is thought to be particularly susceptible to climate change. Climate change: What Antarctica's 'doomsday glacier' means for the planet 19 Jul, 2020 02:22 AM 11 minutes to read Antarctica hold crucial clues about the future of the planet. But the glacier also backstops neighboring glaciers. References & Resources. As the glacier melts, the fresh water therefore tends to flow upwards, drawing up the heavier warmer sea water behind it. EARTH'S most dangerous chunk of ice is probably the Thwaites Glacier in Antarctica – so at risk it's called the "Doomsday Glacier". The long device was slid 600 metres deep into the Thwaites glacier through a narrow hole and had a bunch of sensors and sonar cameras. To find out more, scientists will soon be dodging crevasses on Thwaites to deploy drills that use hot water to tunnel down through the ice and then place sensors either side of the grounding line. It has also been dubbed the Doomsday glacier. Scientists warn Thwaites Glacier in Antarctica – the "doomsday glacier" – is melting more rapidly than they thought. Thwaites glacier in West Antarctica is enormous and is often referred to as the most dangerous glacier on Earth. The team, dubbed MELT, or Melting at Thwaites grounding zone and its control on sea level, spent the last two months in -30C weather at the glacier for the project. Teams of scientists are drilling into a huge glacier – described as the “doomsday glacier” – to find out if it’s about to collapse. Interestingly, human activity is not responsible for all the causes of glacier melt. Already, ice draining from Thwaites accounts for about 4 … These devices on the Icefin discovered that the Doomsday Glacier, in fact, is suffering from the ocean that’s warming up more than the air, causing most of its ice to melt. Antarctica's Doomsday Glacier melting away faster than previously thought ... That broken ice spread almost 160km wide with hundreds of billions of tonnes of melt water is pouring into the sea. 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 … Accessed February 9, 2020. The Big Melt: A Journey to Antarctica's Doomsday Glacier: Goodell, Jeff, Goodell, Jeff: Books Scientists have detected unusually warm water underneath Antarctica's "doomsday glacier." Scientists have made a surprising discovery of warm water under a huge glacier which is the cause behind its gradual depletion. 'Doomsday Glacier' melting quickly from the inside, ... the channels surrounding the glacier which they believe are providing access for warm water that is causing it to melt. Doomsday scenarios. The BBC's Justin Rowlatt has recently got back from a joint UK-US expedition to find out what's going on. Ice Apocalypse Rapid collapse of Antarctic glaciers could flood coastal cities by the end of this century. Dubbed the “doomsday” glacier, Thwaites, perhaps more than any other place in the world, ... Ice takes time to melt and heat takes time to distribute through the climate system. BBC News (2020, January 28) Antarctica melting: Climate change and the journey to the ‘doomsday glacier.’ Accessed February 5, 2020. 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. It also has the potential to not be so bad,” Muto says. Scientists alarmed to discover warm water at "vital point" beneath Antarctica's "doomsday glacier" By Sophie Lewis February 1, 2020 / 1:34 PM / CBS News 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. The glaciers of Pine Island Bay are two of the largest and fastest-melting in Antarctica. David Holland: So, it's less than a meter. That exposes more of a glacier's underside to sea water, increasing the likelihood its melt rate will accelerate. The glacier … Over 30 years, the amount of ice flowing out of Thwaites and neighboring glaciers has nearly doubled. The vital question is when. Accessed February 5, 2020. International Thwaites Glacier Collaboration (2020) About the ITGC. If Thwaites were to melt or drop into the sea tomorrow, how much sea level rise would we expect? The aim is to watch ice crossing the line over the next two years to see how fast the glacier's underside is moving. There’s no doubt this ice will melt as the world warms.
