But it’s receding by about half a mile per year. the doomsday glacier. While it has been shrinking since the early 1990s, ice loss has almost doubled over the past 20 years. In total, the icebergs measure about twice the size of Washington, D.C., in area (more than 130 square miles, or 350 square kilometers), according to The Washington Post. That is somewhat on the grounds that the Thwaites, a Britain-sized glacier in western Antarctica, is liquefying at a disturbing rate. Are you worried about climate change? SCIENTISTS have laid bare the vulnerability of an enormous glacier in Antarctica that scientists say is teetering on the edge of collapse. Notice the size of the glacier’s main ice tongue in 2001, when the glacier was advancing by about 4 kilometers per year. It is equivalent to a continent the size of Europe, covered in a blanket of ice 2km thick. 'Doomsday Glacier' melting quickly from the inside, British Antarctic Survey shows ... Thwaites glacier, which is roughly the size of Great Britain, … Its fastest flowing grounded ice is centred between 50 and 100 kilometres (31 and 62 mi) east of Mount Murphy. By Jonathan Amos BBC Science Correspondent. Thwaites glacier in West Antarctica are enormous in size and often referred to as the most dangerous glacier on Earth. Scientists say Antarctica’s so-called “doomsday glacier” is “teetering at the edge.” Here’s what may be in store. "The Sun", "Sun", "Sun Online" are registered trademarks or trade names of News Group Newspapers Limited. It is massive - roughly the size of Britain. The Thwaites Glacier has been called the "doomsday" glacier and the "most important" glacier in the world, BBC News explained. And, experts think melting Antarctic ice could cause areas of the ocean to turn a "deep green" colour by 2100. Scientists think this cavity is a major cause of the ice loss seen at the glacier. Scientists will use the new data to create models that can help them to better predict the glacier's behaviour in future. For further details of our complaints policy and to make a complaint please click this link: thesun.co.uk/editorial-complaints/, Comments are subject to our community guidelines, which can be viewed, , Senior Digital Technology and Science Reporter, New maps reveal that channels carrying warm water along the Antarctic sea bed are the likely culprits for the gradual collapse of the Thwaites glacier, Thwaites glacier is said to be 'the most vulnerable place in Antarctica', Scientists mapped channels that carry warm water to the underside of Thwaites glacier, Two recent studies mapped above and below the huge glacier, Dramatic footage shows 120ft 'tower block' of ice splitting off from Antarctic glacier, melted from below by warm underground rivers, areas of the ocean to turn a "deep green" colour, Independent Press Standards Organisation (IPSO), Scientists have lots of evidence to show that the Earth’s climate is rapidly changing due to human activity, Climate change will result in problems like global warming, greater risk of flooding, droughts and regular heatwaves, Each of the last three decades have been hotter than the previous one and 17 of the 18 warmest years on record have happened during the 21, The Earth only needs to increase by a few degrees for it to spell disaster, The oceans are already warming, polar ice and glaciers are melting, sea levels are rising and we’re seeing more extreme weather events, In 2015, almost all of the world's nations signed a deal called the Paris Agreement which set out ways in which they could tackle climate change and try to keep temperatures below 2C. The glacier, roughly the size of Britain or Florida, already contributes four percent a year to global sea level rise. Scientists will use the new data to create models that can help them to better predict the glacier's behaviour in future. In other news, the first full map of the hidden continent below Antarctica has been revealed. ", She added: "Because they are so deep, and so wide - this allows a lot more water to get at, and melt, Thwaites' floating front as well as its ice that rests on the seabed.". Think of six football pitches back to back. For other inquiries, Contact Us. News Corp is a network of leading companies in the worlds of diversified media, news, education, and information services. Channels carrying warm water along the Antarctic sea bed are thought to be the killer factor driving the glacier's dramatic demise, new maps show. And, experts think melting Antarctic ice could cause areas of the ocean to turn a "deep green" colour by 2100. Thwaites glacier is larger the England and could drive global sea levels up by two feet (60cm) if it were to totally collapse. Let us know in the comments! "The connected channels that we've mapped are the potential pathways for deep-ocean warm water to get in and do damage," BAS's Dr Tom Jordan said. We pay for your stories! The collapse of the 74,000-square-mile Thwaites — which some scientists see as the most vulnerable and significant glacier in the world when it comes to sea-level-rise — could release a … Thwaites glacier is larger the England and could drive global sea levels up by two feet (60cm) if it were to totally collapse. "[The size of] a cavity under a glacier plays an important role in melting," said Nasa scientist Dr Pietro Milillo. The Thwaites glacier is 74,000 square miles, roughly the size of the UK. "These channels had not been mapped before in this kind of detail," Dr Kelly Hogan from the British Antarctic Survey (BAS) told BBC News. Now researchers think they've unearthed the "critical link" between the ocean and the base of the melting glacier. Teams of scientists are drilling into a huge glacier – described as the “doomsday glacier” – to find out if it’s about to collapse.
