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 ramifications for many countries, including most of the world’s coastal cities, would be catastrophic. At its thickest point, the ice sheet is almost three miles deep. The ocean also absorbs excess heat from greenhouse gas emissions and warm water expands, taking up more space than colder water. The burning of fossil fuels ramped up during the Industrial Revolution in the mid-18th century, increasing levels of carbon dioxide (CO2) in the atmosphere. But is it really at risk of disappearing, and how much damage would it cause? Is the ‘Big One’ Coming for Los Angeles? 'Doomsday Glacier' Teetering at Edge of Collapse? The Thwaites glacier is 74,000 square miles, roughly the size of the UK. Warmer temperatures melt ice sheets and glaciers, leading the run-off to flow into oceans. But it's Thwaites protective effect on neighbouring glaciers that Nasa is most worried about. The existing Open Comments threads will continue to exist for those who do not subscribe to Independent Premium. Weakness in doomsday glacier the size of BRITAIN could send sea levels soaring by two feet. "Thanks to a new generation of satellites, we can finally see the detail," he said. Due to the sheer scale of this comment community, we are not able to give each post the same level of attention, but we have preserved this area in the interests of open debate. "As more heat and water get under the glacier, it melts faster.". As it grows, Thwaites will disintegrate faster and faster, potentially triggering a global catastrophe. In interviews with the Financial Times , several scientists noted that the collapse of the ice mass - which has been referred to as the “doomsday glacier” - could increase sea levels by around 65 centimeters by itself. It seems to be teetering at the edge,” Paul Cutler, programme director for Antarctic glaciology at America’s National Science Foundation told the Financial Times this week. Researchers expected to find some gaps between ice and bedrock at Thwaites' bottom where ocean water could flow in and melt the glacier from below. View our online Press Pack. Both the Antarctic and Arctic regions are warming faster than the rest of the world but in the Arctic temperatures have hit record highs, with an alarming all-time high of 38C recorded in Siberia in June. 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. Camera Captures Dramatic Landslide in India 00:29. Our rapidly-warming planet causes sea levels to rise on two fronts. Scientists drill into Antarctic ‘doomsday glacier’ to see if it will collapse and flood the world. Thwaites Glacier, a huge glacier in the Antarctic, is often called the Doomsday Glacier.

The greenhouse gas absorbs heat from the sun and traps it, heating the atmosphere and the planet. 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. Previous research has predicted that a 6ft sea level rise would leave large parts of Kent underwater, while Portsmouth, Cambridge and Peterborough wouldn't fair much better. Earlier this year a team of scientists observed, for the first time, the presence of warm water at a vital point underneath the glacier, which helps explain the reason behind the extent of its decrease. Nasa has discovered a gigantic cavity under the Thwaites Glacier in West Antarctica that they say could destabilise the doomsday ice block and topple it into the sea.
