The paper says ocean temperatures during the last interglacial were likely up to 2C warmer than they are today and global sea levels were 6-9 metres higher. Sarri is the word for pack ice, tuvaqtaq is bottom-fast ice, and shore-fast ice is tuvaq. To trace Antarctica’s potential contribution to this sea-level rise, the scientists travelled to West Antarctica to the Patriot Hills Blue Ice Area, which is on the periphery of the West Antarctic ice sheet. Sea levels will rise by a further 17cm and put 16 million people at risk of yearly coastal flooding if global warming continues apace, British and Danish researchers warned. The latest measurements show the world’s seas are now rising by 4mm each year. Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel for Climate Change's (IPCC) most extreme forecasts, which see the two ice sheets adding up to 40 centimetres (nearly 16 inches) to global oceans by 2100, they reported in Nature Climate Change.. An ice sheet, also known as a continental glacier, is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 km (19,000 sq mi). The Patriot Hills Blue Ice Area, in the Antarctic, where a research team discovered high sea levels during the last interglacial period were due to a rise of less than 2C in ocean temperature. That’s enough to double the frequency of storm-surge flooding in many of the world’s largest coastal cities.”. Blue ice areas are created by katabatic winds. He said the research also suggested this mass melting happened quite early during the ocean warming “somewhere between zero and 2C”. “. They used some shallow drilling to take ice samples from the surface. Sea level rise is a natural consequence of the warming of our planet. Mass melting of the West Antarctic ice sheet, driven by warmer ocean temperatures, was a major cause of extreme sea level rise more than 100,000 years ago, according to new research. “It means that a large part of the west Antarctic almost certainly disappeared in the last interglacial. “What these results suggest, or show, is that when people talk about a 2C warmer world as a good thing, actually what it shows is we don’t want to get close to 2C,” he said. Greenland lost billions of tonnes of ice to global warming last year, Ice sheets melting at ‘worst-case scenario’ rate, Greenland lost 1 million tonnes of ice for each minute of 2019, The looming climate disaster that no one is talking about, Scientists warn of rapid melting of Antarctica’s ‘Doomsday glacier’, You may not agree with our views, or other users’, but please respond to them respectfully, Swearing, personal abuse, racism, sexism, homophobia and other discriminatory or inciteful language is not acceptable, Do not impersonate other users or reveal private information about third parties, We reserve the right to delete inappropriate posts and ban offending users without notification.

When these winds blow over mountains, they remove snow and ice, allowing ancient ice to come to the surface. But Ruth Mottram, climate researcher at the Danish Meteorological Institute, said: “It is not only Antarctica and Greenland that are causing the water to rise.
