Nasa found a huge growing cavity under Thwaites while examining ice-penetrating satellite imagery of Thwaites. 00:48. Scientists drill into Antarctic ‘doomsday glacier’ to see if it will collapse and flood the world. For about 2,000 years until the late 1800s, global sea levels remained almost static with small fluctuations. 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. Scientists previously found the extent of the instability of the Antarctic ice sheet difficult to study but improved technologies are allowing greater insight into the changes in the ice on, and surrounding, the continent. 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. “If you remove it, other ice will potentially start draining into the ocean too.”, Rob Larter, UK principal investigator for the Thwaites Glacier Project at the British Antarctic Survey, added: “It is the most vulnerable place in Antarctica.”. Warmer temperatures melt ice sheets and glaciers, leading the run-off to flow into oceans. Its collapse would raise global sea levels by more than half a metre on its own, and subsequently release other major bodies of ice in West Antarctica, which together could raise sea levels by 2-3 metres. Antarctica accounts for vast quantities of ice – around 90 per cent of all ice in the world - and unlike in the Arctic, most of the ice is out of the water and on land. The annual rate of sea-level rise has roughly doubled since 1990. Thwaites glacier is losing ice at an accelerating rate, threatening catastrophic sea-level rise, Find your bookmarks in your Independent Premium section, under my profile.

'Doomsday Glacier' Teetering at Edge of Collapse? “It seems to be teetering at the edge.” By itself, Thwaites could raise sea levels about 65cm as it melts. The greenhouse gas absorbs heat from the sun and traps it, heating the atmosphere and the planet. The cylindrical robot was lowered down a 600m-deep hole just 35cm in diameter to measure the waters moving below the glacier's surface. The average thickness of the ice is 1.6 miles deep.
