Still Waters Posted November 14, 2018 #1 Share Posted November 14, 2018 A "hotspot" is melting the base of the Antarctic Ice Sheet at the South Pole. The area affected is three times that of Greater London. Scientists suspect a combination of unusually radioactive rocks and geothermal springs may be responsible. The warm bedrock is removing some 6mm a year from the underside of the 3km-thick ice sheet, producing a mass of meltwater that then flows away through sub-glacial rivers and lakes towards the continent's coastline. The roughly 100km-by-50km hotspot came to light when researchers examined radar images of the ice sheet at 88 degrees South. https://www.bbc.co.uk/news/science-environment-46202255 4 1 Link to comment Share on other sites More sharing options...
