A NASA-funded study found instability in the Thwaites glacier meant there would probably come a point when it was impossible to stop it flowing into the sea and triggering a 50-cm sea level rise. Other Antarctic glaciers were likely to be similarly unstable. \u003Cstrong\u003EAlex Robel\u003C\/strong\u003E, an assistant professor at the US Georgia Institute of Technology\u0026nbsp;(School of Earth and Atmospheric Sciences) and the study\u0026rsquo;s leader, said if instability was triggered, the ice sheet could be lost in the space of 150 years, even if temperatures stopped rising. \u0026ldquo;It will keep going by itself and that\u0026rsquo;s the worry,\u0026rdquo; he said.The work was covered also by \u003Ca href=\u0022https:\/\/www.foxnews.com\/science\/glacier-sea-level-rise\u0022\u003EFox News\u003C\/a\u003E, \u003Ca href=\u0022https:\/\/www.dailymail.co.uk\/textbased\/sciencetech\/text-7225479\/Thwaites-Glaciers-worrying-melting-nearing-tipping-point.html\u0022\u003EDaily Mail\u003C\/a\u003E, \u003Ca href=\u0022https:\/\/www.upi.com\/Science_News\/2019\/07\/09\/Antarctic-ice-instability-could-yield-rapid-melting-dramatic-sea-level-rise\/7211562689513\/\u0022\u003EUPI\u003C\/a\u003E, \u003Ca href=\u0022https:\/\/www.cnn.com\/2019\/07\/10\/world\/antarctica-ice-sheet-sea-levels-trnd\/index.html\u0022\u003ECNN\u003C\/a\u003E, \u003Ca href=\u0022https:\/\/time.com\/5622632\/thwaites-glacier-antarctica-melting\/\u0022\u003ETime,\u003C\/a\u003E \u003Ca href=\u0022https:\/\/www.rnz.co.nz\/national\/programmes\/morningreport\/audio\/2018703636\/risk-of-major-sea-level-rise-when-antarctic-glacier-collapses\u0022\u003ERadio New Zealand\u003C\/a\u003E, \u003Ca href=\u0022https:\/\/cheddar.com\/media\/antarctic-glacial-melting-may-be-irreversible\u0022\u003ECheddar\u003C\/a\u003E, \u003Ca href=\u0022https:\/\/www.theweathernetwork.com\/ca\/news\/article\/whats-up-in-climate-change-europe-heat-wave-antarctic-sea-level-rise\u0022\u003EThe Weather Network\u003C\/a\u003E, and \u003Ca href=\u0022https:\/\/www.yahoo.com\/news\/glacier-size-florida-becoming-unstable-230515560.html\u0022\u003EYahoo News\u003C\/a\u003E.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"30678","created_gmt":"2019-07-10 17:23:47","changed_gmt":"2019-07-15 14:23:21","author":"A.
