Given projected warming even with very low emissions, these findings indicate that sections of the West Antarctic Ice Sheet may collapse even without any additional greenhouse emissions and related warming; but risks will increase as temperatures approach 2\u00b0C. A low emissions pathway must be followed to avoid crossing this apparent 2\u00b0C threshold, and irreversibly committing ourselves to more than 4 meters of additional sea-level rise from the WAIS.<\/p>\n<p><a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1029\/2021GL094513\" rel=\"noopener\" target=\"_blank\">https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1029\/2021GL094513<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Scientific Reports, August 19 During the Last Inter-Glacial (LIG, between ice ages) 125,000 years ago, ocean temperatures rose 1.5-2\u00b0C above pre-industrial levels.
