The authors conclude that by not meeting the Paris Agreement, more than one such critical threshold might be crossed, committing us to ever-higher long-term sea-level rise.<\/p>\n<p><a href=\"https:\/\/www.nature.com\/articles\/s41586-020-2727-5\">https:\/\/www.nature.com\/articles\/s41586-020-2727-5<\/a><\/p>\n<p>Compiled by Amy Imdieke<\/p>","protected":false},"excerpt":{"rendered":"<p>Nature, September 23 The rate and scale of ice loss from Antarctica will increase as temperatures exceed 2\u00b0C, according to new modeling from the Potsdam Institute.\u00a0 At global warming up to 2\u00b0C above pre-industrial, Antarctica would lose enough ice mass to increase global sea-levels by 1.3 m per each degree of warming.\u00a0 From 2\u00b0C to [&#8230;]\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[152,9],"tags":[],"class_list":["post-1831","post","type-post","status-publish","format-standard","hentry","category-cryosphere-capsules","category-latest-research"],"modified_by":"Pam Pearson","_links":{"self":[{"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts\/1831","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/comments?post=1831"}],"version-history":[{"count":1,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts\/1831\/revisions"}],"predecessor-version":[{"id":1832,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts\/1831\/revisions\/1832"}],"wp:attachment":[{"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/media?parent=1831"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/categories?post=1831"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/tags?post=1831"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
