Permafrost has accumulated large amounts of carbon and nitrogen over many millennia.\u00a0 Today, it holds 80% of the global peatland carbon and nitrogen stock, and presently serves as a net carbon sink. However, a 2\u00b0C temperature increase would thaw half of all such permafrost, converting 50% of it to emissions not taken up by increased plant growth. The authors conclude that we must remain below 2\u00b0C to prevent such carbon cycle climate feedback.<\/p>\n<p><a href=\"http:\/\/www.pnas.org\/content\/early\/2020\/08\/04\/1916387117\">http:\/\/www.pnas.org\/content\/early\/2020\/08\/04\/1916387117<\/a><\/p>\n<p>Compiled by Amy Imedieke<\/p>","protected":false},"excerpt":{"rendered":"<p>Proceedings of the National Academy of Sciences, August 10 Under high emissions scenarios, northern hemisphere permafrost and peatlands will show a 30-50% greater contribution to warming than previously projected, with emissions impacts equivalent to 1% of all anthropogenic radiative forcing this century \u2013 and this takes into account both peatland carbon uptake and permafrost thaw [&#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":"","footnotes":""},"categories":[152,9],"tags":[81,33,80,15,82,83,84],"class_list":["post-1750","post","type-post","status-publish","format-standard","hentry","category-cryosphere-capsules","category-latest-research","tag-carbon","tag-climate-change","tag-peatland","tag-permafrost","tag-sink","tag-source","tag-thaw"],"modified_by":"Pam Pearson","_links":{"self":[{"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts\/1750","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=1750"}],"version-history":[{"count":1,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts\/1750\/revisions"}],"predecessor-version":[{"id":1751,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/posts\/1750\/revisions\/1751"}],"wp:attachment":[{"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/media?parent=1750"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/categories?post=1750"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/iccinet.org\/sv\/wp-json\/wp\/v2\/tags?post=1750"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
