Essentially, the paper shows that 1\u00b0C warming relative to 1880-1920 keeps global temperature within the Holocene range, the current geological epoch that human life has adapted to; while warming of 2\u00b0C could cause \u201cmajor dislocations for civilization.\u201d The paper\u2019s point is well taken, 1\u00b0C warming is safer and we only get one shot at this.<\/p>\n<p>How much can we burn to stay below 1\u00b0C? Using a simple carbon model, the scientists calculate that we can burn another 130 GtC (477 Gt CO2). If we assume that emissions are growing at 2% a year we will burn through this in another 11 years. As with any calculation based on the future, there are some assumptions built in. In this case, the authors assume climate-friendly\/favourable changes to land use emissions and non-CO2 forcings \u2013 meaning that the remaining budget may be even smaller than they calculated. But the message is clear, we need to limit fossil fuels CO2 emissions and fast.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jim Hansen, Jeffrey Sachs and a gaggle of other scientists and economists published a research paper last Tuesday titled, Assessing<span class=\"text-cutoff\">&#8230;<\/span><\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[46],"class_list":["post-4785","post","type-post","status-publish","format-standard","hentry","category-uncategorized","tag-hansen"],"acf":[],"_links":{"self":[{"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/posts\/4785","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/comments?post=4785"}],"version-history":[{"count":0,"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/posts\/4785\/revisions"}],"wp:attachment":[{"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/media?parent=4785"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/categories?post=4785"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gofossilfree.org\/usa\/wp-json\/wp\/v2\/tags?post=4785"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
