Research published today in Nature Geoscience said when compared to a pre-1700 baseline, the planet reached the temperature increase at the end of 2023. The figure is higher than globally accepted estimates of about 1.3C of warming, as highlighted in the United Nations&#8217;s latest emissions gap report, which is based on historical temperature observations from 1850 to 1900.<\/p>\n<p>Scientists adopted the 1850 to 1900 time period for the simple reason it had the earliest reliable temperature data from land and sea observations around the world. Reliable and consistently recorded temperatures pre-1850 that cover the Industrial Revolution, which occurred from about 1760 to 1840, are sparse. Dr Jarvis said other scientists had been able to measure the concentration of CO2 in bubbles in layers of ice that corresponded with different time periods. By using the CO2 ice records from Law Dome in East Antarctica, Dr Jarvis and his co-author, climate physicist Piers Forster from the University of Leeds, could then estimate historical temperatures.<\/p>\n<p>Dr Jarvis said the method could still be run with the existing baseline period of 1850 to 1900. By using the study&#8217;s methodology for this time period it also showed, like studies using sea and land temperature, there had been 1.3C of warming but with less statistical uncertainty.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.abc.net.au\/news\/science\/2024-11-12\/climate-change-warming-limit-close-antarctic-ice-reveals\/104585566\">ABC<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/4-625\/\">World close to 1.5C warming limit according to new pre-industrial temperature estimate<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[575,1170,904],"class_list":["post-135316","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-temperature","tag-warming"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/135316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=135316"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/135316\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=135316"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=135316"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=135316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
