But tree rings, which record temperature information far further back than even Victorian scientific records, now show just how unprecedented last year&#8217;s scorching temperatures were. Researchers say that temperatures last June, July and August were nearly 4C warmer than the coldest summer two millennia ago.<\/p>\n<p>Climate scientists have repeatedly shown that global temperatures have been rising rapidly in recent decades. According to the UN&#8217;s climate body, the last time the world was consistently this warm may have been more than 100,000 years ago. These conclusions come from records like ice cores and deep sea sediments, which can give a good indication of the Earth&#8217;s geological past, but cannot pinpoint individual years or even decades far back in time. For this, tree rings are particularly valuable. They not only show the tree&#8217;s age, but also record detailed information about the state of the climate each year as they grow.<\/p>\n<p>The authors combined the long-term tree ring record with modern temperature data. They found that the summer of 2023 was 2.07C warmer than the &#8220;pre-industrial&#8221; period of 1850-1900. Compared with the coldest summer in the record, year 536, last summer was 3.93C warmer. Like many colder years, 536 was impacted by a large volcanic eruption which put more sulphur into the atmosphere, helping to cool the planet. Researchers say the tree ring information is a huge addition to what we know about our changing climate over history. Even in the 1850-1900 period, there were only 58 weather stations recording temperatures around the world, with 45 of them in Europe.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.bbc.com\/news\/articles\/c72pp3yqzjyo\">BBC<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/6-514\/\">Ancient trees reveal last summer hottest in 2,000 years<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","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":[14514,575,1170,14515],"class_list":["post-130380","post","type-post","status-publish","format-standard","hentry","category-news","tag-ancient-trees","tag-environmental-news-en","tag-temperature","tag-tree-rings"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/130380","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=130380"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/130380\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=130380"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=130380"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=130380"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
