Now those sponges are at the centre of a bold and controversial claim made in a leading scientific journal that, since the start of the Industrial Revolution, the planet may have already warmed by 1.7C \u2013 half a degree more than estimates used by the United Nation\u2019s climate panel.<\/p>\n<p>With the help of deep-sea divers, six specimens of Ceratoporella nicholsoni \u2013 a sponge that can take hundreds of years to grow between 10cm and 15cm \u2013 were removed from areas off the coast of Puerto Rico and the US Virgin Islands. As the sponges grow, they store strontium and calcium in a ratio that relates directly to the temperature of the water around them. The sponges grow deep enough to be unaffected by natural fluctuations in temperature and in an area of the ocean, the authors said, where temperature changes closely match the global average.<\/p>\n<p>The sponges had also recorded a sudden drop in temperatures caused by a massive volcanic eruption in Indonesia in 1815, giving them confidence the sponges were a good proxy for temperature. But the sponges also showed that current warming started in 1860. The UN\u2019s Intergovernmental Panel on Climate Change considers the \u201cpre-industrial\u201d period to be between 1850 and 1900 and global heating rates are benchmarked against that 50-year period. The findings and claims by their authors that the globe had breached a key warming milestone were challenged by several leading climate scientists.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.theguardian.com\/environment\/2024\/feb\/06\/ancient-sea-sponges-at-centre-of-controversial-claim-world-has-already-warmed-by-17c\">Guardian<\/a><\/p>\n<p><p>&nbsp;<\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/6-463\/\">Ancient sea sponges at centre of controversial claim world has already warmed by 1.7C<\/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":[13248,575,13249],"class_list":["post-125136","post","type-post","status-publish","format-standard","hentry","category-news","tag-caribbean-sea","tag-environmental-news-en","tag-sea-sponge"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/125136","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=125136"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/125136\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=125136"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=125136"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=125136"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
