Antarctica’s oldest ice has arrived in the UK for analysis which scientists hope will reveal more about Earth’s climate shifts.<\/p>\n

The ice was retrieved from depths of up to 2,800 metres at Little Dome C in East Antarctica as part of an international effort to “unlock the deepest secrets of Antarctica’s ice”.<\/p>\n

The ice cores – cylindrical tubes of ancient ice – will be analysed at the British Antarctic Survey (BAS) in Cambridge, with the ultimate goal of reconstructing up to 1.5 million years of Earth’s climate<\/a> history, significantly extending the current ice core record of 800,000 years.<\/p>\n

The research is also expected to offer valuable context for predicting future climate change, Dr Liz Thomas, head of the ice cores team at the British Antarctic Survey, said.<\/p>\n

Over the next few years, the samples will be analysed by different labs across Europe to gain understanding of Earth’s climate evolution and greenhouse gas concentrations.<\/p>\n

Dr Thomas said: “It’s incredibly exciting to be part of this international effort to unlock the deepest secrets of Antarctica’s ice.<\/p>\n

“The project is driven by a central scientific question: why did the planet’s climate cycle shift roughly one million years ago from a 41,000-year to a 100,000-year phasing of glacial-interglacial cycles?<\/p>\n

“By extending the ice core record beyond this turning point, researchers hope to improve predictions of how Earth’s climate may respond to future greenhouse gas increases.”<\/p>\n

The ice was extracted as part of the Beyond EPICA – Oldest Ice project, which is funded by the European Commission and brings together researchers from 10 European countries and 12 institutions.<\/p>\n

“Our data will yield the first continuous reconstructions of key environmental indicators-including atmospheric temperatures, wind patterns, sea ice extent, and marine productivity-spanning the past 1.5 million years,” Dr Thomas said.<\/p>\n

“This unprecedented ice core dataset will provide vital insights into the link between atmospheric CO\u2082 levels and climate during a previously uncharted period in Earth’s history, offering valuable context for predicting future climate change.”<\/p>\n","protected":false},"excerpt":{"rendered":"Antarctica’s oldest ice has arrived in the UK for analysis which scientists hope will reveal more about Earth’s…\n","protected":false},"author":2,"featured_media":5467,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[64,63,75,128],"class_list":["post-5466","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-au","tag-australia","tag-environment","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/5466","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=5466"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/5466\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/5467"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=5466"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=5466"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=5466"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
