Scientists know that the loss of Antarctic sea ice can diminish penguin numbers, cause ice shelves to melt in warmer waters, and impede the Southern Ocean from absorbing carbon dioxide.<\/p>\n<p>But this new research, published in the peer-reviewed journal Nature, explores another consequence: increased heat loss from the ocean to the atmosphere, and an associated rise in storms. Since 2016 there has been a large-scale reduction in Antarctic sea ice, but nothing like 2023 when a record amount failed to reform over the winter.<\/p>\n<p>For this study, Simon Josey of the UK\u2019s National Oceanography Centre and colleagues focussed on three regions that experienced unusually high levels of sea-ice retreat that year. Using satellite imagery, ocean and atmospheric data, and wind and temperature measurements, they found some newly ice-free areas experienced double the heat loss compared to a stabler period before 2015.<\/p>\n<p>This was accompanied by \u201cincreases in atmospheric-storm frequency\u201d over previously ice-covered regions, the authors found. \u201cIn the sea-ice-decline regions, the June\u2013July storm frequency has increased by up to 7\u2009days per month in 2023 relative to 1990\u20132015.\u201d<\/p>\n<p>The loss of heat caused by reduced sea ice could have implications for how the ocean circulates and the wider climate system, the study added. Oceans are a crucial climate regulator and carbon sink, storing more than 90 percent of the excess heat trapped near Earth\u2019s surface by greenhouse gas emissions. In particular, sea-ice retreat could mean changes in how a deeper layer of cold, dense Antarctic bottom water absorbs and stores heat.<\/p>\n<p>The authors said further in-depth analysis of possible climate impacts were needed, including if sea-ice retreat could have even further-reaching consequences. \u201cRepeated low ice-cover conditions in subsequent winters will strengthen these impacts and are also likely to lead to profound changes further afield, including the tropics and the Northern Hemisphere,\u201d it said.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.digitaljournal.com\/world\/melting-sea-ice-in-antarctica-causes-ocean-storms-scientists-say\/article\">DJ<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/csr-news-en\/melting-sea-ice-in-antarctica-causes-ocean-storms-scientists-say\/\">Melting sea ice in Antarctica causes ocean storms, scientists say<\/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":[1341,555,15305],"class_list":["post-136135","post","type-post","status-publish","format-standard","hentry","category-news","tag-antarctica","tag-csr-news-en","tag-melting-sea-ice"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/136135","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=136135"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/136135\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=136135"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=136135"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=136135"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
