This stark shift is detailed in the National Oceanic and Atmospheric Administration\u2019s 2024 Arctic Report Card, which revealed that annual surface air temperatures in the Arctic this year were the second-warmest on record since 1900.<\/p>\n<p>\u201cOur observations now show that the Arctic tundra, which is experiencing warming and increased wildfire, is now emitting more carbon than it stores, which will worsen climate change impacts,\u201d said NOAA Administrator Rick Spinrad.The finding is based on average of observations recorded from 2001-2020. Climate warming exerts dual effects on the Arctic. While it stimulates plant productivity and growth, which remove carbon dioxide from the atmosphere, it also leads to increased surface air temperatures that cause permafrost to thaw.<\/p>\n<p>Thawing permafrost releases carbon previously trapped in frozen soil as carbon dioxide and methane \u2014 two potent greenhouse gases \u2014 through microbial decomposition. In 2024, Alaska recorded its second-warmest permafrost temperatures on record, the report said. Human-caused climate change is also intensifying high-latitude wildfires, which have increased in burned area, intensity, and associated carbon emissions. Wildfires not only combust vegetation and soil organic matter, releasing carbon into the atmosphere, but they also strip away insulating soil layers, accelerating long-term permafrost thaw and its associated carbon emissions.<\/p>\n<p>Since 2003, circumpolar wildfire emissions have averaged 207 million tons of carbon annually, according to NOAA. At the same time, Arctic terrestrial ecosystems have remained a consistent source of methane. \u201cLast year, 2023, was the largest fire year on record due to Canadian wildfires, which burned more than twice any other year on record in Canada,\u201d report co-author Brendan Rogers said during a press conference. The fires emitted nearly 400 million tons of carbon \u2014 more than two-and-a-half times the emissions from all other sectors in Canada combined, he added.Meanwhile, 2024 ranked as the second-highest year for wildfire emissions within the Arctic Circle.<\/p>\n<p><a rel=\"noopener\" href=\"https:\/\/www.digitaljournal.com\/world\/sink-to-source-arctic-is-now-emitting-more-carbon-than-it-absorbs\/article\">Read more&gt;&gt;<\/a><\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.digitaljournal.com\/world\/sink-to-source-arctic-is-now-emitting-more-carbon-than-it-absorbs\/article\">Digital Journal<\/a><\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/csr-news-en\/sink-to-source-arctic-is-now-emitting-more-carbon-than-it-absorbs\/\">Sink to source: Arctic is now emitting more carbon than it absorbs<\/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":[17262,1682,555,17263],"class_list":["post-135965","post","type-post","status-publish","format-standard","hentry","category-news","tag-absorbs","tag-arctic","tag-csr-news-en","tag-emitting-more-carbon"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/135965","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=135965"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/135965\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=135965"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=135965"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=135965"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
