But when a local reporter contacted Walter Anthony, who is a research professor at the Institute of Northern Engineering at University of Alaska Fairbanks, to inspect the waterbed-like ground at a nearby golf course, she started to pay attention. Like others in Fairbanks, they lit \u201cturf bubbles\u201d on fire and confirmed the presence of methane gas.<\/p>\n<p>Then, when Walter Anthony looked at nearby sites, she was shocked that methane wasn\u2019t just coming out of a grassland. \u201cI went through the forest, the birch trees and the spruce trees, and there was methane gas coming out of the ground in large, strong streams,\u201d she said. \u201cWe just had to study that more,\u201d Walter Anthony said.<\/p>\n<p>With funding from the National Science Foundation, she and her colleagues launched a comprehensive survey of dryland ecosystems in Interior and Arctic Alaska to determine whether it was a one-off oddity or unforeseen concern. Their study, published in the journal Nature Communications this July, reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. Even more, the methane consisted of carbon thousands of years older than what researchers had previously seen from upland environments. \u201cIt\u2019s a totally different paradigm from the way anyone thinks about methane,\u201d Walter Anthony said.<\/p>\n<p>Because methane is 25 to 34 times more potent than carbon dioxide, the discovery brings new concerns to the potential for permafrost thaw to accelerate global climate change.The findings challenge current climate models, which predict that these environments will be an insignificant source of methane or even a sink as the Arctic warms.<\/p>\n<p>Typically, methane emissions are associated with wetlands, where low oxygen levels in water-saturated soils favor microbes that produce the gas. Yet methane emissions at the study\u2019s well-drained, drier sites were in some cases higher than those measured in wetlands. This was especially true for winter emissions, which were five times higher at some sites than emissions from northern wetlands.<\/p>\n<p><a rel=\"noopener\" href=\"https:\/\/www.eurekalert.org\/news-releases\/1054083\">Read more &gt;&gt;<\/a><\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.eurekalert.org\/news-releases\/1054083\">Eurekalert<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/researchers-find-unexpectedly-large-methane-source-in-overlooked-landscape\/\">Researchers find unexpectedly large methane source in overlooked landscape<\/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":[575,15655],"class_list":["post-132980","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-large-methane-source"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/132980","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=132980"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/132980\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=132980"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=132980"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=132980"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
