The unprecedented event reminded Joel Harper, a University of Montana glaciologist who works on the Greenland ice sheet, of a strange anomaly in his data, one that suggested that in 2008 it might have rained much later in the season \u2014 in the fall, when the region is typically in deep freeze and dark for almost 24 hours a day.<\/p>\n<p>When Harper and his colleagues closely examined the measurements they\u2019d collected from sensors on the ice sheet those many years ago, they were astonished. Not only had it rained, but it had rained for four days as the air temperature rose by 30 degrees C (54 degrees F), close to and above the freezing point. It had warmed the summit\u2019s firn layer \u2014 snow that is in transition to becoming ice \u2014 by between 11 and 42 degrees F (6 and 23 degrees C). The rainwater and surface melt that followed penetrated the firn by as much as 20 feet before refreezing, creating a barrier that would alter the flow of meltwater the following year.<\/p>\n<p>All that rain is significant because the melting of the Greenland ice sheet \u2014 like the melting of other glaciers around the world \u2014 is one of the most important drivers of sea level rise. Each time a rain-on-snow event happens, says Harper, the structure of the firn layer is altered, and it becomes a bit more susceptible to impacts from the next melting event. \u201cIt suggests that only a minor increase in frequency and intensity of similar rain-on-snow events in the future will have an outsized impact,\u201d he says. <a rel=\"noopener\" href=\"https:\/\/e360.yale.edu\/features\/arctic-rainfall-climate-change\"><strong>Read more at: Yale Environment 360\u00a0<\/strong><\/a><\/p>\n<p>Soure: <a rel=\"noopener\" href=\"https:\/\/www.enn.com\/articles\/74142-rain-comes-to-the-arctic-with-a-cascade-of-troubling-changes\">ENN<\/a> <\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/vaufien\/rain-comes-to-the-arctic-with-a-cascade-of-troubling-changes\/\">Rain Comes to the Arctic, With a Cascade of Troubling Changes<\/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":[606,607,608],"class_list":["post-125547","post","type-post","status-publish","format-standard","hentry","category-news","tag-vau_viikkokatsaus","tag-vauen","tag-vaufien"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/125547","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=125547"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/125547\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=125547"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=125547"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=125547"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
