Det er fortsatt lenge til, men satellittobservasjoner viser en jevn nedgang i sn\u00f8mengden p\u00e5 den nordlige halvkule.<\/p>\n<\/div>\n<p>En ny analyse av sn\u00f8dekket, m\u00e5lt av satellitter som ESAs Envisat, viser at det har v\u00e6rt rekordlave sn\u00f8mengder i Europa og Asia hver juni siden 2008. I tillegg har tre av de siste fem \u00e5rene hatt rekordlavt sn\u00f8dekke i l\u00f8pet av de nordamerikanske somrene. Dette betyr at sn\u00f8dekket i juni n\u00e5 er det minste siden satellittobservasjonene startet for rundt 45 \u00e5r siden.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2003\/09\/Snowfall2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2003\/09\/snowfall2\/17906532-2-eng-GB\/Snowfall.jpeg\" alt=\"Snowfall\"><\/figure>\n<p>Det viser seg at sn\u00f8dekket i juni avtar mye raskere enn det klimamodellene hadde forutsagt, og sn\u00f8en forsvinner til og med raskere enn sommerisen i Arktis. Satellittm\u00e5linger viser ogs\u00e5 at den maksimale sn\u00f8mengden p\u00e5 den nordlige halvkule gradvis avtar, mens v\u00e5rsn\u00f8en \u2013 s\u00e6rlig mot Nordpolen \u2013 smelter tidligere.<\/p>\n<p>Har det noen betydning om det er mindre sn\u00f8 og om den smelter raskere? Endringer i sn\u00f8massen og sn\u00f8dekket har stor innvirkning p\u00e5 vannmengden i isbreer, elver og jord. De henger ogs\u00e5 sammen med langsiktige klimaendringer.<\/p>\n<p>Det er kanskje ikke bare julenissen som m\u00e5 endre livsstilen sin i fremtiden\u2026<\/p>","protected":false},"excerpt":{"rendered":"<p>Will Santa Claus one day need wheels for his sleigh?
