En mosaik best\u00e5ende av n\u00e4stan 200 bilder som togs av Envisat i september 2007 visade att Nordv\u00e4stpassagen var helt farbar, medan Nordostpassagen l\u00e4ngs den sibiriska kusten endast var delvis blockerad.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1186\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2007\/09\/A_2007_ice-free_portion_of_the_Northwest_Passage2\" 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\/2007\/09\/a_2007_ice-free_portion_of_the_northwest_passage2\/17885582-2-eng-GB\/A_2007_ice-free_portion_of_the_Northwest_Passage.jpg\" alt=\"A 2007 ice-free portion of the Northwest Passage\"><figcaption>En isfri del av Nordv\u00e4stpassagen fr\u00e5n 2007<\/figcaption><\/figure>\n<p>Den danske forskaren Leif Toudal Pedersen sa: \u201cVi har sett att den isbelagda ytan har minskat till drygt 3 miljoner kvadratkilometer, vilket \u00e4r ungef\u00e4r 1 miljon kvadratkilometer mindre \u00e4n under 2005 och 2006.
