Muchos exploradores murieron en la b\u00fasqueda de un paso noroccidental que uniera los oc\u00e9anos Atl\u00e1ntico y Pac\u00edfico. Sin embargo, ahora la capa helada \u00e1rtica se reduce r\u00e1pidamente. Nuevas im\u00e1genes de radar obtenidas por el sat\u00e9lite Envisat de la ESA muestran que el hielo del mar \u00c1rtico se encuentra en su nivel m\u00e1s bajo desde que se iniciaron las mediciones por sat\u00e9lite hace casi 30 a\u00f1os. Como resultado se ha abierto temporalmente el Paso del Noroeste, que hasta ahora era infranqueable.<\/p>\n<\/div>\n<p>La cubierta de hielo \u00e1rtico aumenta en el invierno n\u00f3rdico y se reduce en cada verano del hemisferio norte. No obstante, las p\u00e9rdidas registradas durante el verano se est\u00e1n acelerando. Un mosaico de casi 200 im\u00e1genes captadas por el Envisat en septiembre 2007 mostraron que el Paso del Noroeste era totalmente navegable, en tanto que el Paso del Noreste, a lo largo de la costa siberiana, s\u00f3lo estaba bloqueado parcialmente.<\/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>Una zona libre de hielo del Paso del Noroeste en 2007<\/figcaption><\/figure>\n<p>El cient\u00edfico dan\u00e9s Leif Toudal Pedersen afirm\u00f3: \u201cHemos observado que la superficie cubierta de hielo se ha reducido a unos 3 millones de km\u00b2, lo que supone aproximadamente 1 mill\u00f3n de km\u00b2 menos que en 2005 y 2006.
