Od ponad 500 lat \u017ceglarze poszukuj\u0105 wolnej od lodu trasy mi\u0119dzy arktycznymi wyspami p\u00f3\u0142nocnej Kanady. Wielu odkrywc\u00f3w straci\u0142o \u017cycie, pr\u00f3buj\u0105c odnale\u017a\u0107 Przej\u015bcie P\u00f3\u0142nocno-Zachodnie \u0142\u0105cz\u0105ce Ocean Atlantycki z Pacyfikiem. Jednak pokrywa lodowa Arktyki zacz\u0119\u0142a gwa\u0142townie si\u0119 kurczy\u0107. Nowe zdj\u0119cia radarowe uzyskane przez satelit\u0119 Envisat nale\u017c\u0105cego do ESA pokazuj\u0105, \u017ce powierzchnia arktycznego lodu morskiego jest obecnie najmniejsza od czasu rozpocz\u0119cia pomiar\u00f3w satelitarnych prawie 30 lat temu. Skutkiem tego jest tymczasowe otwarcie dotychczas nieprzejezdnego Przej\u015bcia P\u00f3\u0142nocno-Zachodniego.<\/p>\n<\/div>\n

Powierzchnia pokrywy lodowej Arktyki powi\u0119ksza si\u0119 podczas p\u00f3\u0142nocnej zimy i zmniejsza si\u0119 ka\u017cdego p\u00f3\u0142nocnego lata. Tempo letniej utraty lodu ulega jednak przyspieszeniu. Mozaika z\u0142o\u017cona z prawie 200 zdj\u0119\u0107 wykonanych przez satelit\u0119 Envisat we wrze\u015bniu 2007 roku wykaza\u0142a, \u017ce Przej\u015bcie P\u00f3\u0142nocno-Zachodnie by\u0142o w pe\u0142ni \u017ceglowne, podczas gdy Przej\u015bcie P\u00f3\u0142nocno-Wschodnie wzd\u0142u\u017c wybrze\u017ca Syberii by\u0142o zablokowane jedynie cz\u0119\u015bciowo.<\/p>\n

Du\u0144ski naukowiec Leif Toudal Pedersen powiedzia\u0142: \u201cZaobserwowali\u015bmy spadek powierzchni pokrytej lodem do zaledwie oko\u0142o 3 milion\u00f3w km\u00b2, czyli o oko\u0142o 1 milion km\u00b2 mniej ni\u017c w latach 2005 i 2006. W ci\u0105gu ostatnich 10 lat pokrywa lodowa zmniejsza\u0142a si\u0119 \u015brednio o oko\u0142o 100 000 km\u00b2 rocznie, wi\u0119c spadek o 1 milion km\u00b2 w ci\u0105gu zaledwie jednego roku jest zjawiskiem ekstremalnym\u201d.\u201d<\/p>","protected":false},"excerpt":{"rendered":"
