De mai bine de 500 de ani, navigatorii caut\u0103 o rut\u0103 f\u0103r\u0103 ghea\u021b\u0103 \u00eentre insulele arctice din nordul Canadei. Mul\u021bi exploratori \u0219i-au pierdut via\u021ba \u00een \u00eencercarea de a g\u0103si un Pasaj de Nord-Vest care s\u0103 lege Oceanul Atlantic de Oceanul Pacific. Cu toate acestea, calota de ghea\u021b\u0103 arctic\u0103 a \u00eenceput s\u0103 se reduc\u0103 rapid. Noile imagini radar ob\u021binute de satelitul Envisat al ESA arat\u0103 c\u0103 suprafa\u021ba ghe\u021bii marine arctice se afl\u0103 acum la cel mai sc\u0103zut nivel de c\u00e2nd au \u00eenceput m\u0103sur\u0103torile prin satelit, \u00een urm\u0103 cu aproape 30 de ani. Rezultatul este deschiderea temporar\u0103 a Pasajului de Nord-Vest, care \u00eenainte era impracticabil.<\/p>\n<\/div>\n

Acoperirea de ghea\u021b\u0103 din Arctica cre\u0219te \u00een timpul iernii din emisfera nordic\u0103 \u0219i scade \u00een fiecare var\u0103 din emisfera nordic\u0103. Cu toate acestea, ritmul pierderii de ghea\u021b\u0103 din timpul verii se accelereaz\u0103. Un mozaic format din aproape 200 de imagini realizate de satelitul Envisat \u00een septembrie 2007 a ar\u0103tat c\u0103 Pasajul de Nord-Vest era complet navigabil, \u00een timp ce Pasajul de Nord-Est, de-a lungul coastei siberiene, era blocat doar par\u021bial.<\/p>\n

Cercet\u0103torul danez Leif Toudal Pedersen a declarat: \u201cAm observat c\u0103 suprafa\u021ba acoperit\u0103 de ghea\u021b\u0103 a sc\u0103zut la aproximativ 3 milioane de km\u00b2, ceea ce reprezint\u0103 cu aproximativ 1 milion de km\u00b2 mai pu\u021bin dec\u00e2t \u00een 2005 \u0219i 2006. \u00cen ultimii 10 ani, s-a \u00eenregistrat o reducere a stratului de ghea\u021b\u0103 de aproximativ 100.000 km\u00b2 pe an, \u00een medie, a\u0219a c\u0103 o sc\u0103dere de 1 milion de km\u00b2 \u00eentr-un singur an este extrem\u0103.\u201d<\/p>","protected":false},"excerpt":{"rendered":"
