Permanenta ist\u00e4cken har funnits vid nord- och sydpolen i miljontals \u00e5r. Men dramatiska f\u00f6r\u00e4ndringar p\u00e5g\u00e5r vid v\u00e4rldens tak. Nya satellitm\u00e4tningar visar att havsisen i Arktis har blivit tunnare och b\u00f6rjat brytas upp.<\/p>\n<\/div>\n

Bilder som togs mellan den 23 och 25 augusti 2006 visar f\u00f6r f\u00f6rsta g\u00e5ngen dramatiska \u00f6ppningar i det permanenta havsiset. Dessa str\u00e4cker sig fr\u00e5n \u00f6n Svalbard och \u00f6ver den ryska Arktis \u00e4nda till Nordpolen \u2013 ett omr\u00e5de som \u00e4r st\u00f6rre \u00e4n de brittiska \u00f6arna.<\/p>\n

Radarbilder fr\u00e5n ESA:s Envisat visar \u00f6ppningar i isen som m\u00f6rkgr\u00e5 och svarta omr\u00e5den. Satelliten Aqua visar omr\u00e5den med uppbruten is i gult, orange och gr\u00f6nt. Sammanlagt br\u00f6ts omkring 5\u201310 procent (upp till en tiondel) av den is som \u00f6verlevt sommaren upp av stormarna i augusti.<\/p>\n

\u201cDen h\u00e4r situationen skiljer sig fr\u00e5n allt vi tidigare sett under s\u00e4songer med rekordl\u00e5ga isniv\u00e5er\u201d, s\u00e4ger Mark Drinkwater fr\u00e5n ESA:s enhet f\u00f6r hav och is.<\/p>\n

Enligt Drinkwater kan ismassan ha varit s\u00e5 uppbrytad att ett fartyg l\u00e4tt skulle ha kunnat segla fr\u00e5n Sibirien till Nordpolen \u2013 n\u00e5got som normalt sett skulle vara om\u00f6jligt. F\u00f6rst under de senaste veckorna har havet b\u00f6rjat frysa till igen.<\/p>\n

Under de senaste 25 \u00e5ren har satelliter observerat att isen i Arktis krymper alltmer under sommarens sm\u00e4lts\u00e4song. I b\u00f6rjan av 1980-talet t\u00e4ckte sensommarisarna cirka 8 miljoner kvadratkilometer. F\u00f6rra \u00e5ret var arealen mindre \u00e4n 5,5 miljoner kvadratkilometer. Dessa f\u00f6r\u00e4ndringar tillskrivs allm\u00e4nt den globala uppv\u00e4rmningen.<\/p>","protected":false},"excerpt":{"rendered":"
