Det har v\u00e6rt permanente iskapper p\u00e5 Nord- og S\u00f8rpolen i millioner av \u00e5r. Men det skjer dramatiske endringer p\u00e5 toppen av verden. Nye satellittm\u00e5linger viser at havisen i Arktis har blitt tynnere og brutt opp.<\/p>\n<\/div>\n

Bilder tatt mellom 23. og 25. august 2006 viser for f\u00f8rste gang dramatiske \u00e5pninger i den faste havisen. Disse strekker seg fra \u00f8ya Svalbard og tvers over den russiske Arktis helt til Nordpolen \u2013 et omr\u00e5de som er st\u00f8rre enn De britiske \u00f8yer.<\/p>\n

Radarbilder fra ESAs Envisat viser \u00e5pninger i isen som m\u00f8rkegr\u00e5 og svarte omr\u00e5der. Aqua-satellitten viser omr\u00e5der med oppbrutt is i gult, oransje og gr\u00f8nt. Totalt ble rundt 5\u201310 prosent (opptil en tidel) av isen som overlevde sommeren brutt opp av stormene i august.<\/p>\n

\u201cDenne situasjonen skiller seg fra alt vi har sett i tidligere sesonger med rekordlav isutbredelse,\u201d sa Mark Drinkwater fra ESAs avdeling for hav og is.<\/p>\n

If\u00f8lge Drinkwater kan isdekket ha v\u00e6rt s\u00e5 oppbrutt at et skip lett kunne ha seilt fra Sibir til Nordpolen \u2013 noe som normalt ville v\u00e6rt umulig. F\u00f8rst de siste ukene har havet begynt \u00e5 fryse til igjen.<\/p>\n

I l\u00f8pet av de siste 25 \u00e5rene har satellitter observert at isen i Arktis har krympet stadig mer i l\u00f8pet av sommerens smeltesesong. P\u00e5 begynnelsen av 1980-tallet dekket sensommerisen et omr\u00e5de p\u00e5 rundt 8 millioner kvadratkilometer. I fjor var det mindre enn 5,5 millioner kvadratkilometer. Disse endringene tilskrives i stor grad global oppvarming.<\/p>","protected":false},"excerpt":{"rendered":"
