Nov\u00e1 satelitn\u00ed m\u011b\u0159en\u00ed ukazuj\u00ed, \u017ee mo\u0159sk\u00fd led v Arktid\u011b se zten\u010duje a rozpad\u00e1.<\/p>\n<\/div>\n

Sn\u00edmky po\u0159\u00edzen\u00e9 ve dnech 23. a\u017e 25. srpna 2006 poprv\u00e9 zachycuj\u00ed dramatick\u00e9 mezery v trval\u00e9m mo\u0159sk\u00e9m ledu.

Radarov\u00e9 sn\u00edmky z dru\u017eice Envisat agentury ESA zobrazuj\u00ed mezery v ledu jako tmav\u011b \u0161ed\u00e9 a \u010dern\u00e9 oblasti. Dru\u017eice Aqua zn\u00e1zor\u0148uje oblasti rozbit\u00e9ho ledu \u017elutou, oran\u017eovou a zelenou barvou. Celkov\u011b bylo asi 5\u201310 procent (a\u017e jedna desetina) ledu, kter\u00fd p\u0159e\u010dkal l\u00e9to, rozbit\u00e9 srpnov\u00fdmi bou\u0159emi.<\/p>\n

\u201cTato situace se li\u0161\u00ed od v\u0161eho, co jsme dosud pozorovali v p\u0159edchoz\u00edch sez\u00f3n\u00e1ch s rekordn\u011b n\u00edzk\u00fdm pokryt\u00edm ledem,\u201d uvedl Mark Drinkwater z odd\u011blen\u00ed pro oce\u00e1ny a led agentury ESA.<\/p>\n

Podle Drinkwatera mohl b\u00fdt ledov\u00fd p\u0159\u00edkrov natolik rozt\u0159\u00ed\u0161t\u011bn\u00fd, \u017ee lo\u010f mohla snadno plout ze Sibi\u0159e k severn\u00edmu p\u00f3lu \u2013 co\u017e by za norm\u00e1ln\u00edch okolnost\u00ed bylo nemo\u017en\u00e9.
