Na ji\u017en\u00edm p\u00f3lu sv\u011bta hroz\u00ed, \u017ee obrovsk\u00fd ledovec ve tvaru l\u00e1hve zni\u010d\u00ed v\u0161e, co mu stoj\u00ed v cest\u011b. A kosmick\u00e1 lo\u010f Envisat agentury ESA sleduje ka\u017ed\u00fd jeho pohyb.<\/p>\n<\/div>\n

Ka\u017ed\u00e9 l\u00e9to se od chladn\u00e9ho ji\u017en\u00edho kontinentu Antarktidy odlamuj\u00ed obrovsk\u00e9 kusy plovouc\u00edho ledu. V b\u0159eznu 2000 se v\u0161ak stalo n\u011bco v\u00fdjime\u010dn\u00e9ho, kdy\u017e se od Rossova ledov\u00e9ho \u0161elfu odlomil blok o velikosti Jamajky.<\/p>\n

V pr\u016fb\u011bhu n\u00e1sleduj\u00edc\u00edch n\u011bkolika let se nejv\u011bt\u0161\u00ed zn\u00e1m\u00fd ledovec na sv\u011bt\u011b rozpadl na mnoho kus\u016f. Nejv\u011bt\u0161\u00ed kus, zn\u00e1m\u00fd jako B-15A, se nakonec dostal do McMurdo Sound, kde zablokoval oce\u00e1nsk\u00e9 proudy a zp\u016fsobil nahromad\u011bn\u00ed mo\u0159sk\u00e9ho ledu.<\/p>\n

To zp\u016fsobilo pot\u00ed\u017ee z\u00e1sobovac\u00edm lod\u00edm, kter\u00e9 se sna\u017eily dostat k v\u011bdeck\u00fdm stanic\u00edm. Z\u00e1rove\u0148 to znamenalo, \u017ee nadm\u011brn\u00e9 mno\u017estv\u00ed mo\u0159sk\u00e9ho ledu od\u0159\u00edzlo tu\u010d\u0148\u00e1ky od jejich obvykl\u00fdch lovi\u0161\u0165.<\/p>\n

V posledn\u00edch t\u00fddnech se ledovec B-15A postupn\u011b p\u0159ibli\u017eoval k dlouh\u00e9mu ledov\u00e9mu v\u00fdb\u011b\u017eku, kter\u00fd zasahuje do mo\u0159e. Na za\u010d\u00e1tku ledna se vzd\u00e1lenost mezi nimi zmen\u0161ila na m\u00e9n\u011b ne\u017e 4 km.<\/p>\n

V\u011bdci o\u010dek\u00e1vali, \u017ee budou sv\u011bdky sr\u00e1\u017eky gigant\u016f, kdy\u017e se ledovec B-15A z\u0159\u00edtil do plovouc\u00edho ledovcov\u00e9ho jazyka Drygalski. M\u00edsto toho se v\u0161ak zd\u00e1lo, \u017ee ledovec se n\u00e1hle zastavil a dokonce m\u00edrn\u011b zm\u011bnil sm\u011br.<\/p>\n

Zd\u00e1 se, \u017ee lo\u010f B-15A mo\u017en\u00e1 uv\u00edzla na dn\u011b m\u011blk\u00e9ho mo\u0159e. Umo\u017en\u00ed j\u00ed vliv v\u011btru, p\u0159\u00edlivu a odlivu a t\u00e1n\u00ed dna nakonec znovu vyplout na hladinu?<\/p>\n
