Bude Santa Claus jednoho dne pot\u0159ebovat kola na sv\u00e9 s\u00e1n\u011b? To je sice je\u0161t\u011b v nedohlednu, ale satelitn\u00ed pozorov\u00e1n\u00ed ukazuj\u00ed, \u017ee mno\u017estv\u00ed sn\u011bhu pokr\u00fdvaj\u00edc\u00ed severn\u00ed polokouli neust\u00e1le kles\u00e1.<\/p>\n<\/div>\n

Nov\u00e1 anal\u00fdza sn\u011bhov\u00e9 pokr\u00fdvky zaznamenan\u00e9 satelity, jako je nap\u0159\u00edklad Envisat agentury ESA, ukazuje, \u017ee v Evrop\u011b a Asii doch\u00e1z\u00ed ka\u017ed\u00fd \u010derven od roku 2008 k rekordn\u011b n\u00edzk\u00fdm hodnot\u00e1m. Krom\u011b toho byly v posledn\u00edch p\u011bti letech t\u0159ikr\u00e1t zaznamen\u00e1ny rekordn\u011b n\u00edzk\u00e9 hodnoty sn\u011bhov\u00e9 pokr\u00fdvky b\u011bhem severoamerick\u00e9ho l\u00e9ta. To znamen\u00e1, \u017ee rozloha sn\u011bhov\u00e9 pokr\u00fdvky v \u010dervnu je nyn\u00ed nejni\u017e\u0161\u00ed od za\u010d\u00e1tku satelitn\u00edch pozorov\u00e1n\u00ed p\u0159ed p\u0159ibli\u017en\u011b 45 lety.<\/p>\n

Uk\u00e1zalo se, \u017ee sn\u011bhov\u00e1 pokr\u00fdvka v \u010dervnu ub\u00fdv\u00e1 mnohem rychleji, ne\u017e p\u0159edpov\u00eddaly klimatick\u00e9 modely, a sn\u00edh miz\u00ed dokonce rychleji ne\u017e letn\u00ed mo\u0159sk\u00fd led v Arktid\u011b. Satelitn\u00ed data rovn\u011b\u017e ukazuj\u00ed, \u017ee maxim\u00e1ln\u00ed mno\u017estv\u00ed sn\u011bhu na severn\u00ed polokouli se pomalu sni\u017euje, zat\u00edmco jarn\u00ed sn\u00edh \u2013 zejm\u00e9na sm\u011brem k severn\u00edmu p\u00f3lu \u2013 taje d\u0159\u00edve.<\/p>\n

Z\u00e1le\u017e\u00ed na tom, jestli je sn\u011bhu m\u00e9n\u011b a taje rychleji? Zm\u011bny v objemu a rozloze sn\u011bhov\u00e9 pokr\u00fdvky maj\u00ed obrovsk\u00fd vliv na mno\u017estv\u00ed vody v ledovc\u00edch, \u0159ek\u00e1ch a p\u016fd\u011b. Souvis\u00ed tak\u00e9 s dlouhodob\u00fdmi klimatick\u00fdmi zm\u011bnami.<\/p>\n
