Kdy\u017e se \u0159ekne \u201esatelity\u201c, mo\u017en\u00e1 se v\u00e1m vybav\u00ed vesm\u00edrn\u00e9 dalekohledy, jako je Hubble. Mnoho satelit\u016f v\u0161ak ve skute\u010dnosti m\u00ed\u0159\u00ed sm\u011brem k Zemi a pom\u00e1h\u00e1 n\u00e1m l\u00e9pe porozum\u011bt sv\u011btu, ve kter\u00e9m \u017eijeme, a dokonce i zlep\u0161ovat n\u00e1\u0161 ka\u017edodenn\u00ed \u017eivot.<\/p>\n<\/div>\n

Existuj\u00ed meteorologick\u00e9 satelity, kter\u00e9 n\u00e1m pom\u00e1haj\u00ed p\u0159ipravit se na bl\u00ed\u017e\u00edc\u00ed se bou\u0159i nebo n\u00e1m prost\u011b p\u0159ipomenou, abychom si v hork\u00e9m dni nezapomn\u011bli vz\u00edt opalovac\u00ed kr\u00e9m.

A pak jsou tu satelity jako Sentinel-1A a CryoSat agentury ESA, kter\u00e9 sleduj\u00ed arktick\u00e9 ledov\u00e9 \u010depice.<\/p>\n

Tyto dv\u011b dru\u017eice zjistily, \u017ee jedna z ledov\u00fdch \u010depic, naz\u00fdvan\u00e1 \u2018Austfonna\u2019, se za posledn\u00ed dva roky zten\u010dila o 50 metr\u016f. (To znamen\u00e1, \u017ee ztratila dvakr\u00e1t tolik na v\u00fd\u0161ce, kolik m\u011b\u0159\u00ed Buckinghamsk\u00fd pal\u00e1c!)<\/p>\n

Ledov\u00e9 \u010depice jsou obrovsk\u00e9 ledov\u00e9 plochy, kter\u00e9 se nach\u00e1zej\u00ed na severn\u00edm a ji\u017en\u00edm p\u00f3lu Zem\u011b. Tyto \u010depice se sez\u00f3nn\u011b nerozt\u00e1vaj\u00ed a znovu nezamrzaj\u00ed, ale mohou se zv\u011bt\u0161ovat a zmen\u0161ovat v d\u016fsledku klimatick\u00fdch zm\u011bn. Nap\u0159\u00edklad b\u011bhem dob ledov\u00fdch se pol\u00e1rn\u00ed ledov\u00e9 \u010depice v\u00fdrazn\u011b zv\u011bt\u0161ily. V sou\u010dasn\u00e9 dob\u011b v\u0161ak pol\u00e1rn\u00ed ledov\u00e9 \u010depice zmen\u0161uj\u00ed svou rozlohu, s nejv\u011bt\u0161\u00ed pravd\u011bpodobnost\u00ed kv\u016fli glob\u00e1ln\u00edmu oteplov\u00e1n\u00ed zp\u016fsoben\u00e9mu lidskou \u010dinnost\u00ed.<\/p>\n

To znamen\u00e1, \u017ee led se prom\u011bnil ve vodu a odt\u00e9k\u00e1 do oce\u00e1n\u016f, co\u017e zp\u016fsobuje vzestup hladiny mo\u0159\u00ed. Vzestup hladiny mo\u0159\u00ed znamen\u00e1 v\u00edce povodn\u00ed a m\u00e9n\u011b p\u016fdy, na kter\u00e9 m\u016f\u017eeme \u017e\u00edt a p\u011bstovat si j\u00eddlo!
