Od momentu wystrzelenia w kwietniu 2010 roku satelita CryoSat nale\u017c\u0105cy do ESA kr\u0105\u017cy nad biegunem p\u00f3\u0142nocnym i po\u0142udniowym naszej planety. Jego zadaniem jest obserwowanie zmian grubo\u015bci pokrywy lodowej w tych regionach.<\/p>\n

Po trzech latach obserwacji satelita CryoSat potwierdzi\u0142, \u017ce obj\u0119to\u015b\u0107 lodu arktycznego (Biegun P\u00f3\u0142nocny) maleje. CryoSat wykaza\u0142 r\u00f3wnie\u017c, \u017ce pokrywa lodowa Antarktydy Zachodniej (Biegun Po\u0142udniowy) traci co roku ponad 150 kilometr\u00f3w sze\u015bciennych lodu. Odpowiada to bryle lodu o szeroko\u015bci 1 km, g\u0142\u0119boko\u015bci 1 km i d\u0142ugo\u015bci 150 km!<\/p>\n<\/div>\n

Ogromne pokrywy lodowe, kt\u00f3re pokrywaj\u0105 regiony polarne Ziemi, nie s\u0105 trwa\u0142e. Powi\u0119kszaj\u0105 si\u0119 one w ch\u0142odniejszych okresach, znanych jako epoki lodowcowe, a kurcz\u0105 si\u0119, gdy wzrastaj\u0105 temperatury lub zmieniaj\u0105 si\u0119 lokalne warunki. Nawet pokrywa lodowa Antarktydy, kt\u00f3rej grubo\u015b\u0107 wynosi prawie 3 km, mo\u017ce ulec zmianom.<\/p>\n

Roczna zmiana grubo\u015bci pokrywy lodowej<\/figcaption><\/figure>\n

W Zachodniej Antarktydzie obserwuje si\u0119 obecnie gwa\u0142towny spadek pokrywy lodowej. Dane z satelity CryoSat wskazuj\u0105, \u017ce zjawisko to wyst\u0119puje g\u0142\u00f3wnie w lodowcach, kt\u00f3re wp\u0142ywaj\u0105 do Morza Amundsena. Tempo przerzedzania si\u0119 lodu osi\u0105ga poziom 4\u20138 m rocznie w miejscach, gdzie lodowce Pine Island, Thwaites i Smith opuszczaj\u0105 l\u0105d i zaczynaj\u0105 unosi\u0107 si\u0119 na powierzchni oceanu.<\/p>\n

Uwa\u017cano, \u017ce topnienie lodowc\u00f3w w Zachodniej Antarktydzie spowodowa\u0142o globalny wzrost poziomu morza o 0,28 mm rocznie w latach 2005\u20132010. Jednak najnowsze wyniki bada\u0144 satelity CryoSat wskazuj\u0105, \u017ce wp\u0142yw tego regionu na wzrost poziomu morza jest jeszcze wi\u0119kszy! Mo\u017ce to wynika\u0107 albo z tego, \u017ce l\u00f3d topnieje szybciej, ni\u017c wcze\u015bniej s\u0105dzili naukowcy, albo z tego, \u017ce satelita CryoSat dostarcza dok\u0142adniejszych danych ni\u017c inne satelity!<\/p>","protected":false},"excerpt":{"rendered":"
