Wi\u0119kszo\u015b\u0107 naukowc\u00f3w zgadza si\u0119, \u017ce nasza planeta si\u0119 ociepla. Pierwsze dziesi\u0119\u0107 lat tego stulecia by\u0142o najcieplejsz\u0105 dekad\u0105 w historii pomiar\u00f3w. Prawdopodobnie spowoduje to istotne zmiany w klimacie Europy. A co z polarnymi czapami lodowymi? Czy l\u00f3d topnieje? Je\u015bli tak, to jaki wp\u0142yw b\u0119dzie to mia\u0142o na globalny klimat i poziom morza?<\/p>\n<\/div>\n

Odpowiedzi na niekt\u00f3re z tych pyta\u0144 dostarcza obecnie europejski satelita. Cryosat, wystrzelony 8 kwietnia 2010 r., kr\u0105\u017cy nad biegunami na wysoko\u015bci 720 km.<\/p>\n

Wykorzystuj\u0105c najnowocze\u015bniejszy radar, satelita Cryosat mierzy najmniejsze zmiany grubo\u015bci lodu, wysy\u0142aj\u0105c sygna\u0142y radiowe w kierunku powierzchni i odbieraj\u0105c ich echa. Je\u015bli echa docieraj\u0105 z powrotem szybciej, oznacza to, \u017ce powierzchnia lodu jest wy\u017csza.<\/p>\n

Satelita Cryosat jest w stanie wykrywa\u0107 zmiany wysoko\u015bci lodu unosz\u0105cego si\u0119 na Oceanie Arktycznym wynosz\u0105ce mniej ni\u017c 2 cm rocznie. Nad ogromnymi pokrywami lodowymi na kontynencie Antarktydy mo\u017ce mierzy\u0107 roczne zmiany wynosz\u0105ce mniej ni\u017c 2 mm.<\/p>\n

Wyniki te pomagaj\u0105 naukowcom ustali\u0107, czy l\u00f3d morski w Arktyce ulega rozpadowi i topnieniu. Pokazuj\u0105 one r\u00f3wnie\u017c, czy pokrywy lodowe pokrywaj\u0105ce l\u0105d Antarktydy i otaczaj\u0105ce j\u0105 morze kurcz\u0105 si\u0119, czy te\u017c powi\u0119kszaj\u0105. Jest to wa\u017cne, poniewa\u017c w przypadku stopnienia tych pokryw lodowych poziom morza mo\u017ce podnie\u015b\u0107 si\u0119 o wiele metr\u00f3w. W\u00f3wczas wiele nisko po\u0142o\u017conych miast i kraj\u00f3w mog\u0142oby zosta\u0107 zalanych.<\/p>\n

CryoSat to trzecia misja z serii Earth Explorer, kt\u00f3ra zostanie wystrzelona w ramach programu ESA \u201eLiving Planet\u201d (po misji GOCE \u2013 misji grawitacyjnej ESA \u2013 oraz misji SMOS \u2013 misji wodnej ESA).<\/p>","protected":false},"excerpt":{"rendered":"
