Wbrew swojej nazwie Grenlandia jest prawie w ca\u0142o\u015bci pokryta ogromn\u0105 pokryw\u0105 lodow\u0105. Dane z kilku satelit\u00f3w ESA wskazuj\u0105 jednak, \u017ce ta bia\u0142a pokrywa topnieje szybciej ni\u017c oczekiwano.<\/p>\n<\/div>\n

Najnowsze badania lodowc\u00f3w Grenlandii opieraj\u0105 si\u0119 na danych zebranych przez cztery satelity kr\u0105\u017c\u0105ce wok\u00f3\u0142 Ziemi w latach 1996\u20132005. Europejskie satelity teledetekcyjne ERS-1 i ERS-2 nale\u017c\u0105ce do ESA, satelita Envisat nale\u017c\u0105cy do ESA oraz kanadyjski satelita Radarsat-1 s\u0105 wyposa\u017cone w instrumenty radarowe, kt\u00f3re mog\u0105 obserwowa\u0107 powierzchni\u0119 zar\u00f3wno w dzie\u0144, jak i w nocy, nawet przy g\u0119stej pokrywie chmur.<\/p>\n

W szczeg\u00f3lno\u015bci Eric Rignot z Laboratorium Nap\u0119d\u00f3w Odrzutowych NASA oraz naukowiec z Uniwersytetu w Kansas, Pannir Kanagaratnam, byli zainteresowani pomiarem zmian wysoko\u015bci pokrywy lodowej Grenlandii.<\/p>\n

Analizuj\u0105c dane satelitarne, naukowcy odkryli, \u017ce lodowce w po\u0142udniowej i \u015brodkowej Grenlandii p\u0142yn\u0105 szybciej w kierunku morza. Wraz z ociepleniem klimatu ilo\u015b\u0107 lodu, kt\u00f3r\u0105 wprowadzaj\u0105 one do Oceanu Atlantyckiego, podwoi\u0142a si\u0119 w ci\u0105gu ostatnich 10 lat. Naukowcy obliczyli, \u017ce Grenlandia przyczynia si\u0119 w wysoko\u015bci oko\u0142o 0,5 mm rocznie do globalnego wzrostu poziomu morza wynosz\u0105cego oko\u0142o 2,5 mm rocznie.<\/p>\n

Przysz\u0142e badania z wykorzystaniem satelit\u00f3w takich jak Envisat i ERS dostarcz\u0105 istotnych informacji na temat d\u0142ugoterminowych zmian pokrywy lodowej i poziomu morza.<\/p>\n

Grenlandia jest najwi\u0119ksz\u0105 wysp\u0105 na \u015bwiecie. Jej pokrywa lodowa rozci\u0105ga si\u0119 na powierzchni prawie 2 milion\u00f3w kilometr\u00f3w kwadratowych, a jej \u015brednia grubo\u015b\u0107 wynosi 2,3 km. Gdyby ca\u0142y l\u00f3d stopnia\u0142, globalny poziom morza wzr\u00f3s\u0142by nawet o siedem metr\u00f3w.<\/p>","protected":false},"excerpt":{"rendered":"

Despite its name, Greenland is almost entirely covered by a huge sheet of ice. However, data from several ESA satellites suggest that this white blanket is melting faster than expected.
