Kljub svojemu imenu je Grenlandija skoraj v celoti prekrita z ogromno ledeno plo\u0161\u010do. Podatki ve\u010d satelitov agencije ESA pa ka\u017eejo, da se ta bela odeja topi hitreje, kot se je pri\u010dakovalo.<\/p>\n<\/div>\n

Najnovej\u0161a \u0161tudija grenlandskih ledenikov temelji na podatkih, ki so jih med letoma 1996 in 2005 zbrali \u0161tirje sateliti v zemeljski orbiti. Evropski sateliti za daljinsko zaznavanje ERS-1 in ERS-2 agencije ESA, satelit Envisat agencije ESA ter kanadski satelit Radarsat-1 so vsi opremljeni z radarskimi instrumenti, ki lahko opazujejo povr\u0161ino podnevi in pono\u010di, tudi \u010de je nebo gosto obla\u010dno.<\/p>\n

Zlasti sta se Eric Rignot iz Laboratorija za reaktivni pogon (JPL) pri NASA in znanstvenik Pannir Kanagaratnam z Univerze v Kansasu zanimala za merjenje sprememb vi\u0161ine grenlandske ledenega pokrova.<\/p>\n

Z analizo satelitskih podatkov so znanstveniki ugotovili, da se ledeniki v ju\u017eni in osrednji Grenlandiji hitreje pomikajo proti morju. Zaradi segrevanja podnebja se je koli\u010dina ledu, ki jo v zadnjih 10 letih odlagajo v Atlantski ocean, podvojila. Znanstveniki so izra\u010dunali, da Grenlandija prispeva pribli\u017eno 0,5 mm na leto k globalnemu dvigu morske gladine, ki zna\u0161a pribli\u017eno 2,5 mm na leto.<\/p>\n

Prihodnje raziskave s pomo\u010djo satelitov, kot sta Envisat in ERS, bodo prinesle klju\u010dne informacije o dolgoro\u010dnih spremembah ledene odeje in morske gladine.<\/p>\n

Grenlandija je najve\u010dji otok na svetu. Njen ledeni pokrov pokriva skoraj 2 milijona kvadratnih kilometrov in ima povpre\u010dno debelino 2,3 km. \u010ce bi se ves led stopil, bi se svetovna morska gladina dvignila za do sedem metrov.<\/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.
