Vaatamata oma nimele on Gr\u00f6\u00f6nimaa peaaegu t\u00e4ielikult kaetud tohutu j\u00e4\u00e4kilbiga. Mitmete ESA satelliitide andmed viitavad aga sellele, et see valge kattekiht sulab oodatust kiiremini.<\/p>\n<\/div>\n

Viimane uuring Gr\u00f6\u00f6nimaa liustike kohta p\u00f5hineb andmetel, mille kogusid neli Maa orbiidil tiirlevat satelliiti aastatel 1996\u20132005. ESA Euroopa kaugseire satelliidid ERS-1 ja ERS-2, ESA satelliit Envisat ning Kanada satelliit Radarsat-1 on k\u00f5ik varustatud radariseadmetega, mis suudavad j\u00e4lgida maapinda nii p\u00e4eval kui \u00f6\u00f6sel, isegi tiheda pilvkatte korral.<\/p>\n

Eelk\u00f5ige olid NASA Jet Propulsion Laboratory teadlane Eric Rignot ja Kansase \u00dclikooli teadlane Pannir Kanagaratnam huvitatud Gr\u00f6\u00f6nimaa j\u00e4\u00e4katte k\u00f5rguse muutuste m\u00f5\u00f5tmisest.<\/p>\n

Satelliidiandmeid uurides selgus teadlastele, et L\u00f5una- ja Kesk-Gr\u00f6\u00f6nimaa liustikud liiguvad mere poole \u00fcha kiiremini. Kliima soojenemise t\u00f5ttu on nende poolt Atlandi ookeani voolav j\u00e4\u00e4kogus viimase 10 aasta jooksul kahekordistunud. Teadlaste arvutuste kohaselt panustab Gr\u00f6\u00f6nimaa umbes 0,5 mm aastas \u00fclemaailmsesse merepinna t\u00f5usu, mis on umbes 2,5 mm aastas.<\/p>\n

Tulevased uuringud, milles kasutatakse selliseid satelliite nagu Envisat ja ERS, annavad olulist teavet selle kohta, kuidas j\u00e4\u00e4katte ja merepinna tase pikas perspektiivis muutuvad.<\/p>\n

Gr\u00f6\u00f6nimaa on maailma suurim saar. Selle j\u00e4\u00e4kilp katab peaaegu 2 miljonit ruutkilomeetrit ja selle keskmine paksus on 2,3 km. Kui kogu j\u00e4\u00e4 sulaks, t\u00f5useks \u00fclemaailmne merepinna tase kuni seitsme meetri v\u00f5rra.<\/p>","protected":false},"excerpt":{"rendered":"
