Enamik teadlasi on \u00fchel meelel, et meie planeet soojeneb. K\u00e4esoleva sajandi esimesed k\u00fcmme aastat olid ajaloo k\u00f5ige soojemad. See toob t\u00f5en\u00e4oliselt kaasa olulisi muutusi Euroopa kliimas. Aga kuidas on lood polaarj\u00e4\u00e4katetega? Kas j\u00e4\u00e4 sulab? Kui jah, siis millist m\u00f5ju avaldab see globaalsele kliimale ja merepinna tasemele?<\/p>\n<\/div>\n

M\u00f5ned vastused annab n\u00fc\u00fcd Euroopa satelliit. 8. aprillil 2010 orbiidile viidud Cryosat lendab pooluste kohal 720 km k\u00f5rgusel.<\/p>\n

Cryosat m\u00f5\u00f5dab tipptasemel radarseadme abil j\u00e4\u00e4 paksuse v\u00e4ikseid muutusi, suunates raadiosignaale j\u00e4\u00e4pinnale ja v\u00f5ttes vastu neist tagasip\u00f5rkuvaid kajasid. Kui kajad j\u00f5uavad tagasi kiiremini, peab j\u00e4\u00e4pind olema k\u00f5rgem.<\/p>\n

Cryosat suudab tuvastada Arktika ookeanil ujuvate j\u00e4\u00e4kihtide k\u00f5rguses toimuvaid muutusi, mis on v\u00e4iksemad kui 2 cm aastas. Antarktika mandri hiiglaslike j\u00e4\u00e4kilpide kohal suudab see m\u00f5\u00f5ta aastaseid muutusi, mis on v\u00e4iksemad kui 2 mm.<\/p>\n

Need tulemused aitavad teadlastel v\u00e4lja selgitada, kas Arktika merej\u00e4\u00e4 laguneb ja sulab. Samuti n\u00e4itavad need, kas Antarktika maismaad ja seda \u00fcmbritsevat merd katvad j\u00e4\u00e4kilbid kahanevad v\u00f5i suurenevad. See on oluline, sest j\u00e4\u00e4kilpide sulamise korral v\u00f5ib merepinna tase t\u00f5usta mitme meetri v\u00f5rra. Sel juhul v\u00f5ivad paljud madalal asuvad linnad ja riigid \u00fcle ujutatud saada.<\/p>\n

CryoSat on kolmas \u201eEarth Explorer\u201c missioon, mis k\u00e4ivitatakse ESA programmi \u201eLiving Planet\u201c raames (p\u00e4rast GOCE-d, ESA gravitatsioonimissiooni, ja SMOS-i, ESA veemissiooni).<\/p>","protected":false},"excerpt":{"rendered":"
