CryoSat a ar\u0103tat, de asemenea, c\u0103 calota glaciar\u0103 din Antarctica de Vest (Polul Sud) pierde peste 150 de kilometri cubi de ghea\u021b\u0103 \u00een fiecare an. Aceasta echivaleaz\u0103 cu o plac\u0103 de ghea\u021b\u0103 de 1 km l\u0103\u021bime, 1 km ad\u00e2ncime \u0219i 150 km lungime!<\/p>\n<\/div>\n<p>Straturile masive de ghea\u021b\u0103 care acoper\u0103 regiunile polare ale P\u0103m\u00e2ntului nu sunt permanente.

Cu toate acestea, noile date furnizate de CryoSat sugereaz\u0103 c\u0103 contribu\u021bia acestei regiuni la cre\u0219terea nivelului m\u0103rii este chiar mai mare!
