Ve\u010dina znanstvenikov se strinja, da se na\u0161 planet segreva. Prvih 10 let tega stoletja je bilo najtoplej\u0161e desetletje v zgodovini meritev. To bo verjetno povzro\u010dilo pomembne spremembe v podnebju Evrope. Kako pa je s polarnimi ledenimi pokrovi? Ali se led topi? \u010ce je tako, kak\u0161en vpliv bo to imelo na globalno podnebje in vi\u0161ino morske gladine?<\/p>\n<\/div>\n

Evropski satelit zdaj prina\u0161a nekatere odgovore. Cryosat, ki je bil izstreljen 8. aprila 2010, kro\u017ei nad poloma na vi\u0161ini 720 km.<\/p>\n

S pomo\u010djo najsodobnej\u0161ega radarskega instrumenta Cryosat meri najmanj\u0161e spremembe debeline ledu tako, da radijske signale odbija od povr\u0161ine in zajema odmeve. \u010ce se odmevi vrnejo hitreje, mora biti ledena povr\u0161ina vi\u0161ja.<\/p>\n

Cryosat lahko zazna spremembe vi\u0161ine ledu, ki plava na Arkti\u010dnem oceanu, manj\u0161e od 2 cm na leto. Nad ogromnimi ledenimi pokrovi na celini Antarktike lahko meri letne spremembe, manj\u0161e od 2 mm.<\/p>\n

Ti rezultati znanstvenikom pomagajo ugotoviti, ali se arkti\u010dni morski led drobi in topi. Prav tako ka\u017eejo, ali se ledeni pokrovi, ki prekrivajo kopenski del Antarktike in okoli\u0161ko morje, kr\u010dijo ali \u0161irijo. To je pomembno, saj bi se lahko morska gladina dvignila za ve\u010d metrov, \u010de bi se ledeni pokrovi stopili. Takrat bi lahko poplavilo \u0161tevilna nizko le\u017ee\u010da mesta in dr\u017eave.<\/p>\n

CryoSat je tretja misija v okviru programa \u00bbLiving Planet\u00ab Evropske vesoljske agencije (ESA), ki bo izstreljena (po misijah GOCE, ki se ukvarja z merjenjem gravitacije, in SMOS, ki se ukvarja z merjenjem vode).<\/p>","protected":false},"excerpt":{"rendered":"
