De f\u00f8rste ti \u00e5rene av dette \u00e5rhundret var det varmeste ti\u00e5ret som noensinne er registrert. Dette vil trolig f\u00f8re til store endringer i klimaet i Europa. Men hva med polkapperne? Smelter isen? Og hvis ja, hvilken innvirkning vil dette ha p\u00e5 det globale klimaet og havniv\u00e5et?<\/p>\n<\/div>\n<p>En europeisk satellitt gir n\u00e5 noen av svarene. Cryosat, som ble skutt opp 8. april 2010, flyr over polene i en h\u00f8yde p\u00e5 720 km.<\/p>\n<p>Ved hjelp av et toppmoderne radarinstrument m\u00e5ler Cryosat sm\u00e5 endringer i istykkelsen ved \u00e5 sende ut radiosignaler som reflekteres fra overflaten og fange opp ekkoene. Hvis ekkoene kommer tilbake raskere, m\u00e5 isoverflaten v\u00e6re h\u00f8yere.<\/p>\n<p>Cryosat kan registrere endringer p\u00e5 under 2 cm per \u00e5r i h\u00f8yden p\u00e5 isen som flyter p\u00e5 Polhavet. Over de enorme ismassene p\u00e5 det antarktiske kontinentet kan den m\u00e5le \u00e5rlige endringer p\u00e5 under 2 mm.<\/p>\n<p>Disse resultatene hjelper forskere med \u00e5 finne ut om isen i Arktis brytes opp og smelter. De viser ogs\u00e5 om isdekkene som dekker landmassene i Antarktis og havomr\u00e5dene rundt, krymper eller vokser. Dette er viktig fordi havniv\u00e5et kan stige med mange meter hvis isdekkene smelter. Mange lavtliggende byer og land kan da bli oversv\u00f8mmet.<\/p>\n<p>CryoSat er den tredje Earth Explorer-oppdraget som skal skytes opp innenfor rammen av ESAs \u00abLiving Planet\u00bb-program (etter GOCE, ESAs tyngdekraftsoppdrag, og SMOS, ESAs vannoppdrag).<\/p>","protected":false},"excerpt":{"rendered":"<p>Most scientists agree that our planet is getting warmer.
