N\u00e5r man t\u00e6nker p\u00e5 satellitter, t\u00e6nker man m\u00e5ske p\u00e5 rumteleskoper som Hubble. Men mange satellitter er faktisk rettet mod Jorden og hj\u00e6lper os med at f\u00e5 en bedre forst\u00e5else af den verden, vi lever i, og endda med at forbedre vores dagligdag.<\/p>\n<\/div>\n

Der findes vejrsatellitter, der hj\u00e6lper os med at forberede os p\u00e5 en forest\u00e5ende storm eller blot med at huske at tage solcreme p\u00e5 en varm dag. Kommunikationssatellitter holder os forbundet med mennesker over hele verden via telefoner og internettet. Og s\u00e5 er der satellitter som ESA\u2019s Sentinel-1A og CryoSat, der har overv\u00e5get de arktiske iskapper.<\/p>\n

Disse to satellitter har afsl\u00f8ret, at en af iskapperne, der hedder \u2018Austfonna\u2019, er blevet 50 meter tyndere i l\u00f8bet af de sidste to \u00e5r. (Det betyder, at den har mistet en tykkelse svarende til to gange h\u00f8jden p\u00e5 Buckingham Palace!)<\/p>\n

Ishatte er enorme islag, der ligger ved Jordens nord- og sydpol. Ishattene smelter ikke og fryser ikke til igen i takt med \u00e5rstidernes skiften, men de kan vokse og krympe som f\u00f8lge af klima\u00e6ndringer. For eksempel voksede polkapperne betydeligt under istiderne. Men i \u00f8jeblikket krymper polkapperne, sandsynligvis p\u00e5 grund af den globale opvarmning, som mennesket har for\u00e5rsaget.<\/p>\n

Det betyder, at isen er smeltet til vand og l\u00f8bet ud i havene, hvilket har f\u00e5et havniveauet til at stige. Et stigende havniveau betyder flere oversv\u00f8mmelser og mindre land, hvor vi kan bo og dyrke mad! Derfor er unders\u00f8gelser foretaget af jordoverv\u00e5gningssatellitter, som kan hj\u00e6lpe os med at finde ud af, hvorfor iskapperne smelter, og hvordan det vil p\u00e5virke os i fremtiden, s\u00e5 vigtige.<\/p>","protected":false},"excerpt":{"rendered":"
