N\u00e4r man t\u00e4nker p\u00e5 satelliter kanske man t\u00e4nker p\u00e5 rymdteleskop som Hubble. Men m\u00e5nga satelliter \u00e4r faktiskt riktade mot jorden och hj\u00e4lper oss att b\u00e4ttre f\u00f6rst\u00e5 den v\u00e4rld vi lever i och till och med f\u00f6rb\u00e4ttra v\u00e5r vardag.<\/p>\n<\/div>\n

Det finns v\u00e4dersatelliter som hj\u00e4lper oss att f\u00f6rbereda oss inf\u00f6r en annalkande storm eller helt enkelt att komma ih\u00e5g att ta med solkr\u00e4m en varm dag. Kommunikationssatelliter h\u00e5ller oss i kontakt med m\u00e4nniskor \u00f6ver hela v\u00e4rlden via telefon och internet. Och s\u00e5 finns det satelliter som ESA:s Sentinel-1A och CryoSat, som har \u00f6vervakat isarna i Arktis.<\/p>\n

Dessa tv\u00e5 satelliter har visat att en av iskapporna, som kallas \u2018Austfonna\u2019, har blivit 50 meter tunnare under de senaste tv\u00e5 \u00e5ren. (Det inneb\u00e4r att den har f\u00f6rlorat en tjocklek som motsvarar dubbla h\u00f6jden p\u00e5 Buckingham Palace!)<\/p>\n

Islockarna \u00e4r enorma ismassor som ligger vid jordens nord- och sydpoler. Islockarna sm\u00e4lter inte och fryser inte igen i takt med \u00e5rstiderna, men de kan v\u00e4xa och krympa p\u00e5 grund av klimatf\u00f6r\u00e4ndringar. Under istiderna v\u00e4xte till exempel polkapparna sig mycket st\u00f6rre. Men just nu krymper polkapparna, troligen p\u00e5 grund av den globala uppv\u00e4rmningen som orsakats av m\u00e4nniskan.<\/p>\n

Det inneb\u00e4r att isen har sm\u00e4lt till vatten och runnit ut i haven, vilket har lett till att havsniv\u00e5n stiger. En stigande havsniv\u00e5 inneb\u00e4r fler \u00f6versv\u00e4mningar och mindre mark d\u00e4r vi kan bo och odla mat! D\u00e4rf\u00f6r \u00e4r studier som utf\u00f6rs med hj\u00e4lp av jord\u00f6vervakningssatelliter \u2013 som kan hj\u00e4lpa oss att ta reda p\u00e5 varf\u00f6r ist\u00e4ckena sm\u00e4lter och hur det kommer att p\u00e5verka oss i framtiden \u2013 s\u00e5 viktiga.<\/p>","protected":false},"excerpt":{"rendered":"
