To se morda sli\u0161i kot dobra novica \u2013 vsi imamo radi, ko je zunaj toplo \u2013, a \u017eal je to znak, da se na\u0161e podnebje spreminja. Sateliti, ki kro\u017eijo okoli Zemlje, nam pomagajo spremljati te spremembe in ugotoviti, kaj to\u010dno jih povzro\u010da.<\/p>\n<\/div>\n<p>Podnebne spremembe so velik problem za ljudi na Zemlji. Na primer, vi\u0161je temperature povzro\u010dajo taljenje ledu v Arktiki, zaradi \u010desar se gladina oceanov dviga za pribli\u017eno 3 mm na leto. To se morda ne zdi veliko, a se kmalu se\u0161teje in bi lahko poplavilo obmorska mesta ter \u0161tevilne otoke.<\/p>\n<\/p>\n<p>Dvigovanje morske gladine je nevarna posledica podnebnih sprememb, zato se s pomo\u010djo satelitov izdelujejo zemljevidi vodostajev po vsem na\u0161em planetu. Sateliti pomagajo tudi pri ugotavljanju, od kod izvira dodatna voda, ki povzro\u010da dvig. Glavni vzrok sta taljenje ledenikov in morskega ledu. Poleg tega se voda v na\u0161ih morjih raz\u0161iri, ko se segreje, kar dodatno prispeva k dvigu.<\/p>\n<p>Opazovanje Zemlje iz vesolja pa ni povezano le z vi\u0161ino morske gladine. Sateliti se uporabljajo za spremljanje toplogrednih plinov, ravni ozona, vla\u017enosti tal in \u0161e mnogo ve\u010d! Zbiranje velikih koli\u010din podatkov je prvi korak k kakovostni znanosti in najbolj\u0161i na\u010din, da sprejemamo premi\u0161ljene odlo\u010ditve v zvezi s podnebnimi spremembami.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3872\" data-credit=\"ESA\u2013M.

Znanstveniki, ki prou\u010dujejo Zemljo, potrebujejo podatke, ki zajemajo dalj\u0161e \u010dasovno obdobje \u2013 v idealnem primeru ve\u010d kot 30 let! \u2013, da bi lahko preverili, ali se spremembe dejansko dogajajo. Sateliti pa niso zasnovani za tako dolgo delovanje v vesolju. Tehnologija se nenehno izbolj\u0161uje, zato se gradijo in izstreljujejo novi sateliti, ki nadome\u0161\u010dajo starej\u0161e, kar lahko povzro\u010di nekatere vrzeli v na\u0161em spremljanju Zemlje.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2102\" data-credit=\"ESA\/P.
