Ha m\u0171holdakra gondolunk, esz\u00fcnkbe juthatnak olyan \u0171rt\u00e1vcs\u00f6vek, mint a Hubble. Val\u00f3j\u00e1ban azonban sok m\u0171hold a F\u00f6ld fel\u00e9 van ir\u00e1ny\u00edtva, \u00e9s seg\u00edt nek\u00fcnk jobban meg\u00e9rteni a vil\u00e1got, amelyben \u00e9l\u00fcnk, s\u0151t, jav\u00edtani is tudja mindennapi \u00e9let\u00fcnket.<\/p>\n<\/div>\n

Vannak olyan meteorol\u00f3giai m\u0171holdak, amelyek seg\u00edtenek felk\u00e9sz\u00fclni egy k\u00f6zeled\u0151 viharra, vagy egyszer\u0171en csak eml\u00e9keztetnek arra, hogy forr\u00f3 napokon ne felejts\u00fck el a naptejet. A t\u00e1vk\u00f6zl\u00e9si m\u0171holdak pedig telefonon \u00e9s az interneten kereszt\u00fcl biztos\u00edtj\u00e1k a kapcsolatot az emberekkel szerte a vil\u00e1gon. \u00c9s vannak olyan m\u0171holdak is, mint az ESA Sentinel-1A \u00e9s CryoSat m\u0171holdjai, amelyek az \u00c9szaki-sarkvid\u00e9k j\u00e9gsapk\u00e1it figyelik.<\/p>\n

Ezek a k\u00e9t m\u0171hold meg\u00e1llap\u00edtott\u00e1k, hogy az egyik j\u00e9gsapka \u2013 az \u00fagynevezett \u2018Austfonna\u2019 \u2013 az elm\u00falt k\u00e9t \u00e9vben 50 m\u00e9terrel v\u00e9konyodott. (Ez azt jelenti, hogy a Buckingham-palota magass\u00e1g\u00e1nak k\u00e9tszeres\u00e9t vesztette el!)<\/p>\n

A j\u00e9gsapk\u00e1k hatalmas j\u00e9gtakar\u00f3k, amelyek a F\u00f6ld \u00e9szaki \u00e9s d\u00e9li sark\u00e1n helyezkednek el. A j\u00e9gsapk\u00e1k nem olvadnak el \u00e9s nem fagynak vissza \u00e9vszakonk\u00e9nt, de az \u00e9ghajlati v\u00e1ltoz\u00e1sok hat\u00e1s\u00e1ra n\u00f6vekedhetnek \u00e9s zsugorodhatnak. P\u00e9ld\u00e1ul a j\u00e9gkorszakok idej\u00e9n a sarki j\u00e9gsapk\u00e1k sokkal nagyobbak lettek. Jelenleg azonban a sarki j\u00e9gsapk\u00e1k zsugorodnak, val\u00f3sz\u00edn\u0171leg az ember \u00e1ltal okozott glob\u00e1lis felmeleged\u00e9s miatt.<\/p>\n

Ez azt jelenti, hogy a j\u00e9g v\u00edzr\u00e9 v\u00e1ltozott, \u00e9s az \u00f3ce\u00e1nokba folyt, ami a tengerszint emelked\u00e9s\u00e9t okozta. A tengerszint emelked\u00e9se pedig t\u00f6bb \u00e1rvizet \u00e9s kevesebb sz\u00e1razf\u00f6ldet jelent sz\u00e1munkra, ahol \u00e9lhet\u00fcnk \u00e9s \u00e9lelmet termelhet\u00fcnk! \u00c9ppen ez\u00e9rt olyan fontosak azok a F\u00f6ld-megfigyel\u0151 m\u0171holdak \u00e1ltal v\u00e9gzett kutat\u00e1sok, amelyek seg\u00edts\u00e9g\u00e9vel kider\u00edthetj\u00fck, mi\u00e9rt olvadnak a j\u00e9gsapk\u00e1k, \u00e9s milyen hat\u00e1ssal lesz ez r\u00e1nk a j\u00f6v\u0151ben.<\/p>","protected":false},"excerpt":{"rendered":"
