C\u00e2nd te g\u00e2nde\u0219ti la sateli\u021bi, s-ar putea s\u0103-\u021bi vin\u0103 \u00een minte telescoape spa\u021biale precum Hubble. \u00cens\u0103, de fapt, mul\u021bi sateli\u021bi sunt orienta\u021bi spre P\u0103m\u00e2nt, ajut\u00e2ndu-ne s\u0103 \u00een\u021belegem mai bine lumea \u00een care tr\u0103im \u0219i chiar s\u0103 ne \u00eembun\u0103t\u0103\u021bim via\u021ba de zi cu zi.<\/p>\n<\/div>\n

Exist\u0103 sateli\u021bi meteorologici care ne ajut\u0103 s\u0103 ne preg\u0103tim pentru o furtun\u0103 care se apropie sau pur \u0219i simplu s\u0103 nu uit\u0103m s\u0103 ne d\u0103m cu crem\u0103 de protec\u021bie solar\u0103 \u00eentr-o zi torid\u0103. Sateli\u021bii de comunica\u021bii ne men\u021bin \u00een leg\u0103tur\u0103 cu oameni din \u00eentreaga lume prin intermediul telefoanelor \u0219i al internetului. \u0218i mai sunt \u0219i sateli\u021bi precum Sentinel-1A \u0219i CryoSat ai ESA, care monitorizeaz\u0103 calotele de ghea\u021b\u0103 din Arctica.<\/p>\n

Ace\u0219ti doi sateli\u021bi au descoperit c\u0103 una dintre calotele de ghea\u021b\u0103, numit\u0103 \u2018Austfonna\u2019, s-a sub\u021biat cu 50 de metri \u00een ultimii doi ani. (Asta \u00eenseamn\u0103 c\u0103 a pierdut o grosime egal\u0103 cu dublul \u00een\u0103l\u021bimii Palatului Buckingham!)<\/p>\n

Calotele polare sunt imense straturi de ghea\u021b\u0103 situate la polii Nord \u0219i Sud ai P\u0103m\u00e2ntului. Acestea nu se topesc \u0219i nu \u00eenghea\u021b\u0103 din nou \u00een func\u021bie de anotimpuri, dar pot cre\u0219te sau se pot mic\u0219ora ca urmare a schimb\u0103rilor climatice. De exemplu, \u00een timpul erelor glaciare, calotele polare au crescut mult \u00een dimensiuni. \u00cens\u0103, \u00een prezent, calotele polare se mic\u0219oreaz\u0103, cel mai probabil din cauza \u00eenc\u0103lzirii globale provocate de activitatea uman\u0103.<\/p>\n

Asta \u00eenseamn\u0103 c\u0103 ghea\u021ba s-a transformat \u00een ap\u0103 \u0219i s-a scurs \u00een oceane, provoc\u00e2nd cre\u0219terea nivelului m\u0103rii. Cre\u0219terea nivelului m\u0103rii \u00eenseamn\u0103 mai multe inunda\u021bii \u0219i mai pu\u021bin teren pe care s\u0103 tr\u0103im \u0219i s\u0103 cultiv\u0103m alimente! De aceea sunt at\u00e2t de importante studiile realizate cu ajutorul sateli\u021bilor de monitorizare a P\u0103m\u00e2ntului, care ne pot ajuta s\u0103 afl\u0103m de ce se topesc calotele glaciare \u0219i cum ne va afecta acest fenomen \u00een viitor.<\/p>","protected":false},"excerpt":{"rendered":"
