Lesz-e egyszer sz\u00fcks\u00e9ge a Mikul\u00e1snak kerekekre a sz\u00e1nj\u00e1hoz? Ez m\u00e9g messze van, de a m\u0171holdas megfigyel\u00e9sek azt mutatj\u00e1k, hogy az \u00c9szaki F\u00e9ltek\u00e9t bor\u00edt\u00f3 h\u00f3 mennyis\u00e9ge folyamatosan cs\u00f6kken.<\/p>\n<\/div>\n

Az olyan m\u0171holdak \u2013 mint p\u00e9ld\u00e1ul az ESA Envisatja \u2013 \u00e1ltal r\u00f6gz\u00edtett h\u00f3takar\u00f3 \u00faj elemz\u00e9se azt mutatja, hogy 2008 \u00f3ta minden j\u00faniusban rekordalacsony \u00e9rt\u00e9keket regisztr\u00e1ltak Eur\u00f3p\u00e1ban \u00e9s \u00c1zsi\u00e1ban. Emellett az elm\u00falt \u00f6t \u00e9vb\u0151l h\u00e1romban rekord alacsony h\u00f3takar\u00f3 volt jellemz\u0151 az \u00e9szak-amerikai ny\u00e1ri id\u0151szakban. Ez azt jelenti, hogy a j\u00faniusban h\u00f3val bor\u00edtott ter\u00fclet jelenleg a legkisebb, ami\u00f3ta a m\u0171holdas megfigyel\u00e9sek k\u00f6r\u00fclbel\u00fcl 45 \u00e9vvel ezel\u0151tt megkezd\u0151dtek.<\/p>\n

Meg\u00e1llap\u00edtott\u00e1k, hogy a j\u00faniusi h\u00f3takar\u00f3 sokkal gyorsabban cs\u00f6kken, mint amit az \u00e9ghajlati modellek j\u00f3soltak, \u00e9s a h\u00f3 m\u00e9g az \u00c9szaki-sarkvid\u00e9ken ny\u00e1ron kialakul\u00f3 tengeri j\u00e9gn\u00e9l is gyorsabban t\u0171nik el. A m\u0171holdas adatok azt is mutatj\u00e1k, hogy az \u00e9szaki f\u00e9ltek\u00e9n a h\u00f3 maxim\u00e1lis mennyis\u00e9ge lassan cs\u00f6kken, m\u00edg a tavaszi h\u00f3 \u2013 k\u00fcl\u00f6n\u00f6sen az \u00c9szaki-sark fel\u00e9 \u2013 egyre kor\u00e1bban olvad el.<\/p>\n

Sz\u00e1m\u00edt-e, ha kevesebb a h\u00f3, \u00e9s gyorsabban olvad el? A h\u00f3t\u00f6meg \u00e9s a h\u00f3takar\u00f3 kiterjed\u00e9s\u00e9nek v\u00e1ltoz\u00e1sai hatalmas hat\u00e1ssal vannak a gleccserekben, a foly\u00f3kban \u00e9s a talajban tal\u00e1lhat\u00f3 v\u00edzmennyis\u00e9gre. Ezenk\u00edv\u00fcl \u00f6sszef\u00fcgg\u00e9sben \u00e1llnak a hossz\u00fa t\u00e1v\u00fa \u00e9ghajlati v\u00e1ltoz\u00e1sokkal is.<\/p>\n

Lehet, hogy a j\u00f6v\u0151ben nem csak a Mikul\u00e1snak kell majd megv\u00e1ltoztatnia az \u00e9letm\u00f3dj\u00e1t\u2026<\/p>","protected":false},"excerpt":{"rendered":"
