Oko\u0142o 20 000 lat temu znaczna cz\u0119\u015b\u0107 Europy, Azji, Ameryki P\u00f3\u0142nocnej i Po\u0142udniowej by\u0142a pokryta ogromnymi pokrywami lodowymi, z kt\u00f3rych ka\u017cda mia\u0142a grubo\u015b\u0107 wielu kilometr\u00f3w. Od tamtej pory l\u00f3d stopniowo topnia\u0142, a pokrywy lodowe cofa\u0142y si\u0119. Obecnie jedyne pokrywy lodowe na l\u0105dach Ziemi znajduj\u0105 si\u0119 na Antarktydzie i Grenlandii. L\u00f3d wyst\u0119puje r\u00f3wnie\u017c w postaci lodowc\u00f3w w regionach g\u00f3rskich oraz jako p\u0142ywaj\u0105ce kry lodowe na Oceanie Arktycznym i wok\u00f3\u0142 Antarktydy.<\/p>\n<\/div>\n

Na pierwszy rzut oka te odleg\u0142e pozosta\u0142o\u015bci po ostatniej epoce lodowcowej wydaj\u0105 si\u0119 dzi\u015b dla wi\u0119kszo\u015bci z nas ma\u0142o istotne. Jednak nic nie mo\u017ce by\u0107 dalsze od prawdy. Wielu naukowc\u00f3w uwa\u017ca, \u017ce nasza planeta ociepla si\u0119 w wyniku emisji gaz\u00f3w cieplarnianych, kt\u00f3re uwalniamy do atmosfery. Je\u015bli planeta si\u0119 ociepli, pokrywy lodowe zaczn\u0105 topnie\u0107, powoduj\u0105c podniesienie si\u0119 poziomu morza \u2013 by\u0107 mo\u017ce nawet o kilka metr\u00f3w \u2013 do ko\u0144ca tego stulecia. Taki wzrost poziomu morza spowodowa\u0142by rozleg\u0142e powodzie na nisko po\u0142o\u017conych obszarach przybrze\u017cnych i zagrozi\u0142by wielu du\u017cym miastom.<\/p>\n

Obserwacje z kosmosu wskazuj\u0105, \u017ce niekt\u00f3re cz\u0119\u015bci g\u0142\u00f3wnych pokrywy lodowych zaczynaj\u0105 topnie\u0107 w szybszym tempie. Tymczasem najnowsze zdj\u0119cia satelitarne wykaza\u0142y r\u00f3wnie\u017c, \u017ce podczas arktycznego lata topniej\u0105 niezwykle rozleg\u0142e obszary lodu morskiego. Chocia\u017c topnienie lodu p\u0142ywaj\u0105cego nie wp\u0142ynie na poziom morza, nast\u0105pi\u0105 inne istotne zmiany \u015brodowiskowe. Na przyk\u0142ad pokrywy lodowe dzia\u0142aj\u0105 jak lustro, odbijaj\u0105c promienie s\u0142oneczne i ch\u0142odz\u0105c Ziemi\u0119. Je\u015bli l\u00f3d zniknie, Ziemia prawdopodobnie si\u0119 ociepli i mog\u0105 nast\u0105pi\u0107 powa\u017cne zmiany klimatyczne. Mo\u017ce to r\u00f3wnie\u017c mie\u0107 katastrofalne skutki dla dzikiej przyrody zamieszkuj\u0105cej regiony polarne.<\/p>","protected":false},"excerpt":{"rendered":"
