Antarktis har klarat sig relativt v\u00e4l undan fr\u00e5n klimatf\u00f6r\u00e4ndringarna. Men enligt en f\u00e4rsk studie b\u00f6rjar situationen p\u00e5 kontinenten allt mer likna den p\u00e5 Gr\u00f6nland.<\/strong><\/p>\n\n\n\n

Forskarna vid DMI, danska versionen av SMHI, kallar utvecklingen f\u00f6r en \u201dGr\u00f6nlandifiering\u201d, n\u00e4r sm\u00e4ltningen kring s\u00f6dra polen sker allt snabbare och mer is g\u00e5r f\u00f6rlorad till havet.<\/p>\n\n\n\n

J\u00e4mf\u00f6rt med Gr\u00f6nland \u00e4r m\u00e4ngden is p\u00e5 Antarktis enorm. Om isen p\u00e5 Gr\u00f6nland sm\u00e4lter stiger v\u00e4rldshaven sju meter. Om samma sak skedde med Antarktis skulle havsh\u00f6jningen bli 50 meter.<\/p>\n\n\n\n

\u201dAntarktis har l\u00e4nge ansetts vara mer stabilt \u00e4n Arktis. Men i dag har bilden f\u00f6r\u00e4ndrats: havsisen f\u00f6rsvinner, temperaturen stiger \u00e4ven h\u00e4r, isfl\u00f6dena accelererar och sm\u00e4ltvatten tr\u00e4nger in i glaci\u00e4rernas sprickor, vilket g\u00f6r att de glider snabbare mot havet\u201d, s\u00e4ger huvudf\u00f6rfattaren Ruth Mottram i ett pressmeddelande.<\/a><\/p>\n\n\n\n

I studien, som publiceras i Nature Geoscience,<\/a> har forskarna anv\u00e4nt sig av satellitm\u00e4tningar, radar- och laserskanningar liksom bojar, fartygsm\u00e4tningar och klimatmodeller.<\/p>\n\n\n\n

Det kan vara v\u00e4rre f\u00f6r oss h\u00e4r i norr att isen p\u00e5 Antarktis sm\u00e4lter, \u00e4n att den p\u00e5 Gr\u00f6nland g\u00f6r det. N\u00e4r isen i syd sm\u00e4lter f\u00f6rdelas vattnet p\u00e5 ett s\u00e4tt s\u00e5 att det stiger mer p\u00e5 v\u00e5ra breddgrader och vice versa, enligt forskarna.<\/p>\n\n\n\n

\u201dDet \u00e4r f\u00f6r\u00f6dande, eftersom ismassorna i s\u00f6der har en dramatisk potential i form av stigande havsniv\u00e5er f\u00f6r oss i norr\u201d.<\/p>\n\n\n\n
