Sellest ajast alates on j\u00e4\u00e4 j\u00e4rk-j\u00e4rgult sulanud ja j\u00e4\u00e4kilbid on taandunud. T\u00e4nap\u00e4eval asuvad Maakera maismaadel j\u00e4\u00e4kilbid ainult Antarktikas ja Gr\u00f6\u00f6nimaal.

Kuid midagi ei saaks olla t\u00f5est kaugemal. Paljud teadlased usuvad, et meie planeet soojeneb atmosf\u00e4\u00e4ri paisatavate kasvuhoonegaaside t\u00f5ttu. Kui planeet soojeneb, hakkavad j\u00e4\u00e4kilbid sulama, mille tagaj\u00e4rjel v\u00f5ib merepinna tase t\u00f5usta selle sajandi l\u00f5puks isegi mitme meetri v\u00f5rra.

Samal ajal on hiljutised satelliidipildid n\u00e4idanud, et Arktika suve jooksul on sulanud ebatavaliselt suured merej\u00e4\u00e4alad. Kuigi ujuvj\u00e4\u00e4 sulamine ei m\u00f5juta merepinna taset, toimuvad muud olulised keskkonnamuutused. N\u00e4iteks toimivad j\u00e4\u00e4kilbid peeglina, peegeldades p\u00e4ikesevalgust ja jahutades Maad. Kui j\u00e4\u00e4 kaob, muutub Maa t\u00f5en\u00e4oliselt soojemaks ja v\u00f5ib toimuda suuri kliimamuutusi.
