Mumakore 600 apfuura yava aona hafu-gumi chinokosha kwetembiricha, izvo zvakananga kukanganisa nyika yose. Munguva nokufamba ekunze yakadaro inogona kuteverwa cataclysms yose kuti aigona kukuvadza zvose zvipenyu zvose panyika. Zvinokosha kucherechedza kuti okunze kweArctic zvakunoita kumhanya vachishandisa kutenderera nyika mukuru mumhepo riparadzirwe. Masayendisiti akaverenga kuti chakakomba Meteorological kusvetuka ari glacial mapazi ikaitika muna 2030. Kunyange usingashandi kuchabatsira rinokosha nokuda nyika. Chokwadi kuti tembiricha kuverengwa iri kweArctic vari achifumira zvishoma nezvishoma gore rimwe nerimwe. Uye simba yokuchinja remakore rapfuura yakawedzera 2 nguva.
