The extra amount that disappeared last fall was equivalent to this much. It comes back in the winter, but not as permanent ice, as thin ice -- vulnerable. The amount remaining could be completely gone in summer in as little as five years.
Tot el territori que va desaparèixer la tardor passada tenia aquestes dimensions. Torna a formar-se a l'hivern, però no com un gel permanent, sinó com un gel prim. Vulnerable. La quantitat restant podria desaparèixer completament a l'estiu en només cinc anys.
