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.
Il territorio scomparso l'autunno scorso era di queste dimensioni. Ritorna in inverno, non come ghiaccio perenne, ma come ghiaccio sottile. Vulnerabile. Quel che resta potrebbe scomparire del tutto in estate nel giro di appena 5 anni.
