Un'inattesa tempesta di vento caldo sta per abbattersi sul Polo Nord. L'inverno quest'anno è insolitamente mite anche a quelle latitudini. Il responsabile è sempre lo stesso: il cambiamento climatico.
In questi giorni si sta avvicinando dall'Islanda il ciclone Frank, con venti oltre i 130 km/h. L'uragano di categoria 1 sposterà una massa d'aria calda che porterà le temperature fino a 40 gradi sopra la media stagionale (che si attesta solitamente attorno ai 40 gradi sotto lo zero).
Insomma al Polo Nord fa caldo, troppo caldo, e i forti venti attesi non faranno altro che peggiorare il già compromesso ecosistema della regione artica.
