La cima del Cervino rischia di crollare. L'allarme è stato lanciato venerdì da un meteorologo di MeteoNews, Frédéric Glassey, il quale ha spiegato che lo scioglimento del permafrost potrebbe causare un disastro senza precedenti, a causa dell'ondata di caldo che ha investito anche uno dei simboli della Svizzera.

"La temperatura sulla vetta della montagna, a 4'478 metri, è arrivata al di sopra degli zero gradi centigradi — ha illustrato lo scienziato —. La parte più alta della montagna è costituita dalla 'schistouille', un cumulo di rocce unito dal permafrost, il terreno perennemente ghiacciato", si legge nell'intervista pubblicata sul quotidiano vallesano "Le Nouvelliste".
"Se questo si scongela, le pietre cadranno", conclude Glassey.
