La California è nota per le sabbie dorate e le onde infinite, ma gran parte del famoso litorale dello stato sulla costa ovest americana potrebbe scomparire entro la fine del secolo.
Lo rivela un nuovo studio dell'US Geological Survey (USGS) secondo il quale tra il 25% e il 70% delle spiagge della California potrebbe essere spazzato via lasciando un paesaggio di scogliere e dirupi a picco sul mare.
Lo studio ha utilizzato le immagini satellitari raccolti negli ultimi vent'anni per esaminare la costa californiana lunga quasi 2'000 chilometri combinandole con modelli di innalzamento del livello del mare causato dalla crisi climatica, per stimare la forma e la posizione della costa dello stato entro il 2100. "Le spiagge sono forse la caratteristica più iconica della California e il rischio di perdere quest'identità è concreto", ha scritto Sean Vitousek, il ricercatore che ha guidato l'analisi che ha indicato le zone di Point Arena e Humboldt Bay nel nord della California, Pismo Beach e Morro Bay nel centro, Newport Beach e San Clemente nel sud come più a rischio.
