Un'enorme e antichissima piattaforma di ghiaccio dell'Antartide, chiamata Larsen B, potrebbe scomparire entro il 2020.
L'allarme arriva dai ricercatori della Nasa, secondo cui questo tavolato di ghiaccio, che si estende per 1'600 km quadrati e ha uno spessore massimo di 500 metri, si sta rapidamente indebolendo e rischia di disintegrarsi entro la fine del decennio, con conseguenze rilevanti sull'innalzamento del livello del mare.
Un altro scorcio del Larsen B
"Anche se è scientificamente affascinante avere un posto in prima fila per assistere alla disgregazione e alla scomparsa della piattaforma, – dichiarano i ricercatori – è una brutta notizia per il nostro Pianeta".
