La temperatura in Antartide ha oltrepassato per la prima volta la soglia dei 20 gradi Celsius. Lo ha annunciato il ricercatore brasiliano Carlos Schaefer, che ha registrato il dato di 20,75 gradi nella stazione di monitoraggio attiva sulla Seymour Island, nella regione del continente più vicina al Sudamerica.
Il ricercatore ha precisato che il rilevamento "non fa tendenza dal punto di vista del cambiamento climatico, dal momento che si tratta di un caso isolato". Tuttavia, il fatto che sul continente dei ghiacci sia stata registrata una temperatura così mite non potrà che alimentare ulteriormente il dibattito sul surriscaldamento globale.
