"La Niña", fenomeno climatico che consiste in un raffreddamento delle acque del Pacifico, potrebbe verificarsi nei prossimi mesi. Lo hanno riferito i ricercatori dell’Agenzia federale degli Stati Uniti per la meteorologia (NOAA), secondo cui vi è una probabilità del 50% che si possa manifestare in estate, e dell’80% nel prossimo autunno, o comunque entro la fine del 2016.
Il 2015, invece, è stato caratterizzato dal fenomeno opposto, chiamato "El Niño", che è stato tra i tre più intensi degli ultimi 50 anni e che sta gradualmente diminuendo.
Gli scienziati del Bureau of Meteorology dell’Australia hanno confermato l’andamento de "El Niño", rimanendo però più cauti sulla possibilità che nell'anno corrente si possa verificare l’evento climatico inverso: stando ai modelli climatici internazionali, infatti, è più probabile che ci sia un anno neutro.
