El Niño, la corrente anomala che può seminare devastazione in molti continenti, è tornato. Dopo 5 anni di pausa si è infatti formata di nuovo sull’Oceano Pacifico e verosimilmente influirà sul clima globale dei prossimi mesi, creando le premesse per un ulteriore record di caldo, ma anche di forti piogge.
La siccità del 1998 in Tailandia
In Cile, Perù e Bolivia sono attese violente alluvioni, in Australia e in Indonesia lunghe siccità, il clima diventerà ancora più secco nell'Africa subsahariana e nel Golfo di Guinea e le correnti aeree di alta quota verranno modificate.
Il fenomeno nell'Oceano Pacifico tra il dicembre del 1997 ed il mese di giugno del 1998
Nel 1998, quando questa corrente uccise migliaia di persone, si arrivò a temperature molto alte mettendo in gioco una quantità di energia che produsse conseguenze devastanti. Ancora non è chiaro però quanto il fenomeno possa interessare il clima dell’Europa.
