EL Niño has officially arrived, US officials at the National Oceanic and Atmospheric Administration (Noaa) said on Thursday, and scientists predict it could be the strongest of the century.

Forecasters had previously anticipated that a phenomenon known as a super “El Niño” would emerge this summer – supercharging extreme weather events and pushing global temperatures to record heights.
