PARIS, France (AFP)—The US National Oceanic and Atmospheric Administration announced Thursday the return of El Nino: the warm phase of a natural climate cycle linked to higher global temperatures and wild weather.
The seesawing shift in ocean temperatures and winds forms across the tropical Pacific Ocean but can influence drought, floods, and other extremes thousands of miles away.
Scientists caution that every El Nino is different and strong events like that forecast this year do not guarantee certain impacts — but tilt the odds in their favour.
