Resumen de Devastating El Niños to double this century
Extreme El Nino events, that can kill tens of thousands of people, will be twice as common this century because of climate change. The finding adds to the evidence that global warming will cause ever more extreme weather. The El Nino Southern Oscillation (ENSO) is one of the most powerful phenomena controlling global weather. An El Nino happens when warm water spreads across the surface of the Pacific, pushing rainfall to the east and causing floods in the Americas and drought in Australia. An El Nino can also bring flooding and drought to parts of Africa because of knock-on effects in the Indian Ocean. El Ninos alternate with La Ninas, which have the opposite effects.
