El Nino Conditions Beginning In The Tropical Pacific

Weather forecasting centers around the world have now declared that an El Niño, the most powerful fluctuation in Earth’s climate system, has begun in the tropical Pacific. El Niño is a warming of the Pacific Ocean as part of a complex cycle linking atmosphere and ocean. An El Niño can raise global temperatures, says the UK’s Met Office. A El Niño event brings a higher risk of more, and more severe, tropical cyclones. Impacts on the biosphere are expected, such as coral bleaching and widespread movements of marine life.
