Experts believe that the phenomenon of warming waters in the tropical Pacific Ocean is likely to have a strong influence on the temperature of the atmosphere. For three years, it was La Niña that prevailed and restricted heat input from the ocean. A strong El Niño spell can exacerbate the situation to the point that the average temperature in the next five years exceeds the average temperature of the previous five.
