Can We Blame El Niño for Wild Weather?
ESU601  Can We Blame El Niño for These Events?

People have noticed that when the Pacific Ocean is unusually warm near the beginning of the year, certain things are more likely to happen. Peruvian fishing boat crews know it's probably going to be a bad year for catching anchovies. Seventeen million seabirds on Kiritimati (Christmas) Island in the mid-Pacific may abandon their nests. Heavy rainfall may strike the normally arid coasts of Ecuador and Peru. Parts of Africa, Australia, and the central United States may suffer droughts. These events are linked to a Pacific Ocean phenomenon known as the El Niño Southern Oscillation (ENSO).

How can such widespread phenomena in different parts of the globe be connected to the same event?
