As an ‘El Niño’ climate event heats up in the Pacific, the spotlight is on how we can prepare for the weather and climate shifts that may be in store. The El Niño-Southern Oscillation (ENSO) is a kind of pendulum in the global climate system, swinging back and forth on a 2-7 year cycle, bringing drought to some areas […]
For years, people have been pointing to El Niño as the culprit behind floods, droughts, famines, economic failures, and record-breaking global heat. Can a single climate phenomenon really cause all these events? Is the world just a step away from disaster when El Niño conditions develop? What exactly is this important climate phenomenon and why […]
By Ben Orlove and Ángel Muñoz A new study examines the degree to which decision makers working in key sectors–agriculture, water and health–have been able to make successful use of forecasts of El Niño and La Niña.
