EL NIÑO - A GLOBAL PHENOMENON
Created for The International Council for Science.
For years, the El Niño Southern Oscillation (ENSO) was understood as a regional phenomenon that mainly affected ocean temperatures and precipitation. But in recent decades, scientists have discovered diverse and far-reaching effects of ENSO on everything from mudslides in Africa to the military history of Europe. El Niño causes many of Earth's most drastic variations in weather, temperature, and rainfall--and its worldwide consequences illustrate how deeply interconnected our planet's climate really is.
