Understanding the Enigma of El Niño El Niño is a fascinating climate phenomenon that impacts weather and ecosystems worldwide ...

La Niña is part of a natural climate dynamic, along with the better-known El Niño, called El Niño–Southern Oscillation (ENSO). La Niña is ENSO’s cool phase, while El Niño is its warm phase.
