Why We Call It El Niño and La Niña, Not Warmer Oceans

Every few years, the Pacific Ocean flips between two dramatic moods — one that warms the world, and one that cools it. Scientists call these phases El Niño and La Niña. But many people wonder: why use Spanish names instead of simply saying “warmer ocean” or “colder ocean”? The answer lies in a blend of history, science, and communication. These names describe far more than temperature; they reflect a powerful global rhythm that connects ocean and atmosphere.
