@earthsignalofficial: El Niño and La Niña are opposite phases of the same climate cycle, ENSO. El Niño weakens trade winds and shifts warm Pacific water east. La Niña strengthens trade winds, pushing warm water west and increasing cold-water upwelling. These changes can influence rainfall, temperature, drought, flooding, and storms around the world. The impacts vary by region and season. 🌊 NOAA says El Niño is strengthening, with a greater than 90% chance of a very strong event during fall and winter 2026–27. #ElNino #LaNina #ENSO #ClimateScience #EarthSignal
