Earth's climate doesn't operate in isolated regional pockets. What builds up as a temperature anomaly in the tropical Pacific eventually shows up in the Indian monsoon, in southern Africa's water table, in Australia's wheat harvest. El Niño makes that global connectivity visible in the most direct way possible — through droughts, floods, and food shortages distributed across six continents simultaneously. El Niño events are estimated to affect crop yields on at least a quarter of global croplands. The one confirmed for 2026 is shaping up to be one of the strongest on record. NOAA's Climate Prediction Center gives a 63% probability of a very strong event between November 2026 and January 2027 that could rank among the largest in the historical record since 1950 . Ocean currents transfer significant amounts of heat from Earth's equatorial areas toward the poles and play an important role in the climate of coastal regions worldwide. The map below shows the global ...
