El Niño Event Forms in Pacific Ocean, Early Forecasts Signal Strong Cycle

An El Niño weather pattern has formed over the Pacific Ocean according to an announcement from the National Oceanic and Atmospheric Administration. Early forecasts indicate a 63% chance that sea surface temperatures will surpass 2.0°C, a level associated with very strong events.

Niño forms every few years when weakening wind patterns leave warmer surface water near the Americas. The pattern typically lasts up to a year and alters rainfall and temperature conditions worldwide. A 2023 paper in Science calculated that two prior strong El Niño events in 1982 and 1997 each produced global income losses exceeding $4 trillion.

Those losses stemmed primarily from damage to agricultural output.

Current forecasts and reported effects Current models project conditions that could match the strength of past intense cycles. A ratings agency analysis published this week stated that poorer countries reliant on agriculture would likely face the largest costs.

The European Commission forecast published this week said several staple crops including wheat, corn, and rice could see price increases. Officials noted that the event coincides with already elevated fuel prices linked to recent Middle East developments.

Shipping routes may also face disruption. A prior strong El Niño reduced Panama Canal transits from 36 ships per day to 24 due to low water levels. The Panama Canal Authority has indicated it expects limited change to current volumes but is preparing operational adjustments for 2027.

Robert Muggah, a political scientist, wrote in a World Economic Forum blog that governments, companies and aid agencies should treat the outlook as an early warning for potential systemic effects on the global economy.
