2026 El Niño Arrival May Impact Global Fisheries

   The Climate Prediction Center of the U.S. National Weather Service (part of NOAA) recently released an analysis indicating a high probability that the current El Niño-a phenomenon driving global climate anomalies-will reach an intensity unprecedented in recorded history. Sea surface temperatures in the central and eastern equatorial Pacific are steadily rising and are expected to peak around November or December; there is currently an 81% chance that this will develop into a "super" El Niño event. Key characteristics of this event include rapid development, high intensity, and significant climatic impact.

   Researchers are currently revisiting the events of 2015 and 2016, when a Pacific heatwave coincided with a strong El Niño, throwing some of the West Coast's most important commercial fishing fleets into turmoil. Malin Pinsky, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, stated: "We could be facing a recurrence of that situation, or perhaps something even worse. I believe the next El Niño is likely to break global temperature records; this is deeply concerning and will have a massive impact on marine fisheries."

   El Niño events are identified by monitoring sea surface temperatures within a specific rectangular region of the Pacific Ocean. The latest forecasts suggest that this year's warming will exceed the magnitude seen during the most severe El Niño events in modern history-specifically those of 1982–83, 1997–98, and 2015–16. Sea surface temperatures in parts of the Pacific are 2 degrees Celsius above normal, while temperatures in the central ocean are 1.4 degrees Celsius higher. As the waters warm, local marine flora and fauna are responding in various ways: some species are dying off, others are failing to reproduce, some are migrating northward, and others are moving into deeper waters. Additionally, some organisms are falling ill due to the rising temperatures or becoming more susceptible to pathogens.
