The Pacific Has Spoken Before, But This Time It Roars

There is a rhythm to the Pacific Ocean that humans have learned to read only imperfectly. Every few years, the trade winds falter, the warm water sloshes eastward, and the consequences ripple outward in ways that touch everything from the price of fish to the air that millions of people breathe. This year, the rhythm has become something closer to a roar.

The 2026 El Niño is shaping up to be the strongest on record, with sea surface temperatures in the central tropical Pacific reaching levels that have broken previous benchmarks . The Japan Meteorological Agency reported that temperatures off Peru exceeded averages by four degrees Celsius in September, the largest deviation since record-keeping began in 1949 . Scientists have reached for superlatives—"super," "monster," "Godzilla," "ultra"—each attempting to capture an event that resists easy description.

Indonesia is burning. From January to September, 1.9 million hectares of land burned across the archipelago, according to satellite imagery analyzed by Nusantara Atlas, a figure thirty-eight percent higher than the comparable period in 2019, the previous worst year on record . Much of what has burned is peatland, a carbon-rich wetland that, once dry, becomes both fuel and greenhouse emission. The resulting haze has choked the region, prompting Singapore to issue ten notices under its Transboundary Haze Pollution Act ordering Indonesian companies to address fires on their land .

The effects are not confined to Southeast Asia. The Peruvian anchoveta fishery has collapsed, with fishers catching less than a quarter of their quota in the first half of the year . The Panama Canal is drying up, and sugar crops are failing in India and Thailand . In Chile, record-breaking rainfall submerged vast areas of Santiago's residential neighborhoods . In California, ecologists are racing to collect reproductive tissue from temperature-sensitive kelp before expected marine heat waves wipe out beds that have not recovered from the 2014-15 event .

What makes this El Niño particularly significant is its timing. It is occurring against a backdrop of rapid global warming, a combination that scientists describe as a preview of the future. "It's going to be a very, very strong event occurring against a backdrop of very rapid global warming," said Christopher Callahan, a climate scientist at Indiana University. "I think we're going to, unfortunately, learn a lot this year" . The Peterson Institute for International Economics has estimated the global economic hit could reach nearly one trillion dollars in direct initial losses, with at least 7.2 trillion over five years unless international institutions act swiftly .

The human dimensions are harder to quantify but no less real. The United Nations estimates more than 347 million children in nearly 100 countries will experience unusually wet or dry conditions between October and December, increasing the risk of extreme floods and droughts . In Peru, a seafood restaurant owner described the cost of fish with a weary precision: "This is over 14 dollars per kilo, or 32 dollars for a fillet. That's too high for ceviche" . In Japan, farmed amberjack operators face feed prices that have doubled because of poor sardine catches off Peru .

There is a strange duality to how scientists speak of this event. They are worried, but also, in a way that only researchers can be, intrigued. "Most of us climate change ecology people are kind of perversely excited about it," said John Bruno, a marine ecologist at the University of North Carolina at Chapel Hill. "It's an experimental treatment that nature is providing to us" . The data collected in the coming months will inform predictions for decades, a silver lining to a very dark cloud.

For now, the El Niño is expected to peak around November or December and persist into autumn 2027 . The fires will continue to burn, the fisheries will continue to struggle, and the weather will continue to rearrange itself in ways that remind us how deeply connected the planet's systems remain. The Pacific has spoken before. This year, it is speaking louder than at any time in living memory.
