Everything we've published on El Niño: articles, news, opinion and video.
In the austral summer the trade winds come at the Great Barrier Reef steadily out of the east, dragging cooler, drier air across the shallows and pulling heat out of the water. Then, in some summers,…
Not whether the planet is warming, but whether the warming itself has sped up: that narrower question has had two confident and opposite answers in the space of two years, from different teams…
A study published Oct. 15, 2026, in Nature Climate Change finds that the thin layers of ocean air that carry radio and radar signals far past the horizon have grown more frequent, stronger and deeper…
World Weather Attribution said Oct. 15, 2026, that human-caused warming made the ocean and air conditions capable of fueling a storm like Hurricane Polo about 23 times likelier than they would have…
New climate simulations find the tropical Pacific does not return to its earlier state after greenhouse gas emissions stop. In runs that continue for centuries past the point of net zero, the region…
The monthly sea surface temperature in the Pacific's Niño 3.4 region, the stretch of ocean used to monitor El Niño, reached an all-time high of 29.70 °C in September 2026, the Copernicus Climate…
The World Meteorological Organization forecast on Oct. 8, 2026, that sea surface temperatures in the central and eastern tropical Pacific will reach record levels from October to December, as the El…
The trade winds over the tropical Pacific normally push west, piling warm water up near Indonesia. For ten days in November 2023, a patch of them turned around and blew hard toward the east. A…
Scientists at NOAA's Geophysical Fluid Dynamics Laboratory report that a seasonal forecast system predicts with high skill how much sunlight will reach the southwestern United States in spring. They…
El Niño, the periodic warming of the tropical Pacific that reshapes weather around the world, may be about to reach a strength never recorded. Only months ago the ocean was in the opposite state: in…
Across several large ensembles of climate models, a warm North Atlantic leaves the tropical Pacific slightly warmer rather than cooler, according to a study published Sept. 18, 2026 in npj Climate…
Amazon trees that have had half their rain taken away for more than two decades came through the record 2023 El Niño drought in better shape than untreated trees nearby, researchers report in a study…
