Pelicans have been spotted wandering into Peruvian ports and pushing through urban streets, searching for food they can no longer find offshore<\/strong>. It’s a strange, almost disorienting sight \u2014 but it’s also one of the earliest visible signs of something much larger unfolding across the Pacific.<\/p>\n

El Ni\u00f1o officially returned in June 2026. Even in its early stages, its ecological fingerprints are already showing up \u2014 not just on coastlines, but in satellite data streaming down from orbit, where NASA instruments are tracking changes the naked eye could never detect.<\/p>\n

A familiar climate pattern returns \u2014 stronger this time<\/h2>\n

El Ni\u00f1o’s return wasn’t a surprise. Scientists had been watching the signals build for months. What’s notable now is the projected scale and duration: NOAA’s Climate Prediction Center puts a 97% chance on this event persisting<\/strong> through early spring 2027, with continued strengthening expected through the end of 2026.<\/p>\n

Satellites have already confirmed the hallmark signatures \u2014 elevated sea surface temperatures and higher-than-normal sea surface height across the equatorial Pacific. These aren’t subtle readings. They’re the same patterns scientists tracked through previous events, now playing out in real time.<\/p>\n

The effects reach far beyond the ocean. El Ni\u00f1o reshapes weather systems globally<\/strong>, contributing to desert flooding, delayed monsoons, and shifts in tropical cyclone formation. Some of the most consequential changes, though, happen quietly \u2014 beneath the surface, where the food web begins.<\/p>\n

The ocean goes quiet: how El Ni\u00f1o starves phytoplankton<\/h2>\n

The mechanism is straightforward, even if the consequences aren’t. During El Ni\u00f1o, the easterly trade winds that normally blow across the equatorial Pacific begin to weaken, causing the warm surface layer to deepen \u2014 and shutting down the upwelling of cold, nutrient-rich water from below.<\/p>\n

Phytoplankton depend on that upwelling. Without it, their primary nutrient supply disappears and populations decline sharply<\/strong>.<\/p>\n

NASA’s PACE satellite captured this contrast directly. Comparing chlorophyll-a concentrations \u2014 a reliable proxy for phytoplankton abundance \u2014 between June 2025 (neutral conditions) and June 2026 (El Ni\u00f1o strengthening), the difference in the central Pacific, north of New Zealand, was substantial. Less green. Less life.<\/p>\n

Oceanographers Matthew Kehrli and Graham Trolley at NASA’s Goddard Space Flight Center expect the deficit to grow. The changes “may manifest as a greater difference in values across the current region, as a broadening region of reduced surface chlorophyll-a concentration, or both, depending on the behavior of the equatorial trade winds<\/strong>.”<\/p>\n

Ripple effects: from microscopic algae to fishing bans<\/h2>\n

Phytoplankton sit at the base of nearly every marine food chain in the Pacific. When they decline, the effects move upward fast \u2014 through zooplankton, to fish, to seabirds and marine mammals.<\/p>\n

Peru’s anchovy fisheries rank among the most productive in the world, but they’re acutely sensitive to El Ni\u00f1o conditions. Warmer surface waters, reduced upwelling, and lower phytoplankton abundance have historically caused dramatic catch collapses. In 2026, Peru’s Ministry of Production suspended the fishery multiple times to protect remaining stocks. The pelicans wandering into ports aren’t just a striking image \u2014 they’re a measurable behavioral shift<\/strong> driven by coastal food scarcity, echoing patterns documented during the severe 2015\u20132016 El Ni\u00f1o<\/strong>.<\/p>\n

After the disruption: the possibility of a rebound<\/h2>\n

El Ni\u00f1o’s ecological damage isn’t necessarily permanent. Research suggests that a post-El Ni\u00f1o “chlorophyll rebound” can occur \u2014 driven by higher iron concentrations in ocean currents and dust blown in from drier land areas across Central and South America. Crucially, this recovery doesn’t require a follow-on La Ni\u00f1a, though La Ni\u00f1a \u2014 which frequently follows El Ni\u00f1o events \u2014 can also elevate chlorophyll levels on its own.<\/p>\n

The clearest historical example came after the strong La Ni\u00f1a of 1998\u20131999, which triggered a large phytoplankton bloom in the eastern Pacific and a dramatic rebound in fish populations. That recovery offered a reminder that marine ecosystems can show resilience, even if the timing and scale of any future rebound remain difficult to predict<\/strong>.<\/p>\n

PACE: a new eye on an old phenomenon<\/h2>\n

What makes 2026 different from every previous El Ni\u00f1o is PACE. Launched in February 2024, NASA<\/a>‘s Plankton, Aerosol, Cloud, ocean Ecosystem satellite is now collecting near-daily hyperspectral ocean color data globally \u2014 making this the first complete El Ni\u00f1o observed at this level of detail.<\/p>\n

“The scientific community will be able to observe the 2026 El Ni\u00f1o with data across more wavelengths of light than ever before,” Kehrli and Trolley noted. That expanded spectral range means researchers can identify specific phytoplankton communities \u2014 not just total abundance<\/strong> \u2014 and track how individual species respond to shifting conditions. PACE’s sensors also measure plant pigment composition on land and monitor clouds and aerosols, both of which El Ni\u00f1o disrupts. As the event strengthens into late 2026 and early 2027, that dataset will grow into something scientists have never had before: a full-resolution portrait of how a major climate event reshapes life across Earth’s interconnected systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
