What a Super El Niño could mean for Alaska’s seabirds, salmon, and seas

NOAA has declared an El Niño in June 2026, with a "Super El Niño" expected to peak this winter. USGS researchers are tracking how warming waters threaten Alaska's ecosystems, from seabird die-offs and harmful algal blooms to heat-stressed salmon. USGS science helps reveal the connections between these climate events and the fish and wildlife that Alaskans and ecosystems depend on.
