The marine ecosystem along Southern California’s coastline is in crisis. Sea surface temperatures are hitting record highs, rivaling the devastating marine heat wave known as “the Blob” that wreaked havoc on West Coast fisheries and ecosystems a decade ago. Scientists from NOAA, Scripps Institution of Oceanography and University of California’s Agriculture and Natural Resources are warning that a developing El Niño could intensify conditions further. There are steps we can take that would relieve the pressure on these already stressed waters, and it’s past time for California lawmakers and regulators to act.
Last year, harmful algal blooms led to the illnesses and deaths of hundreds of sea lions, dolphins and seabirds off Southern California. Further north, Dungeness crab shells are dissolving in acidic waters. Fish populations and marine mammals are struggling to survive in growing oxygen-depleted zones that can stretch 50 miles from the coast. Warming ocean temperatures are accelerating all of it.
