San Francisco Chronicle: Climate havoc wipes out coastal kelp as SF Bay’s native fish species die off
A climate-related catastrophe off the California coast has resulted in the death of 90% of the kelp from San Francisco to Oregon as an explosion of ravenous urchins devours everything in sight. And it’s happening at the same time native fish in San Francisco Bay are dying out, two studies released Monday documented.
The studies, by government, university and scientific institute researchers, offer a disturbing look at an underwater ecosystem suffering more than anyone previously suspected — along the coast, in San Francisco Bay and in the Sacramento-San Joaquin River Delta.
