California’s critical kelp forests are disappearing in a warming world. Can they be saved?

I used to scuba on the Northern California Coast. The decline in kelp has been attributed to sea urchins, whose population increased rapidly over the last couple of decades. I doubt that the temperature change in the coastal ocean has changed that much to cause this. Our ocean is quite active and cold. I bet the cause had more to do with a predator imbalance.
I believe sea urchin populations are controlled by Sea otters. So the otter population has greatly expanded, I expect, and I am certain another predator eats them, probably sharks.This same issue happens off Washington and Oregon coasts.
People/scientists changing data to support their position. truth be damned.
