yep. life will adapt, though it may not life that we recognize.

As ocean warms say so long to Salmon on the northwest coast. Whether they will survive further north or simply go extinct altogether who can say.

Departing along with the salmon will be things that us humans in the area enjoy, such as smoked salmon and salmon on the BBQ. In the grand scheme of things likely trivial, but enormous losses to our way of life, not to mention local economies.

Greater than that are the impacts on local First Nations of whose cultures the salmon historically played a incredible role, which resulted in an outsized impact of the fish on their art, story and culture. Will be devastating when the fish disappears.

The biggest unknown impacts will be on the greater forest ecology, as it has been noted that the bears eat the salmon and drag it into the woods, where it provides food for other animals and nourishes the forest in general. As the salmon disappear there could well be a cascade of disruption and extinction on animals and ecologies well beyond what we're aware of.

The salmon will go away and yes earth will "survive" and I'm sure some another fish (or maybe just jellyfish) will fill the void. But the disruptive impacts will be utterly enormous.
