I suspect that some of the life in the ocean _could_ adapt, if they were not also being over-fished (or having their prey over-fished). You need a large population for variations to crop up, and then some period of time for the beneficial variations to spread out. 50-100 years is _breakneck_ speed as far as evolution goes, but if you have an annual-breeding fish then they could get 50-100 generations to adapt. Whales & dolphins may have a bad time though.

This is exactly the kind of hyperbole I'm talking about. Whales and dolphins and fish are not the totality of life in the oceans. There's krill and algae and bacteria and a bazillion other things.

Now, losing whales and dolphins and fish would be catastrophic (IMO). But that is not the same as losing all life. It is not that "some of the life in the ocean could adapt." Life in the ocean (and on land) will adapt, no question about it. It just might not be the kind of life we humans want to see. That is the problem.
