Holy crap. So coral bleaching in that area is basically guaranteed at this point. And some plankton and algae can’t really survive if those temperatures persist.

Also, as temperature rises, water holds less and less dissolved oxygen. At the same time metabolic rates of fish increase, which makes them require even more oxygen. The scary thing about that is at some point they lose the ability to get enough oxygen to sustain life, and then bam — the whole species dies in a day.

Remember those rivers of millions of dead fish? Yeah, it’s like that.

Or the 2000 dead penguins washing up on the coast of Uruguay just a few days ago. Apparently starved to death, though the cause is still being investigated.

But yeah the phytoplankton and algae boiling to death is triggering a catastrophic change in the ocean that is going to domino in horrible ways and I feel like I don't often see a lot of people mentioning it. It's very scary how the collapse of aquatic ecosystems is playing out.
