In the last few million years there were massive swings in Earth (and sea) temperature.
A couple hundred million years ago there was a warm era, there were no ice anywhere on Earth.
I can see how climate change might be highly destructive to human habitat, but "90% ocean lifeform death" is the best excuse for not taking climate activists seriously.

Nature doesn't have time to adapt to such a repentine change and so another "great dying" is a concrete possibility.
