And the ocean is already doomed. Within the next fifty years or so there will be a global ecological collapse of the ocean, killing all vertebrates. Then the largest famine humanity has seen will follow. Within 150-200 years all animal life, save for small pockets here and there, will be gone from the oceans.

This has happened several times before when CO2 levels shot up, but it never went up this fast.

I really wish I didn't have kids.
