I can agree with all that. The only issue is that the rates we are seeing are estimated at 100-200x faster than during the great greening. So there are issues with how a system adapts. The ocean acidification can outpace the ability for marine life to adapt which can create a cascade of failures. Current estimates put the rate of change of ocean PH at roughly10x faster than any period in the past 300 million years. Functioning ocean ecosystems are critical to human flourishing. 20% of the protein humans eat come from the oceans. If the corals and scavenger animals of the seas can’t cope with the ph changes and being shell based there is evidence that they can’t it could be a rough century for the seas.
