So, is it your contention that this supposed ocean acidification is the Fault of Man? That somehow, since it is All Our Fault, that we will be able to stop the process?
It's not a contention, it's a fact.
You can start by using the 300 acres of old coral reef in my back yard, at 4,000’ elevation.
Corals are some of the oldest critters still around, despite multi-hundred foot fluctuations of sea level; several degrees fluctuation up & down of sea temperatures, and MUCH HIGHER CO^2 concentrations during some eras.
Not only do the enviroes try to maintain that our climate is “optimum” and should be stabilized; they say the same about cliff erosion, beach formation; barrier islands, and every other aspect of nature that is in a constant state of flux and change.
They are worshipers of Darwinian evolution, but expect it to stop, now that it has reached the highest state of creation: THEM, and their pet areas.
