Since you state that a decrease in net calcification could result from a decrease in gross calcification, an increase in dissolution rates, or both, you distinguish between these responses and get to the conclusion that the impact
of ocean acidification on a creature's net calcification may be largely controlled by the status
of its protective organic cover and that the net slowdown in skeletal growth under increased CO2 occurs not
because these organisms are unable to calcify, but rather
because their unprotected skeleton is dissolving faster.

I think the inflation would be a consequence
of that fact that (except for some things), in so far as the efficient market hypothesis applies, we would be operating optimally now except for global warming and
ocean acidification; applying the tax pulls us away from that optimum, the economy will then not be as efficient (ignoring externalities); but we should want to do this
because the economy is now more efficient when including the externalities.
The pace

oceans, since CO2 forms carbonic acid in water.
When you suggested in an reply to a comment
of mine in an older post that the planet was resilient and also mentioned the coral reefs, I thought it useless to reply in rebuttal,

because of rates
of change.
The
acidification of oceans may well be the most insidious and pervasive threat to life in the
oceans everywhere, simply
because so many different plants and animals that play key roles in ecosystems will likely be affected — coccolithophores, pteropods, corals, mollusks (clams, mussels, oysters, snails), echinoderms (urchins, seastars), arthropods (lobsters, crabs, shrimp), etc., etc..
Obviously the above assumption
of harmlessness would not be accepted on the basis
of current science, both
because of climate change and
ocean acidification processes.
Because if not, «Laboratory experiments revealed that
ocean acidification has negative impacts on the fertilization, cleavage, larva, settlement and reproductive stages
of several marine calcifiers, including echinoderm, bivalve, coral and crustacean species.
The 2009 State
of the Climate Report
of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate change is real
because of rising surface air temperatures since 1880 over land and the
ocean,
ocean acidification, sea level rise, glaciers melting, rising specific humidity,
ocean heat content increasing, sea ice retreating, glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines
of evidence.
Meanwhile, a U.N. report predicted $ 1 trillion in annual damage from

of facts.
Organisms living in Polar Regions are uniquely vulnerable to the effects
of ocean acidification because only very low concentrations
of calcium carbonate is dissolved in the water column.
Of far greater concern than corals in particular is the ocean food chain in general, because while acidification will probably result in more oceanic dead zones as the amount of CO2 goes up and the amount of oxygen falls, if you kill off the plankton and pteropods that use carbonate to make their shells, then you kill off the food supply for the vast majority of higher organisms (like mollusks, fish, and even marine mammals

Efficiency is very important in the case
of fossil fuel power stations
because fossil fuels are a finite resource — once we use them they are gone — and when burned they produce carbon dioxide and other substances that kill people and cause climate change and
ocean acidification; so it is very important to get as much electricity as we possibly can per tonne
of fossil fuel.
«'' On both a monthly and annual scale, even the most stable open
