Dear Gene,
I’d be grateful if you could explain (to a relative ignoramus) how it could be that very high levels of atmospheric CO2 in the Cretaceous did not so reduce ocean pH as to impair coral calcification, which is a concern today? Were the oceans better buffered? Or must we assume that, given time, organisms adapted?
