Even after more than two thousand generations under acidified conditions, these responses still prevail to some extent, suggesting that evolutionary adaptation may not be able to completely eliminate
the negative effects of ocean acidification.
While the threat of coral bleaching as a result of climate change poses a serious risk to the future of coral reefs world wide, new research has found that some baby corals may be able to cope with
the negative effects of ocean acidification.
A recent meta - analysis indicated a significant
negative effect of ocean acidification on calcifying and non-calcifying echinoderm larvae (n = 26 studies)[63].

According to a study conducted by marine biologists
of GEOMAR Helmholtz Centre for
Ocean Research Kiel and Rostock University within the German research network BIOACID (Biological Impacts
of Ocean Acidification), eutrophication — that is already known for its
negative effects — and rising seawater temperatures could lead to a decline
of the bladder wrack in the Baltic Sea.
While we might HOPE FOR THE BEST — that there will be a cooling trend (less sun irradiance, etc) to exactly counteract our AGW trend (even so there is the
negative effects of CO2, even without the warming —
ocean acidification, crop loss to weed, etc)-- we should then be trying to AVERT THE WORST with even more drastic GHG cuts.
Meta - analysis reveals
negative yet variable
effects of ocean acidification on marine organisms
In these studies, the smaller size
of larvae reared in
ocean acidification conditions indicates an overall
negative effect on calcification (table 1 and figure 2).
Secondly, it needs to be recognized that management
of non-climatic stressors that interact and reinforce the
negative effects of warming and
ocean acidification can go some way in mitigating the
effects of climate change at the local level.
In addition to changing larval size and form,
ocean acidification has a
negative effect on survivorship
of echinoplutei, with a 10 — 20 % increase in mortality at pCO2 1000 + µatm [42].
Ocean acidification is accompanied by reduced availability
of carbonate minerals, with
negative effects on skeletogenesis, and by increased pCO2 that causes hypercapnia (increased organism pCO2) and altered metabolism [10 — 12].
Ocean acidification is often considered in terms
of its direct
negative effects on the growth and calcification
of organisms with calcareous shells or skeletons.
