Read here. Alarmists and anti-CO2 activists have loudly suggested that sea water that becomes more "acidified" will significantly harm marine species. Listening to the alarmists, one would surmise that mollusks such as clams and oysters would literally have their shells disappear from lower pH levels of oceans.
A new peer reviewed study by Parker et al. punctures this hot air balloon of alarmism with empirical evidence from actual experiments.
"The authors write that studies on the impact of ocean acidification on marine organisms that have been conducted to date "have only considered the impacts on 'adults' or 'larvae', ignoring the potential link between the two life-history stages and the possible carry-over effects that may be passed from adult to offspring,"...placed adults of wild-collected and selectively-bred populations of the Sydney rock oyster which they obtained at the beginning of reproductive conditioning - within seawater equilibrated with air of either 380 ppm CO2 (near-ambient) or 856 ppm CO2 (predicted for 2100 by the IPCC)...found that the larvae spawned from adults living in the "acidified" seawater were the same size as those spawned from adults living in near-ambient seawater; but they report that "larvae spawned form adults exposed to elevated CO2 were larger and developed faster."...concluding that the results of their work suggest that "marine organisms may have the capacity to acclimate or adapt to elevated CO2 over the next century.""

Conclusion: Climate alarmists claims of the ocean acidification impact on marine species has not been factual. As researchers continue their research, the carbon dioxide emissions facts are being firmly established with empirical evidence while exposing the frequent fearmongering and exaggerations to scientific sunlight.
