You can have a differential impact on biology and chemistry, so if you really want to assess what will be the status of calcifying organisms in 2100 there is one part, the chemistry, for which the organisms have no control but for the biology they can perhaps adapt and there might be a way for the organisms to mitigate the negative impacts of ocean acidification.

If large scale changes in the ocean ecology occur because of acidification the model can not reasonably be expected to capture the effects.

Raised CO2 in aquatic systems can also lead to physiological stress, difficulty in building calcareous shells etc. (as will happen if atmospheric CO2 continues to build up beyond around 700ppm - the so called ocean acidification effect).

The findings about the species» susceptibility against ocean acidification published at Scientific Reports also raise the question if coralline algae are a reliable indicator of paleo temperatures.

On acidification it's an issue for the climate negotiations if we move away from fossil fuels that will have a huge impact in enabling the oceans to recover

The oceans are warming now but they are still a CO2 sink (hence acidification), even if the rate is slowing.

I suppose that if all uncertainties are resolved in the direction of lower risk, we just might get away with BAU for the next few decades without a complete disaster (though continued sea level rise, ocean acidification and 2 degrees Celsius actually sound pretty risky to me, and the risk that there are other factors in play seems to be reinforced by paleo data on glacial - interglacial transitions).

By the way if we keep CO2 emission how can we process ocean acidification problem?

Or deal with AGW and ocean acidification by adaptation (if we can adapt which I doubt?)

The strongest argument being that ocean acidification from anthropogenic CO2 released to atmosphere is the greatest threat to the ecosystems of the world's oceans - far greater than the very slight local risk that might arise if a sub sea bed geological storage site leaked.

Ocean acidification could devastate coral reefs and other marine ecosystems even if atmospheric carbon dioxide stabilizes at 450 ppm, a level well below that of many climate change forecasts, report chemical oceanographers Long Cao and Ken Caldeira of the Carnegie Institution's Department of Global Ecology in the journal Geophysical Research Letters.

Failures in the Earth system are already beginning to occur in a number of ways at a GMT increase of only 0.8 oC; GMT does not address huge regional differences in temperature increase; a temperature target doesn't even address ocean acidification; and we are frittering our time here (and in numerous scientific papers) addressing 2oC as if it is a reasonable target???
