Experiments have shown that ocean acidification due to rising atmospheric carbon dioxide concentrations has deleterious effects on the performance of many marine organisms(1-4). However, few empirical or modelling studies have addressed the long-term consequences of ocean acidification for marine ecosystems(5-7). Here we show that as pH declines from 8.1 to 7.8 (the change expected if atmospheric carbon dioxide concentrations increase from 390 to 750 ppm, consistent with some scenarios for the… 
Coral and mollusc resistance to ocean acidification adversely affected by warming
Increasing atmospheric carbon dioxide (CO2) concentrations are expected to decrease surface ocean pH by 0.3‐0.5 units by 2100 (refs 1,2), lowering the carbonate ion concentration of surface waters.
Ocean acidification effects on in situ coral reef metabolism
TLDR
The results show a decrease in 24-h net community calcification (NCC) under high pCO2, and a reduction in nighttime NCC that attenuated and eventually reversed over 21-d, which contribute to previous studies on ecosystem-level responses of coral reefs to the OA conditions projected for the end of the century.
Impacts of ocean acidification in naturally variable coral reef flat ecosystems
Ocean acidification leads to changes in marine carbonate chemistry that are predicted to cause a decline in future coral reef calcification. Several laboratory and mesocosm experiments have described
In situ changes of tropical crustose coralline algae along carbon dioxide gradients
TLDR
Declines were steepest at near-ambient pH, suggesting that CCA may have already declined in abundance due to the recent seawater pH decline of 0.1 units, and that future severe losses are likely with increasing ocean acidification.
Effects of Ocean Warming and Acidification on Rhodolith/Maërl Beds
Coralline algae are expected to be adversely impacted by global warming and ocean acidification, although there has been no synthesis of these effects on habitat-forming species. We compiled
Vulnerability of Coral Reefs to Bioerosion From Land‐Based Sources of Pollution
Ocean acidification (OA), the gradual decline in ocean pH and [ CO32−] caused by rising levels of atmospheric CO2, poses a significant threat to coral reef ecosystems, depressing rates of calcium
Ocean acidification weakens the structural integrity of coralline algae
TLDR
The first long-term perturbation experiment on the cold-water coralline algae is presented, which shows a weakening of the structure is likely to reduce the ability of the alga to resist boring by predators and wave energy with severe consequences to the benthic community structure in the immediate future.
Global change differentially modulates coral physiology and suggests future shifts in Caribbean reef assemblages
TLDR
While ocean warming is a severe acute stressor that will have dire consequences for coral reefs globally, chronic exposure to acidification may also impact coral physiology to a greater extent than previously assumed, the variety of responses to global change across species will likely manifest in altered Caribbean reef assemblages in the future.
Experimental reef communities persist under future ocean acidification and warming
Coral reefs are among the most sensitive ecosystems affected by ocean acidification and warming, and are predicted to shift from net accreting calcifier-dominated systems to net eroding

Coral Reefs Under Rapid Climate Change and Ocean Acidification
TLDR
As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided.
Volcanic carbon dioxide vents show ecosystem effects of ocean acidification
TLDR
The species populating the vent sites comprise a suite of organisms that are resilient to naturally high concentrations of pCO2 and indicate that ocean acidification may benefit highly invasive non-native algal species.
Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
TLDR
13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.
Geochemical consequences of increased atmospheric carbon dioxide on coral reefs
A coral reef represents the net accumulation of calcium carbonate (CaCO3) produced by corals and other calcifying organisms. If calcification declines, then reef-building capacity also declines.

TLDR
It is shown that increased levels of CO2 can profoundly affect the settlement of a wide range of benthic organisms and small crustaceans was able to settle and survive under these conditions.

TLDR
It is argued that it is unclear as to how, and to what extent, ocean acidification will influence calcium carbonate calcification and dissolution, and affect changes in community structure of present-day coral reefs.
