Avoiding environmental damage from ocean acidification requires reductions in carbon dioxide emissions regardless of climate change. 
Biotic and Human Vulnerability to Projected Changes in Ocean Biogeochemistry over the 21st Century
Mora and colleagues show that ongoing greenhouse gas emissions are likely to have a considerable effect on several biogeochemical properties of the world's oceans, with potentially seriousExpand
Anthropogenic carbon release rate unprecedented during the past 66 million years
Carbon release rates during the Palaeocene–Eocene Thermal Maximum are difficult to constrain. Comparing relative rates of carbon cycle and climate change at the event’s onset suggests emissions wereExpand

A Review of Ocean Acidification and America's Response
The effects of ocean acidification are examined and why they should help guide decisionmakers in setting CO2 emissions goals. Expand

A simple carbon-cycle box model allows for very simple quantitative insight into the evolution of climate over the next millennium. While melting ice sheets, rising sea levels, and oceanExpand
Carbon Dioxide Emission Pathways Avoiding Dangerous Ocean Impacts
AbstractAnthropogenic emissions of greenhouse gases could lead to undesirable effects on oceans in coming centuries. Drawing on recommendations published by the German Advisory Council on GlobalExpand
Calcium carbonate production response to future ocean warming and acidification
Abstract. Anthropogenic carbon dioxide (CO2) emissions are acidifying the ocean, affecting calcification rates in pelagic organisms, and thereby modifying the oceanic carbon and alkalinity cycles.Expand
Paleo-perspectives on ocean acidification.
It is argued that ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years, emphasising the urgent need to adopt policies that drastically reduce CO(2) emissions. Expand
Millennial Scale Impacts of Marine Biogenic Calcification Changes on Ocean Carbon Cycling
Ocean acidification resulting from increasing anthropogenic carbon dioxide (CO2) emissions are likely to impact calcification rates in pelagic organisms which may, in turn, lead to changes in theExpand
Redox-controlled carbon and phosphorus burial: A mechanism for enhanced organic carbon sequestration during the PETM
Abstract Geological records reveal a major perturbation in carbon cycling during the Paleocene–Eocene Thermal Maximum (PETM, ∼56 Ma), marked by global warming of more than 5 °C and a prominentExpand


An early Cenozoic perspective on greenhouse warming and carbon-cycle dynamics
Past episodes of greenhouse warming provide insight into the coupling of climate and the carbon cycle and thus may help to predict the consequences of unabated carbon emissions in the future.
Impact of elevated CO2 on shellfish calcification
[1] Ocean acidification resulting from human emissions of carbon dioxide has already lowered and will further lower surface ocean pH. The consequent decrease in calcium carbonate saturationExpand
Oceanography: Anthropogenic carbon and ocean pH
It is found that oceanic absorption of CO2 from fossil fuels may result in larger pH changes over the next several centuries than any inferred from the geological record of the past 300 million years. Expand
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.Expand
Phytoplankton Calcification in a High-CO2 World
Ocean acidification in response to rising atmospheric CO2 partial pressures is widely expected to reduce calcification by marine organisms. From the mid-Mesozoic, coccolithophores have been majorExpand
Long term fate of anthropogenic carbon
[1] Two earth-system models of intermediate complexity are used to study the long term response to an input of 5000 Pg of carbon into the atmosphere. About 75% of CO2 emissions have an averageExpand
Coral Reefs Under Rapid Climate Change and Ocean Acidification
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. Expand
Species-specific responses of calcifying algae to changing seawater carbonate chemistry
Uptake of half of the fossil fuel CO2 into the ocean causes gradual seawater acidification. This has been shown to slow down calcification of major calcifying groups, such as corals, foraminifera,Expand
Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
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. Expand
Reduced calcification of marine plankton in response to increased atmospheric CO2
It is suggested that the progressive increase in atmospheric CO2 concentrations may slow down the production of calcium carbonate in the surface ocean, as the process of calcification releases CO2 to the atmosphere. Expand
