The Impact

Abstract Eleven coupled climate–carbon cycle models used a common protocol to study the coupling between climate change and the carbon cycle. The models were forced by historical emissions and the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A2 anthropogenic emissions of CO2 for the 1850–2100 time period. For each model, two simulations were performed in order to isolate the impact of climate change on the land and ocean carbon cycle, and therefore the climate feedback on the atmospheric CO2 concentration growth rate. There was unanimous agreement among the models that future climate change will reduce the efficiency of the earth system to absorb the anthropogenic carbon perturbation. A larger fraction of anthropogenic CO2 will stay airborne if climate change is accounted for. By the end of the twenty-first century, this additional CO2 varied between 20 and 200 ppm for the two extreme models, the majority of the models lying between 50 and 100 ppm. The higher CO2 levels led to an additional climate warming ranging between 0.1° and 1.5°C. All models simulated a negative sensitivity for both the land and the ocean carbon cycle to future climate. However, there was still a large uncertainty on the magnitude of these sensitivities. Eight models attributed most of the changes to the land, while three attributed it to the ocean. Also, a majority of the models located the reduction of land carbon uptake in the Tropics. However, the attribution of the land sensitivity to changes in net primary productivity versus changes in respiration is still subject to debate; no consensus emerged among the models.

The ocean carbon cycle plays a twofold role in the context of climate change: (1) through carbon dioxide gas exchange with the atmosphere and carbon cycle climate feedbacks, the ocean regulates the carbon dioxide concentration in the atmosphere and hence has a strong influence on the heat budget of the Earth; (2) the paleo-climatic marine sediment core record is largely based on biogenic matter fluxes from the ocean surface to the sea floor, which are part of the marine carbon cycle. The ocean is important for global carbon cycling, primarily due to three factors: (1) the ocean is a huge carbon reservoir with a relatively short turnover time; (2) carbon dioxide in sea water is effectively dissociated inorganically into other substances; (3) marine plankton is keeping the surface ocean carbon dioxide concentration at a lower level than would a lifeless ocean. On intermediate to long time scales, the ocean provides the most important sink for anthropogenic carbon dioxide. The marine uptake kinetics for carbon dioxide work on a longer time scale than current and projected emissions by humans.
