Abstract: nder climate change, thawing permafrost may cause a release of carbon, which has a positive feedback on the climate. The permafrost-carbon climate response (?PF) is the additional permafrost-carbon made vulnerable to ...

Abstract: oupled carbon cycle?climate models in the Coupled Model Intercomparison Project, phase 5 (CMIP5), Earth system model ensemble simulate the effects of changes in anthropogenic fossil-fuel emissions and ensuing climatic ...

Abstract: There is significant interannual variability in the atmospheric concentration of carbon dioxide (CO2) even when the effect of anthropogenic sources has been accounted for. This variability is well correlated with the El ...

Abstract: AbstractUncertainty in the behavior of the carbon cycle is important in driving the range in future projected climate change. Previous comparisons of model responses with historical CO2 observations have suggested a strong ...

Abstract: n the context of phase 5 of the Coupled Model Intercomparison Project, most climate simulations use prescribed atmospheric CO2 concentration and therefore do not interactively include the effect of carbon cycle feedbacks. ...

Abstract: arbon cycle feedbacks are usually categorized into carbon?concentration and carbon?climate feedbacks, which arise owing to increasing atmospheric CO2 concentration and changing physical climate. Both feedbacks are often ...

Abstract: he magnitude and evolution of parameters that characterize feedbacks in the coupled carbon?climate system are compared across nine Earth system models (ESMs). The analysis is based on results from biogeochemically, ...
