| Zusammenfassung |
| The atmospheric carbon dioxide concentration plays a crucial role in the
radiative balance and as such has a strong influence on the evolution of
climate. Because of the numerous interactions between climate and the carbon
cycle, it is necessary to include a model of the carbon cycle within a
climate model to understand and simulate past and future changes of the
carbon cycle. In particular, natural variations of atmospheric CO2 have
happened in the past, while anthropogenic carbon emissions are likely to
continue in the future. To study changes of the carbon cycle and climate on
timescales of a few hundred to a few thousand years, we have included a
simple carbon cycle model into the iLOVECLIM Earth System Model. In
this study, we describe the ocean and terrestrial biosphere carbon cycle
models and their performance relative to observational data. We focus on the
main carbon cycle variables including the carbon isotope ratios
δ13C and the Δ14C. We show that the model results are in
good agreement with modern observations both at the surface and in the deep
ocean for the main variables, in particular phosphates, dissolved inorganic carbon and the carbon
isotopes. |
