| Zusammenfassung |
| The climate of the Miocene is still a challenge for Earth system models. Proxy data indicate
warmer and more equable climate conditions while models frequently arrive at opposite
results. Moreover, marine carbon dioxide reconstructions point to surprisingly low and
constant atmospheric levels which, taken at face value, would imply an enigmatic
decoupling between CO2 and climate. Here, we present first results of a modelling
sensitivity study in which we investigate the response of marine biogeochemical
cycles to environmental changes typical for the Miocene. We employ the results of
fully coupled climate simulations to run an offline model of the marine carbon
cycle, and validate the results with marine proxy records and CO2 reconstructions. |
