Invited Speaker: Victor Brovkin (MPI-M) + Ken Caldeira (Carnegie Institution, Stanford, USA)

On time scales from decades to millennia global climate develops in close interaction with both terrestrial and marine biogeochemical cycles. Due to the strong human influence on the Earth system by combustion of fossil fuels, deforestation and widespread fertiliser application, the link between climate, the carbon cycle and other biogeochemical cycles is today a key issue of climate research. Observing and understanding this relationship for the contemporary period and past climates will help us understand the role of these interactions in the future and guide future sustainable environmental policies. The session aims to provide an overview on current research on these interactions from an Earth system perspective and their relevance to future climate change.
