GREENCYCLES Biogeochemistry and Climate Change Research and Training Network: News


European Geosciences Union
General Assembly 2008
Vienna, Austria, 13– 18 April 2007


GREENCYCLES network members organises the session BG4.1 'Biogeochemical feedbacks on global climate change' at the EGU General Assembly 2008 on Friday, 18 April 2008.

Session Information - Programme of talks - Posters

Convener: Friend, A.
Co-Convener: Betts, R., Poulter, B., Lenton, T.

This session aims to include research progress on the understanding of biogeochemical controls on the atmospheric concentrations of anthropogenic greenhouse gases, with an emphasis on potential feedbacks resulting from climate change impacts on the surface fluxes of those gases. We are particularly interested in surface fluxes with a strong biological component and wish to give equal attention to marine and terrestrial feedbacks.

This session is supported by the GREENCYCLES network (, and all interested researchers both within and outside the network are invited to submit abstracts.
