The Global Carbon Cycle and its Role in the Climate System

Ocean and land biosphere take up about 50% of anthropogenic carbon
emissions thereby dampening the climate impact of human activity
considerably. Climate change on the other hand is expected to weaken the
land and ocean carbon sinks through changing the physical and
biogeochemical parameters related to carbon uptake. In this seminar talk
I will give an introduction to the global carbon cycle and discuss our
current understanding of the contemporary carbon sinks. Further, I will
show some results for carbon cycle feedbacks (the projected weakening of
the sinks) as simulated by CMIP5 earth system models. The talk will
probably be a bit ocean focused, but I will try to keep it general.
Jörg Schwinger obtained a PhD in Geophysics from the University of
Cologne, Germany in 2006. He worked with modelling atmospheric chemistry
and data assimilation at the Rhenish Institute for Environmental
Research, Cologne. Since 2010 he is employed as a researcher in the
Global Biogeochemical Cycles Group at the Geophysical Institute/Bjerknes
Centre in Bergen, Norway. His main research areas are the modelling of
biogeochemical cycles in the ocean and assessing carbon cycle feedbacks
in coupled earth system models.
