Joint Seminar: The Global Carbon Project - Land Carbon

The Global Carbon Project (GCP) was formed in 2001 to establish a common and mutually agreed knowledge base to support policy debate and action to slow down the increase of greenhouse gases in the atmosphere. Its scientific goal is to develop a complete picture of the global carbon cycle, which is annually published since 2007 as the global carbon budget (GCB).

In this first of two seminars, we will give an overview about the GCP and the recent GCB, and present the land component of the carbon cycle in the GCB. Since the terrestrial ecosystem not only provides a potential carbon sink for fossil fuel and industrial emissions but also a potential carbon source due to anthropogenic land use emissions, disentangling these two roles of the land component is an important aspect of the GCB. We outline how land use emissions and the land sink are estimated with different model types and give some insights into our work at the MPI-M investigating differences among model outcomes. Furthermore, we present some side projects building on model simulations conducted for the GCB.
