Joint Seminar: Opening Pandora's box: How to constrain regional projections of the terrestrial carbon cycle

Semiarid ecosystems play an important role in the global terrestrial carbon cycle, and dominate the inter-annual variability, and trend in the global terrestrial carbon sink. This was highlighted by the 2011 La Niña event where Australia alone contributed almost 60% to the record global carbon sink, and studies suggest that the Australian terrestrial carbon sink may be enhanced due to more extreme rainfall events projected for future decades. Despite this known importance to the global carbon cycle, there is still significant uncertainty regarding the Australian carbon cycle, and its contributions to global and regional carbon budgets. In this seminar, I will discuss different sources of uncertainty in the simulation of the terrestrial carbon cycle over Australia, specifically the uncertainty associated with the choice of terrestrial biosphere model, and the uncertainty associated with the choice of climate forcing.
