DESCRIPTION:Terrestrial biosphere dynamics\, e.g. carbon cycling and veget
 ation distribution\, are influenced by climate in many ways and on many ti
 me-scales. They affect in turn the climate system by their effects on the 
 growth rate of atmospheric greenhouse gas concentrations and biogeophysica
 l properties of the land-surface. These interactions are essential for und
 erstanding observed past and present atmospheric and climatic changes\, an
 d for projecting future climate change as the consequence of anthropogenic
  greenhouse gas emissions. Studies of these interactions rely on numerical
  models of the terrestrial biosphere \, linking processes at the scale of 
 a single leaf to processes at the scale of individual ecosystems\, biomes 
 and continents. In this talk\, I give a broad overview on some of the key 
 issues in terrestrial biosphere modelling that affect our ability to under
 stand biosphere dynamics under global change\, and biosphere-climate inter
 actions. I particularly highlight the need to account for nutrient interac
 tions in the assessment of climate-carbon cycle feedback and given an over
 view on the current understanding (and modelling capacity) of nitrogen cyc
 le interactions with climate either directly via the emissions of the gree
 nhouse gas N2O\, or indirectly\, via the effect of nitrogen availability o
 n terrestrial carbon cycling.
