Importance of vegetation dynamics for future terrestrial carbon cycling

Ahlström, A.; Xia, J.; Arneth, A.; Luo, Y.; Smith, B.

Terrestrial ecosystems currently sequester about one third of anthropogenic CO$_{2}$ emissions each year, an important ecosystem service that dampens climate change. The future fate of this net uptake of CO$_{2}$ by land based ecosystems is highly uncertain. Most ecosystem models used to predict the future terrestrial carbon cycle share a common architecture, whereby carbon that enters the system as net primary production (NPP) is distributed to plant compartments, transferred to litter and soil through vegetation turnover and then re-emitted to the atmosphere in conjunction with soil decomposition. However, while all models represent the processes of NPP and soil decomposition, they vary greatly in their representations of vegetation turnover and the associated processes governing mortality, disturbance and biome shifts. Here we used a detailed second generation dynamic global vegetation model with advanced representation of vegetation growth and mortality, and the associated turnover. Weapply an emulator that describes the carbon flows and pools exactly as in simulations with the full model. The emulator simulates ecosystem dynam ... mehr
