| Zusammenfassung |
| Future climate change will have impact on global and regional terrestrial
carbon balances. The fate of African tropical forests over the 21st
century has been investigated through global coupled climate carbon cycle
model simulations. Under the SRES-A2 socio-economic CO2 emission
scenario of the IPCC, and using the Institut Pierre Simon Laplace coupled
ocean-terrestrial carbon cycle and climate model, IPSL-CM4-LOOP, we found
that the warming over African ecosystems induces a reduction of net
ecosystem productivity, making a 38% contribution to the global
climate-carbon cycle positive feedback. Most of this contribution comes from
African grasslands, followed by African savannahs, African tropical forest
contributing little to the global climate-carbon feedback. However, the
vulnerability of the African rainforest ecosystem is quite large. In
contrast, the Amazon forest, despite its lower vulnerability, has a much
larger overall contribution due to its 6 times larger extent. |
