| Zusammenfassung |
| Natural ecosystems respond to, and may affect climate change through uptake
and storage of atmospheric CO2. Here we use the land-surface and carbon
cycle model JULES to simulate the contemporary European carbon balance and
its sensitivity to rising CO2 and changes in climate. We find that the
impact of climate change is to decrease the ability of Europe to store
carbon by 97 TgC yr−1. In contrast, the effect of rising
atmospheric CO2 has been to stimulate increased uptake and storage. The
CO2 effect is currently dominant leading to a net increase of 114 TgC yr−1.
Our simulations do not at present include other important
factors such as land use and management, the effects of forest age classes
and nitrogen deposition. Understanding this balance and its implications for mitigation
policies is becoming increasingly important. |
