【 摘 要 】

This project's scientific goal was to achieve better understanding of where land cover change may mitigate climate change, accounting for both direct climate effects as well as the impacts on the global carbon cycle. As tools for investigating this problem, several models of different complexities were used: an offline land model, a standard coupled climate model, and a model in which coupled carbon-climate interactions were explicitly represented. Results from all model simulations were qualitatively similar: climate mitigation projects involving large-scale re-growth of forests are predicted to be beneficial in mitigating future CO{sub 2}-induced global warming if these are carried out in the tropical latitudes, to be largely ineffectual if conducted in temperate latitudes, and to be counterproductive if implemented at high latitudes. Details of the quantitative differences in these predictions which are exhibited by the chosen climate models also are discussed.
