Overview of global climate change and carbon sequestrationThis article is part of a larger document. View the larger document here.
The potential influence of global climate change on southern forests is uncertain. Outputs of climate change models differ considerably in their projections for precipitation and other variables that affect forests. Forest responses, particularly effects on competition among species, are difficult to assess. Even the responses of relatively simple ecosystems, such as managed pine plantations, will be affected by complex interactions. Large-scale perturbations, such as rising atmospheric carbon dioxide (CO2) and changes in precipitation regimes, will interact with site-specific factors such as soil nutrition.
