we conducted an analysis of the response of the central Great Plains to climate variability over short and long temporal scales. Our application of an ecosystem simulation model to a multivariate, regional database predicted that the region is susceptible to significant reductions in primary production in response to short-term variation in climate, a result consistent with other data. Fifty-year simulations of a climate-change scenario predicted reductions in carbon storage. However, comparisons to historical field data suggested that direct human influences on the region, via decisions about land management, have the potential at human time scales to be important controls over regional carbon balance. The critical next step is to incorporate historical and present day land-use data into the analysis to represent more accurately current conditions and potential initiala conditions for climate change. |
