Productivity response of climax temperate forests to elevated temperature and carbon dioxide: a north american comparison between two global models

The appropriateness of using regression- and process-based approaches for predicting biochemical responses of ecosystems to global change is assessed, focusing on the responses of all temperate forests in North America. Results suggest that the process-based approach is able to progress beyond the limitations of the regression-based approach for predicting biogeochemical responses to global change.
