Atmospheric concentrations of many greenhouse gases, in particular carbon dioxide and methane, are rapidly increasing from preindustrial levels. This paper explores the potential feedback from northern wetlands, particularly with regard to carbon dioxide and methane flux, to climate change. Although progress has been made in determining current trace gas fluxes from major biomass, the authors believe that a mechanistic approach is necessary to predict the direct and indirect feedbacks between climate and northern wetlands. Relevant areas covered in the article include the following: feedback mechanisms; carbon and nutrient mineralization; the kinetics of carbon and nutrient mineralization; methane oxidation and the role of plants; field dynamics of gases in a meadow and bog in Minnesota; and extrapolating to larger scales. 80 refs., 8 figs., 1 tab.
