Boreal wetlands are important for wildlife and carbon storage and are being affected by multiple environmental stressors including permafrost thaw. In particular, thermokarst bogs resulting from permafrost thaw can result in large feedbacks to global climate if methane (CH4) and carbon dioxide (CO2) fluxes are large. In addition, our understanding of the environmental, chemical, and biotic interactions that control greenhouse gas fluxes from thawing permafrost environments is limited, and changes over the course of wetland development.
