The main objective of the project was to improve predictions of future CH₄ emissions from natural wetlands. This objective was motivated by the fact that methane (CH₄) is a potent greenhouse gas, and wetlands represent the largest natural source of atmospheric CH₄. Modeling of wetland-methane feedbacks indicates that wetland methane emissions could drive 21st century climate change, with global wetland emissions matching or exceeding anthropogenic emissions by 2100 (Zhang et al., 2017). However, modeled estimates of wetland CH₄ emissions have high variability, which reflects a lack of mechanistic and predictive understanding of the processes and interactions that control methane production, oxidation and emissions from wetlands. The project focused specifically on wetlands within boreal regions that form when permafrost thaws, because warming temperatures have (Poulter et al., 2017) and will continue (Zhang et al., 2017) to increase wetland methane emissions from this region by promoting permafrost thaw and creating new wetland area.
