A strong mitigation scenario maintains climate neutrality of northern peatlands

CH 4 ) to the atmosphere. The net climate impact of peatlands depends on the relative magnitude of these two green-house gases. Here, we assess the future CO 2 and CH 4 balance of northern peatlands using five large-scale, process-based peatland models. Our results suggest that under climate policies and action, northern peat-lands are likely be climate neutral because the climate-warming effect of peatland CH 4 emissions is offset by the cooling effect of peatland CO 2 sinks. However, if action on climate change is not taken, northern peat-lands could accelerate global warming because CH 4 emissions are projected to increase substantially, and northern peatlands may turn from CO 2 sinks to sources driven by strong warming and drying.
