Arctic uplands consume atmospheric methane, but whereas methane emissions are reasonably well studied, Arctic soil methane uptake is poorly understood. High-resolution measurements show that the Arctic soil methane sink might currently be underestimated, and is driven by soil moisture and labile carbon availability, implying increased methane uptake with climate change.
