Arctic soil methane consumption may be larger than previously thought and increases in a drier climate
Arctic wetlands are known emitters of the strong greenhouse gas methane (CH\4\). Well-drained soils on the other hand remove methane from the atmosphere. In the Arctic and boreal biomes, well drained upland soils with a high potential for atmospheric methane\ \consumption cover more than 80% of the land area. Despite the large upland coverage and their potential importance for methane\ \uptake, the underlying mechanisms, environmental controls and even the magnitude of Arctic soil methane\ \uptake are poorly understood.
