Though they occupy a small fraction of the Earth’s surface, freshwater wetlands are the largest natural source of methane going into the atmosphere. New research identifies an unexpected process that acts as a key gatekeeper regulating methane emissions from these freshwater environments.The study describes how high rates of anaerobic methane oxidation substantially reduce atmospheric emissions of methane from freshwater wetlands.
