Lakes could be an unsuspected source of greenhouse gases
Lakes and freshwater systems account for over 20% of all methane emissions into the atmosphere. Until recently, it had been thought that methane could only be produced in oxygen-deprived environments, such as the sedimentary layers found at the bottom of lakes. In reality, surface water, even though…
