Recently, methane has been receiving increased attention since it is the second-most important GHG in the atmosphere, with a global warming potential 28 times higher than that of CO\({}_{2}\) over a 100-year time frame [10]. Its concentration in air is nearly three times higher than that recorded in 1750, with a stepwise increasing trend characterized by a relatively stable period from 2000 to 2007 and a renewed and rapid growth since 2007 [11; 12; 13]. The causes of such impressive CH\({}_{4}\) increment are not fully understood and may include both increasing emissions from anthropogenic sources and/or natural ecosystems and a decline in the oxidative capacity of the atmosphere [14; 15; 16]. According to [PERSON] et al. [17], aquatic ecosystems are currently responsible for half of global CH\({}_{4}\) emissions to the atmosphere and their contribution is destined to increase as a consequence of global warming and human alterations. Nevertheless, these estimates are still affected by large uncertainties, mainly because it is not clear how the physico-biogeochemical factors regulate the release of GHGs from aquatic reservoirs to the atmosphere.
