While much attention is given to climate change-linked rises in carbon dioxide, methane is roughtly 30 times more potent as a heat-trapping gas, and as temperatures rise, methane output from freshwater sources - the primary methane emissions source - will will outpace carbon dioxide output.
In freshwater...
