Combined nutrients and warming massively increase methane emissions from lakes

Source: Science Daily

Shallow lakes in agricultural landscapes will emit significantly greater amounts of methane, mostly in the form of bubbles (ebullition) in a warmer world, which is a potential positive feedback mechanism to climate warming. Submerged plants are key predictors of methane ebullition. The combination of warming with the loss of plants appears to transform shallow lakes into methane bubbling machines.
