Simulated methane emissions from Arctic ponds are highly sensitive to warming

to related objects

Abstract ∘ C on top of a historical simulation. The simulations reveal an approximately linear increase in emissions from ponds of 1.33 g CH4  yr- 1 ∘ C- 1 - 2 ∘ C above present temperatures, pond methane emissions are more than 3 times higher than now. Most of this emission increase is due to the additional substrate provided by the increased net productivity of the vascular plants. Furthermore, plant-mediated transport is the dominating pathway of methane emissions in all simulations. We conclude that vascular plants as a substrate source and efficient methane pathway should be included in future pan-Arctic assessments of pond methane emissions.
