Short summary

Lakes contribute 6–16 % of methane to Earth's atmosphere. We focus on methane concentrations in Greenland lakes under open-water and ice-covered conditions. Significant warming in 2012 leads to greater methane concentrations in the lakes than in 2013. Methane concentrations under ice-covered conditions were greater than under open-water conditions. Results of this study suggest that interannual variation in ground-level air temperatures may be the primary driver of changes in methane dynamics.
