Short summary
This study of methane (CH4) and carbon dioxide (CO2) emission modes from 40 lakes along a latitudinal transect in Alaska revealed that thermokarst lakes formed in Pleistocene-aged icy, organic-rich yedoma-type permafrost had the highest emissions. Ebullition and diffusion were the dominant modes of CH4 and CO2 emissions, respectively. Accounting for the global warming potentials of the gases, the climate warming impact of lake CH4 emissions was 2 times higher than that of CO2.
