Short summary
It is unknown if lakes are important contributors to the total transfer of greenhouse gases between high Arctic regions and the atmosphere. We measured the transfer of carbon greenhouse gases between lakes and the atmosphere and compared results with adjacent landscapes. We found lakes were weak emitters of the gases to the atmosphere, compared to contributions of terrestrial ecosystems, and will likely continue to be inconsequential to regional carbon cycling in a warmer future climate.
