Thaw of surficial permafrost ice bodies (ice wedges and ice-rich mounds) causes formation of ponds with enhanced emission of CH4 and CO2 . Usually these ponds develop in dry Betula nana shrub vegetation, which, when undisturbed, is a sink for both greenhouse gases. We mapped thaw pond development ov...
