Weakening greenhouse gas sink of pristine wetlands under warming

Warming reduces the greenhouse gas sink of pristine wetlands. Here the authors show that carbon dioxide emissions increase in cryptogam sites at higher latitudes, while methane and nitrous oxide emissions are enhanced in vascular-plant-dominated permafrost wetlands.
