Arctic tundra is facing unprecedented warming, resulting in shifts in the vegetation, thaw regimes, and potentially in the ecosystem–atmosphere exchange of carbon (C). However, the estimates of regional carbon dioxide (CO 2 ) and methane (CH 4 ) budgets are highly uncertain. We measured CO 2 and CH...
