Extreme climatic events are increasing in frequency and intensity in the sub-arctic, a rapidly warming region crucial to global carbon–climate feedbacks. Ecosystem carbon dioxide (CO 2 ) fluxes can be greatly impacted by extreme events through both immediate and long-term legacy effects. As event intervals shorten, new extremes may coincide with incomplete recovery from previous ones; yet the consequences of multiple events re...

Drought events are increasing in frequency and intensity due to climate change, causing lasting impacts on plant communities and ecosystem functioning. In the sub‐arctic, climate is changing at a rate above the global average with amplifying effects on the carbon cycle. Drought‐induced shifts in the balance between productivity and respiration might have important implications for climate change feedbacks in these regions. How...
