In addition, we re-evaluate some of the observational evidence for changing Arctic carbon budgets. Recent Findings Observations suggest a more active CO2 cycle in high northern latitude ecosystems.  ...  Purpose of Review The Arctic has experienced the most rapid change in climate of anywhere on Earth, and these changes are certain to drive changes in the carbon budget of the Arctic as vegetation changes  ...  Acknowledgments The authors would like to acknowledge Marielle Saunois and all of those who submitted their inverse modeling results to the Global Carbon Project for use of their results in this paper.  ...
