Highlights
- Pugh et al., 2019 utilized a new global database of forest age to inform a vegetation model.
- Regrowth forests constitute a carbon sink that is even greater than that of old-growth forests.
- This study underscored the importance of forest age data and demographic processes in terrestrial biosphere modeling.
- They challenged the traditional equilibrium view and revealed that much of the current global forest carbon sink is transient.
- In light of their estimate of a smaller carbon sink than previously anticipated, even more immediate action on CO2 emission reduction may be justified.
