Forest age can determine the capacity of a forest to uptake carbon from the atmosphere. Yet,
a lack of global diagnostics that reflect the forest stage and associated disturbance regimes
hampers the quantification of age-related differences in forest carbon dynamics. In this
study, we provide a new global distribution of forest age circa 2010, estimated using a
machine learning approach trained with more than 40,000 plots using forest inventory,
biomass and climate data. First, evaluation against the plot level forest age measurements …
