Knowledge of the amount of carbon in the environment, especially in the form of carbon dioxide, is important for understanding global climate change. Old-growth forests in particular have been thought to be steady-state systems in which carbon uptake is balanced by carbon emission. In their Perspective, Keller et al. discuss a recent article by Grace et al. in which this assumption is challenged.
