... , perturbations of the N inputs from air pollution or fertilization will also cause long-lived ecosystem changes (34, 36, 44~. Analyses of the past interannual variability of the carbon cycle, and of its potential future behavior, must consider mechanisms that act through the coupled water/energy, carbon, and nitrogen cycles.
