He also found large temporal variations in the imbalance with a negative imbalance, for example, in the early 1980s. (nap.edu)
Additionally, changes in TLC reflection under global warming in the models correlate strongly with variations in TLC reflection inferred from temporal variations in simulations of the present climate alone (Fig. 2b). (climate-dynamics.org)
Rapid changes in subsurface biogeochemical processes measured in a New England salt marsh coincided with temporal variations in the physiology of Spartina alterniflora (Hines et al. 1989). (link.springer.com)
