Document Summary
Global environmental change changes in our environment that occur because of interdependent social and ecological processes that are connected across geographic scales, from local to global (e. g. , biogeochemical cycles and climate systems; economic markets and political/governance networks). Global environmental change is a collection of processes that can be observed in localities, but with causes and consequences at multiple spatial and temporal scales.

Site-specific factors such as topography or ground cover shape its extent. Might be produced by regional processes, such as el nino, which influences weather patterns all over the globe. New flooding rhythms (regimes) might be a signal of systemic change in those processes.
