- These so-called biogeochemical cycles are linked: changes in the cycling of oxygen, carbon, nitrogen, and phosphorus are interdependent.
- First, while the basic biogeochemical characteristics of environmental change are generally understood, there remain major uncertainties about the feedback effects on both the physical and social processes.
