Carbon Cycle & Ecosystems

The Earth's ecosystems and biogeochemical cycles (such as carbon, nitrogen, and phosphorus) both drive and respond to environmental changes ranging from local to global scales. These current environmental changes appear to be unprecedented, in both timing and geographical extent. Major uncertainties in Earth science originate from the dynamics and interactions within and between ecosystems and their biogeochemical cycles across land, ocean, atmosphere, and human activities.
