The course "Global Change" is primarily concerned with emerging Earth environmental changes. This course explicitly covers the biogeochemical cycles of pollutants: the complete path that a pollutant takes through biosphere, atmosphere, hydrosphere, and lithosphere. Topics also include the factors that control the composition of seawater, the processes by which the sea affects the atmosphere and the solid earth below, the interactions the organisms that live in the sea, and carbon and nitrogen cycles during the Anthropocene.
