Global Scale Environmental Processes

The physical, chemical, and biological processes and their interactions that affect global change are represented by the Bretherton Diagram as discussed previously. On the Diagram, this is labeled Global Scale Environmental Processes. Thus, the six human dimension building blocks will not only interact among themselves, but will link to the Global Scale Environment Processes (i.e., the Bretherton Diagram) through the various driving forces . Driving forces originating from the six building blocks and leading to Global Scale Environmental Processes indicate human activities affecting global change. Driving forces originating from Global Scale Environmental Processes and leading to the social science building blocks express global change impacts on human activities.

The relationships among the natural science building blocks for specific scenarios within Global Scale Environmental Processes are not included in this effort. A complete evaluation of a particular global change issue consisting of both natural and social processes would require analyzing driving forces within the Bretherton Diagram (Global Scale Environmental Processes on the Social Process Diagram). Potential links between the Bretherton Diagram and the Social Process Diagram and within the Social Process Diagram itself are presented in The Diagram in Action: Three Potential Scenarios, later in this document.
