ABSTRACT
Interest in the field of environmental monitoring and quantitative assessment of environmental problems is growing. For some years now, the results of environmental models and assessment analyses have been influencing environmental regulation and policies. These results are widely cited by politicians in forecasting consequences of greenhouse gas emissions like carbon dioxide (CO2) and in advocating dramatic reductions of energy consumption at local, state, national, and international levels. For this reason and because environmental modeling is often based on extreme conceptual and numerical intricacy and uncertain validity, environmental modeling has become one of the most controversial topics of applied mathematics.
