ABSTRACT

This chapter examines the two main issues relating to global atmospheric change of ozone depletion and emissions of greenhouse gases and, therefore, provides a contrast to the generally more local atmospheric pollution caused by acidic deposition, or acid rain (see Chapter 4). Although the impact on global atmospheric change caused by human activities is emphasised, natural processes are also discussed. Central to any consideration of global atmospheric change is an appreciation of the radiation balance of the Earth's atmosphere (Figure 3.1).
