Objectives Upon completion of this subject students should be able to demonstrate a broad understanding of the dynamic nature of global climates and their past, present and future influence on human population patterns and activities; a familiarity with the range of techniques available for climatic reconstruction and prediction, together with an ability to assess their relative merits and limitations; an appreciation of the nature and degree of uncertainty in climatic prediction; an appreciation of the importance of a knowledge of both scientific and human components in addressing environmental issues.

Synopsis This multidisciplinary subject examines the nature, causes and future implications of climatic change and variability. Emphasis is placed on processes which are of greatest global concern such as rapid climate change, Greenhouse warming, monsoon activity and the El Nino/Southern Oscillation (ENSO) phenomenon. An assessment is made of predictive climatic models and the major types of data from fossil and historical records which are used as model input and for model validation. The subject concludes with an evaluation of the social, economic, political and broad environmental implications of predicted future changes. The field and practical part of the subject will focus on the collection and and analysis of data which provide important information for determination of patterns of climate change and variability.

Assessment Written (2000 words): 30% - Examinations (1.5 hours): 40% - Practical fieldwork and laboratory work: 30%
