Climate Change and Variability ( 6 points, SCA Band 2, 0.125 EFTSL)

Leader: Jason Berenger and Nigel Tapper

Offered:
Clayton First semester 2005 (Day)

Synopsis: A multidisciplinary approach to the nature, causes and future implications of climatic change and variability. This is a team taught unit. Emphasis is placed on processes such as rapid climate change, greenhouse warming, carbon cycle, monsoon activity and the El Nino/Southern Oscillation (ENSO) phenomenon which are of greatest global concern. Contributions of fossil, historical and instrumental data are critically assessed and social, economic, political and broad environmental implications of predicted future changes are evaluated in terms of the significance for biotic communities and human society. Analysis of paleo, historical and current environmental data forms is a core.

Objectives: The course aims to provide a background in how climate has changed in the past and how it is likely to change in the future. After completing the unit student swill be expected to: 1. Understand the concept of climate change and how this varies from climate variability 2. Demonstrate an understanding of how climate changes across different timescales (geological, centennial, decadal to annual). 3. Illustrate the mechanisms and feedbacks that influence climate change. 4. Show an awareness of the social and political context to climate change and the impacts, adaptation and mitigation of such change.
