AHT404 Climate Change Impacts, Mitigation and Adaptation (8)

This subject aims to give a comprehensive overview of the science and policy issues surrounding current and likely global Climate Change.


Session 2 (60)
Wagga Wagga Campus

Continuing students should consult the SAL for current offering details: AHT404. Where differences exist between the Handbook and the SAL, the SAL should be taken as containing the correct subject offering details.

Learning Outcomes

Upon successful completion of this subject, students should:
  • Be able to demonstrate a thorough knowledge of past and present climates, the science behind anthropogenic global warming, the current state of knowledge on likely Climate Change scenarios, and mitigation and adaptation efforts.
  • be able to demonstrate broad skills in climatology, geomorphology, soil science, landscape history and environmental science as they affect climate change issues.
  • be able to demonstrate an understanding of current Government policy and management systems and develop problemsolving skills as applied to Climate Change adaptation and mitigation options.
  • be able to accurately assess the significance of new Climate Change research and will gain sufficient knowledge to be able to adjudicate between conflicting evidence and theories on anthropogenic global warming.
