Abstract
This subject aims to give a comprehensive overview of the science and policy issues surrounding current and likely global Climate Change.
Syllabus
Basic Climatology and weather patterns influencing Australia

The Global Carbon Balance
Carbon pools and their relative significanceOceanAtmosphereTerrestrial pools eg. soils, vegetationResidence times and fluxes between pools
Climate modelling and GCMs
Scope, parameters and limitations of currently used GCMsModel skill (how well do these models explain current climate)Scenario building ? (likely input parameters)Realisations (different model runs and their limitations)
Evidence for Recent Climate Change
Global air temperature records (ground based and satellite)Sea level risesArctic sea ice declineGlobal glacial retreatAnimal behavioural modificationsChanges in floral timings, eg. flowering, fruit set, harvest timesSpecies extinctions and vulnerabilitiesIncreases in extreme events eg. heatwaves, fires, drought severity, hurricanesOcean acidification
Future Climate Scenarios and the IPCC
Likely climates in 50, 100 yearsPositive and negative feedbacks as the climate warmsEg. permafrost melting
Impacts of impending climate change
Rates of change, magnitude of change and their implications for humans and natural resourcesLikely risks and their magnitudesPotential threshold events and the likelihood of exceedanceScale of impacts
Adaptation and Mitigation Responses
PolicyIPCC and global responsesAustralian policy responses (AGO, NCAS etc.)Emissions trading/carbon credit schemesScienceRole of soil and land management etc.Monitoring natural resource conditionCarbon accounting
Change management theory and practice
What is change, and how do we manage it?Monitoring climate changeManaging climatic variability in agriculture
The role of Governments, Business, NGOs, other Institutions and the general populace in adapting to, and mitigating climate change
Sustainability auditsRecycling (closing the resource use loop)Environmental educationRenewable energy technologies (solar, wind, waves, tides)New industry opportunities (eg. biochar)
Impact of climate change on fundamentals in science (ie. Does a trending climate change the basis of many scientific assumptions? Are there opportunities for new scientific endeavours as a result of rethinking these assumptions?)
Future Research opportunities
Learning outcomes
Upon successful completion of this subject, students should:
1.
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.
2.
be able to demonstrate broad skills in climatology, geomorphology, soil science, landscape history and environmental science as they affect climate change issues.
3.
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.
4.
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.
