Description A factual understanding of the energy balance of the globe, how this impacts on climate and how climate has varied in the past, is essential for any person working in the climate change area. This unit will introduce students to the concept of energy balance and climate, our understanding of how climate works, and how it has changed through time. Topics in basic atmospheric science will give students a critical understanding of current environmental concerns and debates about radiative forcing (the greenhouse effect), climate change, ozone depletion, photochemical pollution and acid precipitation.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Describe the composition and structural characteristics of the atmosphere as they relate to the energy balance of the Earth, including solar radiation, aerosols, particulates, water vapour, ozone, and greenhouse gasses.
  2. Describe the major process components of the climate system, including elevated CO2, temperature, precipitation, evaporation, transpiration, and wind, evaluate terrestrial feedbacks to climate change and how these may act to modify the rate of future change.
  3. Describe the evidence for past climates (paleoclimates), including techniques to reconstruct climate through direct and indirect methods.
  4. Explain the major theories and concepts of global climate change, including model scenarios of future climate regimes.
  5. Evaluate the impact of climate change on physiology, growth, productivity and species interactions in biological systems. Understand the processes driving climate change impacts on ecosystem structure, diversity and function.
  6. Evaluate human impacts - land use changes, industrial pollution, rapid population growth - on climate variables (CO2, temperature, precipitation) and their potential impact on biological and socio-economic systems, including indigenous culture.
  7. Use spreadsheets and statistical tools in analytical programs to analyse and graph data, in order to generate appropriately conclusions.
  8. Communicate findings correctly in oral or written form using an appropriate style, accessing scientific literature to place findings into context.
