There are considerable concerns about how rising atmospheric CO2 will affect Earth's climate and marine biogeochemistry in the future. Computer simulations are used to predict future climate changes, but these projections remain very uncertain and the capacity of climate models to reproduce long-term change needs to be thoroughly tested. The only way to do this is by testing model performance against geological archives of past climate changes.

This course examines how geoscientists reconstruct climate changes in the past combining data from the oceans, atmosphere, ice sheets, land surfaces, and vegetation, and how these relate to reconstructed changes in energy supply from the sun. One important topic that we will cover, for example, concerns the reasons for past atmospheric CO2 changes, and how these influenced the global climate.

The course covers the essential aspects needed for understanding the Earth's climate system such as Earth's energy balance; climate sensitivity; sea level and ice sheet changes; ocean circulation changes; nutrient cycling and atmospheric CO2 variations. Students will learn how the geochemistry of natural palaeoclimate archives and numerical models are used to reconstruct the history of the climate system and identify the causes of climate change.  Geochemical tools and proxies used to reconstruct climate changes through Earth's history will be explained. You will learn how to use box models to understand nutrient cycling and atmospheric CO2 changes. We will look in more detail at: the nature of, and relationships between, high-resolution ice-core records from Greenland and Antarctica; abrupt climate changes; the factors that affect short-term climate variability in Australia and how these are currently changing; and the science related to common misconceptions in climate change discussions. A key outcome of this course will be a firm understanding of the physical, chemical, and biological processes that control Earth's climate, and how they may interact to modulate climate change in the future.

In addition to research-based lectures and practicals, journal articles of greater conceptual difficulty will be made available for students who wish to explore their personal interests in climate change. The teaching material is focused around areas of active palaeoclimate research and presents students with an overview of the latest international scientific understanding of past climate changes and their relevance to the future.

NOTE: Postgraduate students will attend classes with undergraduate students but will be assessed differently.

 

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Explain how the components of Earth’s climate system and carbon cycle have evolved through time.
2. Describe in depth the positive and negative feedbacks in the Earth’s land-ocean-atmosphere system that control climate change on various timescales.
3. Quantitatively analyse past climate change using elemental and isotopic tracers, palaeoclimate archives, and state-of-the-art geochronology.
4. Critically evaluate the likely causes of future climate change and assess potential impacts on feedback mechanisms.
5. Inform peers on how understanding past climate systems is important to the current debates about climate change.

Academic Integrity

Academic integrity is a core part of the ANU culture as a community of scholars. At its heart, academic integrity is about behaving ethically, committing to honest and responsible scholarly practice and upholding these values with respect and fairness.

The ANU commits to assisting all members of our community to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. The ANU expects staff and students to be familiar with the academic integrity principle and Academic Misconduct Rule, uphold high standards of academic integrity and act ethically and honestly, to ensure the quality and value of the qualification that you will graduate with.

The Academic Misconduct Rule is in place to promote academic integrity and manage academic misconduct. Very minor breaches of the academic integrity principle may result in a reduction of marks of up to 10% of the total marks available for the assessment. The ANU offers a number of online and in person services to assist students with their assignments, examinations, and other learning activities. Visit the Academic Skills website for more information about academic integrity, your responsibilities and for assistance with your assignments, writing skills and study.

Online Submission
