Class Description:

    This class will focus on four topics: (1) long-term controls on global climate and ocean systems; (2) short-term perturbations of the global climate and ocean system; (3) the ocean and atmospheric redox change and evolutionary stresses; and (4) examples of mass extinction events and their driving mechanisms. Each topic will be included in the lectures and discussion sections. Students are expected to gain the knowledge of using multiple geological and geochemical proxies to explain the Earth systems change through time and learn to formulate the hypotheses and testing methods for the specific events that he/she is interested in.

    Lectures – This class will include lectures and student-run seminars. Four weeks of lectures will be given in the beginning of the semester to summarize the problems, hypotheses, and questions related to the topics.

    Discussions – Students will be divided into groups, each group will be responsible for a specific topic for a week (two lectures). The group who is going to be in charge of the topic will give a presentation and lead the discussion. Students who are not giving the presentation that week will read the papers and write a critique to answer the questions posted on the web. The group in charge of the discussion should choose the most important papers including contrasting ideas in that field (will provide a suggested reference list for each discussion topic, but you can choose your own favorite!).

    No Textbook is required. Recommended textbooks and articles include:
    1. Ruddiman, W.F., 2001, Earth's Climate: Past and Future, W.H.Freeman & Co Ltd, 465p.
     2. Kump, L.R., Kasting, J.F., and Crane, R.G., 2003, The Earth System (2nd edition), Prentice-Hall, New Jersey, 432p.
    3. Any reference book in stable isotopes and sedimentary chemistry, e.g., Sharp, Z., 2006, Principles of Stable Isotope Geochemistry: Pearson-Prentice Hall, 344p. ISBN: 0-13-009139-1.
    4. Read papers in Nature, Science, and Geology related to the topics, some review papers in Earth Science Reviews, Annual Review of Earth and Planetary Sciences, etc.

    Grading:
    70% Presentations, summary sheets and participation in discussions
    30% Mini-proposal (not need to be long) and presentation on a topic that best fits your research areas or research interests. It needs to include (1) the problems, (2) the hypothesis and predictions, and (3) testing methods.
