Studies past changes in the Earth�s climate and their application to predict future climate changes. Combines theoretical understanding of the climate system, computer models, and records of past changes from geological archives to understand drivers of past and future changes in climate. Emerging and inter-disciplinary area in climate research including paleoclimatology, climate theory, and modelling. Students work individually and in groups to formulate hypotheses that ca be tested using paleoclimate records and model simulations. Formerly offered as a special topics course. Same as ATOC 4740.
