Subject Overview:

The main area of study in this subject is the broad description of climates from the past treated in a global context. Emphasis will be placed on the physical processes responsible for those climates and their variability.

The topics to be covered in the subject include a broad geological-scale view of climate. Factors which influence climate, including external and geological factors, land - ice - ocean - atmosphere interactions, and stochastic effects. Energy balance models and ‘snowball’ earth. Development and decay of Ice Ages, and the role of Antarctica and the northern latitude continents. The global thermohaline circulation. Sea level variations, and the hydrological cycle. The use of paleoclimate data proxies, including foraminifera, fossils, tree rings, isotopes and the theoretical underpinnings of these. The associations between carbon dioxide and climate change.

Learning Outcomes:

The objectives of this subject are to present a comprehensive picture of how global climates have changed in the past and to explore the mechanisms responsible for those changes. It also has the objective of exploring how climate maintenance is influenced by specific issues such as greenhouse gases, ocean circulation, and the presence of Antarctica.

Assessment:

Literature survey (1000 words) (20%) and two practicals (both 3%) and two problem sets (both 7%) during semester (not exceeding 1000 words in total); a 2-hour written examination in the examination period (60%). The literature survey will be set in the first half of semester and due at the end of semester. The practicals and problem sets will be set at approximately equal intervals during semester.
