Character and definition of the Quaternary period, dating methods, a review of proxy data sources, geomorphology and climate change, Quaternary environments of the Southern Hemisphere; laboratories as required.
Palaeoclimatology is the study of climate prior to the period of instrumental measurements. The focus of this course is on the Quaternary period which spans approximately 1.8 million years. This period is of critical importance in Earth's history because it is marked by oscillations in climate that had a dramatic impact on the geosphere and biosphere including changes in sea levels, vegetation distribution, soils and landforms. These changes and the legacy of these changes continue to have impacts on environments today. In the last 20,000 years alone the area of the Earth covered by glaciers has been reduced to one-third of what it was during the last glacial maximum; waters released by melting ice have resulted in sea level rise in excess of one hundred metres, land unburdened by ice has risen by several hundred metres, vegetation belts have swung through the equivalent of tens of degrees of latitude, rainforests have expanded, desert sands have advanced and retreated, lakes have flooded and shrunk and many species of mammals have become extinct.
