Global Climate Change In Context

This subject examines the nature and causes of past changes in Earth’s climate during the Quaternary Period (the last 2.7 million years), with a particular emphasis on the last glacial-interglacial cycle. It aims to place modern climate and the projections of future global warming into a longer-term perspective, and will allow students to understand why human interference in the climate system may be a legitimate cause for concern. Emphasis is placed on how Earth materials (ice, rocks, sediments, biological materials) record past climate changes, the techniques used to extract this ‘palaeoenvironmental information’, and the principles that govern how this information is interpreted.
