GEGM21 Climate Change - Past, Present and Future
This module will examine the Earth's climate system, and the principal natural and anthropogenic forcing mechanisms controlling it. The detection and nature of recent environmental changes will be discussed within the context of the Earth's climate history . The tools and methods used to measure, predict and study climate changes will be introduced. This will include the fundamental structure of General Circulation Models and how these techniques may be employed in conjunction with instrumental and proxy data to study the climate of the past and to reduce uncertainty in future climate change projections.
