2-2: Climate Models

Importance of this Unit to the Course

In previous units we have seen that changes in the chemistry of our atmosphere are causing changes in the global energy balance. To understand how these changes will translate into changes in climate on a global and regional basis we need to use climate models. The results of these models will used in Blocks 2 and 3 to show how future environmental conditions such as water supplies, agriculture, and natural ecosystems will differ from the present.

Objectives

To identify the basic principles used to construct climate models.
To understand the strengths and weaknesses of climate models.
