Course Description

Global climate is controlled by physical processes, and

by-and-large we understand what processes are involved and how they work. Actually calculating the climate that results from a given set of forcings is a much more difficult problem. This course is about how physical processes create global climate, and how changes in the rates and intensities of those processes can change climate. Along the way, we will develop a better understanding of what “climate” really means.

Three phases of growing to understand climate include getting the basic physical science background (you have already done this), understanding how the observed climate system behaves in response to physical forcings (this course), and learning how to predict the climatic response to changed forcing (barely touched in this course, but see Geog 657).
