Importance of this Unit to the Course
As discussed in previous units, the amount of carbon dioxide will double the pre-industrial revolution level before the end of this century and may reach 3 or 4 times that level. These different scenarios will create different climates that need to be described by the use of models so that we have the best available information on what adaptation strategies will be needed and what national and global policies might be necessary to protect sensitive components of the climate system.
Preparation for Discussion (You must complete this section before class.)
(online / face-to-face) (See your portfolio for due dates and times)
A major component of the course is participation in the online dialog. The following types of comments are required:
Sometimes climate models use 2xCO2 (twice the pre-industrial level of atmospheric carbon dioxide), but occasionally 4xCO2 is used? Why are these levels chosen?
