Importance of this Unit to the Course
This unit provides background information on the amounts of carbon in the atmosphere, ocean,
and on land. This information will assist us in understanding how humans are changing these
amounts and what the consequences might be for global warming.
Objectives
Preparation for Discussion (You must complete this section before class.)
Discussion
(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:
If carbon dioxide (molecular weight 44) is so much heavier than nitrogen (molecular weight 28) and oxygen (molecular weight 32), why doesn't it have a higher concentration near the surface?
