Readings:

The text for the class is:

·         Bradley. 1999 Quaternary Paleoclimatology (2nd Edition) Academic Press.

Additional readings will be placed on reserve in the Geography and Map Library. They are taken from:

·         Crowley and North. 1991. Paleoclimatology.  Oxford University Press.

·         Hartmann. 1994. Global Physical Climatology. Academic Press.

·         IPCC. 1996. Climate Change 1995: The Science of Climatic Change. Cambridge University Press.

·         Robinson and Henderson-Sellers. 1999. Contemporary Climatology. Longman.

·         van Andel. 1994. New Views on an Old Planet. Cambridge University Press.

And relevant journals.

 

Some friendly reminders:

1.        Turn up to class. The lectures will not be directly from the readings.

2.        Do your readings. They are designed to enhance the learning experience not to needlessly burden you.

3.        Hand in assignments in on time. Late submissions will be penalized by a 10% deduction for each 24 hour period.

4.        Attend the exam. I will ask you fair questions based on the course material (there will be no surprises!).

5.        The University has policies regarding cheating and plagiarism. Please be aware of those policies, I will adhere to them without exception.

6.        I expect all students to show courtesy to myself and each other during class periods.

This is an 8- week course so you will need to keep up with the readings and assignments. Try hard not to miss class meetings.
