Climatology (Spring 2006)

Study Guide for Final Examination

 

Class and Video Notes, Chapters 13-16 in Ruddiman

 

PART A

 

Short Essays (60 Points). I will choose one of the topics from the list below and ask you to write on it. You will NOT have the option to choose an essay topic, so you must be prepared to write on all of them!

 

1.      How do glaciers contribute to their own survival during periods of orbital warming? (Lecture notes and Chapters 13 and 14.)

2.      Where is the evidence for millennial oscillations? How is the evidence analyzed? What does it show? Describe the three theories discussed in class that might explain the occurrence of millennial oscillations. (Lecture notes and Chapter 15.)

3.      Compare and contrast a historical change in climate to that of a millennial oscillation. Where do scientists collect natural proxy data to reconstruct historical climate change? How is the evidence analyzed? What does it show? (Lecture notes and Chapter 16.)

4.      Define the theory of global warming. Discuss the “global warming” debate in the context of the hockey stick controversy: How do proponents and skeptics differ regarding the stick’s shaft and the blade?  (Lecture notes, Video [The Fallacy…], and you might wish to refer to pages 419-421 in the textbook and for really interesting but all too often misinformed writings, the Internet.)
