MET 112 University of California Environmental Science Exercises
Class activity on climate feedback.
1. Please point out examples in the figure below for:
(a) Trend
(b) Oscillation
(c) Random variations
(d) Jump
Where do you see their combinations?
2. If you were to break up the data, what are the trends over the following time periods
(1) 1880-1920; (2) 1920-1940 and (3) 1970-2000
3. What is a positive feedback? What is a negative feedback?
4. What is the sequence of feedback for “ice-albedo feedback” under a warming climate?
5. What is the sequence of feedback for “water vapor feedback” under a cooling climate?
6. For cloud feedback, which cloud type has a positive feedback, and why is that?
