Readings on Climate and thinking about feedbacks in earth systems

To augment the lecture's this week and next, please read the 3 short essays that I have handed out:
Did Tibet cool the world?, New Scientist, 1993
Staggering through the Ice Ages, Science News, 1994
Good news and bad news, Discover, 1994

Write several sentence answers to each of the questions at the end of each essay.
Write a one page review of examples from each of the readings that illustrates the interconnectedness among the atmosphere, hydrosphere, and lithosphere and how changes in one process in one place may have far reaching effects elsewhere on other processes. Can you identify examples of positive and negative feedbacks* in the climate system?

*(Not some killer Jimi Hendrix guitar string tooth manipulation close to the speaker psychedelic musical sounds...) Feedback mechanism triggers a subsequent event that either promotes or reverese the effects of a subsequent event.

Due next week, October 3 at the beginning of class
