2-4: Enhanced Greenhouse Climate, Transient Climate Simulations

Importance of this Unit to the Course

The equilibrium climate models described in the previous unit are somewhat simplified to give quick results of possible future climates. They overlook a key factor that the ocean, atmosphere and ice change at different rates when external heating of the climate system changes. Better evaluations of climate models and better projections of future climates can be done with transient models. Transient models give better estimates about when we can expect significant climate changes to occur.

  1. Read the summary information. (Print text for offline review; images only.)
  2. Take the Quiz
  3. Review additional reading material (this material is not covered in the quiz, but offers more ideas for online discussion)

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:
