Video length 5:04 min.
This is a video that discusses how climate feedbacks influence global warming.
To provide students with a better undertanding of what a feedback mechanism is/does and the difference between positive and negative feedback.

TEACHING NOTES / CONTEXT FOR USE
Teaching Tips (developed by CLEAN Reviewers)
- Use as a resource after teaching about the carbon cycle and greenhouse effect.
- Run video through once, and then restart it to eliminate commercial for classroom use.
- Educator may want to use accompanying visual examples of ocean acidification, ice albedo, and water vapor as a greenhouse gas.
About the Science
- A British scientist, who has been involved with IPCC AR4, explains amplifying feedback. The primary focus is on how water vapor functions as a greenhouse gas, but he also cites other examples of climate feedbacks - ice albedo and ocean acidification.
- Passed initial science review - expert science review pending.
About the Pedagogy
- Good and accessible explanation of what a feedback mechanism is/does and the difference between positive and negative feedback.
- This is strictly an interview with a scientist - no visuals to illustrate.
Technical Details/Ease of Use
- Brief commercial at beginning of video.
