This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

This video could provide a nice introduction to the concept of positive feedbacks associated with climate change.
Video features Dr. Julienne Stroeve from the National Snow and Ice Data Center, who studies the reflectivity of snow and ice. She explains the ice albedo effect and how warmer temperatures and melting snow and ice can create a positive feedback that can increase planet warming.
Comments from expert scientist: Very important concept that is responsible for changing energy balance of the planet in a non-linear manner. Explained through words, animations, and actual examples in the "field." Has the feel of something recently produced (rather than from the 1980s). This short video serves as a good introduction, but it is not a good stand-alone resource.
Video includes simple visualizations to help students understand the concepts that Dr. Stroeve is discussing in the interview.
The video plays easily from the website, and is fairly good quality.
