- This short video should be used to clarify the role of carbon dioxide in absorbing infrared energy re-radiated from Earth's surface. It will enhance student understanding of the greenhouse effect. The teacher will need to prepare to lead discussion following the video, using the essay and links provided.
About the Science
- Video includes a simple and effective demonstration of how carbon dioxide absorbs infrared radiation – an idea often presented poorly in the usual discussions of the greenhouse gas effect.
- Passed initial science review - expert science review pending.
About the Pedagogy
- This resource includes a background essay, simple discussion questions, and links to national and state standards.
- The background essay discusses the sources and sinks of carbon dioxide and the idea that some of the carbon dioxide emitted by human activities is unaccounted for. Later work http://www.nature.com/climate/2007/0708/full/climate.2007.35.html argued that this missing carbon sink is in the greater-than-expected role of tropical forests.
