Regulating Greenhouse Gases

KQED, Teachers' Domain

This video highlights the work of climate scientists in the Amazon who research the relationship between deforestation, construction of new dams, and increased amounts of greenhouse gases being exchanged between the biosphere and the atmosphere.

Video length is 5:25 min.

Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of the earth. When greenhouse gases increase, more thermal energy is trapped in the atmosphere, and the temperature of the earth increases the light energy radiated into space until it again equals the light energy absorbed from the sun.

Teaching Tips

  • This video would fit in well with a science or geography unit on the Amazon, as well as a study on the carbon cycle, the greenhouse effect, deforestation, or global warming impacts by humans, especially as regards dam building.

About the Science

  • The video discusses a scientist's research on the relationship between the Amazon forest as a carbon dioxide sink, deforestation as a result of building dams, and deforestation's contribution to climate change regarding less carbon dioxide being sequestered and more methane being released from reservoirs and dams.
  • Comments from expert scientist: Good demonstration of climate change relevant measurements, i.e., measuring CO2 flux in the Amazon. Although that the explanation could be more complete. The data used is dated and has an indirect message.

About the Pedagogy

  • Video is accompanied by lesson plan, teacher's guide, transcript, background articles, and workbook for students. These supplmentary materials expand the ease of use of the video within a unit about regulating greenhouse gases.
