Teaching Tips

  • There is another CLEAN resource on this story http://www.pbs.org/newshour/multimedia/chicago/index.html that includes this video, an infographic, and more background reading on the topic of urban heat island effect.
  • A good video to connect global warming to urban heat island phenomena and the serious health implications for urban inhabitants.

About the Science

  • This video discusses strategies that Chicago is using to ameliorate the urban heat island effect that has been increasing since 1945. Building green roofs is one strategy currently being implemented as part of Chicago's green design makeover.
  • Comments from expert scientist: It shows what is often referred to as a demonstration project, where they are testing the impacts of the cooling strategies. Theoretically, we know that the green roof and cool roof technologies will improve energy efficiency, and permeable pavements will improve drainage of run-off. But exactly how much energy can be saved or how much temperatures can be reduced cannot be determined with models alone, so demonstration projects are important as a source of data to evaluate their effectiveness.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • Has a transcript of the video. Even though video is focused on Chicago, the concepts described pertain to all urban areas.

Technical Details/Ease of Use

  • Excellent visual quality.
