Teaching Tips

About the Science

  • This video explains why we know that humans have caused greenhouse gas concentrations to increase.
  • Evidence includes measuring atmospheric greenhouse gas inputs and uptakes through direct measurements, satellite measurements, and analysis of carbon isotopes.
  • Comments from expert scientist: The material goes through the main greenhouse gases and provides a discussion and graphs to indicate that they are increasing in a way that is unprecedented in the records up to now. It highlights the molecules --carbon dioxide, methane, and nitrous oxide and CFCs and states information about their production and states how they are both natural and produced by humans.

About the Pedagogy

  • No additional supporting materials.
  • Video is methodical in its historical approach to the story, providing records of the scientists contributing to the study of CO2 in our atmosphere and greenhouse gas concentrations. Science-heavy video covering a lot of data.
  • Because of the wide variety of data covered in this video, students may need additional support to understand the graphs. URLs for the graphics are listed in the "Related URL" field below.
  • Graphs and other visuals may need more time for real understanding.

Technical Details/Ease of Use

  • Quality of video can be viewed in three different resolutions.
