Teaching Tips

  • Educator may need to explain some of the background information about where data comes from and how it is or has been collected.
  • Best paired with study of the reasons behind the data shown by the visualizations.
  • This is simply a visual of change over time for these indicators. Educator will need to provide the context for use and implications of these changes.
  • Please see the supporting URL for more information about the topics in these visualizations.

About the Science

  • NASA has provided a visualization of four different sets of data: (1) a shrinking perennial ice cover based on satellite imagery, (2) affected areas of sea level rise on US coastal regions, (3) changes in atmospheric CO2 concentration, and (4) changes in surface air temperature. Each visualization clearly states the range of years shown and the base measurement by which the change is measured.
  • Sea ice extent visual is limited to Arctic.
  • Projected sea level rise is limited to several parts of the globe with low lying areas, including the Gulf Mexico from east TX to FL.
  • All animations are based on reliable observations with original sources credited.
  • Comments from expert scientist:
    Excellent overall tool. Comments below are on specifics; on the whole this presentation meets the highest scientific standards for what I would consider up to the middle or high school level.
    - Visualizations need a legend or interpretation overlay. There is too little in the text to easily link understanding to what is being shown.
    - Could use more effective links within the text or at end to additional outside materials.

About the Pedagogy

  • No instructional materials are included, however, visualizations are easily inserted into any teaching unit to support the concept of human-caused climate change.
  • Educators will need to provide the context and explain some of the variables presented.
  • Students studying information displayed in the visualizations will both find answers to questions as well as possible new information to explore.

Technical Details/Ease of Use

  • Very easy to view and interact with. The most recent data for the visualizations is through 2009 or 2012.
