Climate Literacy
About Teaching Climate Literacy

Climate plays an important role in the global distribution of freshwater resources. Changing precipitation patterns and temperature conditions will alter the distribution and availability of freshwater resources, reducing reliable access to water for many people and their crops. Winter snowpack and mountain glaciers that provide water for human use are declining as a result of global warming.

Benchmarks for Science Literacy

Fresh water, limited in supply, is essential for some organisms and industrial processes. Water in rivers, lakes, and underground can be depleted or polluted, making it unavailable or unsuitable for life.

Teaching Tips

  • This visualization is available also here: http://ga.usgs.gov/edu/watercycle.html (at this site you can get a text-free version of the diagram that might be useful as an assessment)
  • Educator should look at the links on the visualization page to see connections to climate change.

About the Science

  • The visualization as a stand-alone does not connect to climate change. Educator must use other information at EPA climate change website to provide opportunities to make that connection. For example, the water resource impacts link at the top right brings the reader to a section that discusses the impact of climate change on regional water resources.
  • Comment from expert scientist: The material does a very good job of explaining how the water cycle is already changing and the implications of such change. The water cycle graphic from USGCRP (2009) is very appropriate.

About the Pedagogy

  • This visualization provides a comprehensive overview of the water cycle without adding a lot of potentially confusing details.
  • It will work well as a focal diagram for a unit on the water cycle.

Technical Details/Ease of Use

  • The diagram can be viewed online and saved from a web browser. Images in other formats and sizes are not available.
