Climate Literacy
About Teaching Climate Literacy

Individual organisms survive within specific ranges of temperature, precipitation, humidity, and sunlight. Organisms exposed to climate conditions outside their normal range must adapt or migrate, or they will perish.
About Teaching Principle 3
Other materials addressing 3a
Human health and mortality rates will be affected to different degrees in specific regions of the world as a result of climate change. Although cold-related deaths are predicted to decrease, other risks are predicted to rise. The incidence and geographical range of climate-sensitive infectious diseases—such as malaria, dengue fever, and tick-borne diseases—will increase. Drought-reduced crop yields, degraded air and water quality, and increased hazards in coastal and low-lying areas will contribute to unhealthy conditions, particularly for the most vulnerable populations.

Benchmarks for Science Literacy

The world contains a wide diversity of physical conditions, which creates a wide variety of environments: freshwater, marine, forest, desert, grassland, mountain, and others. In any particular environment, the growth and survival of organisms depend on the physical conditions

Notes From Our Reviewers The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials

Teaching Tips

  • Watch video in full screen mode to limit distractions from ads below video.
  • The link between climate change and disease is not as well developed in the video as one might like. Recommend using the associated lesson plan on the website to make this connection clearer.

About the Science

  • The first half of the video focuses on cholera (bacteria infection from contaminated water) and the second half focuses on dengue fever (virus-based disease spread by mosquitoes).
  • Climate change is only one of many variables that relate to disease vectors. Learners should be aware of the complexities of diseases to avoid oversimplifying the topic.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • A link to a lesson plan that incorporates this video is provided just below the video screen.
  • Many of these diseases are difficult to treat or prevent medically, so it is important that we understand how they might be affected by climate change so we can predict and prepare for them.

Technical Details/Ease of Use

  • The music accompanying the video is melodramatic.
  • Low resolution video may be grainy or pixelated when projected on a large screen.
  • Advertisements on Windows to the Universe site may be distracting for some learners.
  • Original Changing Planet videos, including this one, are available here: http://www.nbclearn.com/changingplanet
