Climate Literacy
About Teaching Climate Literacy

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.

Teaching Tips

About the Science

  • Map uses the relationship between the distribution of human population density and climate as a basis to develop a global index of predicted impacts of climate change on human populations.
  • It is reported in this news item: http://www.mcgill.ca/newsroom/news/item/?item_id=172326
  • Taken from this article: http://chairedb.uqar.qc.ca/documents/2011Samsonetal.GEB.pdf
  • The data sources are included in the article.
  • The map uses the acronym - CDVI - that refers to the climate demography vulnerability index developed in the article.
  • Challenges the notion that the areas of highest climate change impact on human populations would be the same as the areas of highest climate change impact measured in biophysical terms. To understand this point, however, the educator will have to be familiar with the methodology used to produce it. The kinds of analysis required to produce this map are not apparent from the map itself.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • This is a provocative map - challenging the notion that the areas of highest climate change impact on human populations would be the same as the areas of highest climate change impact measured in biophysical terms.
  • To understand this point, however, the educator will have to be familiar with the methodology used to produce it.

Technical Details/Ease of Use

  • The quality of the image in the pdf of the original article (http://chairedb.uqar.qc.ca/documents/2011Samsonetal.GEB.pdf) is higher than the one in the resource URL.
  • Educators will need the original article in order to present this map.
  • This visual and associated paper are possible way of engaging other fields (i.e. sociology, social studies, etc.)
  • A highly specialized resource, with data missing in Sahara and Australia.
