Climate Literacy
About Teaching Climate Literacy

Environmental observations are the foundation for understanding the climate system. From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.
About Teaching Principle 5
Other materials addressing 5b
Incidents of extreme weather are projected to increase as a result of climate change. Many locations will see a substantial increase in the number of heat waves they experience per year and a likely decrease in episodes of severe cold. Precipitation events are expected to become less frequent but more intense in many areas, and droughts will be more frequent and severe in areas where average precipitation is projected to decrease.
About Teaching Principle 7
Other materials addressing 7c
Ecosystems on land and in the ocean have been and will continue to be disturbed by climate change. Animals, plants, bacteria, and viruses will migrate to new areas with favorable climate conditions. Infectious diseases and certain species will be able to invade areas that they did not previously inhabit.

Teaching Tips

  • As part of a unit on climate change, students could research observations by indigenous people from varied locations.

About the Science

  • The two Navajo Elders' observations include changes in the rainy season, more violent storms, and changes in the characteristics of both wind and snow. They describe the disappearance of some plants and express concern about how changes in climate are negatively affecting people and animals.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • A Background essay and discussion questions are provided.

Technical Details/Ease of Use

  • Grainy when viewed online in fullscreen. Best to download and watch on laptops.
