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
Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species. The distribution patterns of fossils show evidence of gradual as well as abrupt extinctions related to climate change in the past.
About Teaching Principle 3
Other materials addressing 3c
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.

Benchmarks for Science Literacy
Learn more about the Benchmarks

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
Explore the map of concepts related to this benchmark
If a disturbance such as flood, fire, or the addition or loss of species occurs, the affected ecosystem may return to a system similar to the original one, or it may take a new direction, leading to a very different type of ecosystem. Changes in climate can produce very large changes in ecosystems.

Teaching Tips

  • Inclusion of a food web diagram would enhance understanding.
  • Teachers of younger students may wish to introduce the more advanced vocabulary.

About the Science

  • As apex predators, polar bears, walruses, Arctic foxes, and beluga whales are all affected by changes in the Arctic food web as a result of climate change.
  • Missing a food web diagram that could explain the effect of changes in predator populations.
  • Passed initial science review - expert science review pending.

About the Pedagogy

Technical Details/Ease of Use

  • Slightly pixelated when enlarged to view full screen. Best shown on desktop at standard definition.
