- Reducing human vulnerability to and impacts on climate requires multi-disciplinary, integrated understanding
- Ecosystems on land and in the ocean have been and will continue to be disturbed by climate change
- Human health and well-being will be affected to different degrees from the impacts from climate change

Teaching Tips | Science | Pedagogy |
- High school science standards such as photosynthesis are covered.
- The video could be used to supplement lessons about the carbon cycle and food web.
- The video could be used to frame discussions about global, social, and environmental justice issues.
About the Science
- This NASA video focuses on how increased carbon dioxide from burning fossil fuels will impact agriculture around the world.
- The video clarifies the the balance between the positive impacts of increased CO2 on plant growth and the negative impacts of a warmer atmosphere on growing seasons, water availability, drought, fire, and flooding.
- The regions where food is grown now will not be the regions where the same crops will be able to grow in the future.
Comments from expert scientist:
- explanation of why there are vulnerable agricultural populations
- presentation of problem with a human population increase
- there is not a lot of in depth information about how climate change affects crops
- definitely would need to be used as an introduction to climate change impacts, not a stand alone activity
About the Pedagogy
- Depending on the intended audience, it may be necessary to clarify the role of CO2 and H2O in photosynthesis, and other biogeochemical cycles, such as nitrogen and phosphorus, as limiting factors for agriculture.
