Synopsis
- This podcast episode from the Council on Foreign Relations centers on the controversial topic of solar geoengineering as a means to slow global warming.
- Students will learn that solar geoengineering, or the process of using aerosolized chemicals in the atmosphere to reflect sunlight, poses a variety of potential dangers, including the risk of ozone depletion, increased air pollution, reduced crop yields, and changes in precipitation.
- The podcast episode also includes a thought-provoking discussion on the geopolitics of solar geoengineering.

Differentiation & Implementation
- Social studies, government, and civics classes could use this resource to discuss the kinds of safeguards that would be necessary in order to safely implement solar geoengineering on a global scale.
- Earth science classes could examine the relationship between volcanic eruptions and cooler temperatures on earth.
- Ethics classes could debate whether the potential benefits of solar geoengineering outweigh the potential risks.
- Advanced students could listen to the podcast episode for homework in preparation for a class discussion the following day.
- Other resources on this topic include this video from Kurzgesagt - In a Nutshell on geoengineering, this podcast episode about clouds and climate change, and this media literacy activity on geoengineering.
