This video from Grist explains geoengineering, specifically solar geoengineering, and uses metaphors and visual representations to explain the potential benefits, dangers, and unknowns of geoengineering.
It uses easy-to-understand demonstrations, including a geoengineering simulator and a poor-tasting lemonade demonstration.
It is under five minutes but still gives students a clear understanding of what geoengineering is, why it might be a problem, and why we still might need to study and implement it.
There are bleeped-out swear words at the end of the video.
Students should have a basic understanding of fossil fuels and the greenhouse effect.
Students can come up with their own metaphor or visual representation to demonstrate geoengineering.
This video can be used in an English class as an introduction to a class debate on geoengineering and for stating an opinion with evidence.
The description links to the Grist website for more information about geoengineering.
Geoengineering has become an even more popular idea since the production of this resource in 2019. While the physical science behind the idea would work, this video correctly highlights the inherent risk of geoengineering. In particular, some studies that model what geoengineering would do to planetary circulation show that it would shut down major weather patterns, such as the Asian monsoon season. This resource is recommended for teaching.
