Geoengineering: A Horrible Idea We Might Have to Do

Ask a Question

  • This video from Kurzgesagt - In a Nutshell explores geoengineering, how geoengineering might be necessary in the future, and the potential risks of geoengineering. 
  • Students will learn about the basics of the greenhouse effect, how we are currently disrupting global average temperatures, how geoengineering strategies like stratospheric aerosol injection could buy us time, and the potentially catastrophic consequences of geoengineering strategies. 
Teaching Tips


  • It presents a balanced and researched perspective on the benefits and potential risks of geoengineering.
  • It concludes that education and knowledge are beneficial whether we need to rely on geoengineering in the future or not.

Additional Prerequisites

  • The content of the video ends at 7:54 and the remaining time is an advertisement.
  • Students should know about some natural disasters and their potential harm to humans.


  • This video can be used in an English class as an introduction to a class debate on geoengineering and stating an opinion with evidence.
  • Groups of students in social studies or science classes could research geoengineering solutions and provide their recommendations to the rest of the class. Students could research stratospheric aerosol injection, nuclear fusion, direct air carbon capture, or adding iron to the ocean to boost phytoplankton growth rates.
  • The description links to their sources and further reading on the topics covered.
  • Other resources on this topic include Geoengineering: Can Techno Fixes Save Us From Climate Change? and MIT Climate Primer: Solutions.
Scientist Notes
This resource explores geoengineering, an option that injects sulphur into the stratosphere to block solar radiation from penetrating the Earth's surface. It could delay our decision to achieve carbon neutrality by 2050, but it is also beneficial to rapidly reduce global surface temperature. This concept is recommended for students to learn.
