From Meteorology to Mitigation: Understanding Global Warming



About Lesson 11

We have seen that adaptation is one of the means of dealing with climate change impacts. Indeed, we will have to adapt to some changes that are in store. However, adaptation alone is unlikely to represent an adequate response to the challenges posed by climate change. That leaves only mitigation of climate change itself as an alternative. Fundamentally, there are two different forms of mitigation that have been widely considered —reduction of carbon emissions and geoengineering. Geoengineering attempts to offset the climate changes themselves through other means of human intervention in the climate system. In this lesson, we will look in more detail at the various geoengineering schemes under consideration.

What will we learn in Lesson 11?

By the end of Lesson 11, you should be able to:

  • summarize the geoengineering schemes that have been considered in the context of climate change mitigation; and
  • evaluate the relative strengths and weaknesses of different geoengineering schemes

What will be due for Lesson 11?

Please refer to the Syllabus for specific time frames and due dates.

The following is an overview of the required activities for Lesson 11. Detailed directions and submission instructions are located within this lesson.

  • Project #2 due.
  • Begin Project #3: Suppose you had 3 minutes to talk to your local congressperson about climate change. What would you tell him/her? Record a 2-3 min video, which will be available to the class to discuss and critique.
  • Participate in Lesson 11 discussion forum: Geoengineering.
  • Read:
    • Dire Predictions, p. 192-193
    • Keith 2001, Crutzen 2006, and Robock 2008. (Registered students can access the readings in the Lesson 11 module in Canvas.)


If you have any questions, please post them to our Questions? discussion forum (not e-mail), located under the Home tab in Canvas. The instructor will check that discussion forum daily to respond. Also, please feel free to post your own responses if you can help with any of the posted questions.
