Positives

• Students engage with clearly outlined information and can hover over vocabulary terms to see their definitions. 
• The video may spark debate or comments from students, which can get them participating in class.
  

Additional Prerequisites

• Students should have a basic understanding of global warming.
• Teachers and students will need to sign in to use some of the interactive features.
• Note that the embedded video is from 2008. Advise your students to critically think about how things have changed since 2008.

Differentiation

• The information can be gained in different ways to ensure understanding (videos, text, and text summaries).
• When signed in, students have access to a toolbar where they can highlight, note-taking, view summaries, and additional resources about the chapter. 
• Consider extending this lesson by having students watch Doubt and The Cost of Carbon and then reevaluating the video from the text.  Students can write reflection or response papers to these videos to complete the lesson.
• Social studies classes can discuss risk analyses and cost-benefit analyses associated with acting on climate or continuing with "business as usual" to demonstrate that acting on climate is a win-win scenario that reduces risks.
