Positives

Additional Prerequisites

• This resource requires access to the Internet.
• The last five minutes is an introduction to another podcast about climate change.
• You may want to reinforce that as new information is gained from new research or technological advancements, solutions may need to change or adjust to take those insights into account (such as the realization that some of the substitute gases for CFCs were powerful greenhouse gases).
  

Differentiation

• This resource can also be used in health classes during lessons about ultraviolet radiation and cancer, or in history classes during lessons about international cooperation and treaties.
• Have students consider why the Paris Agreement has not had the same success as the Montreal Protocol.
• To have students learn more about solving environmental problems, have them listen to this podcast about peatlands and this podcast on methane emissions.
• Social studies and civics classes can use this podcast as a introduction to global treaties or as an example of international cooperation that can be modeled to address climate change.
