Before Watching
Everyone knows temperatures in the same locations vary from day to day and from season to season. However, the really important changes are not the daily weather variations in one place, but rather long-term climatic changes averaged over the entire globe. To detect climate change, you must do much more than observe the local daily weather. As students watch, have them list ways scientists try to sort through appropriate data to find climate trends.
After Watching
Ask students to discuss the trade-offs, economic and social, of trying to reduce carbon dioxide emissions when the extent of the threat is unknown, or when the threat may be in the distant future rather than imminent. What are the risks of doing nothing? Have students list specific changes they are willing to make to reduce their consumption of energy. Have students identify other problems society faces that involve trade-offs for the sake of the greater good of the entire population.
