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.
