Inconvenient Truth

Read Summary

The assignment requires viewing the DVD An Inconvenient Truth and answering questions based on the film. The film presents the cumulative work of leading scientists and discusses the impact of human activity on the Earth’s four spheres. The greenhouse effect is caused by the accumulation of carbon dioxide in the atmosphere, leading to rising temperatures and global warming. Scientists use various techniques to measure past CO2 and O2 levels in order to understand historical climate patterns. The film also discusses the correlation between temperature increase and global catastrophes, as well as the implications of ocean acidification and reduction in soil moisture content. The film emphasizes the importance of addressing global warming and its potential consequences.

  5. What does Lonnie Thompson use to measure past CO2 and O2 levels?Other than CO2 and O2 levels, what other parameter can he and fellow scientists determine?
  6. For tropical glaciers (e. g. , Peru), how far back in time can they go using this technique?
  7. How far back in time can they go using this technique in Antarctica?
  8. How well do CO2 levels and temperature match over this time?
  9. List the ten hottest years on record (make sure you see the Special Feature “Update”).
  10. What is the hottest year on record?

  17. Are we ahead of – or behind – China in regard to vehicle fuel efficiency?
  18. Why did Ford, GM and Chrysler undergo a harsh downturn relative to other car makers?
  19. Do we currently have the technology to solve the global warming problem?

  21. What is the correlation between temperature increase and global catastrophes? List four types of catastrophes related to temperature, and discuss the role temperature plays (some obvious of course! ).
  22. What are the implications of ocean acidification?
