Ch 23: Climate Change & Air Pollution

About This Chapter

View these lessons to review facts about the causes of climate change and global warming. Get information on the thinning of the ozone layer, natural factors that contribute to climate change and the impact of air pollution.

Climate Change & Air Pollution - Chapter Summary

Let the lessons in this chapter help you review facts about climate change and air pollution. Our instructors discuss why the thinning of the ozone layer is harmful and what is causing global warming. You'll study the impact of global climate change and how these harmful effects can be mitigated. Other lessons explore sources of air pollution and how air pollution differs according to a nation's industrial development. After working through these lessons, you should be ready to:

  • Define air pollution and list its sources and types
  • Contrast air pollution in developed and developing nations
  • Discuss past climates and climate change
  • Share methods for determining past climates
  • Identify natural causes of climate change
  • List evidence of human-induced climate change

You can access these brief lessons whenever your schedule permits on a computer or mobile device. The quizzes that follow each lesson let you gauge your learning and determine where you might need extra review. Written transcripts of each video are available, allowing you to read along with the instructor.
