About This Chapter
Human Effects on the Weather and Climate - Chapter Summary and Learning Objectives
Though air pollution has greatly decreased since passage of the Clean Air Act of 1970, it's still an issue in the U.S. and other countries. In this chapter, instructors introduce various types of air pollutants and detail ways developed and developing nations are trying to regulate them. They'll also explain the double-edged sword that is the ozone layer and discusses research and policy that's been instrumental in recovering it.
By the end of this chapter, you should be able to:
- Distinguish between primary and secondary air pollutants.
- List the six major classes of air pollutants.
- Discuss the evolution of the Clean Air Act.
- Explain ways in which ozone is beneficial.

1. What Is Air Pollution? - Definition, Sources & Types
In this video lesson, you will learn about the sources and types of air pollution. You will be able to identify the six classes of air pollutants identified by the Environmental Protection Agency and the Clean Air Act of 1970.
2. Controlling Air Pollution: How Developed & Developing Nations Differ
In this lesson, you will learn how air pollution is controlled in developed and developing nations. You will also learn about the U.S. Clean Air Act and how it has evolved over the years to address air pollution in the United States.
3. Global Warming: Atmospheric Causes and Effect on Climate
Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.
4. Basic Principles of Urban Heat Island Effects
Even though some cities are not on an actual island, they may still be considered urban heat islands. This lesson outlines the basic principles behind urban heat island effects.
