an increase in acid rain
The group of air pollutants that tends to cool the atmosphere are known collectively as:
atmospheric aerosols
Which of the following activities is responsible for the largest percentage of human-made carbon dioxide emissions?

The greenhouse effect occurs because
carbon dioxide and other trace gases trap infrared radiation in the Earth's atmosphere
The two atmospheric gases most important to humans and other organisms are
carbon dioxide and oxygen
Temperature inversions
cause gases and particulate matter to remain trapped near the ground
