• cool air above keeps warmer air at the surface from absorbing solar radiation.
• warm air above keeps cooler air at the surface from absorbing solar radiation.
• warm air above keeps cooler air at the surface from moving upward.

The following ailments are long-term effects of air pollution except

• emphysema.
• lung cancer.
• headaches.
