Air: Climate and Pollution

What is the atmosphere?

· The atmosphere captures energy selectively

· Evaporated water stores and redistributes heat

· Ocean currents also redistribute heat

Climate changes overtime

· Ice core tells us about climate history

· What causes natural climatic swings

How do we know the climate is changing faster than usual

How do we know that climate change is human caused?

· Why are there disputes over climate evidence?

Interactions between climate and air pollution

· Air pollutants can travel far

· Ozone in the stratosphere is harmed by CFCs

Effects of air pollution.

· Polluted air damages lungs and tissues

· Plants are sensitive to pollutants

· Smog and haze reduce visibility

Air pollution control

· The best strategy is reducing production
