Why doesn't air pollution cause global warming?

Answer 1

There are many kinds of air pollution, ranging from cigarette smoke to sulfur dioxide which causes acid rain. They don't all contribute to global warming. However, one does. The chief pollutant affecting global warming is Carbon dioxide (CO2).

In 2007 the United States Supreme Court ruled that Carbon dioxide is a pollutant and so the EPA (Environmental Protection Agency) has the right to regulate CO2 emissions from new cars. Any burning of fossil fuels like gasoline releases long-hidden carbon dioxide, a powerful greenhouse gas. This extra gas is too much for the natural carbon cycle to remove from the atmosphere, so it remains there capturing the sun's heat and causing global warming.
