Air pollution will cause green house effect, why?

During air pollution, number of greenhouse gases increases CO₂ produced by burning fossil fuels and by respiration of animals and tends to warm the air. Similarly, nitrous oxide, methane, sulfur dioxide etc do not let solar light to escape from the atmosphere.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Air pollutants persist in the atmosphere and are carried long distance by winds, air pollution transcends local, regional and continental boundaries and it can have an effect on global climate and weather.
