Reduction in secondary pollutants

Explanation:

Global warming is the abnormal increase in the temperature of earth's atmosphere due to the presence of greenhouse gases in excess.

Greenhouse gases like methane, carbon dioxide, water vapour, etc are essential to maintain the temperature of earth and make it suitable for living. But excess amount of these greenhouse gases causes the temperature to increase beyond the tolerable level.

The possible effects are the melting of glaciers and subsequent flooding that may occur. Global warming doesn't aid the reduction in secondary pollutants.
