Increased amounts of these greenhouse gases could eventually result in warmer temperatures, melting of the Polar ice caps, rising sea levels, and flooding of coastal areas.

Most scientists agree that an increase in the amount of greenhouse gases entering earth's atmosphere causes an increase in melting of polar ice caps.
