The greenhouse effect is a natural occurrence that keeps all Earth's heat from escaping to the outer atmosphere.
Greenhouse gases are responsible for the greenhouse effect.
The greenhouse effect is a necessary phenomenon. It balances the effects of the earth-cooling processes. The greenhouse effect helps maintain Earth's average temperature at approximately 60 degrees Fahrenheit, which is necessary for life to exist on this planet. This is because it is very effective as a greenhouse gas, and there is a lot of it in the atmosphere. The sun's light energy is able to pass through the atmospheric CO 2 to the earth's surface.
