<h3>Greenhouse effect</h3>

Carbon dioxide is one of the numerous greenhouse gases that exist in nature. The gases are responsible for the warming of the planet.

The more the concentration of greenhouse gases in the atmosphere, the more the solar radiation that is trapped and the warmer the earth gets.
