As solar energy interacts with carbon dioxide, water vapor, and several other gases in the troposphere, it warms the troposphere process known as the Green house effect.
- Troposphere is the lower most part of the earth's atmosphere comprises of Nitrogen, Oxygen, Argon, Carbon dioxide and Water vapour.
- Carbondioxide, water vapour and other gases like methane are concentrated highly in the Trophosphere due to some human activities (Industrial revolution).
- Such excess Green house gases forms a shield layer which retains the heat by trapping the long wave radiation of solar energy in troposphere. As a result, global warming and abnormal weather conditions occurs in the planet.
