As solar energy interacts with carbon dioxide, water vapor, and several other gases in the troposphere, it warms the troposphere process known as the Greenhouseeffect.
Troposphereisthe lower most part of the earth's atmosphere comprisesofNitrogen, Oxygen, Argon, Carbondioxide 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 excessGreenhousegases forms ashield layer which retainsthe heat by trapping the long wave radiation of solar energy in troposphere. As a result, global warmingandabnormalweatherconditionsoccurs in the planet.
