Generally, a special type of glass house made for the production of vegetables in high latitude cold developed countries is called Green House. The glass naturally allows the incoming short wave rays of the sun to enter inside, but the glass does not allow the reflected long wave solar radiation to go out, as a result of which the temperature is trapped in this room and the indoor temperature gradually increases and becomes suitable for growing vegetables or plants.
At present the earth’s atmosphere is behaving like a greenhouse. 34% (2% from the surface, 7% from the atmosphere and 25% from cloud masses) of the total amount of radiation reaching the earth from the sun is reflected back into space by clouds, dust particles etc. This natural phenomenon of the return of sunlight from the earth is called Albedo. This reflective albedo does not heat the Earth’s atmosphere in any way, so it plays a major role in maintaining the Earth’s heat balance.
But for the last several decades, some gases and other elements in the atmosphere (carbon dioxide, methane, water vapor, nitrogen oxides, etc.) are holding the earth’s temperature like the glass walls of a greenhouse. Because, like the glass of a greenhouse, these gases allow the sun’s incoming short-wave rays to enter, but block the reflected long-wave albedo from escaping completely.
As a result, the temperature is trapped in the atmosphere along with the earth and the average temperature is gradually increasing. This phenomenon is called Green House Effect or Green House Effect.
