Green House Effect

Greenhouse effect has been in existence from long time which has finally resulted in global warming.

The energy radiated form sun is the main cause for survival of life on Earth; however at the most 30% of the sunlight which is directed towards Earth is deflected back into the outer space by the outer atmosphere and the rest 70% reaches the surface of earth. The energy absorbed by earth surface later on reflected back in the upward direction to the atmosphere which is termed as infrared radiation. The heat emitted from this radiation is absorbed by the elements of greenhouse gases like carbon dioxide, methane and water vapor which reduce the rate at which this heat escapes from atmosphere.

Greenhouse effect is defined as the effect these greenhouse gases have on the natural climatic conditions of the earth due to the heat which it has captured from the infrared radiation. The main point of this greenhouse effect is the greenhouse gases wrap a layer of this heat that they have absorbed around the planet there by preventing even further escape of the heat and warming up the atmosphere within this layer which ultimately leads to change in the climatic conditions and global warming.

There are two types of greenhouse effect which is naturally caused in the above said manner and man made greenhouse effect where the humans contribute to the already prevailing greenhouse effect by burning natural resources and fossil fuels like petrol, coal etc. The man made greenhouse effect increases the percentage of carbon dioxide which covers the remaining percentage of reason for greenhouse effect. The major percentage is taken by water vapor which causes greenhouse effect which is about 90% of the entire effect.

The increase in temperature indicates the changes in the atmosphere and some scientists believe that at this rate it is pretty soon that the climate will observe drastic changes though there are also some other researchers who contradicts these statements.
