Do you emit Greenhouse gases

What is Green house gas effect?

    Green house gases are gases which trap radiation in the atmosphere.The part of  radiation comes from the sun to the earth, absorb by the atmosphere while the other part loss to the space. Such gases help to maintain surface temperature of the earth.

There are well known green house gases being defined, 

Carbon Dioxide(CO2), Water(H2O), Methane(CH4), Nitrous Oxide(N2O), Ozone(O3), Halogenated  flurocarbons (HCFS)).  

What increase, the green house gas effect?

          Green house gas emission happens due to both natural and human activities. 

Burning fossil fuels(release of CO2, CO, Hydrocarbons), deforestation(less CO2 can be consumed by photosynthesis), Land filling with organic waste(CH4 release during anaerobic digestion process  ), population growth(consume more and more energy), even during the respiration of living organisms.

How does green house effect happens?

          Earth receives most of its energy, from the Sun. This energy is electromagnetic radiation in the form of Visible light, Infrared (IR) and Ultraviolet (UV) radiation. The Earths' surface absorbs the solar energy and  releases it back to the atmosphere as Infrared (IR) radiation, some of which goes right back into space.

          But some of the IR radiation emitted by the Earth is absorbed by greenhouse gases in the atmosphere and sent back towards the Earth's surface and this warms the Earth's surface.

These gases absorb the infrared radiation emitted by the Earth and re-radiate the energy as heat back towards the Earth, causing a warming known as the greenhouse effect. 

Do we emit Greenhouse gases?

          Before we ask this question ourselves, we need to understand where, why, how and when this emissions take place.

example;

Each and every one of us consume, some sort of energy during our life time.

Where?

During the consume of electricity

Why?

We consume electricity generated by coal, petroleum power plants

When? 

During the burning of fossil fuels
How?

Burning of fossil fuels produce billion tons of green house gases such as CO2, CO, CH4....
