    How does the Greenhouse Effect happen

    OK, let's see how greenhouse gases work in the atmosphere in 5 simple steps.

    The earth’s atmosphere is all around us.
    It is the air that we breathe.


    Sunlight enters the Earth’s atmosphere,
    passing through the blanket of greenhouse gases.



    As it reaches the earth’s surface, the land
    and water absorbs the sunlight’s energy.



    Once absorbed, the energy is sent back into the
    atmosphere in the form of infra-red rays.



    Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our globe (earth) to warm up.



    This warming is what we call Global Warming, and it is caused by the greenhouse effect.

    The greenhouse effect is important. Without the greenhouse effect, the earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the earth warmer than usual. Even a little extra warming of the earth may cause problems for humans, plants and animals.

    What brings about more Greenhouse gases?

    In this new era (the age of industrialization), the earth is full of industries. Millions of vehicles, aeroplanes and engines are produced every year. A lot of artificial things have been produced and have ended up in waste dumps. Humans produce much more waste than ever before.
    Take a good look at the simple sketch below.

    What did you notice in that sketch? What do all those activities have in common?
    They all produce a lot of smoke, fumes and water vapor!
    Simply put, human's reliance on artificial things, including all the things that make us comfortable at home, has contributed immensely to the emission of more greenhouse gases than before. These gases in the atmosphere have trapped more heat on the earth’s surface and made it warmer. This is Global Warming.

    YOU and I also produce CO2 and other greenhouse gases in a way, by the things we use at home. Do you have some of these items in your house?

    It is very IMPORTANT that you turn off all electrical appliances when they are not in use. This is good practice, and you end up saving some money too.


    Everything humans have at home or workplace need power to work. This power comes from burning fossil fuels and other natural sources. The more fuels are burnt, the more CO2 are produced into the atmosphere.
    This means each time your dad drives his car, or you turn on an electric appliance, you are indirectly adding to the greenhouse gases in the atmosphere.

    This is not very good, as we are all contributing to global warming and climate change. This is a problem.
