Green House Effect
The greenhouse effect being a natural phenomenon is directly affected by human activities such as new industrial processes, more extensive agriculture and a rapid increase in the world's population causing global warming. Greenhouse effect is like a “double jeopardy”. Without the natural greenhouse effect we would be living in a very chilly place – the world’s average temperature would be minus 18 degree Celsius instead of 16 degree Celsius we are used to. Again, greenhouse effect, influenced by the careless human activities, is the reason of recent increase of average temperature of the earth, popularly known as global warming. The natural greenhouse effect is a phenomenon created by the heat energy radiated by the sun and greenhouse gases (water vapor, carbon dioxide, methane, nitrous oxide and halocarbons) normally present in the atmosphere. Sunlight passes through the atmosphere, warming the Earth; in turn, the Earth radiates this energy back towards space. As sun’s energy passes through the atmosphere, greenhouse gases absorb part of the energy, while the remainder escapes into space. This means that some of the sun's energy becomes trapped – thus making the lower part of the atmosphere, the Earth, warmer. Now, if t
