The natural 'Green-house Effect' is essential for life on earth. Various gases in the atmosphere like water vapour and carbon dioxide trap some of the outgoing radiation from the earth, retain the heat and keep the earth's temperature at levels where living things, including man, can su..

Harmful results of Greenhouse Effect is global warming. While the green house gases enable life to exist, problems arise when the atmospheric concentrations of these gases increase. All climate changes up to the industrial revolution occurred naturally as very few gas..

The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back into the space. How..
