Global Warming   is the slow increase in the average temperature of the earth's atmosphere because an increased amount of energy striking the Earth from the Sun is being trapped in the atmosphere and not radiated out into space. The naturally occurring Greenhouse gases including carbon dioxide, methane, nitrous oxide and water vapour keep ground temperature at a global average of 15 degree Celsius. Without this natural blanket, Earth's surface would be about 30 degree Celsius colder than it is today, making the planet a freezing, barren, life less place. The Greenhouse gases keep the surface warm because as the incoming solar radiation strikes the Earth, the surface gives off infrared radiation that the gases temporarily trap and keep near ground level. But now, the Greenhouse gases are present in excess in the Earth's atmosphere due to human activities and thus trapping more heat and making the atmosphere more and more warm day by day. Since   the pre-industrial period, ...
