Global Warming, aside from pollution is one of scientists biggest concerns. The green house effect is one of the major reasons causing Global Warming. There are four steps in the Greenhouse effect, which are, Sunlight radiates from the sun, through space, to earth's atmosphere. The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets impregnated by enclosing air and land, which in turn makes it warm. Infrared rays that are remitted into the atmosphere are captured by greenhouse gases. The gas then absorbs the light and is remitted back to the Earth's surface and warms it even more. Methane and carbon dioxide are some of the naturally occurring greenhouse gases. This is the manner in which the Earth keeps itself temperate enough for humans to live on it. The only concern with this is that humans are enhancing the process even further.
