The greenhouse effect

The cause of global warming
[edit] The greenhouse effect
Any source of energy contained in the Earth comes from the sun. Most of the energy in the form of short-wave radiation, including visible light. When it reached the surface energy of the Earth, he changed from light into heat that warms the Earth. Earth's surface, will absorb some heat and reflecting back the rest. Some of this heat radiation form of long wave infrared to space. However, some heat remains trapped in the Earth's atmosphere due to accumulated amount of greenhouse gases include water vapor, carbon dioxide, and methane which trap the waves of this radiation. These gases absorb and reflect radiation waves emitted heat the Earth and consequently will be stored in the Earth's surface. This occurs continuously resulting in an average temperature of the earth continues to increase yearly.

These gases working in greenhouse gases. With the increasing concentration of these gases in the atmosphere, the more heat is trapped below.

This greenhouse effect is needed by all living things on earth, because without it, this planet will become very cold. With an average temperature of 15 ° C (59 ° F), the earth actually has more hot 33 ° C (59 ° F) from the original temperature, if there is no greenhouse effect the earth temperature is only -18 ° C and ice would cover the entire Earth's surface. On the other hand, if these gases in the atmosphere has been excessive, will cause global warming.
