IMPROVEMENT green house effect

atmospheric temperature changes are generally associated with several factors such as changes in activity of the Sun, or the pattern of rotation of the Earth. However, most scientists believe that global warming is caused mainly by the greenhouse effect. This effect occurs when the bulk of the energy from the sun reaching the Earth kepermukaan not reflected back out into space, malaah otmosfera earth system fails to function properly.

As we find, according to the Wien law, the nature of radiation from an object depends on its temperature. The sun have a surface temperature of 6000 degrees, glowing in the waves seemed terutamamya which is simply the energy in our atmosphere. However, due to Earth's temperature is much lower than the temperature of the Sun, the planet we draw out the energy in the form of infrared radiation. Gases such as carbon-dioxide, methane and nitrous oxide, which is also transparent in the visible wavelength, is opaque in the infrared radiation. Their characteristics are preventing workers from out of the last keangkasa. They absorb the energy to make our atmosphere warm. Most of the solar energy is absorbed by the lower atmosphere, as happened on Venus.

It is probable that the greenhouse effect and global warming, which is accelerating since the 19th century, due to the impact of human activities on the environment. Most of the gas which has the characteristics of the greenhouse effect has been released into the atmosphere through the activities of the modern use of fossil fuels in industry and transport. It can also be caused by certain agricultural activities such as cattle. We expected that carbon-dioxide has increased by 30 percent since the beginning of industrial era, which is a major contribution to aggravate the greenhouse effect.
