Global Warming
Global warming means increases in the average temperature of Earth's atmosphere and oceans. About 90% of it is caused by increasing concentrations of green house gases produced by human activities such as Deforestation and burning of fossil fuels. These green house gases: CarbonDioxide, Methane,Nitrogen Oxide and other causes increase in warming of earth's temperature. An increasein global temperature will effect sea levels to rise, Hurricanes and other storms are likely to become stronger, floods and droughts will become more common, scarcity of fresh water will prevail, many diseases will spread and ecosystems will change all theses destructions will cause disorder in the world.

There are certain causes which heavily impact on our earth and rises in temperature. The Global Warming and Green House Gases are correspond to each other.

Green house gases are made of human activities. Human beings creates the emission of green house gases. The primary gas is carbon dioxide which is released every time in the atmosphere, mainly from fossil fuels tha most significant cause of Global warming.

Carbon dioxide is released: burning of something, it be a car, an areoplane or a coal plant. The other cause of releasing carbon dioxide is Deforestation. This increases the severity of global warning. It is released from the human conversion of forests and grass lands into farm lands and cities. All living plants store Carbon. when those plants die and decay, carbon dioxide is released back in the atmosphere.

The other green house gas is Methane. It is 100 times as powerful as carbondioxide. Methane is created when bacteria break down organic matter under oxygen starved conditions. This occurs when organic matter is trapped under water, as in rice paddies. It also takes place in the intestine of herbivores animals such as cows, sheep and goats. The other form of methane is Clatherates. These are frozen chunks of ice and methane that rests at the bottom of the world's oceans. As the water warms the ice melts and the methane is released.

Besides that, Nitrogen oxide is also a powerful green house gas. The GREEN REVOLUTION of teh twentieth century has allowed the farmers of the world to use chemical fertilizers and machines to produce for more food than they ever did. One of the primary components of the green revolution has been the development of nitrogen fertilizers that dramatically accelerates the growth and productivity of plants in the field. This green revolution technologies have become so popular that humans are now adding more nitrogen to the earth. Nitrogen oxides have 300 times more heat trapping capacity per unit of volume than carbon dioxide has.

REFF: A recent United Nation Food and Agriculture Organization study found that modern farming is contributing more to global warming than all of the transportation sector combined.

from above all green house gases there are few other but strong gases such as cholorofloro carbons and hydrochloro-floro carbons that are used in refrigeration. These gases occur in lower concentration in the atmosphere, but also causes global warming.

All these gases occur in the atmosphere whose effects are horrible and even wiped out entire planet. The major effects of global warming are increasing global temperatures, rises sea level. Ice is melting world wide, especially at earth's poles. This includes mountain glaciers, ice sheets covering west Antarctica and green land, Arctic sea ice. These land countries would come under ocean water and will be erased from the map of the world.
