Greenhouse gases is a number of gases that cause the greenhouse effect, which is biased to absorb and reflect radiation emitted wave earth. As a result, the heat will be stored in the earth's surface. This happens over and over and result in an average temperature of the earth continues to increase yearly.
However, that greenhouse gases are gases in the atmosphere is very important to maintain the temperature of the earth. The dominant one is CO2. Without Grk, planet Earth could be too cold and the earth into a place that can not be inhabited. Besides CO2, which is classified N2O (dinitrosida), CH4 (methane), SF6 (sulfurheksaflorida), PFCs (perflorokarbon) and HFCs (hidroflorokarbon).
The greenhouse effect caused by greenhouse gases have global warming or the index is also the potential for greenhouse gas warming. The value of different indices, such as the effectiveness of N2O in the heat absorbing approximately 310 times greater than CO2 and CH4 in the effectiveness of the heat absorbing approximately 21 times greater than CO2. Although CO2 has a warming potential of the smallest, but because of their concentration in the atmosphere compared to most greenhouse gases other, approximately 55%, instead of CO2 was rumored as a major cause of global warming.

As a source of emissions (sources) of greenhouse gases are exhaust gases from burning fossil fuels, eg coal, fuel, biomass, gas, and so on. Likewise, the industrial processes such as cement industry, steel, petrochemicals, and so on. Besides also caused by the destruction of forests, changing land use, agricultural land, flood, manure, garbage, coal mining and so on.
Efforts can be done to reduce the emission of CO2 is a form of cooperation between countries to reduce emissions of view how the arrest CO2. For example, construction of CO2 capture by the Mitsubishi company in Malaysia that can capture CO2 to 200 tons per day of liquid CO2. Furthermore, this liquid CO2 can be used for drinks industry could or injection into the sea. But if a gas, the CO2 gas is injected into the ground to force oil or methane to the surface, or stored in the soil as a salt.
CO2 gas after being caught than injected into the soil can also be compressed into liquid CO2 to be included next to the sea. This could impact will increase the acidity (H + ions) in seawater. But not to worry because sea water is alkaline (pH more than 7).
Another effort is the use of fossil energy savings or to replace fossil energy consumption with environmentally friendly energy such as nuclear energy for power generation, solar energy for motor vehicles. Also bare afforestation, reforestation in various cities and so on.
