ALL events on earth have origins, not least the occurrence of climate change on earth. The origin or cause and effect of climate change can simply be done by tracing the stages until the occurrence of such changes. The first stage begins with the increasing amount of greenhouse gases in our skies, green house gases which include water vapor, carbon dioxide, methane, nitrogen oxide and other gases. Greenhouse gases are gases that exist in the atmosphere that cause the greenhouse effect. These gases actually appear naturally in the environment, but can also arise due to human activities. Water vapor is a greenhouse gas that arises naturally and is responsible for most of the greenhouse effect, which is the event where the Earth's surface absorbs some heat and reflect back the rest. The amount of water vapor change regionally, and human activity does not directly affect water vapor concentrations except at local scales. Without realizing it, human activity triggers an increase in the amount of carbon dioxide released into the air. For example, when humans burn fossil fuels, solid waste, used wood to heat buildings, moving vehicles, and generate electricity. In fact, the number of trees which absorb carbon dioxide decreases due to encroachment of forest for timber and taken to the expansion of agricultural land. Although the oceans and other natural processes to reduce carbon dioxide in the atmosphere, but it quickly loses its ability to human activity. Just for example, in 1750 there are 281 carbon dioxide molecules in one million molecules of air or about 281 ppm. The number then rose to 383 parts per million in January 2007, an increase of 36 percent. Gas triggers another greenhouse effect is methane. He was able to capture 20 times more heat than carbon dioxide. Methane is released during production and transportation of coal, natural gas, and petroleum. Methane is also produced from the decay of organic waste in landfills (landfill), it can even remove it by certain animals, like cows. Since the beginning of the industrial revolution in the mid-1700s, the amount of methane in the atmosphere has increased by one-half times. Nitrogen oxides produced from burning fossil fuels and by agricultural land. Nitrogen oxides can capture 300 times more heat than carbon dioxide. The concentration of this gas has increased 16 percent when compared to the period before the start of industrialization. Other greenhouse gases generated from various manufacturing processes. Mixtures were flourinasi dihasilan from aluminum smelting. Hydrofluorocarbons (HCFC-22) formed during the manufacture of various products, including foam for insulation, furniture (furniture), and seating in the vehicle. Refrigerator in some developing countries still use chlorofluorocarbon (CFC) as a cooling medium, capable of retaining heat than the atmosphere also reduces the ozone layer (the layer that protects Earth from ultraviolet radiation.) During the 20th century, these gases have been accumulating in the atmosphere, but since 1995, to follow the rules set forth in the Montreal Protocol on substances depleting the Ozone Layer, the concentration of these gases start getting a little released into the air. In 2000 the scientists identified a new material which increased significantly in the atmosphere. Such materials are trifluoromethyl sulfur pentafluorida. Gas is still relatively rare because the producing sources unidentified. But the scientists found the amount of gas is increasing very fast. The danger, is able to capture the hot gas is much greater than the greenhouse gases that have been known previously. Global Warming Greenhouse gases that accumulate in the air to the onset of climate change. Slowly, this gas will be a trigger factor, what we know as global warming. This event is influenced by the increase in atmospheric temperature or temperature, alut, and the earth's land. The process of global warming can be explained in a simple, ie, the heat absorbed some rest and reflect back to earth. Some of this heat wave infrared radiation containing long into outer space. However, some heat remains trapped in Earth's atmosphere due to accumulated amount of greenhouse gases include water vapor, carbon dioxide, and methane. These gases absorb and reflect back the radiation waves emitted by the earth, the result will be stored heat in the earth's surface. This happens repeatedly and result in annual average temperature of the earth continues to rise. If the concentration of these gases continue to rise in the atmosphere, the more heat is reflected to the earth. Actually, this greenhouse effect is needed by living things on earth. Without the greenhouse effect, the planet will be very cold to minus 18 degrees Celsius until the ice would cover the entire surface of the earth. However, karen amount of greenhouse gases emissions in the atmosphere has been excessive, then there was global warming. So far the issue of climate change and its impact based on the report scientists who are members of the Intergovernmental Panel on Climate Change (IPCC) or the intergovernmental panel on climate change. This panel was established in 1988 by United Nations organizations, the World Meteorological Organization (WMO) and United Nations Environment Programme (UNEP). The goal is to evaluate the risks of climate change due to human activities, by examining all aspects of technical and scientific literature based. One of the important conclusions of the panel is the change in rapidly changing climate due to human activity, have occurred since the mid-20th century. IPCC Report 2001, for example, states that the earth's air temperature has risen 0.6 degrees Celsius since 1861. They also predict an increase Earth's average temperature increased from 1.1 to 6.4 degrees Celsius until 2100. Source Emission of Global Warming Institutions that care about the issue of climate change called the United States, China, Indonesia, Brazil, Russia, and India is the world's largest greenhouse gas producer in the world. Each contributed 6005, 5017, 3014, 2316, 1745, and 1577 million tons of carbon dioxide equivalent (MtCO2e). Sources of these emissions come from energy sector, agriculture, forestry, and waste. The energy sector is the largest emitter of greenhouse gases MtCO2e 12,628, followed by 4479 MtCO2e forestry sector, the agricultural sector MtCO2e 2912, and from garbage at 635 MtCO2e. The total greenhouse gas produced four sectors reached 20,654 donated MtCO2e country. Meanwhile, the forestry sector was ranked second contributor to greenhouse gas emissions by 4479 MtCO2e. Emissions resulting from deforestation and land conversion. Contributor to these emissions come from countries that have ample forest cover, namely Indonesia and Brazil. Each MtCO2e 2563 and 1372. China dominated the agricultural sector emissions, by 1171 MtCO2e followed by Brazil and India. Meanwhile, greenhouse gas emissions come from waste largely dominated by the United States, China, and India. In early 1896, the scientists make a hypothesis or provisional estimates that burning fossil fuels will change the composition of the atmosphere and to increase global average temperatures. This hypothesis was proven in 1957 when researchers working on global research program of the International Geophysical Year, took samples of the atmosphere from the top of Mauna Loa mountain in Hawaii. The measurement results show an increase in the concentration of carbon dioxide in the atmosphere. After that, the composition of the atmosphere continues to be measured carefully. The data collected indicate that indeed an increase in the concentration of greenhouse gases in the atmosphere. Initially, scientists could only guess the global climate warms up, but they are not able to provide appropriate evidence. Temperatures continue to vary from time to time and location. They came to observe the climate for years to obtain clear data. Until the late 1980s, observations show this warming trend, but statistical data is still not reliable. Weather station at the beginning, is located close to urban areas so that the temperature measurement will be influenced by the heat emitted by buildings and vehicles and also heat stored by the building and road materials. Since 1957, the data obtained from a reliable weather station (located far from urban areas), and from satellites. These data provide a more accurate measurement, especially at 70 percent of the planet's surface covered with oceans. Data that more accurately shows that the warming trend the earth's surface actually occurs. In the late 20th century, during the last hundred years the warmest conditions occurred after 1980. The three hottest years occurred after 1990, and the warmest conditions occurred after 1998. The IPCC predicts gas concentrations in the atmosphere has not increased since 2100. However, they warn climate continues to warm stay during certain periods due to emissions that have been released previously. Carbon dioxide remains in the atmosphere for a hundred years or more before nature can absorb it again. If greenhouse gas emissions continue to increase, experts predict, karbondioksioda concentration in the atmosphere can be increased up to three times at the beginning of the century 22. As a result, there will be dramatic climate change. Although the actual events of this climate change has occurred several times throughout Earth's history. Humans will face this problem with the risk of a very large population, and this incident will be more horrible.
