GLOBAL WARMING  

            In   my article this time I will discuss about Global Warming.  Global warming is defined many experts that process, causes, impacts / consequences and how to overcome the most important thing in the study about global warming. We all know the impact is very harmful to the health of our planet and of course has implications for all the inhabitants of the earth. First of all let us discuss definition Global Warming. In General, Global Warming (Global Warming) are events increasing the average temperature in the layer of the atmosphere and Earth's surface.

         According to various studies, at this moment in Earth's surface temperature has shown a drastic increase of around 0.6 ° C, which occurred in the last century. Improvement and looks fairly small, but the impact of global warming are very big for the Earth and life on Earth. In symptoms or signs of global warming we can observe and feel. The symptoms of global warming is the turn of a difficult season we predicted, the frequent occurrence of a tornado, bleached reefs, and floods and droughts in the region of an unusual experience.

Many experts who express an opinion about the causes or factors of global warming. According to the experts that the Earth's surface warming due to increased greenhouse gases in the atmosphere that trap heat, not only that, there are many more causes of global warming need to be friends to know in repair and overcome it.

          There are many causes of global warming: the first is the model of a greenhouse. Greenhouse became one of the causes of global warming is a greenhouse where the model both in homes, buildings or places that use the concept of building glass can reflect light instead of absorbing air and sunlight. So that the impact of the glass umah concept is very influential on the increase and improvement of global warming on Earth.

           The second is Wastage in electricity consumption. Electricity is used by everyone, but many people are not aware of the savings on electricity usage. Various appeals have been widely driven or carried out, but in reality many people can not do. Pembororsan electricity still happens everywhere so that electrical waste could be one contributor to the increasing global warming.

The third is the use of fuel. Fuel used vehicles in addition to harm the health also gives the effect of the increase in global warming of the air pollution produced by each vehicle. The longer the number of users of automobiles and motorcycles more. It is thus the amount of air pollution that occurs even more.

          The fourth is the air pollution from Industrial and Factory. More and more industries and plant-growing, more and more global warming. Indeed the plus side, industry and factory can provide opportunities for the welfare of the people .Disisi downside losses smoke generated from the industry and very detrimental to acknowlege earth plant.

          The fifth is deforested rainforest. Many forest fires occurred illegally without permission from the government. In fact, many forest functions, one of which is to prevent flooding. Additionally, hutanpun can reduce heat in the earth's temperature is increasing. A source said that global warming increases by 50% the cause is CO2, or carbon dioxide. Where the carbon dioxide emissions caused by damage or forest fires. So deforestation has led to the increase in global warming of the earth.

          Many of the impacts resulting from the global warming, both positive and negative effects in a variety of fields. In the field of Agriculture: While CO2 is essential for plant growth, all agriculture also depends on a steady supply of water, and climate change tends to destroy supplies through floods and droughts. It has been suggested that higher latitudes - Siberia, for example - could be productive due to global warming, but the soil in the Arctic and adjacent territories is very poor, and the amount of sunlight that reaches the ground in the summer will not change because it is governed by the tilt of the earth. Agriculture can also be disturbed by forest fires and changes in seasonal periodicity, as is already happening, and the change of pasture and water supplies can affect cattle grazing and domestic prosperity. Increased warming may also have a greater effect on the countries where the climate is already near or at the limit temperatures which results in a reduction or crop failure - in the tropics or sub-Saharan Africa, for example.

         In the field of Health: warmer winters would mean fewer deaths, particularly among vulnerable groups such as the elderly. However, the same group is also vulnerable to additional heat, and deaths from the heat wave estimated to be about five times larger than the prevention of deaths in the winter. It is widely believed that a warmer climate will encourage migration spread of diseases caused by insects such as mosquitoes and malaria, which already appeared in places that have never been seen before.

            Impact on the Liquefaction Pole: While the opening of the Arctic ice-free year-round between the Atlantic and Pacific oceans will give some commercial benefit, is far outweighed by the negatives. Adverse effects include loss of polar bear habitat and increased movement of hazardous ice for shipping. The loss of ice albedo (reflection of heat), causing the ocean to absorb more heat, is also a positive feedback; warm waters increase glacier and Greenland ice cap melting, as well as increasing the temperature of the Arctic tundra, which then releases methane, a greenhouse gas that is very strong (methane is also released from the seabed, where it is trapped in ice crystals called clathrates). The melting of the Antarctic ice sheet is expected to further increase the sea level rise which no benefit is gained.

           impact of glacial melt Acidification: A matter of considerable concern, seems to be no benefit on the changing pH of the ocean. This process is caused by the increase of CO2 is absorbed in water, and may have a severely destabilizing effect on the entire food chain from melting glaciers samudra.Efek very detrimental to, the impact of the principle is that millions of people (one-sixth of the world population) rely on fresh water each persdiaan years from the melting of the natural springs and regrowth cycle and the water supply - drinking water, agriculture - the possibility of failure.

          Impacts on Sea Level Rise: Many low-lying parts of the world is to be greatly affected by rising sea simple. Rice fields flooded with salt water, which damage crops. Sea water polluting the river because it is mixed with fresh water upstream, and aquifers become polluted. Given that the IPCC does not enter the water from the melting of the Greenland and Antarctic ice caps due to uncertainty at that time, estimates of sea level rise is feared to be much underestimated the scale of the problem. No benefits are proposed for sea level rise

        Impact on the Environment: The positive effects of climate change could include green rain forests and enhancement of plant growth in the Amazon, increased vegetation in northern latitudes and the possibility of an increase in plankton biomass in some parts of the ocean. Negative responses may include further growth of oxygen-poor ocean zones, contamination or fresh water saturation, increase the natural fire events, the spread of vegetation that died because of the drought, the increased risk of coral extinction, global photoplankton decline, changes in migration patterns of birds and animals, change periodicity seasonal, food chain disruptions and species loss.

          Impact in Economics: The economic impact of climate change could be catastrophic, while there is only very little benefit. Stern report confirms the overall pattern of economic difficulties, and while a certain number can be contested, because the costs of climate change far outweigh the costs of prevention. Certain scenarios projected in the IPCC AR4 report would witness massive migration to countries flooded lowlands. Disruption of global trade, transport, energy supply and labor markets, banking and finance, investment and insurance, all would wreak havoc on the stability of both developed and developing countries. The market will survive the increased volatility and institutional investors such as pension funds and insurance companies will experience considerable difficulties.

         To reduce the effect of global warming which happened, you can try to do: First, choose the energy saving lamps as the lighting in your house. Energy saving lamps have more expensive than the general lamps, but the energy which is needed to light up is smaller than general lamps. Beside of that, this lamp is more durable.

        Second, do not forget to turn off the lamps when they were not in use again. When paying the bills, you will choose to pay online. This method is more econimal than pay directly. You can reduce the using paper which is used as noted invoice. You can save the fuels of your vehicles because you are not need to use your vehicles as when pay directly.

        Third, laptops and computer are the most things which is used in daily in every house. You should turn off this device when they are not in use too. And You can choose to do not use the screen saver to save the energy.

        Fourth, when shopping, you should bring your own bag which is made from the cloth. Avoid to use plastic bags which is given by the supermarket. Plastic is a material that is difficult to be processed naturally by the environment. It took hundred years to make it decomposed.

         Fifth, to have friendly environment, you can use bicycle which will good for your healthy too. In addition,  you must keep the condition of tap in your house in good condition.  From a lot of researches, broken taps can make the a lot of litter waters wasted in vain. Though, amount of the waters in the Earth is not much anymore. The last, always try to fill your courtyard with the trees. Tree can release oxygens which can make the air become fresh.
