GREENHOUSE EFFECT

Greenhouse effect is a phenomenon where the sun radiation short wave penetrate atmosphere and become long wave when reaching surface of earth. After reached surface of earth, partly waving the bounced to return to atmosphere. But not all wave which the bounced discharged to outer space. Partly long waves re-bounced by glasshouses gas coats in atmospheres to surface of earths. Gas glasshouse is gas in atmospheres having ability for permeated the suns radiation has bounced by earths so the earth become progressively hot.

It self greenhouse effect happened because the rising concentration of gas CO2 (carbon dioxide) and other gas like sulphur dioxide ( SO2), oxide nitrogen ( NO), dioxide nitrogen ( NO2), methane gas ( CH4), chlorofluorocarbon CFC) in atmosphere. Increase concentration of CO2 itself because of increase of various combustions types on the surface of earths like combustion of oil fuels (BBM), stone smouldered, and other organic component which abysmall ability of surface of earths to the absorbtion. Materials on the surface of earth which active sharing for absorbtion results combustion were flora, forest, and sea. So comprehensibility if forest progressively hairless, hence heat on the surface of earth will go up
The cause of greenhouse effect naturally because of sunshine radiation . when sunshine radiation step into earth, this radiation in form of short wave radiation and penetrate atmosphere coat then 10% radiant energy permeated by surface of earth, 30% bounced by surface of earth,40% applied for heating earth,19,97 % to evaporate water and only 0.03% exploited by plant for photosynthesis. At the time) of sunshine radiation bounced by surface of cloud and earth, this radiation in form of long wave radiation or called as also infrared but this radiation partly have no to penetrate returning atmospheres coat because arrested by glasshouses gas in atmosphere so that this radiations snared in earths in the form of hot energies. This things causing greenhouse effect happened, but generated by greenhouse effect is sunshine radiation still not yet is dangerous. Besides sunshine radiation , natural factor cause of greenhouse effect is the many happened mount disaster erupt, when mount erupt, much gas co2 spent by the mounts. Where this gas including gas which potency cause greenhouse effect .
Besides natural factor there are also factor which because of act of man that is deforestation wildly, combustion of forest, usage of oil or fossil fuel at motor vehicle and industrial, exploiting of fertilizer, deterioration of agriculture pickings and deterioration of dirt of live stocks
Deforestation give big influence to greenhouse effect because forest function to change CO2 become O2.if many deforestations so CO2 atmospheres coats increase not only deforestations, combustion of forest for opening farm for agriculture and usage of fossil or oil fuel also have role in increasing rate CO2 in atmosphere because result from process combustion of forest and usage of earth oil fuel is CO2 gas. in sector agriculture, fertilisier use, deterioration of agriculture pickings and deterioration of dirt of live stocks can yield methane gas ( CH4).
Survey result tell is two impact available for generated by greenhouse effect, that are:
Impact to nature.
1. The rising of sea surface, This thing happened because liquid ice and glasier in pole. The rising of sea surface will cause big flood . In the year 2100 approximating sea water will be rise until 15-95 cm.
2. Growing of forest fire, because impact of weather which more the more hot.
3. The rising of sea-water temperature so cause broken of coral and all ecosystem which in there.
4 The increasing of frequency and rainstorm intensity, hurricane, and floods
Impact to human health.
1.The distribute of tropical disease, like malaria, to new areas because increasing of mosquitoes and insects
2. Extreme temperature will cause the virus have live long time
3 Increase of temperature of 1oC cause the rising of mortality become 300.000 each year impact malaria, malnutrition and diarrhoea ( WHO; 2005 )




In this time there is two methods to surpass problem of greenhouse effect that:
1.Adaptation
That is prepare own and live with various change of effects change of the weather, good which happened and also anticipated impact which possibly happened. this thing can be done with make system forewarning in assessed by area is storm gristle and also giving guide about what must be done public if when storm happened. beside that, make protection for public who live in coastal area with method to plant mangrove forest. Existence of mangrove forest lessen possibility of coastal erosion and sea-water instruction into source of cleanness water as impact of the rising of sea surface .Reboitation is very important in to surpassse greenhouse effect.
2. Mitigation
Mitigation is method for overcoming greenhouse effect by lessening emission glass house glass man activity result. This can be done by using fuel from cleaner energy source, like changing over from coal to gas, or use newest energy source like biomass or solar energy. Besides, lessen fuel consumption for motor vehicle and economize electrics also lessen emission glass house gas
