Dear steemit friend's
Carbon dioxide: Carbon dioxide is the most important gas in the greenhouse gases, which is usually emitted by the burning of fossil fuels. In the atmosphere, this gas is growing at 0.5 percent per annum and its capacity is .
Burning of bio-fuels involves more than 5 billion tonnes of carbon dioxide per year in the atmosphere, which accounts for more than 90 percent of North and Central America, Asia, Europe and Central Asian republics. Compared to pre-industrialization times, the level of carbon dioxide in the air has increased by 31 percent today. Since forests are the main absorbers of carbon dioxide, the deforestation is also a major cause of the continuous increase in the atmosphere of this gas.
Forest destruction is responsible for 20% of carbon dioxide engagement in the environment. As a result of forest-destruction, approximately 120 billion tonnes of carbon dioxide is associated with the environment between 1850 and 1950. In the last 100 years, the carbon dioxide environment has increased by 20 percent.
The amount of carbon dioxide between 1880 and 1890 was approximately 290ppm (million of parts), its volume was 315 ppm in the year 1980, 340 ppm in 1990 and 400 ppm in 2000. There is a possibility that by the year 2040, the concentration of this gas in the atmosphere will increase to 450 ppm. The contribution of 55% to the global pancreas of carbon dioxide is contributed. Industrialized developed countries are more responsible for the increase in carbon dioxide in the environment.
Methane Gas: Methane is also a very important greenhouse gas which is increasing in the environment at the rate of 1 percent per annum. The potency of methane is 36. This gas is 20 times more effective than carbon dioxide. In the last 100 years, methane has increased twice in the atmosphere. Paddy fields, marsh land and other types of moist soil are the main sources of methane gas emissions.
According to an estimate, 20 percent of methane growth in the environment is due to paddy cultivation and 6 percent coal mining. In addition, internal fermentation in the herbivorous animals and termites is also a source of methane emissions. In the year 1750, the amount of methane increased by 150 percent. According to an estimate, by 2050, methane will be a major greenhouse gas. This gas contributes 20 percent to global tapping. Developing countries are more responsible for methane emissions than developed countries.
Chlorofluorocarbons: Chlorofluorocarbons chemicals are also responsible for the greenhouse effect. The use of chlorofluorocarbons chemicals is usually in the form of refrigerant, catalyst and solid plastic foil. The chemicals in this group are quite permanent in the environment and it is of two types - Hydro fluoro carbon and fluoro carbon on it. The growth rate of hydro fluoro carbon in the environment is 0.4 percent per annum and its tubing capacity is 14600. But the annual growth rate of fluoro carbon is 0.4 percent per annum, while its caliber capacity is 17000.
Hydro fluorine is contributed by 6 percent in carbon dioxide, while fluoro carbon contributes 12 percent to global panic. Due to industrialization, the atmosphere of chlorofluorocarbons has increased by 25 percent. Therefore, industrialized developed countries are more responsible for the excretion of chlorofluorocarbons compared to developing countries.
Nitrous oxide: Nitrous oxide gas is increasing at the rate of 0.3 percent per annum and its capacity is 140. Incident use of biofuels, fossil fuels and chemical fertilizers in agriculture is a major factor in its emissions. Nitrous oxide is formed as a result of the reaction of microorganisms to the chemical fertilizers in the soil, and then it is excreted in the gas environment.
For the growth of this gas in the atmosphere, fossil fuels are responsible for 70 to 80 percent of chemical fertilizers and 20 to 30 percent of fossil fuels. This gas contributes 5 percent to global tapping. Nitrous oxide is also responsible for the erosion of the stratospheric ozone bar. Ozone strip erosion will also increase global tapping.
Ozone: The tropospheric ozone is also an important greenhouse gas that is growing at the rate of 0.5 percent per annum in the atmosphere. The gas capacity of this gas is 430. Generation of ozone is usually in the reaction of nitrogen dioxide and hydrocarbons in the presence of sunlight. Global tapping of ozone gas contributes 2 percent.
Emissions of greenhouse gases globally:>
As far as emissions of greenhouse gases are concerned, at global level, India exits only 1.2 tonnes per person per year: green house gases. Whereas the United States exceeds 20 tons of greenhouse gases per person per year. Russia 11.71 tonnes, Japan 9.87, EU 9.4 and China 3.6 per person per year emits greenhouse gases.
Therefore, compared to the developing countries, the developed countries emit more of greenhouse gas emissions, which will suffer from other developing countries of the world including India.
