GLOBAL WARMING: CAUSES AND REMEDY
In simple terms, global warming means an increase in the temperature of the earth and the changes in the weather. Result of this increase in the temperature of the earth. Changes in rainfall patterns, melting of glaciers and increasing sea level and the scary effects on flora and fauna can be revealed. At the level of common man does not understand how the global warming creates a big a problem in future. In the context of India, global warming is not a prevalent word and it has no meaning even for the Indians who are part of the race. But talking about the world of science, predictions are being made about global warming. It is being described as the biggest threat of the 21st century. This threat is believed to be greater than the third world war.
THE MAIN CAUSES OF GLOBAL WARMING
Green houses are the most responsible for climate change due to global warming. Green house gases are gases that absorb heat or heat coming from outside. Greenhouse gases are commonly used in extremely cold areas to keep those plants warm, which are defective in extreme cold weather. In such a situation, these plants are kept in a closed glass house and greenhouse gas is filled in the glass house. This gas absorbs the heat of the rays coming from the sun and keeps the plants warm. The same process happens to the Earth. Some amount of heat of the rays coming from the sun is absorbed by the earth. In this process, greenhouse gases circulating in our environment contribute significantly. If these gases did not exist in us, the temperature of the Earth would have been much lower than the current.
One of the most important hazardous gases in greenhouse gases is carbon dioxide, which we living animals emit with our breath. Environmental scientists say that the amount of carbon dioxide gas on the earth has increased continuously in the last few years. Scientists suggest a deep correlation between carbon dioxide emissions and temperature rise.
Green house gas is the gas that enters the earth’s atmosphere and becomes a factor in increasing the temperature. According to scientists, if the emission of these gases continues in this way, then in the 21st century, the temperature of the earth can rise from 3 ° to 8 ° C. If this happens, the consequences will be very fatal. In many parts of the world, the sheets of snow will melt; the sea level will rise by several feet. This behavior of the sea will submerge many parts of the world, causing great destruction.
EMISSION OF GREENHOUSE GASES
It is believed that due to emission of greenhouse gases moisture will increase in tropical deserts. Even in the plains, there will be such heat as never before in history. Due to this, various types of fatal diseases will arise. We have to keep in mind that we should not make nature destroy that, otherwise nature will destroy our existence. We have to take care of all these things.
The rate of pollution continues to increase in the same way; the average temperature of the earth will increase at the rate of 0.3 degrees Celsius per 10 years in the next two decades. Due to this increase in temperature, all the animals of the world will be disturbed and their life will be in danger. There will be a similar change in trees and plants. This will have the greatest impact on the population living around the ocean. Due to the rise in the water level, most of the cities situated on the sea coast will merge in these seas.
GLOBAL EMISSIONS BY ECONOMIC SECTOR
On the emission of global greenhouse gas, economic sector leads to the main role plays on the contribution to global warming.
- Electricity and Heat Production: On the first economic sector for the releasing greenhouse gas is Electricity and Heat Production. The causes are burning of coal, natural gas, oil for electricity and heat is the largest single source of global greenhouse gas emissions. In 2010, the contribution of Electricity and Heat Production is 25% in global greenhouse gas emission.
- Industry: No dough, the modern age of industry, they involve fossil fuels burned on site at facilities for energy. This sector also includes emissions from chemical, different hazardous mineral transformation processes. This hazardous material does not management properly. The contribution of Industry is 21% in global greenhouse gas emission.
- Agriculture & Forestry: Greenhouse gas emissions from this sector come mostly from agriculture and deforestation. The contribution of Agriculture and Forestry is 24% in global greenhouse gas emission.
- Transportation: Greenhouse gas emissions from this sector, primarily involve fossil fuels burned in road, rail, air, and marine transportation. This is universal facts that 95 % transportation is dependent on petroleum based fuels. The contribution of Transportation is 14% in global greenhouse gas emission.
- Buildings Material: Greenhouse gas emissions from this sector arise from an on-site energy generation and burning fuels for heat in buildings or cooking in homes. The contribution of Buildings Material is 6% in global greenhouse gas emission.
- Other Energy: In the position of this source of greenhouse gas emissions refers to all emissions from electricity or heat manufacture, such as fuel extraction, refining, processing, and transportation. The contribution of Other Energy is 10% in the global greenhouse gas release.
UNITED NATIONS ON GLOBAL WARMING DISCUSSION
Members of the United Nations have taken the first step to have a new climate treaty by 2015 and have started discussion aimed at reaching an agreement on how they will meet this goal. The treaty will be applicable to developed and developing countries.
The 195 countries, which have signed the United Nations Framework Convention on Climate Change (UNFCCC), have started a debate how to achieve the target set at the Durban conference in December. “Time is short and we have to take seriously the appeal of some of our brothers, especially countries with small islands,” he said, referring to the small countries facing the sinking crisis due to rising sea levels.
According to the conference held in the old capital of Germany, the new treaty will be completed by 2015 and will be implemented from 2020. At this, the poor and rich countries will be kept in the same legal framework to stop global warming and reduce the emission of toxic gases. UNFCCC only decided that it has to share a shared, but separate, responsibility. This means that poor and rich economies will be burdened differently. The issues that have to be decided by 2015 are how much the country will cut, what will be the structure of implementing the treaty, what will be its legal status.
MEASURES TO STOP GLOBAL WARMING
Scientists and environmentalists say that CFC is mainly used to reduce global warming. The emission of these gases has to be stopped and for this, the use of fries, air conditioners and other cooling machines will have to be reduced or machines which emit less released CFC gas.
The smoke emanating from the chimneys of industrial units is harmful and the carbon dioxide released from them increases the heat. Measures have to be taken to prevent pollution in these units. Environmental standards will have to be strictly followed to reduce the impact of smoke from vehicles. Efforts will have to be made to reuse waste from industries and especially chemical units and stop felling of trees on priority and emphasize conservation of forests.
Renewable energy measures have to be taken care of, that if wind power, solar energy and hydroelectricity are taken care of instead of electricity generated from coal, then control of gases heating the atmosphere can be found and at the same time there is no stopping of fire in the forests. Have to be applied.
