下面为大家整理一篇优秀的essay代写范文 -- Causes and consequences of global warming,文章讲述全球变暖是一种“自然现象”,是指地球大气层和海洋在此期间温度上升的现象。气候系统变化的原因很多,通常可以分为两类,即自然气候波动和人类活动的影响(Su Yue2008)。前者包括太阳辐射的变化和火山喷发。后者包括人类燃烧化石燃料和森林砍伐引起的大气中温室气体浓度的增加,硫酸盐气溶胶浓度的变化以及土地覆盖率的降低。因此,它导致近年来的一系列不良后果,并严重影响人们的正常生活,工作和学习。本文将从四个方面详细阐述我对全球变暖的理解,全球变暖的原因,温度升高的后果,未来的气候预测以及解决方案。

 

 

Causes and consequences of global warming

 

Abstract: global warming is a kind of "natural phenomenon", which refers to a phenomenon of temperature rise of the earth's atmosphere and ocean in the period. There are many reasons of the change of the climate system, which generally can be divided into two categories, i.e. natural climate fluctuation and the influence of human activity (Su Yue, 2008). The former one includes the change of solar radiation and volcanic eruptions. The latter one includes the increase of greenhouse gas concentrations in the atmosphere caused by human’s burn fossil fuels and deforestation, the change of sulphate aerosol concentration and the land coverage reduction. Consequently, it leads to a series of bad consequences in recent years and seriously influences people's normal life, work and study. This essay will elaborate on my understanding of global warming from the four aspects, the cause of global warming, the consequences of temperature rising, the future climate prediction and the solutions. 

 

Key words: climate change, causes of temperature rising, consequences of temperature rising, future climate prediction and present situation

 

 

 

 

The causes of global warming of human factors

First, factors of rapid increase of population

Dramatic increase of population this year is one of the main factors that cause global warming. At the same time, it also seriously threatens the balance between the natural ecological environments. With so many people, only their own emissions of carbon dioxide each year will be a staggering figure, for which it will directly result in increasing the content of carbon dioxide in the atmosphere. This form of carbon dioxide "greenhouse effect" will directly affect the earth's surface climate change.

The main reason which is generally acknowledged in the world today is the excessive greenhouse gas emissions that cause global temperatures rising. Human’s burning of coal, oil, natural gas, trees can produce large amounts of carbon dioxide and methane gases into the atmosphere, which consequently cause global heating, make the carbon cycle imbalanced and change the energy conversion forms of earth's biosphere. Since the industrial revolution, the global atmospheric carbon dioxide content has increased by 25%. It outreaches the historical records of all the past 160000 years that the scientists can survey and also has no sign of slowing (Lin Wenpeng, 2008).

Some scientists argue that the increase in carbon dioxide emissions in the atmosphere is the fundamental reason for global warming. According to a survey the international energy agency, the United States, China, Russia and Japan account for almost half of the total global carbon dioxide emissions. Research shows that the United States are the highest carbon dioxide emissions in the world, which about 20 tons of co2 emissions per capita, accounted for 23.7% of global emissions of carbon dioxide. China's annual per capita emissions of carbon dioxide, about 2.51 tons, accounts for about 13.6% of the global total.

Second, factors of atmospheric environmental pollution

At present, the global environmental pollution is increasingly serious, especially the rapid development of nowadays in most coastal cities, all kinds of plant coverage is more and more wide, tall chimneys every day with larger emissions into the air pollutants such as all kinds of dust, soot, particles emitted, serious air is beyond the scope of self-regulation, causes various to the ecological environment of early imbalance, such as in every region now has rendered haze weather is proof of that, at the same time due to the atmospheric pollution into the upper atmosphere, affect the normal ground reflection ability, will eventually lead to the whole of the ground temperature, causing a series of global warming. Now about global climate change research has clearly pointed out that since the end of last century had started to rise the temperature of the earth's surface.

Third, factors of land erosion, salinization, and desertification (Liu Benpei and Cai Yunlong, 2000)

It is known as the green plants in maintaining and regulating greenhouse gases in the atmosphere, carbon dioxide content is of great significance, for now, however, due to human activities to get wood win interests excessively cut down trees, cultivated land, and overgrazing and other factors lead to the global average worldwide have 20 hectares of forest are destroyed every minute, it will directly reduce the atmosphere through the plant photosynthesis is used to adjust the ability of carbon balance, leading to higher content of carbon dioxide in the atmosphere, eventually lead to global warming; At the same time there are 10 hectares of land desertification, the decline of the ground vegetation cover will lead to soil desertification;47000 tons of soil erosion, soil erosion of the soil fertility and water retention, thus reducing the biological productivity of the soil and its ability to maintain productivity, and can cause a wide range of floods and dust storms, causing great economic losses to the society, and the worsening ecological environment.

Forth, factors of acid rain harm

When it comes to the plunge in the forest coverage, cannot help but think that one is worse than being cut, that's a lot of acid rain erosion, at present, the bad effects of acid rain brings to the ecological environment has got the attention of whole range, on the one hand, if a place of rainwater acidity is too strong, will not only harm to rivers and lakes, and will lead to that a whole area of forest was broken, it also indirectly makes the global temperatures rise. The fundamental source of acid rain is still a great deal of coal, oil burning, caused by the content of sulfur dioxide in the air on the high side.

Fifth, factors of toxic waste pollution

Factory emissions of toxic waste gas, waste residue, waste water, into the land, atmosphere, hydrosphere, would cause a normal proportion of gases in the atmosphere, make air adjustment, eventually leading to a series of other meteorological disasters, serious damage to the ecological environment; Toxic waste residue after the infiltration of surface, serious damage to the normal soil composition proportion, causing soil salinization, is not suitable for the normal growth of vegetation, crops, resulting in ecological imbalances, atmospheric imbalances and played a negative effect on global climate change; The wastewater, especially toxic waste water discharged into the rivers and lakes, the harmful aquatic organisms and plant normal growth of normal growth, affect the normal ecological balance.

 

The consequences of global warming

First, sea level rise

Sea level rise is the biggest influence to the coastal city and the islands. By some estimates, over the past century along with the global climate increases the waist is 0.6 ℃, the global sea level rose by about 10-15 cm. Some scholars believe that global temperatures could rise by 1.5 to the next century, 4 ℃, the sea level rise 0.8 1.8 cm. If so, most of Manila in the Philippines may reside in 1 m deep underwater, 3.3 million residents to evacuate the city and Jakarta, Indonesia.

Second, climate change

In most of the temperature rise, the global rainfall increases, typhoons, hurricanes are more frequent and more powerful. Scientists predicted that if the temperature rise in the tropics 2-3 ℃, the sea surface temperature rise will cause the typhoon increased energy, and to develop in the high latitudes, especially heavy rains brought by the typhoons, hurricanes and other disasters, will lead to debris flows, landslides, etc, a serious threat to the safety of traffic and living.

Third, the influence for all man kinds

The earth warming makes abnormal climate changeful, flood drought increased, causing crop failures, plant diseases and insect pests of popular, and lack of water resources. Temperature rise at the same time, the impact to human physiology, human sick risk is more and more big, and the various physiological diseases will spread quickly, and even breed new diseases. Eye disease, heart disease, respiratory system diseases,

Digestive system diseases, viral diseases, bacterial diseases on health care to choose a suitable text book people society paid money will be more and more, dead people will be more and more. Cancer, will more and more popular, sudden death, will be more and more common. No amount of money, it is a good doctor, also not necessarily can save your life.

Conclusion

Human activity causing a sharp increase of the concentration of greenhouse gases in the atmosphere and the cause of global climate change obviously, has become the main and the most direct change in the globe, and has important influence on all aspects of human society. The greenhouse effect problem has been ranked top in global problems, whose great harm has spread all over the world. The task of how to prevent global warming has been placed in front of our humans today. With the continuous development of science and technology (China Environmental Press, 2005), people will have a more clear understanding of the changes in concentrations of greenhouse gases and the relationship of the climate change. As long as we work together with common concern for the earth and initiative research of new measures to control the greenhouse effect, the global warming problem can be solved.
