人类活动对气候变化的影响（英文）

What role has human activity played in causing climate

change and what can be done to slow down its effects?

Climate change is a natural phenomenon, however, more and

more unreasonable human activity is speeding up climate

change. At the same time, nature seems to be punishing humans.

In recent years, more and more natural disasters have begun to

appear because of climate change, such as tornadoes, flooding

and increase of desert areas. Today, climate change has entered

a vicious circle and we must do everything we can to slow it down.

In this essay, I will show that human activity has played an

extremely important role in climate change. Firstly, this essay will

describe three main human activities that are speeding up

climate change, i.e. greenhouse gas emissions, population

growth and particulate matter emissions. After each problem I

will show some appropriate measures which have been taken to

slow down the effects of human activity.

Firstly, this essay will analyse greenhouse gas emissions. “At

the turn of this century scientists suggested that the carbon

dioxide added to the atmosphere from burning fossil fuels could

influence the global climate”(Carter, 2007, p70). Now, in order

to the social development can be fast, human use a large number

of fossil fuels. Large amount of greenhouse gas discharged

everyday because of fuel burning. Many factories release harmful

gases which can damage the atmosphere around the clock, such

as sulfur dioxide and chlorine. Thousands of cars release carbon

dioxide every minute in the world. These harmful gases and

carbon dioxide can lead to global warming, and break the rhythm

of climate change.

In recent years, the increasing greenhouse gases emissions

has attracted the attention of the government and scientist. At

the same time, climate change

research spending has been increased in many countries, for

example, “many billions of dollars have been expended by

major climate research groups on honing complex GCMs of the

ocean and atmosphere”(Carter, 2007, p70). Climate scientists try

to use the computer to simulate climate change and the

influence of greenhouse gases. Now, many countries have set up

a department to monitor the emissions of greenhouse gases.

Many countries have begun to eliminate or improve cars and

factories which can not reach the emissions standards. It is a

good way to reduce the greenhouse gases emissions.

The second reason lead to climate change is the growing

population. As we know, the population growth very fast.

Growing population need open up more living space and more

material sources, therefore, destroy the natural balance (Causes

of Climate changes, p3). Because of population growth, people

need more resources to maintain life, for example, people need

more wood for construction, and need for more land to live.

Therefore, humans cut down many trees and destroyed a lot of

forest. A large number of forest disappeared, desertification

become more and more serious, hot and cold cycle become

unbalanced, the difference in temperature between day and

night will become larger. Temperature cycle damaged will speed

up the climate change.

There are some solutions to these problems. Climate change

begin to faster, human should take some measures with climate

change. In some countries, there have some laws to limit the

population, and some governments make regulations about the

supply of energy under the constraints of minimizing climate

change (Bolin, 2007, p234). For instance, some laws limit the

people in the country can not have more than two children. I

think if we want to slow down the climate change, most of people

should pay enough attention to the environment protect.

However, in fact, many people do not care about climate change.

Therefore, governments should try all ways to make people kwon

the

importance of climate change. Through these useful laws

and regulations, the climate change will be slowed down.

Another reason for climate change is particulate matter

emissions. Human activities are more and more intense. Many

factories in the production process bring out a lot of dust.

“These sunlight-absorbing particles probably decrease albedo

over land, causing a warming; they also change stability of lower

atmosphere” (Kellogg and Schware, 1981, p33). Now, some

industrial cities polluted very serious. Because of the large

number of particulate matter emissions, the sky turned into gray,

more and more dust into the air. These particles reduce the

dissemination of heat and the flow of air. In the end, it will speed

up the global warming.

There are some solutions to these problems. Now, the

science is very developed, people can use some new technology

to improve the chemical industry emission standards, and as far

as possible to control particulate matter caused by heat radiation

(Kellogg and Schware, 1981, p33). By this way, the emission of

particulate matter will be reduced. In fact, there have some

factories have used the new filtration technology to filter the

gases from the production process. However, there still have a lot

of factories can not reach the emission standards. Therefore,

government should pay more attention to climate change, make

some laws to limit the factories emission standards.

In conclusion, climate change is still far from normal and it is

one of the main effects of many human activities. Many p

eople’s activities are still harmful to the climate. However, many

governments and people have begun paying attention to it. In

order to slow down the climate change from now, the

government should take practical and effective measures, such

as make laws about slowing down the climate change. Do not

indulge in empty talk. If

humans want a better living environment and better

development in the future, most people should begin to stop the

activities which are speeding up the climate change and help to

slow it down.
