CLIMATE CHANGE AND GLOBAL WARMING

Climate change

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

The green house effect

While other planets in Earth's solar system are either scorching hot or bitterly old, Earth's surface has relatively mild, stable temperatures. Earth enjoys these temperatures because of its atmosphere, which is the thin layer of gases that cloak and protect the planet. However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Consequences of global warming

There are two major effects of global warming: the increase of temperature on the earth by about 30 to 50C (5.40 to 90Fahrenheit) by the year 2100 are Rise of sea levels by at least 25 meters (82 feet) by the year 2100. Other consequences are listed below:

• Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.

• Amounts and patterns of precipitation are changing.

• The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.

• Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts heat waves, and tornadoes.

• Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.

• Diseases like malaria are returning into areas where they have been extinguished earlier

Tham khảoOne of the factors in global warming is carbon monoxide. The more carbon monoxide in the atmosphere, the less the atmosphere is able to clean itself. The result is a warming of the atmosphere, the so-called global warming, and possibly ozone damage.Earlier, it was found that carbon monoxide was concentrated in the Southern Hemisphere, and could be attributed to deforestation. Huge areas of forest and grasslands in South America and Africa have been burned, putting carbon monoxide into the atmosphere. Recently, however, the Southern Hemisphere has been found to be clean, while the Northern Hemisphere is more polluted than expected.The latest research was done during the northern winter. The high levels in the Northern Hemisphere could be because of this. In winter, carbon monoxide is destroyed more slowly. There are also more fires burned in winter, and possibly industrial processes work harder. It could also reﬂect the ever-increasing number of cars on the roads. Optimists hope that the reason why the North has overtaken the South as the major area of carbon monoxide is that at last the burning has stopped, or at least slowed down.

The costs and benefits of global warming will vary greatly from area to area. For moderate climate change, the balance can be difficult to assess. But the larger the change in climate is, the more negative the consequences will become. Global warming will probably make life harder, not easier, for most people. This is mainly because we have already built enormous infrastructure based on the climate we now have.

People in some temperate zones may benefit from milder winters, more abundant rainfall, and expanding crop production zones. But people in other areas will suffer from increased heat waves, coastal erosion, rising sea level, more erratic rainfall, and droughts.

The crops, natural vegetation, and domesticated and wild animals (including seafood) that sustain people in a given area may be unable to adapt to local or regional changes in climate. The ranges of diseases and insect pests that are limited by temperature may expand, if other environmental conditions are also favorable.

In its summary report on the impacts of climate change, the Intergovernmental Panel on Climate Change stated, “Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.”

1. What is the main idea of the passage?

A. Environment pollution is real. B. Reasons why low-lying areas are flooded.

C. Solutions to global warming. D. Reasons why global warming is a problem. 1…….

2. In paragraph 1, the word ‘This’ refers to _____.

A. harder life as a result of global warming B. easier life as a result of global warming

C. climate change on global scale D. flood in low-lying areas

3. In paragraph 2, the word ‘erratic’ is closest in meaning to _____.

A. predictable B. unpredictable C. flexible D. inflexible

4. According to the passage, all of the following are the results of global warming EXCEPT _______.

A. higher temperature B. coastal erosion C. stable rainfall D. increasing sea level

5. What may happen to diseases and insect pests as a result of global warming?

A. They will become extinct. B. They will increase in number.

C. They will not harm our planet. D. They will be under good control.

I. Read and answer the questions

Air pollution

We are nowadays becoming more aware of pollution matters that affect dramatically our lives; especially there is growing concern about air pollution. There are some reasons that lead to this kind of pollution. Firstly, the development of industrial zones, factories and building construction areas is producing a large amount of dust and poisonous air. Especially in the developing countries, people rarely pay their attention to the air treatment process that make the air pollution condition even worse. Secondly, because of the increasing unrbanization, it can be easily seen that there is always a lot of traffic in rush hour and dust one the road these days. The smoke from vehicles and manufacturing exhaust increase the amount of carbon dioxide in the air which makes us feel really hard to breathe. The consequences are very bed. Smog and dust can do serious harm to our health and especially our lungs. We have thousands of asthma and adult respiration distress cases each year which raise concern about the air quality. Moreover, acid rains are becomning more and more popular which damage crops and fields. Many people believe that air pollution is also causing global warming and it is difficult to improve the air without the efforts of all countries around the world.

1. According to the passage, where does a large amount of dust and poisonous air come from?

..........................................................................................................................................................

2. Do developing countries take the air treatment process into carful consideration?

..........................................................................................................................................................

3. Why is it difficult for us to breathe when traveling on the roads or streets?

..........................................................................................................................................................

4. What does the word “urbanization” mean?

..........................................................................................................................................................

5. Which particular part of our body is seriously affected by smog and dust?

..........................................................................................................................................................

6. Is it written in the passage that there are milions of cases related to breathing anually?

..........................................................................................................................................................

7. What is the hramful effect of acid rains?

..........................................................................................................................................................

8. According to the passage, if all countries in the world ignore the air pollution condition, will it easy to make the air fresher?
