Concerns about the Greenhouse Effect Read Answer 20

1 The following understanding of the concept of "greenhouse effect" is accurate ( ).

a Refers to a thermal insulation effect that occurs in a certain confined space that can receive sunlight due to the lack of heat exchange with the outside world, such as convection.

b Refers to the effect of a corresponding increase in surface air temperature due to the lack of convection and other heat exchange between greenhouse gases such as carbon dioxide and the outside world.

c Refers to the effect of increasing the amount of carbon dioxide that can affect the surface air temperature in a confined space receiving sunlight, resulting in a corresponding increase in the surface air temperature.

d Refers to the thermal insulation effect of the main greenhouse gases in the atmosphere in a given confined space by reducing the dissipation of surface heat into space.

2 According to the original text, one of the most serious effects of global warming is ( ).

a Reduced or even dried up rivers and the destruction of drinking water sources have led to the expansion of deserts and epidemics of disease in many areas.

b Severe winter storms will become commonplace, and some areas will be too dry to grow a wide range of crops.

c Millions of people have been forced to leave their homes as a result of erosion of coastlines, inundation of coasts and destruction of agricultural production.

d Frequent typhoons have caused heavy precipitation in a short period of time, flooding, inundation of cities, landslides and disruption of transportation.

3 One of the following interpretations of the phrase "global warming is a catastrophe caused by human activities" is incorrect ( ).

a The countries of the world have been slow to take decisive and necessary measures to change the energy mix and to vigorously plant trees, resulting in a growing greenhouse effect in the atmosphere.

b As a result of the massive extraction and burning of coal, oil and natural gas fossil fuels since 1850, the amount of greenhouse gases in the atmosphere has increased significantly.

c As a result of unrestrained human destruction, vast tracts of forests and grasslands on Earth have disappeared dramatically, and deserts have further expanded, resulting in rising surface temperatures.

d Forest fires and grassland degradation caused by lightning strikes and insect infestations have led to a decrease in the amount of vegetation that can absorb carbon dioxide, and there is nothing humans can do about it.

4 Based on the information provided in the original text, one of the following inferences is incorrect ( ).

a Africa is the region most affected by global warming, and it will benefit the most if humanity can prevent the greenhouse effect from intensifying at its roots.

b Once humans are able to control the amount of carbon dioxide in the atmosphere, the greenhouse effect will be prevented at the root.

should be intensified, then skiing will be able to continue in Europe, and typhoons will be far away from Japan.

c In order to avoid increasing the amount of carbon dioxide in the atmosphere, some scientists have advocated replacing fossil fuels with nuclear fuels, which shows that the use of nuclear fuels does not produce carbon dioxide.

d If the concentration of carbon dioxide in the atmosphere continues to decrease, global temperatures are likely to continue to fall, and humanity may face another challenge of global cooling.

Hello, the greenhouse effect is a common environmental problem faced by human beings, which is mainly due to the increase in atmospheric temperature, which causes the melting of polar glaciers and the rise of sea level, reducing the land area and reducing the land environment for human survival and production. Second, the increase in atmospheric temperature will destroy the biological chain of the biosphere, causing organisms to not adapt to the changed ecological environment, or lose their original living home, and thus disappear from the earth. These are the harms of the greenhouse effect to human beings and cause common concern to mankind.

Thank you.

Some time ago, the Proceedings of the National Academy of Sciences of the United States published a study: due to the intensification of the global warming effect, the temperature around the world will reach an unprecedented high. According to the report, according to the current trend of global temperature increase, by 2070, one-third of the total population on the planet will need to live in extreme heat weather.

For the past 6,000 years, scientists have counted that the average person on Earth has lived below 20 degrees Celsius. Then, driven by the greenhouse effect, the average temperature of the earth continues to rise. In another 50 years or so, the average living temperature will rise by about one degree Celsius.

By 2070, the Earth's per capita living temperature will reach around 29 degrees Celsius. That is, if the rate of population growth is not taken into account, more than 3.5 billion citizens on the planet will live in extremely hot weather.

Compared with the intensification of the greenhouse effect, countries around the world pay more attention to national development and production. The world's main energy sources** come from underground oil and coal mines. When we burn diesel and other energy**, we produce large amounts of carbon dioxide, which exacerbates the greenhouse effect.

Therefore, when there is no new breakthrough in the way human beings obtain energy, the world's development and environmental protection will always be on opposite sides. No country in the world is willing to give up the opportunity for its own development for the sake of the earth's environmental protection. And the reason why our country is working so hard to build is because if the earth really comes to the day when it has to limit emissions, powerful countries will always have more say than small countries.

The effects of the greenhouse effect on us Although there is no obvious phenomenon other than hotter temperatures, for nature, there are changes that are visible to the naked eye. The Maldives is a well-known tourist island nation, and the number of people who have visited it in the past is normal. However, some scientists have warned that due to the increase in the greenhouse effect, more and more glaciers on the earth have begun to melt, causing the global sea level to rise.

In a hundred years' time, there is a good chance that the Maldives will be submerged. Since the news spread, more and more people have been visiting the Maldives. The Maldives is just one example, and other similar island nations besides the Maldives are at risk of the same.

There is another country that is not an island but faces the same danger, and that is Venice, known as the "City of Water". As early as 2019, Venice had already suffered a dangerous situation. In November, Venice was hit by a flood that flooded a large number of residential buildings.

Although this is just a flood, many people are beginning to worry about their future. The crisis in Venice and the Maldives is not yet in sight, and Kivalina, a coastal area in Alaska, is gradually being swallowed by the sea. It will only take 5 years for the town to cease to exist.

For us, the greenhouse effect does cause an increase in the temperature around us, especially in the summer. It will also exacerbate the melting of glaciers at the Antarctic and Arctic poles. The consequences are severe.

The increasing greenhouse effect will lead to the melting of glaciers, and then the rising sea level, which may inundate some countries and lands, and have a great impact on people's lives.

With the intensification of the greenhouse effect, the global temperature rises, the melting rate of glaciers in the North and South Poles accelerates, and the land area gradually increases, although it is conducive to the opening of the Arctic shipping lanes, but it is not good for the natural environment, and some animals will also be on the verge of extinction, such as polar bears, arctic foxes and in the Arctic. Some of the animals live.
