Project opening report and personal summary on the generation and influence of greenhouse effect

The topic opening report and personal summary of the generation and influence of greenhouse effect have been hard for such a period of time, and finally it is time for a bumper harvest. Looking back on these days, we studied this topic together and encountered many difficulties. Those pictures are still clear in front of us. I remember that we established many topics at that time, and we had a heated discussion at that time. Although the difficulty of this topic is not particularly high, we still encountered many difficulties when we went to investigate, such as poor cooperation among team members and time planning. But in the end, with our efforts, we overcame them one by one. As we all know, China is one of the most polluted countries in the world. Many people in China know that China is seriously polluted, but they don't know how to start from themselves and continue to do things that will destroy the environment. Obviously, it is not in line with the growing prosperity. China's economy and politics are becoming more and more prosperous. As citizens of China, we should start from ourselves, care for the earth, care for our neighbors, pay attention to world climate issues, and actively participate in energy conservation and emission reduction. We should contribute to the environmental protection in China. It may be a little easy to say this, but when we did this survey, we learned about the current situation of the world climate and the harm caused by the greenhouse effect from various channels, which was deeply touched. Although it is not yet possible to completely eliminate the greenhouse effect, we can do what we can then. Paying attention to greenhouse effect and climate change means paying attention to our future. If all people can practice, our future will be full of sunshine.

There is only one earth for more than 500 years, and the ecological environment must be maintained by every citizen. Now, the surrounding environment is changing. Flowers and plants wither, and animals are facing various environmental crises. Environmental degradation is man-made, and it takes someone to tie the bell to solve the problem. We must work together to protect the earth.

Through this research study, I have a better understanding of the harm of greenhouse effect. Fossil energy is widely used in industry and emits a lot of carbon dioxide. Because humans cut down forests indiscriminately, there are not enough trees to absorb all the carbon dioxide, and the temperature is gradually rising. Strive to protect our beautiful home.

Through this in-depth investigation and study, I have a further understanding of the global greenhouse effect. Now, the global environment is deteriorating every day. We shouldn't wait until later to solve it. We should take effective measures to protect our planet as soon as possible. To protect the earth and the environment we live in, we can start with the little things around us. Let our earth be more beautiful tomorrow.

After this in-depth investigation and study, I deeply realize that the speed of environmental deterioration is much faster than I thought. The earth is our only home, on which we have lived for generations. Therefore, we should cherish our homeland and protect our earth, and our life will be better.

Through this research study, every team member is very United and harmonious, which enables us to successfully complete this activity and increase our friendship. And let me understand the greenhouse effect more deeply, and also deeply understand the disaster that the global greenhouse effect brings to human beings and nature. In order to reduce the excessive carbon dioxide in the atmosphere, on the one hand, people need to save electricity and drive less cars; On the other hand, it is necessary to protect forests and oceans and not to cut down trees indiscriminately. We can also protect green plants by planting trees, reducing the use of disposable wooden chopsticks, saving paper and not trampling on the lawn, so that they can absorb more carbon dioxide to help slow down the greenhouse effect. Friends, let's try to slow down the greenhouse effect and make our home better tomorrow.

All right, that's all. Organize your own language, only talk about your own gains, and Bian Xiaolong contributes.

Generation and influence of greenhouse effect. Production:

The greenhouse effect is mainly caused by the excessive burning of coal, oil and natural gas in modern industrial society, which releases a lot of carbon dioxide gas into the atmosphere after burning. Carbon dioxide gas has the functions of heat absorption and heat insulation. The result of its increase in the atmosphere is the formation of an invisible glass cover, which prevents the heat radiated by the sun to the earth from spreading to outer space, and as a result, the surface of the earth becomes hot. Therefore, carbon dioxide is also called greenhouse gas.

2。 Impact:

Environmental effect

Climate Change: "Global Warming"

The increase of greenhouse gas concentration will reduce infrared radiation to outer space, so the earth's climate needs to be changed to achieve a new balance between absorbing and releasing radiation. This transformation may include "global" warming of the earth's surface and lower atmosphere, because it will release excessive radiation. However, a slight increase in the earth's surface temperature may trigger other changes, such as changes in atmospheric cloud cover and circulation. Some of these changes will aggravate the ground warming (positive feedback), while others will slow down the warming process (negative feedback).

In its third assessment report, the Intergovernmental Panel on Climate Change used a complex climate model to estimate that by 265,438+000, the global average surface temperature will rise by 65,438+0.4 to 5.8℃. This is expected to take into account the role of suspended particles in the atmosphere in the cooling of the earth's climate and the role of the ocean in absorbing heat energy (the ocean has a large heat capacity). However, there are still many uncertain factors that will affect this calculation result, such as the prediction of future greenhouse gas emissions, various feedback processes to climate change and the degree of ocean heat absorption.

2) The increase of pests and diseases on the earth.

The greenhouse effect will make prehistoric deadly viruses threaten human beings.

American scientists have recently warned that due to the melting of Arctic ice due to global temperature rise, prehistoric deadly viruses frozen for more than100000 years may reappear, leading to global epidemic panic and seriously threatening human life.

Scientists at Syracuse University in New York pointed out in the latest issue of Scientist magazine that they had discovered a plant virus TOMV earlier. Because it is widely spread in the atmosphere, it is inferred that this virus has also been found in the Arctic ice sheet. So the researchers extracted four pieces of ice from Greenland, ranging in age from 5 million years to 6.5438+0.4 million years, and found the TOMV virus in the ice. Researchers say that the surface of the virus is surrounded by a solid protein, so it can survive in adversity.

This new discovery makes researchers believe that a series of epidemic viruses such as influenza, polio and smallpox may be hidden deep in the ice. At present, human beings have no resistance to these primitive viruses. When the global temperature rises and the ice melts, these viruses buried in the ice for thousands of years or more may resurface and form an epidemic. Scientists say that although they don't know the survival hope of these viruses or the chance to adapt to the ground environment again, they certainly can't rule out the possibility of the virus coming back.

3) sea level rise

If "global warming" is happening, there are two processes that will lead to sea level rise. First of all, the seawater is heated and expanded, which makes the water level rise. The second is that the melting of glaciers and ice in Greenland and Antarctic continent has increased the water content of the ocean. It is predicted that from 1900 to 2 100, the average sea level of the earth will rise by 0.09-0.88m..

Global warming is about to reach its peak in the South Pacific islands.

Global warming leads to the rapid melting of the ice sheets in the North and South Poles and the rising sea level. According to a report of the World Bank, even a slight sea level rise of 1 m is enough to cause 56 million people in developing countries to become refugees. The world's first inhabited island submerged by seawater is about to be born-Katri Island, located in Papua New Guinea, a South Pacific country. Now the main roads on the island are waist-deep, and all agricultural land has turned into mud.

4) The climate is abnormal, and ocean storms are increasing.

5) The land is dry and the desertification area increases.

Potential impact on human life

1) Economic impact

More than half of the world's population lives in the coastal area of 100 km, and most of them live in urban areas near seaports. Therefore, the significant rise of sea level will cause serious economic damage to coastal low-lying areas and islands, such as accelerating the erosion of coastal beaches by seawater and pushing underground fresh water farther inland through rising seawater.

2) The impact of agriculture

Experiments show that plants will grow faster and taller in the environment with high concentration of CO2. However, the result of "global warming" may affect the atmospheric circulation, and then change the global rainfall distribution and the water content of the surface soil on all continents. Due to the failure to clearly understand the impact of "global warming" on regional climate, the transformation of plant ecology has not yet been determined.

III) Impact of marine ecology

The disappearance of coastal marshes will definitely reduce the number of fish, especially shellfish. The salinity of estuary water quality may reduce the species of freshwater fish, on the contrary, the species of marine fish in this area may also increase relatively. As for the impact on the overall marine ecology, it is still unclear.

Iv) Impact of water recycling

Global rainfall may increase. However, the change of regional rainfall is still unknown. Some areas may have more rainfall, but some areas may have less rainfall. In addition, the increase of temperature will increase the evaporation of water and put pressure on the use of surface water sources.

Scientists predict that if the earth's surface temperature continues to rise at the current rate, by 2050, the global temperature will rise by 2-4℃, polar icebergs will melt greatly, resulting in a sharp rise in sea level, and some island countries and coastal cities will be submerged, including several famous international cities: new york, Shanghai, Tokyo and Sydney.

However, the greenhouse effect is not all bad. Because the coldest high latitudes have the greatest warming, agricultural areas will be greatly promoted to the polar regions. The increase of CO2 is also beneficial to the photosynthesis of plants and directly increases the yield of organic matter.

The production and influence of greenhouse effect

(English: greenhouse effect), also known as "greenhouse effect", is a common name for atmospheric heat preservation effect. The atmosphere can make the short-wave radiation of the sun reach the ground, but the long-wave radiation emitted by the ground is absorbed by the atmosphere, which raises the temperature of the ground and the lower atmosphere. Because its function is similar to the greenhouse for cultivating crops, it is named the greenhouse effect. Since the industrial revolution, carbon dioxide and other heat-absorbing greenhouse gases emitted into the atmosphere by human beings have increased year by year, and the greenhouse effect of the atmosphere has also been enhanced, which has caused a series of serious problems such as global warming and attracted the attention of all countries in the world.

Brief introduction of greenhouse effect

Name: greenhouse effect (taken from the Chinese version of the definition of greenhouse effect in IPCC glossary). )

The greenhouse effect caused by environmental pollution refers to the phenomenon that the earth's surface becomes hot.

The greenhouse effect is mainly caused by excessive burning of coal, oil and natural gas in modern industrial society, which releases a lot of carbon dioxide gas into the atmosphere after burning. Carbon dioxide gas has the functions of heat absorption and heat insulation. The result of its increase in the atmosphere is the formation of an invisible glass cover, which prevents the heat radiated by the sun to the earth from spreading to outer space, and as a result, the surface of the earth becomes hot. Therefore, carbon dioxide is also called greenhouse gas.

Greenhouse gases effectively absorb infrared radiation emitted by the same gases and clouds on the earth's surface and the atmosphere itself. Atmospheric radiation is emitted in all directions, including to the surface of the earth below. Greenhouse gases absorb heat in the ground-troposphere system. This is called "natural greenhouse effect". Atmospheric radiation is closely related to the temperature level of its gas emission. In the troposphere, the temperature generally decreases with the increase of altitude. Infrared radiation emitted into space from a certain height is generally generated at a height with an average temperature of-19℃, and the temperature of the earth's surface can be kept at an average temperature of 1 4℃ due to the income balance of solar radiation. The increase of greenhouse gas concentration leads to the enhancement of atmospheric opacity to infrared radiation, which leads to the emission of effective radiation into space from lower temperature and higher altitude. This creates radiation forcing, and this imbalance can only be compensated by the temperature rise of the ground troposphere system. This is the "enhanced greenhouse effect". If this effect does not exist in the atmosphere, the surface temperature will drop by about 3 degrees or more. On the other hand, if the greenhouse effect continues to strengthen, the global temperature will continue to rise year by year.

origin

The greenhouse effect is mainly caused by the excessive burning of coal, oil and natural gas in modern industrial society, which releases a lot of carbon dioxide gas into the atmosphere after burning.

Carbon dioxide gas has the functions of heat absorption and heat insulation. Because of its increase in the atmosphere, an invisible glass cover is formed, which prevents the heat radiated by the sun to the earth from spreading to outer space and reflects infrared rays, and as a result, the surface of the earth becomes hot. Therefore, carbon dioxide is also called greenhouse gas.

Human activities and nature also emit other greenhouse gases, such as chlorofluorocarbons (CFCs), methane, low-level ozone and nitrogen oxides. On earth, plankton in the ocean and forests on land, especially tropical rainforests, can absorb a lot of carbon dioxide.

In order to reduce the excessive carbon dioxide in the atmosphere, on the one hand, people need to save electricity as much as possible (because power generation needs to burn coal) and drive less cars. On the other hand, protect forests and oceans, for example, don't cut down forests and prevent the oceans from being polluted, so as to protect the survival of plankton. We can also protect green plants by planting trees, reducing the use of disposable wooden chopsticks, saving paper (paper wood) and not trampling on the lawn, so that they can absorb more carbon dioxide to help slow down the greenhouse effect.

The research report on the generation and influence of greenhouse effect is about 3000 words. Greenhouse effect is a concept put forward by environmentalists, which calls for emission reduction on the grounds that carbon dioxide absorbs infrared rays and the temperature will rise.

The starting point is good.

However, carbon dioxide absorbs only a very narrow band in the infrared spectrum, and its content has increased by one tenth of a million (200PPM to 300PPM) in the past 30 years. The data vary greatly from place to place. The content of water vapor in the air is much higher than that of carbon dioxide (percentage), and it also absorbs infrared rays, resulting in a "greenhouse effect" far higher than that of carbon dioxide. (You can check the relevant reports of Chinese Academy of Sciences online)

To really find out the reasons for the deterioration of the earth's climate, we should find out the reasons from many aspects, such as the Antarctic ice sheet and Himalayan ice sheet drilled by a research institute, and confirm that the temperature at the bottom of the ice sheet has not changed. This is part of the exercise. Many are still being explored.

The purpose of studying the generation and influence of greenhouse effect will bring the following serious consequences:

1) the increase of pests and diseases on the earth;

2) sea level rise;

3) Abnormal climate, increasing ocean storms;

4) The land is dry and the desertification area increases.

The generation and influence of greenhouse effect and land desertification: The aggravation of greenhouse effect is mainly caused by excessive burning of coal, oil and natural gas in modern industrial society, which releases a lot of carbon dioxide gas into the atmosphere after burning. Carbon dioxide gas has the functions of heat absorption and heat insulation. The result of its increase in the atmosphere is the formation of an invisible glass cover, which prevents the heat radiated by the sun to the earth from spreading to outer space, and as a result, the surface of the earth becomes hot.

Are you interested in important desertification? Environmental impact: The greenhouse effect is a phenomenon that the excessive emission of greenhouse gases such as carbon dioxide enhances the thermal insulation function of the atmosphere, warms the world, raises the temperature and evaporates vigorously. Deserts are generally distributed near the Tropic of Cancer or inland. The reason is that there is little precipitation, which leads to plants unable to grow and land desertification. Now the water vapor in the air can't condense, and there is less precipitation. Semi-arid areas gradually become arid areas, and the desert area naturally expands.

Climate Change: "Global Warming"

The increase of greenhouse gas concentration will reduce infrared radiation to outer space, so the earth's climate needs to be changed to achieve a new balance between absorbing and releasing radiation. This transformation may include "global" warming of the earth's surface and lower atmosphere, because it will release excessive radiation. However, a slight increase in the earth's surface temperature may trigger other changes, such as changes in atmospheric cloud cover and circulation. Some of these changes will aggravate the ground warming (positive feedback), while others will slow down the warming process (negative feedback). In its third assessment report, the Intergovernmental Panel on Climate Change used a complex climate model to estimate that by 265,438+000, the global average surface temperature will rise by 65,438+0.4 to 5.8℃.

The greenhouse effect can make prehistoric deadly viruses threaten human beings. American scientists have recently warned that the prehistoric deadly virus that has been frozen for more than100000 years may reappear, causing global epidemic panic and seriously threatening human life. Harm of greenhouse effect to human beings

It is predicted that from 1900 to 2 100, the average sea level of the earth will rise by 0.09-0.88m.. Global warming, the South Pacific island will soon have no roof. Global warming leads to the rapid melting of the ice sheets in the North and South Poles and the rising sea level. According to a report of the World Bank, even a slight sea level rise of 1 m is enough to cause 56 million people in developing countries to become refugees.

Therefore, the significant rise of sea level will cause serious economic damage to coastal low-lying areas and islands, such as accelerating the erosion of coastal beaches by seawater and pushing underground fresh water farther inland through rising seawater.

2) The impact of agriculture

Experiments show that plants will grow faster and taller in the environment with high concentration of CO2. However, the result of "global warming" may affect the atmospheric circulation, and then change the global rainfall distribution and the water content of the surface soil on all continents. Due to the failure to clearly understand the impact of "global warming" on regional climate, the transformation of plant ecology has not yet been determined. 20 1 1 In May, Stanford University published a study on global warming sponsored by the RockefellerFoundation, pointing out that agricultural products in the United States, Canada and Mexico have hardly been affected by global temperature rise in the last 30 years. This is the first time that the United States has published a research report on the relationship between atmospheric temperature and crop yield. The report was published in the latest Science Express magazine. David Lobell, an assistant professor of the Earth Environment System at Stanford University, said that the research started at 1980 to monitor the relationship between greenhouse effect and crop yield. It is pointed out that since 1980, the global wheat yield has decreased by 5.5% and the global corn yield has decreased by 4%, and the global rice and soybean have not been greatly affected. Robert pointed out that the United States is the world's largest producer of corn and soybeans, accounting for about 40% of the global output, and has not been greatly affected by the greenhouse effect in the past 30 years. Robert stressed that "it has not been affected so far, and it is hard to say in the next decade. Robert said that wheat outside the United States such as Russia, France, India and other countries; Corn production in China and Brazil has declined in the past 30 years. The corn and soybean producing areas in the United States have not been affected by the greenhouse effect, which has aroused great interest from climatologists. Why have they not been affected? " Scientists re-examine the impact of the greenhouse effect in different parts of the world and explore whether there are other reasons for the greenhouse effect. Robert pointed out that according to the research of Global Interconnected Climate Research (IPCC) since 1950, the earth's temperature has risen by 0. 13 degrees Celsius every ten years on average. IPCC predicts that the temperature will rise even faster in the next 20 to 30 years. "If this prediction is true, crop yields in the United States and Canada will also be affected. At the same time, the report pointed out that the global crop price has increased by 20% from 1980 due to the impact of greenhouse effect.

III) Impact of marine ecology

The disappearance of coastal marshes will definitely reduce the number of fish, especially shellfish. The salinity of estuary water quality may reduce the species of freshwater fish, on the contrary, the species of marine fish in this area may also increase relatively. As for the impact on the overall marine ecology, it is still unclear.

Iv) Impact of water recycling

Global rainfall may increase. However, the change of regional rainfall is still unknown. Some areas may have more rainfall, but some areas may have less rainfall. In addition, the increase of temperature will increase the evaporation of water and put pressure on the use of surface water sources. Scientists predict that if the earth's surface temperature continues to rise at the current rate, by 2050, the global temperature will rise by 2-4℃, polar icebergs will melt greatly, resulting in a sharp rise in sea level, and some island countries and coastal cities will be submerged, including several famous international cities: new york, Shanghai, Tokyo and Sydney.

6) Impact on gender balance

High temperature environment is easy to bring up boys and babies, and low temperature environment is easy to bring up girls and babies. Researchers are even more worried that under the greenhouse effect of rising global temperatures, the probability of a baby boy being born will be higher and higher, which may lead to an imbalance between men and women. Previous studies have long found that the sex, birth time and environmental temperature of rats and bats are closely related. In order to find out the relationship between the sex of human babies and the ambient temperature, German researchers tracked the birth records between 1946- 1995 and compared the local temperature changes. The results show that April to June is the month with the most boys born, and 10 is the month with the least boys born. Further analysis shows that the environmental temperature one month before fertilized eggs are combined, that is, the environmental temperature of boys and girls one month before sexual intercourse, is an important factor affecting the sex of babies. High temperature environment is easy to bring up boys and babies, and low temperature environment is easy to bring up girls and babies. The reason why temperature affects the sex of the baby is that the researchers assume that high temperature will affect the X chromosome of * * *, making it difficult for the baby girl to be born; Low temperature will affect the Y chromosome of * * *, making it difficult for a baby boy to be born. Another hypothesis is that the higher the temperature, the stronger the desire for * * * *. High temperature environment will increase the frequency of sex between men and women, and also make women more likely to get pregnant. Another study believes that * * * with Y chromosome swims faster; But * * * with X chromosome is stronger. Therefore, in the case of frequent sexual behavior, * * with Y chromosome is more likely to combine with eggs and give birth to a baby boy. In the case of decreased sexual behavior, * * * with X chromosome is more likely to wait for the opportunity to combine with eggs, and it is easier to give birth to female babies. Researchers are even more worried that under the greenhouse effect of rising global temperatures, the probability of a baby boy being born will be higher and higher, which may lead to an imbalance between men and women.

People in Catalina Island, dressed in traditional costumes, have always been happy in their life of knowing and doing, have been independent for hundreds of years, and have always maintained a traditional lifestyle. However, due to global warming caused by human destruction of the environment, they are facing the fate of being submerged by seawater. Paul Tabashi, an environmentalist on Katrina Island, said: "They were attacked by ocean forces and flooded constantly. The original area has been changed and destroyed, and almost all places have been submerged by seawater. It is unbearable that mosquitoes and flies are swarming and malaria is rampant.

The Amazon rainforest is disappearing.

The Amazon rainforest, the largest tropical rain forest in South America, is gradually disappearing, which aggravates the global warming crisis. The Amazon rainforest, known as the lung of the earth, covers 5% of the earth's surface and produces 20% of oxygen and 30% of biological species in the world. Due to illegal logging and reclamation, the Amazon rainforest is disappearing at an area of 7,700 square miles per year, equivalent to the area of New Jersey. The disappearance of the rainforest will not only aggravate global warming, but also make many creatures that can only live in the rainforest face the crisis of extinction. In the past 40 years,

A new ice age is coming.

Another very serious consequence of global warming is the arrival of the ice age. The melting of the Antarctic ice sheet has caused a large amount of fresh water to be injected into the ocean, and the concentration of seawater has decreased. As a result, the "ocean conveyor belt" gradually stopped: the warm current could not reach the cold sea; The cold current can't reach the warm sea. As the global temperature drops, another ice age is coming. Most parts of the northern hemisphere are frozen, and successive snowstorms and tornadoes will sweep across the mainland. The ultimate harm: it may lead to the dinosaur era coming again!

The greenhouse effect has only one impact on the earth, and the ecological environment must be maintained by every citizen. Now, the surrounding environment is changing. Flowers and plants wither, and animals are facing various environmental crises. Environmental degradation is man-made, and it takes someone to tie the bell to solve the problem. We must work together to protect the earth.

Through this research study, I have a better understanding of the harm of greenhouse effect. Fossil energy is widely used in industry and emits a lot of carbon dioxide. Because humans cut down forests indiscriminately, there are not enough trees to absorb all the carbon dioxide, and the temperature is gradually rising. Strive to protect our beautiful home.

Through this in-depth investigation and study, I have a further understanding of the global greenhouse effect. Now, the global environment is deteriorating every day. We shouldn't wait until later to solve it. We should take effective measures to protect our planet as soon as possible. To protect the earth and the environment we live in, we can start with the little things around us. Let our earth be more beautiful tomorrow.

After this in-depth investigation and study, I deeply realize that the speed of environmental deterioration is much faster than I thought. The earth is our only home, on which we have lived for generations. Therefore, we should cherish our homeland and protect our earth, and our life will be better.

Through this research study, every team member is very United and harmonious, which enables us to successfully complete this activity and increase our friendship. And let me understand the greenhouse effect more deeply, and also deeply understand the disaster that the global greenhouse effect brings to human beings and nature. In order to reduce the excessive carbon dioxide in the atmosphere, on the one hand, people need to save electricity and drive less cars; On the other hand, it is necessary to protect forests and oceans and not to cut down trees indiscriminately. We can also protect green plants by planting trees, reducing the use of disposable wooden chopsticks, saving paper and not trampling on the lawn, so that they can absorb more carbon dioxide to help slow down the greenhouse effect. Friends, let's try to slow down the greenhouse effect and make our home better tomorrow.
