The background of global warming
Global warming refers to global warming. Nearly 100 years, global average temperature through the cold - warm - cold - warm twice fluctuations, the overall look for the upward trend. Into the eighties, the global temperature increased significantly. 1981 to 1990 the average global temperature increase of more than 100 years ago, 0.48 ℃. The main cause of global warming is nearly a century of human heavy use of fossil fuels (such as coal, oil, etc.), large amounts of co2 emissions and other greenhouse gases. Because of these greenhouse gases on the radiation from the sun through the highly visible, while on the long-wave radiation reflected from the earth is highly absorbent, it is often said that the "greenhouse effect", leading to global warming. Consequences of global warming will lead to a global redistribution of precipitation, melting glaciers and permafrost, rising sea levels, not only endanger the natural balance of the ecosystem, but also threaten human food supply and living environment. There specific reasons for the global warming trend is that people burned to generate energy or fossil deforestation and the burning of the carbon dioxide generated when entering the Earth's atmosphere. Intergovernmental Panel on Climate Change, according to climate model predictions, 2100 date, estimated that global temperatures will rise by about 1.4-5.8 degrees Celsius (2.5-10.4 degrees Fahrenheit). According to this forecast, global temperature will occur over the past 10,000 years, there has never been a huge change, and thus the global environment and potentially significant impact.

History and Forecast of Global Warming
Global warming is real and underway! Mainstream scientific consensus on global warming is becoming clearer every day in our climate change are real, they are underway. Since the beginning of the 20th century, Earth's average surface temperature increased by about 1.1f (0.6 degrees C). In the past 40 years, temperature increased by about 0.5f (0.2-0.3 degrees Celsius). In the past 400-600 years, global warming, in the 20th century is more than at any one time, 10 / 7 for years, in the 20th century occurred in the 20th century, 90's, one of the most powerful since 1998, the afternoon was the hottest year since reliable temperature measurements began. In addition, changes in the natural environment to support the fact that the earth is warming; mountain giaciers are waning; in the past four decades, the Arctic ice thickness has declined by about 40%; global sea level rise of about three times faster Over the past 100 years than in the previous 3,000 years An increasing number of studies have shown that plants and animals change their range and behavior response to climate. According to the instrumental record, compared to 1860-1900, global land and ocean temperatures increased by 0.75 degrees Celsius. Since 1979, land temperatures rise faster than twice as fast as ocean temperatures (land temperatures rose by 0.25 degrees Celsius, while the ocean temperature rose by 0.13 degrees Celsius). According to satellite temperature probe, temperature of the troposphere to 0.12 degrees Celsius per decade increase of 0.22 degrees. In 1850 a couple of thousand years ago, although there was the Medieval Warm Period and Little Ice Age, but the public believe that global temperatures are relatively stable. According to the National Aeronautics and Space Administration's Goddard Institute for Space Studies of the study estimated that, since the 1800s are widely used measuring instruments began in 2005 was the warmest year, more than the record high in 1998 by several degrees Celsius. World Meteorological Organization and the UK Climatic Research Unit has a similar estimate was expected in 2005 is second only to the second warmest year in 1998. In the modern history of mankind have a number of temperature records. These records are from different places, accuracy and reliability are not the same. In 1860, global temperatures have similar equipment to record, I believe that very few records of the year by the urban heat island effect. From recent multi-year records of the millennium show long-term vision, in the temperature record over the past 1,000 years can be seen in the discussion of the differences. Last 50 years, the process of climate change is very clear, detailed temperature records entirely. By 1979, humans have started to use satellites to measure the temperature measurement the temperature of the troposphere. AP U.S. scientists found that the ancient agricultural activities has made the world to avoid entering a new ice age. This shows that human-induced global warming may continue for thousands of years. The researchers said, cut down the tree and the first piece of reclaimed land of prehistoric farmers in the atmosphere of methane and co 2 and other greenhouse gases changed a lot, so the gradual rise in global temperatures. University of Virginia Professor Ruddiman said: "If it was brought to agriculture in the early greenhouse gas, the current global temperature is probably still the glacial period the temperature." Ruddiman recognized, the results are very likely to cause controversy. National Center for Atmospheric Research, 17, said scientists predicted by two recent studies, even now the world's greenhouse gas emissions stabilized at 2000 levels, global warming and sea level this century, the rising trend has become irreversible. National Center for Atmospheric Research scientist, published in the 18 "Science" magazine published two consecutive papers, from different angles predict the trend of global climate change. Their results will be under the United Nations Intergovernmental Panel on Climate Change assessment, included in the next published in 2007, reports of global climate change. In the first paper, the National Center for Atmospheric Research Weige Lei proposed a relatively simple mathematical models to understand global climate change. He considered that as an ocean, "thermal inertia" of greenhouse gases outside the response has been lagging behind the trend of global warming this century is only the consequences of past emissions of greenhouse gases. According to Wei Gelei predicted that 2400 has been present in the composition of greenhouse gases in the atmosphere, average global temperatures will rise at least 1 degree Celsius; constantly new emissions of greenhouse gases, in turn lead to additional increases in global average temperatures 2 to 6 degrees Celsius . These two factors will cause sea levels were rising 10 cm per century and 25 cm. In the paper he said that to curb global warming trend, and now global greenhouse gas emissions must be controlled in an extremely low level, even then I am afraid the trend of sea level rise is difficult to avoid, 10 cm per century increase in speed may be the most optimistic forecasts. Gerald Meyer, who by the second paper published in the forecast, due to "thermal inertia" exists, even in this century, human beings do not emit any greenhouse gases to the atmosphere, average global temperature by 2100 will rise at least 0.5 degrees Celsius above the sea level will rise by 11 cm, of which the rate of sea level rise earlier than scientists predicted higher more than doubled. Meyer explained that the forecast is not considered because the previous melting of the glaciers. Meyer's team used two mathematical models, using supercomputer simulations of the global greenhouse gas emissions are low, medium and high climate and sea level changes.

Conditions of global warming
A large number of global warming and human greenhouse related emissions of greenhouse gases. However, researchers in Japan and Denmark, has recently pointed out that the increase of greenhouse gases contributing to climate warming is not the only reason for changes in solar activity, which also played a role. According to "Japanese Economic News" reported that the Yokohama National University, Institute of environmental information of public record, Professor Ito has produced a chart. From the figure, over the past 200 years the Earth average temperature and the curve of the solar magnetic field strength consistent. Ito public record deduced that solar activity has an impact on global warming, just global warming greenhouse gases may not be fully explained. Solar activity affect Earth's temperature by experts concerned about a long time. In general, the sunspot number, when violent solar activity. Such as the historical data was documented during the 17th century very few sunspots appeared, when the Earth's climate is relatively cold. However, detection of ground access to information also shows that changes in solar intensity caused by changes in solar radiation energy by only 0.1%, so small changes appear insufficient to cause much impact on the climate. Recently, however, the international space science community there is a hypothesis that solar activity may change the amount of cloud over the earth, "enlarge" the impact of the Sun on the Earth, which is about climate change. Danish scientists put forward the hypothesis speculated that cosmic rays can be fired at the Earth a more stable manner so that part of the atmosphere ionized so easy to generate clouds, which absorb the sun's a lot of radiation and reduce the Earth's temperature. However, the peak of solar activity, the release of high-speed stream of charged particles, cosmic rays fired at the Earth can interfere, so that the cloud is not easy to form, leading to warming the planet. Currently, the Danish researchers are studying cloud formation and a variety of factors, to demonstrate the above hypothesis. Japanese experts also raised, although the magnitude of changes in solar radiation energy is only 0.1%, but they found that the energy of the Earth's atmosphere can absorb the sun's ultraviolet range of the amount of change in a few percent, which would increase the amount of atmospheric absorption the ozone layer temperature. Japan Meteorological Research Institute, head of the second Kunihiko Kodera, said changes in temperature will affect the ozone layer troposphere, and thus the impact of cold weather and monsoons, but it is not clear that these mechanisms can have much impact on global warming. In order to continue to study this issue and others Kunihiko Kodera, an international research team began work last year.

Causes of global warming
Many reasons for global warming, after the following general points: 1. Population growth factor The dramatic increase in population in recent years led to one of the main factors of global warming. Same time, it was a serious danger rib balance between the natural ecological environment. So much of the population, their emissions of carbon dioxide each year as it will be a staggering figure, and the results will lead directly to the system of carbon dioxide in the atmosphere continue to increase, creating a carbon dioxide "greenhouse effect" will directly affect the Earth's surface climate change. 2. Air pollution factors Currently, the increasingly serious environmental pollution has posed a major global problem, but also led to one of the main factors of global warming. Now, on global climate change research has clearly pointed out that since the last century from the Earth's surface temperature has already begun to rise. 3. Aggravating factor in the marine environment Currently, sea level changes are continuously rising trend was, according to the experts predicted that the next century, sea levels could rise 50cm. If not taken and the measures will lead directly to the destruction and pollution of freshwater resources, and other adverse consequences. In addition, a large number of land-based places of toxic chemical waste generated and solid waste continuously into the sea; place in the great sea vent (leak) oil, and events caused by human activities, environmental degradation in coastal areas and so lead to the destruction of marine ecological environment a major factor. 4. Land erosion, desertification and other destructive elements 5. Dropped factors of forest resources In the world, due to natural or man-made factors caused a significant forest area is drastically reduced. 6. Acid rain hazards Acid rain to the ecological impact of the environment has become increasingly attracted worldwide attention. Acid rain can damage forests, acidification of lakes, endangering the biological. Currently, the world's acid rain and more concentrated in Europe and North America, acid rain occurred in most developed countries, some developing countries, acid rain is also rapidly develop. 7. Species extinction factor in accelerating On Earth is a precious human resources, and the diversity of human survival and development. However, the biological species on Earth is disappearing at an unprecedented rate. 8. Water Pollution Factors According to the Global Environment Monitoring System Water Quality Monitoring Project showed that about 10% of the global monitoring of water pollution, this century, human water consumption is increasing rapidly, while water pollution is continuously expanding scale, which formed a fresh water supply and demand of a contradiction. Thus, the treatment of water pollution is very urgent and important. 9. Toxic waste pollution factors Growing toxic chemicals pose to human survival is not only a serious threat, and the ecological environment of the Earth's surface will also be harm.

Temperature prediction of global warming
German researchers said that the future may be much higher than the global temperature had made some scientists predict, if the new computer models on climate change predictions made are correct. According to Reuters, the Intergovernmental Panel on Climate Change (ipcc, by the national meteorological experts, studying global climate trends) had predicted that by the end of the century, with the doubling of carbon dioxide, global temperatures will rise by 1.5 to 4.5 degrees Celsius. But Germany and the United States Institute of 迈因拉特安德 Lieai Yinzimapu Professor of Chemistry and his research team's latest calculation method is that the maximum rate of global warming could reach six degrees Celsius. Professor Andrea said, this new method is to aerosols, greenhouse gases and the effects of reunification with the biosphere, changes in the past predictions on climate change, even if people can tolerate it from the developed to the extent of the risk of a more rapidly changing position. Professor Andrea greenhouse gases is causing global warming, compared to the accelerator, the presence of aerosols can slow down the rise in temperature. Suspended particles are generated in the combustion air, chemicals and soot into small particles. With the new air cleaning conditioning use will reduce the number of suspended particles, which along with its cooling effect will become smaller. Instead, global temperatures but it will rise. Suspended particles in the atmosphere can only stay a week, while greenhouse gases can stay about 50 years time. In other words, the cooling effect of aerosols decrease faster, while reducing greenhouse gas more slowly. Thus, in the long-term competition, greenhouse gases will eventually overcome the suspended particles, followed by hot weather is hot. However, Professor Andrea also admitted that the situation with a high degree of scientific uncertainty, climate change is far beyond the experience and the scope of scientific understanding can be achieved. If his calculations are correct, climate change will be the 21st century, more than the Intergovernmental Panel on Climate Change forecasts.

The consequences of global warming
AP U.S. Worldwatch Institute researchers recently warned that global warming will cause global agricultural production, perhaps in the next century the situation of food shortage occurs. Researchers in the analysis of the United Nations and the United States National Academy of Sciences of the information and world rice market trends obtained in this view. World Observational studies suggest that global warming and the decline in groundwater level will be the global food supply of direct incentives, trends in global rice prices reflect this. Global warming will cause rising sea levels, coastal areas will be flooded, said before Atlantis is so submerged. Statistics released by the U.S. government, even in last year's world grain harvest, wheat and corn prices decline, the rice prices still rose 30% to 260 dollars per ton. U.S. National Academy of Sciences published a study last year showed abnormal temperature rise in rice-growing season will reduce the harvest. In addition, the global decline in groundwater levels in many regions, the exhaustion of wells, will also affect food production.

How to slow global warming
Global warming the Earth has changed in many aspects, some of which change itself also inhibit global warming trend. First, global warming make the earth part of the ice and snow melt, the global increase in the total liquid water. The specific heat of liquid water above the ice, the heat due to the increased greenhouse effect due to increase in the total liquid water on Earth without the water temperature increased significantly, due to the increased greenhouse effect heat though the rock on the planet, land, etc. temperature increased significantly, but because of its occurrence of liquid water on Earth heat exchange, so that the whole earth was no longer significant warming, to some extent off_set_ the greenhouse effect, delaying the melting of snow and ice on Earth. Second, global warming green plants on the planet strong growth, photosynthesis over global warming before its absorbing more carbon dioxide (the main part of the greenhouse gases), fixed part of the greenhouse gases, so that this part will not stop the world from greenhouse gases out on the heat radiation, but also to some extent off_set_ the greenhouse effect. Scientists have proposed a bold idea, to build around the Earth or a spacecraft composed of small particles of artificial space ring, covered the tropical sun, Earth's temperature regulation. However, some opponents argue that this idea will certainly be some side effects, one can effectively scatter the sunlight will make the particles with each of us have become, and the full moon night sky as bright; and budget for this program will be alarmingly high, may reach 6 trillion to 200 trillion U.S. dollars, and even the world's most abundant funds NASA research institutions can not afford, if the scattering particles into the space ship, then, may be less budget, dropped to 500 billion U.S. dollars estimated to be around. Since the birth of earth, air temperature was down several times, solar radiation, the clouds and greenhouse gases and other factors have been or are affecting our climate. If the earth around a particle or a spacecraft on the composition of the "belt", then there will be a shadow over the equator, to deploy these particles, they must use some special control spacecraft, like the shepherd to look after the same swarm. Over the past century, global temperatures increased significantly in the next one hundred years this trend will continue, many studies have confirmed that Earth's temperature will increase in the next few centuries 1 to 20 degrees Fahrenheit, sea level was rising, a number of coastal cities will cease to exist. Some scientists have pointed out that the reduction of sunlight, the Earth temperature will decrease, and some ground or space systems can achieve this goal. However, scientists point out that it is still impossible to calculate how much the Earth can absorb light in the end, how much sunlight is reflected back into space, which is a key step in the implementation of the plan. U.S. scientists study showed that the activities of the ancient farmers had to make the world to avoid entering a new ice age. This result shows that human-induced global warming is not a new phenomenon, it can last thousands of years. British "Observer" recently quoted the researchers as saying that cutting down trees and cultivated fields of prehistoric farmers first piece of the earth atmospheric methane and carbon dioxide and other greenhouse gases changed a lot, so the gradual rise in global temperatures. University of Virginia Professor Wei Qian Ruddiman said: "If it was early greenhouse gases caused by agricultural activities, the current global temperature is probably still the glacial period the temperature." Research shows that if there is no human intervention, the earth will be lower than it is now 2 degrees Celsius, the spread of ice sheets and glaciers will affect many parts of the world. Human emissions of some gases such as carbon dioxide, methane, chlorofluorocarbons and other functions with the absorption of infrared radiation, these gases are called "greenhouse gases." They abound in the atmosphere, as a cover to block the heat on the ground. Like "greenhouse", as the rise in surface temperature caused. Scientists call this "greenhouse effect." There is a saying: that the greenhouse effect is caused by global climate warming. This is nearly a hundred years scientists have studied the increase in carbon dioxide emissions associated with the temperature rise put forward. That control greenhouse gas emissions, global warming may be controlled to prevent damage to the ecological balance, agricultural variation, melting glaciers and other disasters occur. Of course, according to the modern environment, scientific research, the greenhouse effect and global warming-related climate gas, but also in further exploration. But people have indeed felt the global warming and abnormal, in this regard, scientists have suggested that control greenhouse gas emissions may be safe than sorry. Global warming for two reasons: the burning of coal, natural gas, generate significant greenhouse gases; indiscriminate felling of forests, making the decline in the ability to absorb carbon dioxide. The atmosphere and surface of the system like a huge "glass house", so that the surface has always maintained a certain temperature, produced for human and other organisms living environment. In this system, both to the atmosphere through which solar radiation reaches the ground, while the ground to prevent radiation from escaping, we have the atmosphere of this protective effect on the ground called the atmospheric greenhouse effect. Greenhouse gases as "greenhouse gases", which allows free passage of solar radiation, while absorbing the surface long-wave radiation emitted. These gases are carbon dioxide, methane, chlorofluorocarbons, ozone, nitrogen oxides and water vapor, the most important is carbon dioxide. Gradually over the past century the global climate is warming, with the same time, atmospheric levels of greenhouse gases also increased dramatically. Many scientists agree that emissions of greenhouse gases, many of the intensification of the greenhouse effect caused by the possible underlying causes of global warming. The main cause of global warming is nearly a century of human heavy use of fossil fuels (such as coal, oil, etc.), large amounts of carbon dioxide emissions and other greenhouse gases. Because of these greenhouse gases on the short-wave radiation from the sun with a high degree of permeability, while the long-wave radiation reflected from the earth is highly absorbent, but also invisible electromagnetic pollution, which is often said that the "greenhouse effect ", leading to global warming. The world's forests are divided into cold (northern) forests, temperate forests and tropical forest categories. According to experts, today's forest ecosystems, is the nature of evolution through 8000 years has been gradually formed. Today, all of the original forests have become a large-scale exploitation of the logging industry's goals. In the tropics, many of the forest is now gone in the past 50 years have been cut empty. Only from 1960 to 1990, there is more than 450 million hectares of tropical forest were engulfed, the total area of the world's tropical forests 20%; there are several million hectares of tropical forest deforestation, farmland reclamation and mineral extraction in the degradation. Moreover, the global illegal logging and illegal timber trading continues to increase, especially in developing countries with tropical forests and poor law enforcement in Russia and other countries. The international market demand for cheap wood products, has further worsened the situation. Intergovernmental Panel on Climate Change, according to climate model predictions, 2100 date, estimated that global temperatures will rise about 1.4 to 5.8 degrees Celsius (2.5 to 10.4 degrees Fahrenheit). According to this forecast, global temperature will occur over the past 10,000 years, there has never been a huge change, and thus the global environment and potentially significant impact.

What is global warming
Global warming refers to the period of time, the Earth's atmosphere and the phenomenon of rising ocean temperatures, mainly refers to the temperature rise caused by human factors. The reason is probably due to greenhouse gas emissions caused by excessive. Human burning of coal, oil, natural gas and trees, a large amount of carbon dioxide and methane into the atmosphere, warming the earth after that balance the carbon cycle, changing the Earth's biosphere energy conversion form. Since the industrial revolution, atmospheric carbon dioxide increased by 25%, far more than scientists can survey the past 16 years out of the entire record, and currently no signs of slowing down. Increase in atmospheric carbon dioxide emissions on global warming is caused by the root. International Energy Agency, a survey showed that the United States, China, Russia and Japan, global carbon dioxide emissions account for almost half of the total. Survey showed that U.S. carbon dioxide emissions in the world, per capita carbon dioxide emissions of about 20 tons of carbon dioxide emissions account for 23.7% of the global total. China's per capita carbon dioxide emissions of about 251 tons, accounting for 13.6% of the global total. 1, mainly due to global warming for nearly a century of human heavy use of fossil fuels (such as coal, oil, etc.), large amounts of CO2 emissions and other greenhouse gases. Because of these greenhouse gases on the short-wave radiation from the sun with a high degree of permeability, while the long-wave radiation reflected from the earth is highly absorbent, it is often said that the greenhouse effect ", leading to global warming. 2, scientists recently proposed a new concept that cosmic rays is one of the causes of global warming, he formed the lower atmosphere by changing the cloud of global temperature over the past 1,000 years schematic layer change the way the climate warming.

The consequences of global warming
1. Climate becomes warmer, glaciers melting, sea levels will rise, causing coastal wetlands, mangroves and coral reefs, loss of ecological groups, coastal erosion, the terrible consequences of global warming, sea water intrusion of fresh groundwater level along the coast, coastal land salinization, resulting in the coast, estuaries, bays natural environment balance, to the coastal ecological system disaster. 2. Water area increased. Too much evaporation, prolonged rainy season, floods are becoming more frequent. Chance of flooding being increased, subject to the extent and severity of storms increased dam shortened life expectancy. 3. Water temperature could have on the Antarctic Peninsula and the Arctic Ocean ice melt. Polar bears and walruses will be extinct. 4. Many islands will be without a trace; to malaria and other infectious diseases ... ... 5. Because there is the role of thermal inertia, the existing greenhouse gases will continue to affect our lives. " 6. Temperature increases will affect the person's birth, the activity of sperm decreases with increasing temperature ... .... Impact on the climate The more carbon dioxide and greenhouse gas emissions into the atmosphere caused the harm, no one can accurately describe the future there will be more serious? Scientists are estimating the hazards posed by climate change. Calculated at the current level of technology in 2004, atmospheric carbon dioxide in order to clarify the mechanism of formation and digestion, so you can discover how the greenhouse effect is produced. 2006 to accurately predict the result of global warming caused by rising sea levels. But to really understand all this until 2050. Clearly, scientists and politicians will not wait for the outcome before taking further control measures, the present observations and findings should have let the public know they are not to make people have to swallow the bitter fruit of 50 years since. Since the Earth since the formation of the greenhouse effect, it has been at work. Without the greenhouse effect, Earth's surface will be extremely cold, the temperature will drop to minus 20 ℃, oceans would freeze and life would not be formed. Therefore, we face the problem of the greenhouse effect is not there, but human beings through the burning of fossil fuels, a large amount of greenhouse gases into the atmosphere, causing the greenhouse effect the Earth's climate changed dramatically with the problem. What is the greenhouse effect will have impact? Since a large number of fossil fuel combustion and deforestation, resulting in concentrations of carbon dioxide in the Earth's atmosphere increases the greenhouse effect of gases such as carbon dioxide, in the past 100 years, global average surface temperature has increased by about 0.3-0.6 ℃, 2030 estimate may raise 1-3 ℃. When the world's average temperature increases 1 ℃, will produce great changes: sea level rise, mountain glaciers will retreat, snow area will be reduced. As global temperatures rise, it will lead to uneven rainfall, increased precipitation in some areas, while others decreased precipitation. Such as the Sahel region of West Africa from a serious drought since 1965; in North China since 1965, successive years of reduced rainfall, compared with the 50's, now that the precipitation has been reduced by 1 / 3 of water reduced by 1 / 2; of the area affected by drought every year about 4 million hectares, in normal years, the National Irrigation water 300 billion cubic meters a year, city water 6 billion cubic meters. As temperatures rise, in the past 100 years, global sea level per year 1 - 2 mm a rate increase is expected in 2050 will continue to rise 30-50 cm sea level, which would flood a large number of low-lying coastal land; In addition, climate change drought, low temperature and other climate disasters exacerbated, resulting in tens of billions each year over the world of dollars in economic losses. Melting glaciers In recent years, from Patagonia to the Swiss Alps glaciers because the "greenhouse" gas emissions and generally believed that the Antarctic glaciers melting faster while the case of the greenhouse effect was observed. In South Asia, the question is not whether the melting of glaciers, but how fast melting? Although many adverse effects of global warming may be to the 21st century will become very serious, but in Nepal, India, Pakistan, China and Bhutan to the glacial melt water may cause trouble to the people soon. International Commission on Snow and Ice (ICSI) in a research report: "the rate of Himalayan glaciers retreat faster than any other world. If the current rate of melting continues, the glaciers disappeared in 2035 is very likely large. " Cypriot head of the International Commission on Snow and Ice justice 德哈斯内恩 said: "Even if the glaciers melt water from 60 to 100 years in the dry, the impact of this ecological disaster will breadth is shocking." Ganges River in the Himalayan region of Shandong Department of melting glaciers is the most serious, those located in the "Roof of the World" on Kashmir, from Bhutan to the fastest glacial retreat. Up to 3 miles to Barr ng glaciers, for example, this glacier is 40 million - 5000 million years ago the Indian subcontinent collided with the Asian continent to form one of the many glaciers, since 1990, it has a half-back miles. After the 1997 sub-Arctic cold in winter, the scientists had expected that the glaciers will be extended, but it further in the summer of 1998 but retreated. Rampant diseases New Harvard University Institute of disease and disease recurrence Paul. By Epstein noted that plants with the snow line and move the plants around the world peak in the last shift. With the warming of mountain peaks, high altitude environment at more favorable for mosquitoes and Plasmodium are carried by such microbes. West Nile virus, malaria, yellow fever and other tropical diseases since 1987 in the United States, Florida, Mississippi, Texas, Arizona, California and Colorado and other places have erupted, repeatedly confirmed by the experts on climate warming, some of the colder regions of tropical diseases will spread scientific inference. New Ice Age Another global warming the more surprising results of a study by melting Arctic ice, increased precipitation, as well as changing the type of wind, a lot of fresh water is imported North West, which caused damage to the Gulf Stream. It is these warm surface water from the warm Caribbean Sea to the north-west Europe, and to the formation of a warm climate in Europe. Once the Gulf Stream has been cut off due to global warming, the temperature in northwestern Europe could fall as much as 5-8 ℃, Europe may face a new ice age! The study is located in Aberdeen, Scotland, analyzed the marine laboratory located in the Blue Sea Islands to the sea between the Faroe Islands in 1893 to 1.7 million times since the salinity measurements obtained. In each of the past 20 years, the flow of deep water salinity in southern become smaller, lower and lower concentrations, suggesting that there is more to import water from the Atlantic Ocean north of the region. These new data for the first time fully proved in about 3 years ago, German scientists designed a computer model. Mark Twain once said, the weather characteristics of the most touching is that it's changing. More than one century later, we are still accurate prediction of weather conditions for the efforts to control climate has little effect; however, damage to the environment is unprecedented. 1. Ecological First of all, global warming, sea level rise, precipitation redistribution, changes in the current world climate patterns; Secondly, the impact of global warming and damage the food chain, food chain, leads to more severe natural consequences. For example, there is a migratory bird, flew from Australia every year in northeast China over the summer, but because of global warming to rising temperatures in northeast China, the summer extension of time for the bird to leave the Northeast corresponding warming, time to return to the Northeast accordingly delayed. This resulted in a kind of migratory birds eat insects flooded and destroyed large areas of forest. In addition, the increase in extreme events on the environment, such as drought, floods and so on. 2. Political Limit carbon dioxide emissions is tantamount to limiting the consumption of energy is bound to produce the world the impact of conditionality. Should be in developing countries "emission reduction", or in the developed countries "emission reduction" has become the focus of national discussion. Greenhouse gas emissions in developing countries increased in 2013 after the "reduction" problem is bound to focus on developing countries. Stop global warming on scientific issues will inevitably lead to "North-South relations" problem, so that the climate issue into an international political issue. 3. Climate Global warming to the mainland, especially the increase of precipitation in high latitudes, decreasing precipitation in some parts of Africa. Some areas of extreme weather and climate events (El Niño, droughts, floods, thunderstorms, hail, storms, high temperatures and dust storms, etc.) to increase the frequency and intensity. 4. Ocean As global temperatures rise, ocean substantial increase in the amount of evaporation of water vapor, adding to warming. The overall heat capacity of the ocean but also inhibit the reduction of global warming. In addition, since the release of the ocean to the atmosphere of excessive carbon dioxide, so the real culprit is the plankton in the ocean community. 5. Crops Global warming effects on crop growth and pros and cons. First, the global temperature changes directly affect the global water cycle, so that droughts or floods in some regions, leading to crop failures, and the temperature is not conducive to seed growth. Second, increases in precipitation, especially in the arid region will actively promote the growth of crops. With global warming, increased carbon dioxide levels will also promote the photosynthesis of crops to improve yield. 6. Human Health (1) a direct result of global warming occur in parts of the summer ultra-high temperature, heart disease and respiratory diseases caused every year claimed the lives of many people, among which the newborns and the elderly are most at risk. (2) global warming, ozone concentration, ozone is very low in the dangerous contaminants that can damage people's lung tissue, trigger asthma or other lung disease. (3) Global warming will cause some infectious diseases.

How to slow global warming
Global warming the Earth has changed in many aspects, some of which change itself also inhibit global warming trend. First, global warming make the earth part of the ice and snow melt, the global increase in the total liquid water. The liquid water than the forest giant hot air than ice, heat due to the increased greenhouse effect due to increase in the total liquid water on Earth without the water temperature increased significantly, due to the increased greenhouse effect heat though the rocks on the planet , and land temperatures increased significantly, but because of its liquid water on the earth heat exchange occurs, so that the whole earth was no longer significant warming, to some extent off_set_ the greenhouse effect, delaying the melting of snow and ice on Earth. Second, global warming green plants on the planet strong growth, photosynthesis over global warming before its absorbing more carbon dioxide (the main part of the greenhouse gases), fixed part of the greenhouse gases, so that this part will not stop the world from greenhouse gases out on the heat radiation, but also to some extent off_set_ the greenhouse effect. Scientists have proposed a bold idea, to build around the Earth or a spacecraft composed of small particles of artificial space ring, covered the tropical sun, Earth's temperature regulation. However, some opponents argue that this idea will certainly be some side effects, one can effectively scatter the sunlight will make the particles with each of us have become, and the full moon night sky as bright; and budget for this program will be alarmingly high, may reach 6 trillion to 200 trillion U.S. dollars, and even the world's most abundant funds NASA research institutions can not afford, if the scattering particles into the space ship, then, may be less budget, dropped to 500 billion U.S. dollars estimated to be around. Since the birth of earth, air temperature was down several times, solar radiation, the clouds and greenhouse gases and other factors have been or are affecting our climate. If the earth around a particle or a spacecraft on the composition of the "belt", then there will be a shadow over the equator, to deploy these particles, they must use some special control spacecraft, like the shepherd to look after the same swarm. Over the past century, global temperatures increased significantly in the next one hundred years this trend will continue, many studies have confirmed that Earth's temperature will increase in the next few centuries 1 to 20 degrees Fahrenheit, sea level was rising, a number of coastal cities will cease to exist. Some scientists have pointed out that the reduction of sunlight, the Earth temperature will decrease, and some ground or space systems can achieve this goal. However, scientists point out that it is still impossible to calculate how much the Earth can absorb light in the end, how much sunlight is reflected back into space, which is a key step in the implementation of the plan. U.S. scientists study showed that the activities of the ancient farmers had to make the world to avoid entering a new ice age. This result shows that human-induced global warming is not a new phenomenon, it can last thousands of years. British "Observer" recently quoted the researchers as saying that cutting down trees and cultivated fields of prehistoric farmers first piece of the earth atmospheric methane and carbon dioxide and other greenhouse gases changed a lot, so the gradual rise in global temperatures. University of Virginia Professor Wei Qian Ruddiman said: "If it was early greenhouse gases caused by agricultural activities, the current global temperature is probably still the glacial period the temperature." Research shows that if there is no human intervention, the earth will be lower than it is now 2 ℃, the spread of ice sheets and glaciers will affect many parts of the world. Human emissions of some gases such as carbon dioxide, methane, chlorofluorocarbons and other functions with the absorption of infrared radiation, these gases are called "greenhouse gases." They abound in the atmosphere, as a cover to block the heat on the ground. Like "greenhouse", as the rise in surface temperature caused. Scientists call this "greenhouse effect." There is a saying: that the greenhouse effect is caused by global climate warming. This is nearly a hundred years scientists have studied the increase in carbon dioxide emissions associated with the temperature rise put forward. That control greenhouse gas emissions, global warming may be controlled to prevent damage to the ecological balance, agricultural variation, melting glaciers and other disasters occur. Of course, according to the modern environment, scientific research, the greenhouse effect and global warming-related climate gas, but also in further exploration. But people have indeed felt the global warming and abnormal, in this regard, scientists have suggested that control greenhouse gas emissions may be safe than sorry. Global warming for two reasons: the burning of coal, natural gas, generate significant greenhouse gases; indiscriminate felling of forests, making the decline in the ability to absorb carbon dioxide. The atmosphere and surface of the system like a huge "glass house", so that the surface has always maintained a certain temperature, produced for human and other organisms living environment. In this system, both to the atmosphere through which solar radiation reaches the ground, while the ground to prevent radiation from escaping, we have the atmosphere of this protective effect on the ground called the atmospheric greenhouse effect. Greenhouse gases as "greenhouse gases", which allows free passage of solar radiation, while absorbing the surface long-wave radiation emitted. These gases are carbon dioxide, methane, chlorofluorocarbons, ozone, nitrogen oxides and water vapor, the most important is carbon dioxide. Gradually over the past century the global climate is warming, with the same time, atmospheric levels of greenhouse gases also increased dramatically. Many scientists agree that emissions of greenhouse gases, many of the intensification of the greenhouse effect caused by the possible underlying causes of global warming. The main cause of global warming is nearly a century of human heavy use of fossil fuels (such as coal, oil, etc.), large amounts of carbon dioxide emissions and other greenhouse gases. Because of these greenhouse gases on the short-wave radiation from the sun with a high degree of permeability, while the long-wave radiation reflected from the earth is highly absorbent, but also invisible electromagnetic pollution, which is often said that the "greenhouse effect ", leading to global warming. The world's forests are divided into cold (northern) forests, temperate forests and tropical forest categories. According to experts, today's forest ecosystems, is the nature of evolution through 8000 years has been gradually formed. Today, all of the original forests have become a large-scale exploitation of the logging industry's goals. In the tropics, many of the forest is now gone in the past 50 years have been cut empty. Only from 1960 to 1990, there is more than 450 million hectares of tropical forest were engulfed, the total area of the world's tropical forests 20%; there are several million hectares of tropical forest deforestation, farmland reclamation and mineral extraction in the degradation. Moreover, the global illegal logging and illegal timber trading continues to increase, especially in developing countries with tropical forests and poor law enforcement in Russia and other countries. The international market demand for cheap wood products, has further worsened the situation. Intergovernmental Panel on Climate Change, according to climate model predictions, 2100 date, estimated that global temperatures will rise by about 1.4 ~ 5.8 ℃ (2.5 ~ 10.4 degrees Fahrenheit). According to this forecast, global temperature will occur over the past 10,000 years, there has never been a huge change, and thus the global environment and potentially significant impact. Global warming propaganda cartoons to our call to protect our common home, please conserve every drop of fresh water. In order to protect our common home, planting trees like him to slow down the desertification. In order to protect our common home, please do not give one convenient bag. In order to protect our common home, Please do not throw used batteries. In order to protect our common home, reduce carbon dioxide emissions. In order to protect our common home, please everyone take good care of flowers and trees. In order to protect our common home, please actively promote environmental protection. In order to protect our common homeland, protect our common homeland. I remember the picture internationally renowned author Barbara. Cooney (Barbara Cooney) of a masterpiece "flower lady (Miss Rumphius)", the story of the little girl to her grandfather said, I grew up, to travel to far away, and then, I want to live in the sea . Her grandfather said that these are good ... ... but you have to do one thing: make the world more beautiful. So, the little girl grew up, choose a beautiful beach lined with purple and blue lentil flower, landscaping Earth. "Who say you can not change the world?" (Who says you can not change the world), you? Particularly in the April 22 Earth Day, the anniversary of the international yard, you choose how? ◎ Food: First, the April 22 Earth Day vegetarian day. (Livestock consume large amounts of Valley, beans, and consume large amounts of precious water; for grazing cattle and pig, the expense of virgin forest, causing the greenhouse effect. Second, eat (at home, cooking, eating just the right weight, take leftovers home) Third, the fasting day (Experience the taste of green body) Fourth, refused to use styrofoam, and asked the restaurant, or coffee shop using paper cups (Styrofoam is a carcinogen, which also destroy the ozone layer protecting the earth. Styrofoam coffee cups, buffet dishes, a few hundred years After the garbage or to continue to pollute the environment.) Five, refused to buy high mountain tea, mountain vegetables (high mountain tea, cold vegetables, so that Taiwan's high deforestation, destruction of mountain soil and water conservation, can not play the function of storing water, and heavy use of pesticides and fertilizers, pollution of water and reservoir ecology.) ◎ clothing: First, the understanding of clothing from: 1. Buy natural cotton, hemp and other natural materials (organic in nature), be recycled. 2. In accordance with standard washing clothes to buy clothes and maintenance to extend the life of clothes. Second, the demand for the decision, according to: the number of laundry, home size, lifestyle, financial situation to determine the four elements of the frequency buy clothes, try to control is good, not excessive (not heavy weight). Third, new clothes to wear tips: 1. Self-awareness: body, skin color, lifestyle considerations. 2. To find the popular focus on: such as length, color, etc., usually in a simple, good cut (D cut) the best performance out of the interaction between people and material. 3. Accessories for small size, changing, good effect, collecting easier, such as scarves, pins, belts, small amount of clothing that is reliable and clothing accessories to highlight the artistic effect. ◎ live: One, the use of second-hand furniture (whether to buy a house, rent an apartment, more use of second-hand furniture, recycling can save resources, if in the office, the community, organizing regular second-hand thrift exchange network flea market, the environment, and can be mutual aid, promote friendship among people.) Second, and more to do with the tree planting home decoration (home decoration do not make transitional arrangements should be simple, natural principle. Home layout does not necessarily man-made material, may wish to use the ecology of natural materials. A variety of flowers and potted plants, the best use of indigenous species, the home stay in the courtyard of the natural soil, use less cement, or hard of pavement.) Third, use containers filled with water, washing fruits and vegetables, dishes, brush your teeth, wash your face, to save precious water (China is the world's water shortage in the country ranked eighteenth position, the current severe drought in southern Taiwan have been caught, but our But with demand for water has reached the standard of the Republic of China for 100 years. France's current water conservation promotion policy is "a bath once a week"; If our water consumption continues to worsen, we will face the same situation. Fourth, the room supply, centralized air-conditioning use (as little as possible to open an air-conditioned room, who came from a centralized office as much as possible, reduce air-conditioning, electric usage). ◎ line: First, take the stairs, no elevator (living in the building, whether in the office or home, if you do not hurry, we might try to walk car, try not to take the elevator, the stairs instead, saving energy, but also sports and fitness .) Second, go out and more walking, cycling, using public transportation, less driving and riding motorcycles. ◎ Others: First, if your pet, please refuse to buy dogs and cats pest control loop (when you discard the cats and dogs pest control loop, the pesticide composition of the Earth's destruction is very strong, and the animal's body would cause serious harm). Second, refuse to buy products with the animal experiment (a lot of unnecessary animal cruelty program, in addition to a waste of taxpayer's taxes, resulting in natural genetic inheritance issues, the ecological environment of Taiwan is also a major health problem and there is not much help and improvement. Third, refusing to take or use the balloon (the balloon is very difficult to break down the chemicals, which caused serious pollution on the planet, in addition, when the balloons drift away, may lead to wildlife (eagles, whales or sea turtles, eating the phenomenon of death). (Note: China from June 1, 2008 onwards, in all supermarkets, shopping malls, markets and other retail establishments to implement the system of paid use of plastic shopping bags, carry heavy consumer advocacy cloth tape, repeat basket, reducing the use of plastic bags.) Please protect the environment, do not destroy nature

"Time" magazine lists 50 measures
Some only require little effort. Electrical articles Turn off the computer - Screen saver does not mean that environmental protection procedures. U.S. Department of Energy data show that 75% of households have electricity consumption in the television, computer and audio, etc. remain on standby. Average of a desktop computer (not including monitor) consumes 60 to 250 watts per day. If you use a computer 4 hours a day, other time off, then the annual savings of $ 70 for you, and can reduce carbon dioxide emissions by 83%, 63 kg per year. Care water heaters - Improve the thermal efficiency of household does not mean spending hours on the nest in the attic insulation coating. In fact, very simple method, such as your home's water heater to a warm "hug" - pack a layer of insulation blankets, the cost of 10-20 U.S. dollars only, but you can make your home an annual reduction of 250 pounds (113 kg combined) in carbon dioxide emissions. Most water heaters use 5 years later, the internal insulation will deteriorate, waste heat, waste of energy. So, touch the surface water heater, if can feel warm, give it to buy pieces of "coat" it. Travel articles Make the workplace a little closer to home - Drive to work, a waste of time waste of energy. It appears that the only solution is moving to the office next door. But less so for the office closer to home a little bit? This concept is called "the recent exchange." If a company within the coverage area in the metro line has many branches, this concept can be a very good use and play a role. Seattle, Washington, software development engineers 吉恩马林斯 designed a project to help the company to work close to the staff accommodation, a substantial saving in time spent on the commute. Mullins in the Starbucks, Key Bank National Bank of America, Boeing and Seattle City Fire Department investigation found that only 4% of the firefighters working at the nearest fire station, and some firefighters to be 145 miles one way to work (together 233.3 km); Boeing's Puget Sound in Washington state's 80,000 employees, the sum of daily commute can be 85 laps around the earth. The project uses Mullins, Key Bank Bank branch employees to work a number of distance reduced by 69%. For employees, time to escape the congestion at rush hour is the best reward. The same pay, same work, who do not want to spend less time on the road? Election bus - U.S. carbon dioxide transport carbon dioxide emissions account for more than 30% reduction of such emissions is one of the best way: take the bus. American Public Transportation Association, said public transport annual savings of about 14 billion gallons (5,299,600,000 liters combined) of natural gas, which means that can reduce 150 million tons of carbon dioxide emissions. Unfortunately, the United States only city of the district public transportation, 88% of the cars still bear the journey. Now more feasible approach is to establish a bus rapid transit system, in particular long-haul passenger load on the highway professionals. While carbon emissions than buses more than trains, but through the use of hybrid fuel or compressed natural gas engines to reduce emissions. American Institute of breakthrough technology, a study last year showed that a medium-sized city bus rapid transit system in 20 years time to reduce the 654,000 tons of carbon dioxide emissions. Pay bills online - To avoid driving to the bank on pay day, unnecessary emissions of carbon dioxide, require employers to pay directly to your designated account. In the online banking and bill operation, not only to save the trees, but also to reduce the energy consumption of transport of paper documents. According to Javelin Strategy research organization estimates that if each household U.S. households are aware of this, personally use the network pay the bills, and that 1.6 billion tons per year will reduce paper consumption and 210 million tons of greenhouse gas emissions. That online payment security problems? Do not worry. Ignore those "phishing" e-mail personal information, monitor unauthorized agencies who sent the bill, identify problems and timely reporting, your credit card will not have been "attacked." Food and clothing articles Off his tie - The summer of 2005 in the Japanese business community can be described as "cool." White-collar workers had ripped off their trademark dark blue business wear, put on light-colored clothes, open collar. This is made by the Government of Japan as part of efforts to conserve energy. That summer, the temperature of the Government Office has remained at 28 degree Celsius. That tailors the policy confusion. But the whole summer, thus reducing carbon dioxide emissions in Japan 79,000 tons. Clothesline hanging roots - Feeding a sheep, sheep shearing, spinning, weaving, tailoring ... ... Even so, your clothes may not be environmentally friendly, and ultimately also depends on the way to your laundry. Manufacturing Institute of the University of Cambridge's latest research shows that 60% of clothes "energy" in the release of cleaning and drying process, such as a T-shirt "life" can discharge 9 pounds (4.0824 kg combined) oxygen compounds . Note that the laundry with warm water, rather than using hot water; If you want to wash clothes more, _select_ a large capacity washing machine, rather than using multiple small capacity; efficient washing machines use as much as possible, because a new washing machine The energy-consuming one quarter of the old washing machine. Wash clothes, hanging on the clothesline to dry naturally, do not put in the dryer. This way, you can reduce 90% of the total carbon dioxide emissions. Discarded steak - Which should be responsible for global warming, car or "Big Mac"? Believe it or not, in fact, meat pie. According to FAO, a report published last year, the global meat processing industry emissions of greenhouse gases, global greenhouse gas emissions account for 18%, even more than transportation. The main greenhouse gases in the biogas from manure and nitrous oxide. Fertilizer and biogas is "a natural result of bovine digestion." Gas on the impact of global warming is 23 times the carbon, the influence of nitrous oxide is 296 times more carbon. Earth 15 million of domestic cattle and bison, 1.7 billion sheep and goats. Their numbers are growing rapidly. Global meat production is expected between 2001 and 2050 double. Think of the animal husbandry, transportation and sale of the energy consumed in the process, a plate 16 ounces (453.592 grams combined) of the steak like a buzzing in the front buzzer. University of Chicago study shows that if you turn to be a vegetarian, will reduce annual carbon dioxide emissions approximately 1.5 tons. Living articles Species of a bamboo fence - A beautiful bamboo fence can be. Fast growth of bamboo, some types of bamboo can grow 1 foot a day (combined 0.3048 meters) or more. Therefore, compared with the rose family plant, it can absorb more carbon dioxide. Most homeowners fear that bamboo grows fast and be limited. Actually, this reduces the bamboo as a function of carbon absorber. Open a window - An American produces about 25 tons of carbon dioxide each year. Most of the carbon dioxide from the family. How to reduce this number? There are some simple and effective method: open a window to replace the indoor air; in the summer air conditioning, a slight increase in temperature a few degrees lower in winter several times; the doors and windows blocked strict; the walls and ceilings for insulation treatment; and other dishes Machine wash filled; install a small shower flow; with warm water or cold water laundry; lower the thermostat on the heater device. Thus, until the end of the year, your house will only discharge 4,000 pounds (1814.4 kg combined) carbon dioxide. Living in China Replaced with energy-saving lamps - Family favorites, energy experts, non-compact fluorescent lamps (CFL) is none other than. The compact fluorescent was born in the mid 90s of last century, although the price is higher than ordinary incandescent bulbs, 3 to 5 times more expensive, but consume only a quarter of the latter, and life in general up to several years. In addition, compact fluorescent lamps also have the advantage that it does not flicker in the opening moments. Reject the use of plastic bags - Supermarket plastic shopping bags, the last is generally used as a waste landfilling. Globally each year consumes more than 500 billion plastic bags, of which only less than 3% recyclable. By polyethylene bags and buried thousands of years after the time required to achieve biodegrade, even during the harmful greenhouse gases. Reduce plastic bag pollution solution is to bag or bags made from biodegradable plant materials to replace plastic bags. When next to the grocery store, do not forget to bring bags. Organize green wedding - Wedding day, though not prevent global warming, but you can choose to reduce carbon emissions. No matter where the celebrations, you can buy locally produced wine or beer, custom wedding cakes from local bakeries, the use of the season rather than imported flowers, wearing a rented gown, the use of recycled paper, which can reduce carbon dioxide ... ... emissions. This is your wedding gift to this planet.

What is global warming (global warming)
Global warming refers to the period of time, the Earth's atmosphere and the phenomenon of rising ocean temperatures, mainly refers to the temperature rise caused by human factors. The reason is probably due to greenhouse gas emissions caused by excessive. Nearly 100 years, global average temperature has gone through warm → cold → cold → warm twice fluctuations, the overall look for the upward trend. Into the eighties, the global temperature increased significantly. Human burning of coal, oil, natural gas and trees, a large amount of carbon dioxide and methane into the atmosphere, warming the earth after that balance the carbon cycle, changing the Earth's biosphere energy conversion form. Since the industrial revolution, atmospheric carbon dioxide increased by 25%, far more than scientists can survey the past 16 years out of the entire record, and currently no signs of slowing down. Increase in atmospheric carbon dioxide emissions on global warming is caused by the root. International Energy Agency, a survey showed that the United States, China, Russia and Japan, global carbon dioxide emissions account for almost half of the total. Survey showed that U.S. carbon dioxide emissions in the world, per capita carbon dioxide emissions of about 20 tons of carbon dioxide emissions account for 23.7% of the global total. China's per capita carbon dioxide emissions of about 251 tons, accounting for 13.6% of the global total.

The consequences of global warming
1. Climate becomes warmer, glaciers melting, sea levels will rise, causing coastal wetlands, mangroves and coral reefs, loss of ecological groups, coastal erosion, the terrible consequences of global warming, sea water intrusion of fresh groundwater level along the coast, coastal land salinization, resulting in the coast, estuaries, bays natural environment balance, to the coastal ecological system disaster. 2. Water area increased. Too much evaporation, prolonged rainy season, floods are becoming more frequent. Chance of flooding being increased, subject to the extent and severity of storms increased dam shortened life expectancy. 3. Water temperature could have on the Antarctic Peninsula and the Arctic Ocean ice melt. Polar bears and walruses will be extinct. 4. Many islands will be without a trace; 5. Because there is the role of thermal inertia, the existing greenhouse gases will continue to affect our lives. " 6. Temperature increases will affect the person's birth, the activity of sperm decreases with increasing temperature ... .... 7. The original ecosystem changes. 8. To the production areas, such as: agriculture, forestry, animal husbandry, fisheries and other departments ... ... 9, malaria and other infectious diseases will be ... ... by extreme weather and climate to climate events (El Niño, droughts, floods, heat waves, etc ... ...), expand the outbreak of the epidemic, harmful to human health ... ... Impact on the climate The more carbon dioxide and greenhouse gas emissions into the atmosphere caused the harm, no one can accurately describe the future there will be more serious? Scientists are estimating the hazards posed by climate change. Calculated at the current level of technology in 2004, atmospheric carbon dioxide in order to clarify the mechanism of formation and digestion, so you can discover how the greenhouse effect is produced. 2006 to accurately predict the result of global warming caused by rising sea levels. But to really understand all this until 2050. Clearly, scientists and politicians will not wait for the outcome before taking further control measures, the present observations and findings should have let the public know they are not to make people have to swallow the bitter fruit of 50 years since. Since the Earth since the formation of the greenhouse effect, it has been at work. Without the greenhouse effect, Earth's surface will be extremely cold, the temperature will drop to minus 20 ℃, oceans would freeze and life would not be formed. Therefore, we face the problem of the greenhouse effect is not there, but human beings through the burning of fossil fuels, a large amount of greenhouse gases into the atmosphere, causing the greenhouse effect the Earth's climate changed dramatically with the problem. What is the greenhouse effect will have impact? Since a large number of fossil fuel combustion and deforestation, resulting in concentrations of carbon dioxide in the Earth's atmosphere increases the greenhouse effect of gases such as carbon dioxide, in the past 100 years, global average surface temperature has increased by about 0.3-0.6 ℃, 2030 estimate may raise 1-3 ℃. When the world's average temperature increases 1 ℃, will produce great changes: sea level rise, mountain glaciers will retreat, snow area will be reduced. As global temperatures rise, it will lead to uneven rainfall, increased precipitation in some areas, while others decreased precipitation. Such as the Sahel region of West Africa from a serious drought since 1965; in North China since 1965, successive years of reduced rainfall, compared with the 50's, now that the precipitation has been reduced by 1 / 3 of water reduced by 1 / 2; of the area affected by drought every year about 4 million hectares, in normal years, the National Irrigation water 300 billion cubic meters a year, city water 6 billion cubic meters. As temperatures rise, in the past 100 years, global sea level per year 1 - 2 mm a rate increase is expected in 2050 will continue to rise 30-50 cm sea level, which would flood a large number of low-lying coastal land; In addition, climate change drought, low temperature and other climate disasters exacerbated, resulting in tens of billions each year over the world of dollars in economic losses. Melting glaciers In recent years, from Patagonia to the Swiss Alps glaciers because the "greenhouse" gas emissions and generally believed that the Antarctic glaciers melting faster while the case of the greenhouse effect was observed. In South Asia, the question is not whether the melting of glaciers, but how fast melting? Although many adverse effects of global warming may be to the 21st century will become very serious, but in Nepal, India, Pakistan, China and Bhutan to the glacial melt water may cause trouble to the people soon. International Commission on Snow and Ice (ICSI) in a research report: "the rate of Himalayan glaciers retreat faster than any other world. If the current rate of melting continues, the glaciers disappeared in 2035 is very likely large. " Cypriot head of the International Commission on Snow and Ice justice 德哈斯内恩 said: "Even if the glaciers melt water from 60 to 100 years in the dry, the impact of this ecological disaster will breadth is shocking." Ganges River in the Himalayan region of Shandong Department of melting glaciers is the most serious, those located in the "Roof of the World" on Kashmir, from Bhutan to the fastest glacial retreat. Up to 3 miles to Barr ng glaciers, for example, this glacier is 40 million - 5000 million years ago the Indian subcontinent collided with the Asian continent to form one of the many glaciers, since 1990, it has a half-back miles. After the 1997 sub-Arctic cold in winter, the scientists had expected that the glaciers will be extended, but it further in the summer of 1998 but retreated. Rampant diseases New Harvard University Institute of disease and disease recurrence Paul. By Epstein noted that plants with the snow line and move the plants around the world peak in the last shift. With the warming of mountain peaks, high altitude environment at more favorable for mosquitoes and Plasmodium are carried by such microbes. West Nile virus, malaria, yellow fever and other tropical diseases since 1987 in the United States, Florida, Mississippi, Texas, Arizona, California and Colorado and other places have erupted, repeatedly confirmed by the experts on climate warming, some of the colder regions of tropical diseases will spread scientific inference. New Ice Age Another global warming the more surprising results of a study by melting Arctic ice, increased precipitation, as well as changing the type of wind, a lot of fresh water is imported North West, which caused damage to the Gulf Stream. It is these warm surface water from the warm Caribbean Sea to the north-west Europe, and to the formation of a warm climate in Europe. Once the Gulf Stream has been cut off due to global warming, the temperature in northwestern Europe could fall as much as 5-8 ℃, Europe may face a new ice age! The study is located in Aberdeen, Scotland, analyzed the marine laboratory located in the Blue Sea Islands to the sea between the Faroe Islands in 1893 to 1.7 million times since the salinity measurements obtained. In each of the past 20 years, the flow of deep water salinity in southern become smaller, lower and lower concentrations, suggesting that there is more to import water from the Atlantic Ocean north of the region. These new data for the first time fully proved in about 3 years ago, German scientists designed a computer model. Mark Twain once said, the weather characteristics of the most touching is that it's changing. More than one century later, we are still accurate prediction of weather conditions for the efforts to control climate has little effect; however, damage to the environment is unprecedented. 1. Ecological First of all, global warming, sea level rise, precipitation redistribution, changes in the current world climate patterns; Secondly, the impact of global warming and damage the food chain, food chain, leads to more severe natural consequences. For example, there is a migratory bird, flew from Australia every year in northeast China over the summer, but because of global warming to rising temperatures in northeast China, the summer extension of time for the bird to leave the Northeast corresponding warming, time to return to the Northeast accordingly delayed. This resulted in a kind of migratory birds eat insects flooded and destroyed large areas of forest. In addition, the increase in extreme events on the environment, such as drought, floods and so on. 2. Political Limit carbon dioxide emissions is tantamount to limiting the consumption of energy is bound to produce the world the impact of conditionality. Should be in developing countries "emission reduction", or in the developed countries "emission reduction" has become the focus of national discussion. Greenhouse gas emissions in developing countries increased in 2013 after the "reduction" problem is bound to focus on developing countries. Stop global warming on scientific issues will inevitably lead to "North-South relations" problem, so that the climate issue into an international political issue. 3. Climate Global warming to the mainland, especially the increase of precipitation in high latitudes, decreasing precipitation in some parts of Africa. Some areas of extreme weather and climate events (El Niño, droughts, floods, thunderstorms, hail, storms, high temperatures and dust storms, etc.) to increase the frequency and intensity. 4. Ocean As global temperatures rise, ocean substantial increase in the amount of evaporation of water vapor, adding to warming. The overall heat capacity of the ocean but also inhibit the reduction of global warming. In addition, since the release of the ocean to the atmosphere of excessive carbon dioxide, so the real culprit is the plankton in the ocean community. 5. Crops Global warming effects on crop growth and pros and cons. First, the global temperature changes directly affect the global water cycle, so that droughts or floods in some regions, leading to crop failures, and the temperature is not conducive to seed growth. Second, increases in precipitation, especially in the arid region will actively promote the growth of crops. With global warming, increased carbon dioxide levels will also promote the photosynthesis of crops to improve yield. 6. Human Health (1) a direct result of global warming occur in parts of the summer ultra-high temperature, heart disease and respiratory diseases caused every year claimed the lives of many people, among which the newborns and the elderly are most at risk. (2) global warming, ozone concentration, ozone is very low in the dangerous contaminants that can damage people's lung tissue, trigger asthma or other lung disease. (3) Global warming will cause some infectious diseases.
