1.Dramatic increase in the population factor is the dramatic increase in population in recent years leading to global warming one of the main factors.Besides,it has also seriously Adversity rib natural balance between ecological environment.So much of the population,only their annual emissions of carbon dioxide will be a staggering figure,and the results will direct derivative of the content of carbon dioxide in the atmosphere continued to increase,this form of carbon dioxide "greenhouse effect" will be a direct impact on the surface of the Earth climate change.
2.Atmospheric pollution factors Currently,the increasingly serious environmental pollution has posed a major global problem,but also lead to global warming one of the main factors.Now,with regard to the study of global climate change has been clearly pointed out that since the late 1990s from the Earth's surface temperature has started to rise.
3.Marine ecological deterioration factors Currently,sea level change is a constant upward trend,according to experts predicted that the middle of the next century,the sea level could rise 50 cm.And if they do not take measures will lead directly to the destruction of freshwater resources and pollution adverse consequences.In addition,the land-based activities have a large number of establishments toxic chemical wastes and solid wastes discharged into the ocean,and so constantly; occurred in a major Chinese seawater (leakage) as well as oil and other incidents caused by human activities in coastal areas,environmental degradation and so on that led to the destruction of water ecological environment a major factor.
4.Land by erosion,desertification,and other factors destruction
5.Factors sharp decline of forest resources in the world,due to natural or man-made factors causing forest area is substantially sharp decline.
6.Factors acid rain acid rain harm to the ecological environment has been the impact brought about by more and more world attention.Acid rain can damage forests,acid lakes,threaten biological.At present,the world of acid rain and more concentrated in Europe and North America,acid rain occurred in most developed countries,some developing countries,acid rain is also growing rapidly and development.
7.Accelerate the extinction of species on Earth biological factors is a valuable human resources,and biodiversity is mankind's survival and development.But now the biological species on Earth are being lost at unprecedented rates.
8.Water pollution factors According to the Global Environment Monitoring System show that the water quality monitoring project,the world about 10% of the water pollution monitoring,in this century,human beings are the sharp increase in water consumption,water pollution and the scale is constantly expanding,fresh water on the formation and the need for the one pair of contradictions.Clearly,the treatment of water pollution is very urgent and important.
9.Toxic waste pollution factors growing toxic chemicals not only for the survival of mankind pose a serious threat,but also for the ecological environment of the Earth's surface will also bring harm.
Global warming is a kind of "natural phenomenon". Because people burning of fossil to produce energy or mineral and the deforestation carbon dioxide from the burning of when greenhouse gas, because these greenhouse gases to the radiation from the sun highly visible through sex, and reflected on earth the highly longwave radiation absorption sex, can strongly absorbed the infrared radiation, ground is often say "greenhouse effect", causing global warming. The consequences of global warming, will cause the global to redistribution of rainfall, glaciers and permafrost melt, sea levels rising, which affects the balance of eco-system, more threatening human food supply and living environment.
People around the world may feel that the climate has been getting steadily warmer andwarmer in recent years. Places which used to be abundant in snowfall have frequentlyexperienced snowfreewinters.
Drought lasts longer in some dry areas.People findthat without air conditioners they could hardly work or fall asleep on hotter summer daysg.
The side effects of global warming are alarminS. A warmer global climate melts the icecaps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severestorms, hurricanes(想风).People suffer a lot from disasters relevant to global warming.
To stop global warming we should make immediate and continual efforts. We hope thesituation will soon change.Global warming catches and holds our concern, for it affects usand will affect our later generations. We cannot wait any longer. Do it right now.
Global warming is an increase in the earth's temperature due to fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while long wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.
There are many misconceptions about global warming. Some believe that pollution causes global warming, but the fact is global warming is the result of burning fossil fuels, coal, and oil that release carbon dioxide. Another misconception is nuclear power causes climate change. Nuclear power actually reduces emissions of carbon dioxide when used in place of coal. Some believe that global warming means that it will become warmer all over. The name is misleading because in some places, it will actually become colder. The majority of scientists believe global warming is a process underway and that it is human-induced.
The greenhouse gases are carbon dioxide, methane, and nitrous oxide. These gases occur naturally. The Earth uses those gases to warm its surface. Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, wood, and wood products are burned. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperatures would be 91.4 degrees cooler than the current temperatures. These gases trap heat and cause the greenhouse effect, rising global temperatures. Human activities add to the levels of these gasses, causing more problems. The burning of solid waste, fossil fuels, and wood products are major causes.
Automobiles, heat from homes and businesses, and factories are responsible for about 80% of today's carbon dioxide emissions, 25% of methane, and 20% of the nitrous oxide emissions. The increase in agriculture, deforestation, landfills, industrial production, and mining contribute a significant share of emissions too. The gases released into the atmosphere are tracked by emission inventories. An emission inventory counts the amount of air pollutants discharged into the atmosphere. These emission inventories are used by many organizations.
Global warming is a danger to a human's health. Its affect on climate can adversely affect humans. Plagues have been attributed to global warming. An increase in temperature can result in a longer life cycle for diseases or the agents spreading them. Living in a warm area makes egg production a quicker process. Global warming will lead to more precipitation, which enables infectious diseases to be more easily contracted and spread. Effects of global warming on human health might not be immediately detected.
Global warming can affect our future ability to obtain food. As climates change, plants and animals will change, leading to a change in the eating patterns of humans. An increase in precipitation is one result of global warming that could have devastating effects. First, the quality of crops would be affected by an increase in precipitation. Second, increasing rain could lead to an increase in soil erosion.
There are ways that you can help prevent global warming. Car pooling, auditing the energy in your home, buying fuel-efficient cars, and reducing the electricity in your home are ways to help prevent global warming. You can also write to your local congress representative or your local newspaper in response to stories, which say global warming, does not exist. Government authorities can help by passing laws to reduce emissions from factories. They can also form a treaty with other countries to legally bind limits on emissions of heat trapping gases.
The future of emissions damage depends on several factors, demographics, economics, technology, policies and institutional developments. Future predictions do not look good for this planet if nothing is done. Without the help of emissions control policies, CO2 levels are projected to be 30 -150% higher in 2100. Our renewable resources will be very limited. With cooperation from citizens and government officials, we can slow the effect of global warming by reducing greenhouse gas emissions.
