全球气候变暖是一种“自然现象”。由于人们焚烧贺唯化石矿物以生成能量或砍伐森林并将其焚烧时产生的二氧化碳等多种温室气体,由于这些温室气体对来自太阳辐射的可见光具有高度悔耐的透过性,而对地球反射出来的长波辐射具有高度的吸收性,能强烈吸收地面辐射中的红外线,也就是常说的“温室效应”,导致全球气候变暖。全球变暖的后果,会使全球降水量重新分配,冰川和冻土消融,海平面上升等,既危害自然生碧拍春态系统的平衡,更威胁人类的食物供应和居住环境。
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.
解题思路:可以从全球变暖的各种原因出发,如工业废气的排放、汽车尾气的排放等出发,用英语表示出啦,注意不要有语病,以下为例子:
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.
翻译:世界各地的人们可能感觉到,气候近几年已经越来越稳步暖和。降雪丰富的地方经常经历没有雪的冬天
Drought lasts longer in some dry areas.People findthat without air conditioners they could hardly work or fall asleep on hotter summer daysg.
翻译:一些干旱地区的干旱持续时间变长。人们发现,在炎热的夏天,没有空调,他们几乎无法工作或入睡。
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.
翻译:全球变暖的副作用。冰川融化,海平面上升。更重要的是,它扰乱天气模式,造宏纤成干旱,帆亏风暴,飓风。人们遭受的灾难与全球变暖有关的很多。
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.
翻译:为了阻止全球变暖我们应该立即采取并持续努力。我们希望这种情况将很快改变。全球气候变暖引起我们的关注态绝神,因为它影响到我们和我们的后代。我们不能再等了。现在就马上行动吧。
个人认为比较好的一篇
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.
