Global Warming At present, with the development of economies around the world may feel that the climate is becoming more and more warmer CO2 makes up about 70% of the greenhouse gases It is considered to be one of the greatest reasons of global warming It’s very serious, but many people can’t recognize that because the only think about themselves They don’t mind the climate becoming warmer They don’t mind the ice melting They don’t mind how many animals become extinct They don’t mind how many coastal cities become flooded They don’t mind…… They are wrong Global warming can have many strong influences for us For example: Global warming will make trouble with physiology People will become more easily ill and even breed new diseases People will pay more and more money for health care but more and more people die No amount of money or even the best doctors, wll not be able to save your life Even if you aren’t dying, you will feel sad and alone So many relatives and friends’ death will make you want to kill yourself Global warming will give the air and ocean huge power Thus making large or even super typhoons, hurricanes, tsunamis and other disasters Many houses will be destroyed Many place will flood We will be faced with more and more disasters, damning more and more money and life Rising temperatures will not only create higher sea level, but also will cause droughts Large-scale areas will become arid and thus food production will be less We will be without food People around the world will face food shortages and more and more war will happen for food If temperatures continue to rise, animals will come out of hibernation early, but will not have the food supply necessary to survive For example: Insects will eat a lot of forests and crops with no natural enemies Without forests, global warming will become more and more sercious, creating a vicious cycle No crops, means no human food The greatest of global warming is at ice age like in the movie “The Day After Tomorrow”, this is a scenario that take place So we must do something to avoid these things from happening First, we should use more and more clean energy and less oil and coal Second, we should go to work by bus or on foot instead of driving Third, we should plant more trees The most important point is we should make a habit of saving energy in everyday life 绝对是原创,你可以从我这400多字里选选改改,变成成自己的 第一段是原因,最后一段是因该怎么做,120词的话,你也可以就看看这两段

全球增温 引言 地球表面的温度及气候由太阳辐射决定,地球从太阳吸收的能量必须与地球和大气层向外释放的辐射能量相平衡,地球的温度才能稳定在一定范围内。为了维持这种平衡,地球上的外释能量(长波辐射)的一部份由辐射性的大气层气体(即温室气体)吸收并再反射回地球,进而减少向外层空间的能量净排放,这就是温室效应。藉著此种自然的温室效应,维持地表之温度,是地球温暖化的原理。 温室效应所造成的影响 人类活动一方面大量排放二氧化碳,特别是自工业革命以来,矿物燃料使用量不断大幅度增加,另一方面,又大量地毁坏森林、草原,使地球正在不断地失去二氧化碳储备库,大气中温室气体的浓度正在迅速增加,使地球向外释放能量减缓,造成不正常的温室效应。近年来由于人类经济活动的快速成长,所制造之化学品及产生的空气污染,正以空前未有之速度改变大气的结构。其中特别是化石燃料燃烧后所产生之CO2气体,大量排放进入大气后,吸收地表之长波辐射,造成之人为温室效应使地表温度逐渐增加。 气候转变:「全球变暖」 温室气体浓度的增加会减少红外线辐射放射到太空外,地球吸取和释放辐射的份量要达至新的平衡,气候无可避免地被转变。这转变可包括‘全球性’的地球表面及大气低层变暖,因为这样可以将过剩的辐射排放出外。 地球表面温度的少许上升可能会引发其他的变动,例如:大气层云量及环流的转变。当中某些转变可使地面变暖加剧(正反馈),某些则可令变暖过程减慢(负反馈)。 不正常的温室效应是引起全球气候变化的一个重要原因,而最主要在于地球上过量的二氧化碳,过去100年地球表面温度已上升03~06,当然学术界对此还有分歧,但多数人认为,全球变暖将给人类造成极严重的社会问题。 参考:resourcesemb/biology/english/images/environment/rainbow 海平面升高 不正常的温室效应的直接危害在于它使全球的气温升高。二氧化碳浓度增加一倍,将会使全球平均温度增加15~7℃,高纬度地区增加4~10℃,这样迅速升高的温度将会引起地球上的冰川融化,导至海洋平面上升,使许多沿海城市遭受灭顶之灾。 假若‘全球变暖’正在发生,有两种过程会导致海平面升高。第一种是海水受热膨胀令水平面上升。第二种是冰川和格陵兰及南极洲上的冰块溶解使海洋水份增加。预期到2100年时地球的平均海平面将有50厘米的升幅,其准确范围可在15至95厘米之间。 虽然,至目前为止,仅增加少许温度(过去100年只增加03℃至06℃),海平面则持续上升(10至15公分)。工业革命后CO2浓度增加28%,如果不限制温室气体的排放,根据现时的气候模式推算,在1990至2100年间全球的平均气温会上升2℃。这预计已考虑到大气层中悬浮粒子倾于对地球气候降温的效应与及海洋吸收热能的作用(海洋有较大的热容量)。但是,还有很多未确定的因素会影响这个推算结果,例如:未来温室气体排放量的预计、对气候转变的各种反馈过程和海洋吸热的幅度等等。估计这结果的准确范围介乎1℃至35℃之间。海平面将上升15至95公分,此种温室效应对于整个生态环境(包括地球、海洋与人类的经济、社会等)及全球气候,将有深远而不可知之影响。 对人类生活的潜在影响 经济影响 全球有超过一半人口居住在沿海100公里的范围以内,其中大部份住在海港附近的城市区域。所以,海平面的显著上升对沿岸低洼地区及海岛会造成严重的经济损害,例如:加速沿岸沙滩被海水的冲蚀、地下淡水被上升的海水推向更远的内陆地方。 农业影响 实验证明在CO2高浓度的环境下,植物会生长得更快速和高大。但是,‘全球变暖’的结果会影响大气环流,继而改变全球的雨量分布与及各大洲表面土壤的含水量。由于未能清楚了解‘全球变暖’对各地区性气候的影响,以致对植物生态所产生的转变亦未能确定。 海洋生态影响 沿岸沼泽地区消失肯定会令鱼类,尤其是贝壳类的数量减少。河口水质变咸会减少淡水鱼的品种数目,相反该地区海洋鱼类的品种也可能相对增多。至于整体海洋生态所受的影响仍未能清楚知道。 参考:resourcesemb/biology/english/images/environment/starfish 水循环影响 全球降雨量可能会增加。但是,地区性降雨量的改变则仍未知道。某些地区会有更多雨量,但有些地区的雨量可能会减少。此外,温度的提高会增加水份的蒸发,这对地面上水源的运用带来压力。 参考:resourcesemb/biology/english/images/environment/env7 参考:resourcesemb/biology/english/images/environment/falls02 全球气候变化纲要公约 联合国于1992年5月9日通过「气候变化纲要公约」(Framework Convention On Climate Change,FCCC),6月在里约的「地球高峰会议」上,l55个国家签署此公约,公约于l994年3月21日生效。目前已有170个缔约国认可。
据科学家周二说,因全球暖化引起而造成的疟疾、营养不良等效应,使得每年约有16万人丧生﹔到2020年,这个数字将可能倍增。 到本世纪末为止,全世界气温将提高摄氏2.4到4.4度。这种气温升高将使南北极冰山融化,一些大小岛屿会沉没,西伯利亚冻原区成为沼泽地。而发生生态变化引起水灾与旱灾等天然灾难!(最后人类玩完!科学家话2040年南北极冰山融哂!) 等阵我用我个后备ac帮你补充下问题!!
Global warming is the observed increase in the average temperature of the Earth’s atmosphere and oce in recent decades The Earth’s average near-surface atmospheric temperature rose 06 ± 02 °Celsius (11 ± 04 °Fahrenheit) in the 20th century The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities" The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced ponent of warming[2] They are released by the burning of fossil fuels
land clearing and agriculture
e and lead to an increase in the greenhouse effect The first speculation that a greenhouse effect might occur was by the Swedish chemist Svante Arrhenius in 1897
although it did not bee a topic of popular debate until some 90 years later [3] An increase in global temperatures can in turn cause other changes
including a rising sea level and changes in the amount and pattern of precipitation These changes may increase the frequency and intensity of extreme weather events
such as floods
droughts
heat waves
hurricanes
and tornados Other consequences include higher or lower agricultural yields
glacial retreat
reduced summer stream flows
species extinctions and increases in the ranges of disease vectors Warming is expected to affect the number and magnitude of these events; however
it is difficult to connect particular events to global warming Although most studies focus on the period up to 2100
warming (and sea level rise due to thermal expion) is expected to continue past then
since CO2 has an estimated atmospheric lifetime of 50 to 200 years [5] Only a all minority of climate scientists discount the role that humanity’s actions have played in recent warming However
the uncertainty is more significant regarding how much climate change should be expected in the future
and there is a hotly contested political and public debate over what
if anything
should be done to reduce or reverse future warming
and how to deal with the predicted consequences Because the limitation of words at 4000

Many people believe that human activity is causing the earth’s temperature to rise They say that this global warming will have dreadful consequences for our environment, such as drought and flooding,很多人都认为是人类活动导致了全球气温上升。他们说全球变暖会对我们的环境造成可怕的后果,如干旱和洪水。,What should governments do to help prevent global warming Give reasons for your suggestions, 该做什么来防止全球变暖呢?给出你建议的原因。,The earth’s temperature is rapidly changing As a result there has been a lot of climate change such as heat waves, droughts and floods Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere This could bee a disaster if governments do not act to help prevent global warming They can act in three ways; by supporting research, by making laws and by keeping the general public informed,地球的温度正在迅速改变。导致很多气候变迁,如热浪、干旱和洪水。科学家认为这是人类活动污染了地球的大气层的结果。如果 不采取行动来防止全球变暖的话,这可能会成为灾难。他们可以在三个方面上有所行动;支持研究,制订法律和保持公众知情。,Firstly, governments can support research For example, they should encourage panies to develop vehicles that cause less pollution They should also support alternative sources of electricity from wind and water rather than from oil and coal As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem,首先, 可以支持研究。例如,他们应该鼓励公司致力于汽车研发来减少污染。他们也应该支持来自风和水的电力替代能源,而不是来自石油和煤的电源。同时,他们应该主持会议来讨论温室气体排放的影响和可能解决问题的方案。,Secondly, they should make laws that limit the amount of greenhouse gases that panies can emit Private panies should be rewarded for following these laws They should also be punished for creating pollution,其次,他们应该制定法律限制公司发出的温室气体。私人公司应该因为遵循这些法律而得到奖励。他们也应该因为创造出污染而受到惩罚。,Finally, everybody is affected by global warming Therefore, it is important that governments involve individuals in the problem solving process For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water They should also encourage the public to recycle, and this should be pulsory for everyone Another way of saving energy is by public transport systems Governments should spend money on public transport to make it as easy as possible for the public to save energy,最后,每个人都是受到全球变暖的影响。因此, 和个人在解决问题的过程中是很重要的。例如,他们应该鼓励家庭尽可能多的节省能源,尽可能多的使用更高效的灯泡或少用热水。他们也应该鼓励公众回收,因为这对每个人来说都是必须的。另一种节约能源的方法是公共交通系统。 应该把钱花在公共交通使公众尽可能容易的节约能源。,In summary, it is clear that there are a lot of things that governments can do to prevent global warming They should involve panies, support scientists and encourage individuals to protect the pla,总之,很明确的,各国 可以做很多事情来防止全球变暖。他们应包括公司,支持科学家和鼓励个人保护地球。
Global warming has posed a serioud threat to the survival of humanity in the future Few people have realized that what our actions in this time mean more ato our future than ever More than ever before, the basic survival of our species is threatened by the danger of a no longer stable climate, which will destroy the regularity of almost every parts of our life As the studies conducted by massive gathering of scientists from all over the world points out, if the global average temperature rised over 2 degrees Celcius, global climate change will be self sustaining, at that point, a no longer stable climate will be the nightmare reality for every inhabitant of earth Although technology will probably play a key part in saving us from catastrophic troubles, one must not forget that it's technology that got us in this trouble in the first place In using the techniques developed by those advanced geo-physicists, the future of earth is risked more than climate change, as we have witnessed the unintended consequences of altering nature artificially Among all the green energy sources, residential solar power generation has the potency to save the world Few people knows that residential solar generated electricity will be enough for all the uses of the household, maybe even some extra selling back to local utilities China has the most potential in achieving a Solar Revolution, because China has the most potential in the suply and demand of solar power Suntect Power ( 尚德) , a remarkable Chinese solar company, offers high quality products in world standard in really low Chinese prices, a miraculous combination On the demand, a greatest number of residential owners in the world could possible want to get solar generated electricity If only the Chinese government comes up with the right incentives and subsidy to guide the Chinese solar market, it could be the tricker for a revolution that will save humanity from diasters and the change of fortune for China As the situation entails,everyone of us has responsiblities to protect the planet and ensure the survival of our species In daily life, try to fulfil the concept of reduce, reuse and recycle as much as one's ability allows and the concept of zero carbon emmission Using this as these ultimate goals and guidelines, one should try these actions in every means possible and proactively seek and learn better ways to live a green way of life More importantly, try to use as much green energy sources and products as economic situations allows, especially people in social position, to whom with greater resources lies greater responsibility to use those resources for the greater good
不好意思, 好像写太多了, (谁让我专门研究过这个问题呢)你自己精简吧 看看也有好处
全球变暖在未来构成了一个对人类生存构成严重威胁。很少有人意识到,在这个时候我们的行动意味着我们比以往任何时候更迹的未来。超过以往任何时候都对我们人类的基本生存受到威胁不再是一个稳定的气候,这将破坏我们生活的几乎每一个部件的规律性的危险。正如科学家所进行的大量研究,搜集世界各地的指出,如果全球平均气温升高超过2摄氏度,全球气候变化将是自我维持,在这一点上,一个稳定的环境将不再是现实的噩梦为每一个地球居民。虽然技术很可能会扮演拯救灾难困扰我们的一个重要组成部分,一决不能忘记,它的技术,在这首先给我们带来麻烦。在使用这些先进的地质物理学家研制的技术,对地球的未来是比气候变化更冒险,因为我们已经目睹了人为改变性质的意想不到的后果。在所有的绿色能源,住宅太阳能发电具有效力,以拯救世界。很少有人知道,住宅太阳能发电将足以为所有的家庭使用,甚至一些额外的售回本地公用事业。中国已经在实现一个最有潜力的太阳能革命,因为中国已在供应中最和太阳能电力需求的潜力。。 Suntect功率(尚德),一个了不起的中国太阳能公司,提供在中国的价格实在低,一个神奇的组合在世界标准的高品质的产品。在需求,最大的住宅业主可以在世界排名可能想要得到太阳能发电。我国政府如果只配备了适当的奖励和资助额,以指导中国太阳能市场,它可以是一次革命,它将从灾难中拯救人类
并为中国命运的变化。随着形势的需要,我们每个人都有职责,以保护地球,确保我们这个物种的生存。在日常生活中,努力实践概念的减少,再用和循环再造像一个人的能力大大允许和零碳排放的概念。利用这些最终目标的指引,我们应尽量在一切可能的手段,积极寻求更好的方式来学习和生活的绿色环保的生活方式这些行动。更重要的是,尝试使用如经济形势非常绿色能源来源和产品允许的话,尤其是在人的社会地位,更多的资源与人更大的责任在于利用好这些资源的更大
题目:Global warming more crisis
We are beautiful and great mother is ill and have a fever Because of our annual carbon dioxide emissions than the emissions of 2ppm, leading to the increased temperatures The latest data show, the global atmospheric concentrations of carbon dioxide and high growth rate, a higher than expected Scientists worry, earth may have lost the ability to absorb carbon dioxide
Because of our annual carbon dioxide emissions than the emissions of 2ppm, leads to the temperature rise
Newest data shows, global atmospheric concentrations of carbon dioxide and high growth rate, a higher than expected Scientists worry, earth may have lost the ability to absorb carbon dioxide :" we are in the midst of climate change point, this is not good news
1of our air conditioning high environmental temperature of 26 degrees to26 degrees is because, comparison of conditioning power The students you know electricity come from Is coal burning out a year we burn coal emissions of carbon dioxide number but a staggering number so everybody is in Shao Yong to reduce carbon dioxide emissions
2buy less unnecessary household appliances for electrical plant, production belongs to the industrial factory as I have mentioned, industrial plant is the emission of carbon dioxide up to, so, everyone must buy less unnecessary electrical appliances!
3, use less disposable batteries, because the production of battery factory, industrial plant Oh! And a battery can pollute one life needs water so, not only to reduce the use of disposable batteries and run out can not throw oh!
Protect environment is everyone's responsibility, this word is familiar today we not only should keep it in mind and action! Protect environment is to protect our mother earth and to our children a healthy green homes
多是多了点你参考一下吧下面是中文翻译
我们美丽而又伟大的母亲病了—发烧是因为我们每年排放的二氧化碳超过了2ppm的排放量,导致全国气温升高最新数据显示,全球大气中的二氧化碳浓度又创新高,增长速率比预期更高科学家担心,地球可能已经丧失了吸收二氧化碳的能力
我们美丽而又伟大的母亲病了—发烧
是因为我们每年排放的二氧化碳超过了2ppm的排放量,导致全国气温升高
最新数据显示,全球大气中的二氧化碳浓度又创新高,增长速率比预期更高科学家担心,地球可能已经丧失了吸收二氧化碳的能力:“我们正处在气候变化的关节点上,这不是什么好消息
为了保护地球我建议;
1把我们的空调调高到环保温度26度因为,26度是空调比较省电同学们你们知道电是怎么来的吗电是用煤烧出来的我们一年烧的煤所排放出的二氧化碳的数量可是一个惊人的数目所以大家少用电就是在减少二氧化碳的排放量了
2少买不必要的家用电器因为,生产电器的工厂也属于工业工厂我在前面也提过了,工业工厂是排放二氧化碳最多,所以,大家一定要少买不必要的电器哦!
3少用一次性电池,因为,生产电池的工厂也是工业工厂哦!而且一颗电池可以污染一个人一生所需要的水所以,不但要少用一次性电池而且用完了也不可以乱丢哦!
保护环境人人有责,这句话都是大家熟习的现在大家不但要把它记在心里还要行动起来哦!保护环境就是保护我们的地球母亲和给我们后代一个健康绿色的家园
