Comparing with the past, do you feel any warmer these days? Maybe you don’t take much notice of it. Nevertheless, on account of the burning of fossil fuels, the temperature has been increasing during the 20th century. In consequence, green house gasses（mostly CO2）trap heat from the sun and therefore warm the earth, causing both rising of sea level and terrible climate catastrophe. Presume that the temperature keeps on going up, no bright sunshine will visit us, unclear air will choke us and heat wes will kill us mercilessly.

However, much to our delight, nowadays countries and some organizations are aware of the importance of cutting the producing of carbon-dioxide. The U.N. Climate change conference opened in Copenhagen, Denmark on Dec.7th, 2009 arouses great concern from experts and officials, us included. Besides, in China, an effective law system has been set up to oid producing too much greenhouse gasses.

Well goes a saying that protecting the earth is protecting ourselves. At the same time we are supposed to undertake the responsibility to lead a low-carbon lifestyle, which is of great significance. Needless to say, low-carbon lifestyle means a lot to our society. First of all, so great a method is it to control the global warming that we are bound to make good use of it. Moreover, to some degree, it contributes a lot to our health.

Absolutely there is a diversity of measures we can take so as to lead such an environmental-friendly life. For one thing, it is known to us all that large quantities of greenhouse gases are produced mostly by motor vehicles so that we, if possible, can walk or ride to school instead of depending on cars all the time. For another, we should spare no efforts to reduce energy in our daily life, for energy in the world today is decreasing rapidly. For instance, we can turn off electrical liances if not necessary as well as using recycled materials. Furthermore, at our leisure, we can seek opportunities to plant more trees which can absorb carbon-dioxide. Last but not least, we are responsible for calling on others to lead low-carbon lifestyles.

In brief, low-carbon lifestyle is nothing but the best choice for us and only in this way can we form a harmonious relationship with the environment.

第二节 书面表达(满分25分)你校针对全球气候变暖对人类和生态环境产生的影响，进行了讨论。请你根据下表

there Are many reasons for global warming, summed up the future include the following:

1. Population explosion factor

In recent years, the rapid increase in population led to one of the main factors of global warming. At the same time, it is also a serious danger ribs with a balance between the natural ecological environment. So many people, only its own emissions of carbon dioxide per year would be a staggering figure, the result will lead directly to the content system of atmospheric carbon dioxide is increasing, so the formation of carbon dioxide "greenhouse effect" will directly affect the Earth's surface climate change.

2. Atmospheric pollution factors

At present, the worsening of environmental pollution has posed a major global problem, but also contribute to global warming, one of the main factors. Now, with regard to global climate change research has clearly pointed out that since the beginning of last century the Earth's surface temperature has already started to rise.

3. Of land erosion, desertification and other damage factors

4. Forest Resources sharp reduction factor

Around the world, due to natural or man-made factors are causing the forest area dropped significantly.

英语作文 THE CRISIS OF GLOBAL WARMING

1、Global warming is a natural phenomenon. Because people burning fossil fuel, such as oil, coal, or deforestation and the burning will produce large amounts of carbon dioxide, the greenhouse gas, these greenhouse gases on the radiation from the sun visible light has high permeability, and the long we radiation emitted from the earth with a highly absorbent, can strongly absorb infrared radiation on the ground, resulting in the earth's temperature to rise, the greenhouse effect. And when the greenhouse effect will continue to accumulate, resulting in gas absorption and emission of energy balance, energy accumulation in the earth atmosphere system, resulting in rising temperature, resulting in the phenomenon of global warming. Global warming will make the global distribution of precipitation, glaciers and permafrost melting, sea level rise, not only endanger the balance of natural ecosystems, but also threaten the survival of mankind.

2、全球气候变暖是一种自然现象。由于人们焚烧石燃料，如石油，煤炭等，或砍伐森林并将其焚烧时会产生大量的二氧化碳，即温室气体，这些温室气体对来自太阳辐射的可见光具有高度透过性，而对地球发射出来的长波辐射具有高度吸收性，能强烈吸收地面辐射中的红外线，导致地球温度上升，即温室效应。而当温室效应不断积累，导致地气系统吸收与发射的能量不平衡，能量不断在地气系统累积，从而导致温度上升，造成全球气候变暖这一现象。全球变暖会使全球降水量重新分配、冰川和冻土消融、海平面上升等，不仅危害自然生态系统的平衡，还威胁人类的生存。

怎么用英语写全球变暖的利与弊

Global warming has quickly bee one of the most heated issues. With the development of the economic, the emission of the green house gas, consisting of about 70% carbon dioxide, has been increased, attributing greatly to the global warming.

Global warming is the slow and steady increase in the temperature of earth and its atmosphere. The increase in the temperature of earth has caused many effects like the melting of ice in Polar Regions, increase in disease occurrences, drastic climatic changes and rise of the sea level.

As the effects of global warming is being more and more evident, many of us he started to realize that steps he to be taken to control Global warming, such as the usage of clean

energy resources and the alternative of motor.

这是全球变暖对农作物生长的利与弊 不知道可不可以？

1、气候变得更暖和，冰川消融，海平面将升高，引起海岸滩涂湿地、红树林和珊瑚礁等生态群丧失，海岸侵蚀 全球变暖的可怕后果

，海水入侵沿海地下淡水层，沿海土地盐渍化等，从而造成海岸、河口、海湾自然生态环境失衡，给海岸带生态环境带来了极大的灾难。 2、水域面积增大。水分蒸发也更多了,雨季延长,水灾正变得越来越频繁。遭受洪水泛滥的机会增大、遭受风暴影响的程度和严重性加大，水库大坝寿命缩短。 3、气温升高可能会使南极半岛和北冰洋的冰雪融化。北极熊和海象会渐渐灭绝。 4、许多小岛将会无影无踪； 5、因为还有热力惯性的作用，现有的温室气体还将继续影响我们的生活。 6、温度升高，会影响人的生育，精子的活性随温度升高而降低……. 7、.原有生态系统的改变。 8、对生产领域的，例如：农业，林业，牧业，渔业等部门…… 9、将感染疾病等传染病……病菌通过极端天气和气候（厄尔尼诺现象，干旱，洪涝，热浪等……） ，扩大疫情的流行，对人体健康危害……

对气候的影响

将更多的二氧化碳和温室气体排放到大气中所造成的危害，谁也无法确切地说明将来会有多严重？科学家正在估算气候变化所带来的危害。按目前的技术水平计算，2004年才能阐明大气中二氧化碳形成和消解的机理，这样就能发现温室效应是如何产生的。2006年才能准确的预知因地球升温而造成的海平面上升。然而真正理解这一切要到2050年。显然，科学家和政治家都不会等到进一步的结果出来才取防治措施，现在的观察和研究成果应该都让公众了解，才不至于使人们不得不在50年后自咽苦果。 温室效应自地球形成以来，它就一直在起作用。如果没有温室效应，地球表面就会寒冷无比，温度就会降到零下20℃，海洋就会结冰，生命就不会形成。因此，我们面临的不是有没有温室效应的问题，而是人类通过燃烧化石燃料把大量温室气体排入大气层，致使温室效应与地球气候发生急剧变化的问题。 温室效应会产生什么样的影响呢？由于矿物燃料的燃烧和大量森林的砍伐，致使地球大气中的二氧化碳浓度增加，由于二氧化碳等气体的温室效应，在过去100年里，全球地面平均温度大约已升高了0.3—0.6℃，到2030年估计将再升高1—3℃。 当全世界的平均温度升高1℃，巨大的变化就会产生：海平面会上升，山区冰川会后退，积雪区会缩小。由于全球气温升高，就会导致不均衡的降水，一些地区降水增加，而另一些地区降水减少。如西非的萨赫勒地区从1965年以后干旱化严重；我国华北地区从1965 年起，降水连年减少，与50年代相比，现在华北地区的降水已减少了1/3，水减少了1/2；我国每年因干旱受灾的面积约4亿亩，正常年份全国灌区每年缺水300亿立方米，城市缺水60亿立方米。 当全世界的平均温度升高3℃,人类也已经无力挽回了，全球将会粮食吃紧。 由于气温升高，在过去100年中全球海平面每年以1——2毫米的速度在上升，预计到2050年海平面将继续上升30—50厘米，这将淹没沿海大量低洼土地；此外，由于气候变化导致旱涝、低温等气候灾害加剧，造成了全世界每年约数百亿以上美元的经济损失。

冰川融化

近年来，人们对从巴塔哥尼亚到瑞士的阿尔卑斯山地区的冰川因为“温室”气体的排放和普遍认为的 南极冰川融化速度加快

温室效应而融化的情况进行了观察。在南亚地区，问题并不是冰川是否在融化，而是融化的速度有多快？虽然全球变暖的许多不良影响可能要到21世纪末才会变得非常严重，但是尼泊尔、印度、巴基斯坦、中国和不丹等地的冰川融水可能很快就会给人们造成麻烦。 国际冰雪委员会（ICSI）的一份研究报告指出：“喜玛拉雅地区冰川后退的速度比世界其它任何都要快。如果目前的融化速度继续下去，这些冰川在2035年之前消失的可能性非常之大”。国际冰雪委员会负责人塞义德·哈斯内恩说：“即使冰川融水在60至100年的时间里干涸，这一生态灾难的影响范围之广也将是令人震惊的。” 位于恒河流域的喜玛拉雅山东部地区冰川融化的情况最为严重，那些分布在“世界屋脊”上的从不丹到克什米尔地区的冰川退缩的速度最快。以长达3英里的巴尔纳克冰川为例，这座冰川是4000万——5000万年前印度次大陆与亚洲大陆发生碰撞而形成的许多冰川之一，自1990年以来，它已经后退了半英里。在经过了19年严寒的亚北极区冬季之后，科学家们曾经预计这条冰川会有所扩展，但是它在1998年夏天反而进一步后退了。

疾病肆虐

哈佛大学新病和复发病研究所的保罗．受泼斯坦注意到，植物也随雪线而移动，全世界山峰上的植物都在上移。随着山峦顶峰的变暖，海拔较高处的环境也越来越有利于蚊子和它们所携带的疟原虫子这样的微生物生存。 西尼罗、疟疾、黄热病等热带传染病自1987年以来在美国的佛罗里达、密西西比、德克萨斯、亚利桑那、加利福尼亚和科罗拉多等地相继爆发，一再证实了专家们关于气候变暖，一些热带疾病将向较冷的地区传播的科学推断。

新冰河期

关于全球变暖的另一项研究结果更令人吃惊，由北极冰原融化，降雨量增加，以及风的类型的不断改变，大量淡水正汇入北大西洋，对墨西哥湾暖流造成破坏，从而切断北大西洋暖流。正是这些暖流把温暖的表层水从加勒比海带到欧州西北部，并使欧洲形成温暖的气候。而北大西洋暖流一旦因全球变暖被切断后，欧洲西北部温度可能会下降5－8℃之多，欧洲可能面临一次新的冰河时代！ 这项研究是位于阿伯丁的苏格兰海洋实验所分析了设在兰群岛海域到法罗群岛海域之间自1893年以来的1.7万多次海水盐度测量结果得出的。在过去的每20年中，流向南部的深层海水盐度变得越来越小，浓度越来越低，这表明有更多的淡水从大西洋北部汇入了该地区。这些新数据第一次充分证明了德国科学家在大约3年前设计的计算机模型。 大气中的二氧化碳的含量急剧升高，而世界人口将在2050年之前达到100亿。“我们的世界正在朝着由人造设施来代替现有免费自然的方向发展”，明尼苏达大学的戴维·蒂尔曼说。但是，我们还没有掌握自然生态系统的有关知识。在2.45亿年前的二叠纪大灭绝中，96%的物种灭亡了。后来随着许多新物种的出现，地球上终于恢复了丰富的种群，但是这个过程足足经历了一亿年。威尔逊说：“一些人认为，自然界会复兴人类所毁灭的一切” 。谚语云：“只要有足够的时间，万物皆可应运而生。”或许自然界真的能够恢复一切，但这个漫长的过程对于现代人类无论如何是没有意义的。 马克·吐温曾经说过，天气最动人的特质就在于它的变化多端。1个多世纪过去了，我们仍然在为准确预报天气情况而努力，在控制气候方面却收效甚微；然而，对环境的破坏却是史无前例的。

生态

首先，全球气候变暖导致海平面上升，降水重新分布，改变了当前的世界气候格局；其次，全球气候变暖影响和破坏了生物链、食物链，带来更为严重的自然恶果。例如，有一种候鸟，每年从澳大利亚飞到我国东北过夏天，但由于全球气候变暖使我国东北气温升高，夏天延长，这种鸟离开东北的时间相应变迟，再次回到东北的时间也相应延后。结果导致这种候鸟所吃的一种害虫泛滥成灾，毁坏了大片森林。另外，有关环境的极端增加，比如干旱、洪水等。

政治

限制二氧化碳的排放量就等于是限制了对能源的消耗，必将对世界各国产生制约性的影响。应在发展中国家“减排”，还是在发达国家“减排”成为各国讨论的焦点问题。发展中国家的温室气体排放量不断增加，2013年后的“减排”问题必然会集中在发展中国家。有关阻止全球气候变暖的科学问题必然引发“南北关系”问题，从而使气候问题成为一个国际性政治问题。

气候

全球气候变暖使大陆地区，尤其是中高纬度地区降水增加，非洲等一些地区降水减少。有些地区极端天气气候（厄尔尼诺、干旱、洪涝、雷暴、冰雹、风暴、高温天气和沙尘暴等）出现的频率与强度增加。

海洋

随着全球气温的上升，海洋中蒸发的水蒸气量大幅度提高，加剧了变暖现象。而海洋总体热容量的减小又可抑制全球气候变暖。另外，由于海洋向大气层中释放了过量的二氧化碳，因而真正的罪魁祸首是海洋中的浮游生物群落。

农作物

全球气候变暖对农作物生长的影响有利有弊。其一，全球气温变化直接影响全球的水循环，使某些地区出现旱灾或洪灾，导致农作物减产，且温度过高也不利于生长。其二，降水量增加尤其在干旱地区会积极促进农作物生长。全球气候变暖伴随的二氧化碳含量升高也会促进农作物的光合作用，从而提高产量。

人体健康

（1）全球气候变暖直接导致部分地区夏天出现超高温，心脏病及引发的各种呼吸系统疾病，每年都会夺去很多人的生命，其中又以新生儿和老人的危险性最大。 （2）全球气候变暖导致臭氧浓度增加，低空中的臭氧是非常危险的污染物，会破坏人的肺部组织，引发哮喘或其他肺病。 （3）全球气候变暖还会造成某些传染性疾病传播。

The impact of climate 2 will be more carbon dioxide and greenhouse gas emissions to the harm caused by air, who are unable to accurately notes will be more serious? Scientists are estimated as a result of climate change. The current level of technology, 2, 2004, atmospheric carbon dioxide to clarify and resolve the mechanism, so as to find ways to produce the greenhouse effect. The Year 2006 can be accurately predict the result of global warming and sea level rise. However really understand this to the year 2050. It is clear that scientists and politicians will not wait until further results e out to take measures to bat the observation and research results to the public should understand that they will not make it had to swallow the bitter fruit after 50 years. Since the earth has been a greenhouse effect, it has been in effect. If there is no greenhouse effect, the earth surface will be extremely cold temperature will drop to minus 20 degrees C, will the sea ice, life will be formed. Therefore, we face is not whether the greenhouse effect, but human through the burning of fossil fuels Significant greenhouse gas emissions into the atmosphere, the greenhouse effect and the Earth climate changed dramatically. What kind of impact will greenhouse effect? the bustion of fossil fuels and massive deforestation, as a result of the global atmospheric carbon dioxide concentration 2, 2 the carbon dioxide emissions of greenhouse gases, such as in the past 100 years, the global erage surface temperature has risen by around 0.3-0.6 degrees C, estimated to rise to 2030-1 3 0 c.

When the world erage temperatures 1 o C, great changes in the will of sea level rise, the mountain glaciers will retreat, snow areas will be reduced. As global warming will lead to uneven rainfall in some areas increased rainfall, while some regions precipitation. In the West African Sahel region in 1965 after years of drought of north China, in 1965, the rainfall years, pared with 50 years, the North China' s rainfall has decreased by 1/3, the water resources has been reduced by 1/2; every year due to drought affected an area of about 400 million mu, normal national water irrigation area every year, 30 billion cubic meters of water shortages in cities 6 billion cubic meters. When the world erage temperatures 3 o C, mankind has been unable to restore the global food will be critical. The temperature rise in the past 100 years in the global sea level on an annual rate of 1-2 mm on the rise in sea level is expected to 2050 will continue to rise 30-50 centimeters, and this will be inundated large low-lying coastal land; in addition, droughts and floods caused by climate change, low temperature, increasing climate disasters, resulting in the world each year roximately US dollars more than 10 billion in economic losses.

In recent years, the people of Trinidad and Tobago, the Swiss Alps region because of the "ice" greenhouse gas emissions and generally believed that the accelerated melting of glaciers in Antarctica
