气候变化的影响和危害论文范文英语
范文毕竟是别人的,要学会利用其中的好句子,句型,不要照抄,底下是我找的一些,你来晚了一小步,我刚考完中考,电脑里储存的英语学习资料都詧除掉了,中考其实作文并不太难(安徽的),单词一定要背完背熟。还有能不呢不过提个意见,“15分呐”说那么夸张,口气像是150分:-)英语中考作文焦点——以环保话题 今年几个世界大国首脑都参加了“八国峰会”,这次的主题是世界经济、能源问题和气候变化。经济发展离不开环境话题,能源使用必然污染环境,而气候变化就是经济发展和环境问题矛盾的产物。广西的城乡清洁工程表面就是环境整治问题。学校的两基工作从某种意义上来说其实就是学校环境改变没有。2008年北京奥运会也离不开环保这个主题。八荣八耻也有部分内容是关于环保主题的。总之,环境保护是当今世界难题。因此,中考的内容离不开以下这些范文要点,而且都是记叙文形式,有些句子相当有用,不论什么作文,都可以从下列文章选出相应句子,只需稍微改一下地名或主语,尽量减少语法错误,起码有4、5分是正确的。如:Throw the waste here and there(到处乱扔垃圾)变成Don~t throw the waste here and (不准乱扔垃圾)。“应该”变成“不应该”等等。我想中考作文完全可以取得高分。比如:作文题:1、职业:将来想干什?或者你的爱好是什么?(或者题目是:毕业之后)你可以写将来做一个环保注意者,如何做?做什么。2、如果题目是写我的班级、学校、家乡之类的更加可以谈到环保情况(讲现象,有好有坏,如何去改变?有什么措施?如何的美?)3、如果是写为什么北京有沙尘暴、为什么今年有些省份干旱少雨?为什么有些省份洪涝灾害严重。那就是环境破坏问题。因此关键最后几天最好能背熟这些范文。 尽量围绕环保展开主题,通过过渡句和环保扯上联系。比如:(过渡句)The most important question in the world today is pollution (当今世界最重要的话题就是污染问题。) 范文提示 1) It’s our duty to save water(节约水是我们每个人的责任。) As we know , water is very important to man, (我们知道,水对人类来说是非常的重要。)we can’t live without (没有水我们就不能生存。)The amount of water which is suitable to drink is less and (适合人类喝的水是越来越少了。)But some people don’t care about it (但是有些人却不关心或不在意。)They waste a lot of water in their daily (日常生活中他们浪费很多水。)Even worse, they pour dirty water in to (更糟糕的是他们排放污水到河流里。) They throw rubbish into rivers , (他们还乱扔垃圾到河流理去。)Many rivers and lakes are seriously (很多河流湖泊已经受到严重污染。) Something must be done to stop the (人类必须采取一些措施来制止污染。)Only in this way can we live (只有这样,我们才过得幸福开心。) If we don’t save water, the last drop of water will be a tear-drop of ( 如果我们不节约水,那么最后一滴水也许会是我们人类的眼泪) 2) Planting trees Trees are very helpful and important for (树对我们人类是多么的重要和有用。)We should plant more and more trees in order to live better and more healthy in the (为了将来我们的生活过得更好、更加健康我们应该种更多的树。)It’s everyone’s duty to love and protect the (爱护和保护环境是每个人的责任和义务。) 3) 旅游介绍 预览摘要: 北京奥运会期间,有一大批外国人来北京参观。假设你是导游,请根据以下内容,向外宾简单介绍北京的情况。 要求: 100 词左右; 要点包括: 有悠久的历史 有许多名胜古迹 Ladies and gentlemen,(女士们、先生们) Welcome to BeiJing, now let me introduce Beijng to (欢迎到北京,我来介绍北京给大家。) Beijing is a city with a long It is in the north of C It has a population of 13,240,(北京是一个历史悠久的城市,它位于中国的北部,人口000) There are many places of interest in Beijing, such as the Summer Palace and so (北京有很多名胜古迹,象颐和园等等。) The Great Wall is a beautiful ( 长城是个漂亮的地方。)There is a saying that he who has never been to the Great Wall is not a true (有句谚语说:不到长城非好汉)The water in Miyun Reservoir is clean and not (密云水库的水很干净没有受污染。)There are all kinds of fish in (里边有各种各样的鱼。)You can go boating, go fishing and have a picnic (那里你可以划船、钓鱼或者野炊。) It is really a good place to spend your (那里真是个度假的好地方。)Besides, you can go and visit Beijing M (此外,你还可以去游览北京博物馆。)There you can see a lot of dinosaur egg (那里你可以看到很多恐龙蛋和化石。) I hope you can enjoy yourselves in B(我希望大家在北京玩得开心快乐。) Thank (谢谢) 4)、近日,你班在“知荣明耻” “八荣八耻大家谈”教育活动中,召开了一次关于学生荣辱观的主题班会。存在的问题1.不尊敬老师、家长等。2.学习散漫、考试作弊等。3.乱扔垃圾、污损环境等等。 Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is (最近我们班开了个班会讨论什么是光荣和耻辱。)It is really a pity to see all this in our (很遗憾在学校看到这些现象)Some students don’t respect their teachers or (不尊敬老是和父母)Some don’t take their studies seriously and cheat in (作业不认真,考试作弊)Some throw wastes everywhere and pollute the environment (到处乱扔垃圾污染环境。)It is honorable to obey the law and rules , care much about our class and study (关心班级、努力学习、遵纪守法是光荣)It is shameful to break school rules, to be selfish or to make little effort to achieve (违反学校纪律、自私 骄傲是可耻的)We should respect others and think more of them than of (我们应该尊敬别人经常关心别人)We should work hard and make much more progress to repay the (我们应该努力学习取得更大进步从而回报社会。)We should try our best to keep the environment clean。(我们应该想方设法保持干净的环境。) 人与环境是和谐相处的,我们生存在地球上,人是自然之子,而不能仅把人看作自然的征服者,大家都知道,人类只有一个地球,地球上的山山水水、动物。植物是人类的细胞,如果我们把它损坏了,破坏了大自然的组织,等 于消灭人类。因此,环境要与社会公德联系起来,与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。 Harmony with the environment is that

气候变暖会使北极和南极的冰川融化,冰融化后就会变成水,地球被水占据%70,再加上冰融化的水,会使水无区域流动,然后涌向城市,城市就成了水的家了,地球到时候有%197的水了,最后地球将变成一个没有生命的星球。Edfjiehrugjfdlairglpejvnclksmviriufjghk,uhgrncb%70,duvnfghndfbvxdfnv,fdcbhvfhjdhjbcsmvhf,jdushfjhdavjhf,chengshijiuchengleshuidejiale,zuihoudiqiuhuibianchengshuiqiu,xiaoshizaiyuzhou dshfuweihqjkwdhcjsn,
哥本哈根气候大会将于12月7日到18日召开,目前,全球相关专家都在“摩拳擦掌”,一些国家也纷纷在会前表姿态,避免做减排“罪人”。可是,许多人不明白,为什么要关注看似杞人忧天的“100年后全球气温上升2℃”?科学家在对数千份科学文件进行精心研究后,系统描述了地球气温升高后全球面临的灾难。 气温上升1℃美国粮仓变大漠非洲沙漠成桑田 美国南部地区是美国的大粮仓,尤其是沙山地区出产美国最好的牛肉。但这片广阔的土地全是沙质结构。换言之,在6000多年前,美国的气温比现在高1℃的时候,这片肥美的草原当时是寸草不生的大漠。因此,如果全球气温再上升1℃的话,美国的“粮仓”将重新变回大漠,从而将人类逼出这一地区。 今天全球最热的撒哈拉大漠可能会变得湿润起来,重现6000年前岩画中大象、水牛和野羊在肥美草原上巡游的美丽景象。而11000年来,乞力马扎罗山峰一直戴着的雪白冰帽将不复存在,使得整个非洲大陆成为真正的无冰世界。欧洲的阿尔卑斯山的冰雪也将全部融化。 受全球气温升高1℃影响最大的还有热带的珊瑚。其中澳大利亚大堡礁的珊瑚将会全部死亡。这主要是因为二氧化碳的排量增加,增加的二氧化碳融入海水,使得海水的酸性大增。 气温上升2℃海水上升7米1/3动植物消亡 假如气温上升2℃,地球又会怎样呢?亲历过2003年欧洲夏天热浪的人或许知道,这将是莫大的灾难。在2003年的那场热浪中,至少有 30000人死于酷热。 气温上升2℃,意味着格陵兰岛的冰盖将彻底融化,从而使得全球海洋的水平面上升7米。科学家做出这一推测的依据是,大约125000年前,地球的气温比现在平均高出1℃至2℃,结果全球的冰盖全部融化。因此,当气温上升2℃时,全球的山脉都会受影响,比如为利马河提供水源的安第斯山系的冰架将全部消失。 全球的食物,尤其是热带地区的食物将大受影响。三分之一的动植物种群因为天气变化而灭绝。科学家估计,如果我们还想将全球气温上升控制在2℃ 以内,那么从现在起还有10年时间让人类控制二氧化碳排放量。 气温上升2℃,疟疾患者也会增加,疟疾是与结核病、艾滋病并列的三大传染病之一。疟疾是由疟原虫引起的寄生虫病,热带生存的按蚊是疟原虫的主要传播体。地球平均气温上升,蚊虫生存的季节和地区也将发生变化,因此,以前未发生过疟疾的地区,也会因有按蚊传播而产生疟疾的危险。 气温上升3℃气候彻底失控上演生态灾难 气温上升3℃是地球的一个重大“拐点”,因为地球气温一旦比现在上升3℃,就意味着全球变暖的趋势将彻底失控,人类再也无力介入地球气温的变化。 气温上升3℃的灾难核心区将是南美洲的亚马逊热带雨林。由于气温上升,今天仍占地100万平方公里的热带雨林将频频遭遇火灾。根据计算机模拟结果,干旱使得亚马逊热带雨林无力防火,一个小小的雷击都有可能引发热带雨林大火,最终甚至烧毁整个热带雨林。一旦树林消失,亚马逊雨林上取而代之的将是荒漠。 气温上升3℃将使南部非洲和美国西部开始出现更大面积的沙漠,使得成百上千万原来从事农牧业的人被迫背井离乡。 在欧洲大陆和英国,夏季干旱高温与冬天极冷相伴而来,一些低海拔的沿海地区被海水淹没。 海洋大循环也将会停止,在数千米到1万米的深海处流动着的海流,大约2000年来一直在绕地球一周,被称为海洋大循环,它起着稳定地球气候的重要作用。但是,如果地球平均气温上升,引起海水温度上升,以及格陵兰岛冰雪融化,海水中盐分的浓度减少,本来该沉入深海的海水沉不下去,从而有可能导致海洋大循环停止。有关专家说,一旦海洋大循环停止,地球气候就会变得很不稳定,某些地区也有可能突然变得很寒冷。 气温上升4℃人类口粮吃紧欧洲人大迁徙 气温上升4℃对于地球的大部分地区来说都是灾难。这意味着数10亿吨被冰封在南北两极和西伯利亚的二氧化碳气体将释放出来,进入臭氧层,从而成为全球变暖的倍增器。此时,北冰洋所有的冰盖将全部消失,北极成了一片浩瀚的海洋,这是地球300万年来首度发生这样的现象,北极熊和其他需要依赖冰为生的动物将彻底灭绝。南极的冰盖也将受到很大影响,南极洲西部地区的冰盖将与大陆脱离,最终海平面上涨,从而使全球的沿海地区再度被海水吞没。在欧洲,新的沙漠开始形成,并且向意大利、西班牙、希腊和土耳其扩展。在如今温度宜人的瑞士,夏季的气温将高达48℃,比现在的巴格达还热。阿尔卑斯山最高峰将彻底没有冰雪,裸露出巨大的岩石。由于气温持续保持在45℃,欧洲人被迫向北迁居。 在全球平均气温上升4℃的情况下,北极地区气温可能达到16℃,地中海沿岸地区水资源将减少70%,美洲的玉米和谷物产量将减少40%,而亚洲一些国家的水稻产量将减少30%。 4℃的升温幅度并不会在全球平均分布,陆地比海洋的升温要快,高纬度地区尤其是北冰洋地区的升温幅度也会更大。气候变化也将对人类活动产生部分影响,尤其是对供水、农业生产、极端气温和干旱、森林山火和海平面上升等方面的严重影响。 气温上升5℃至6℃地球将面临彻底的灾难科学家们在加拿大北极圈内发现了鳄鱼和乌龟的化石。这说明5500万年前,这些动物曾经在加拿大北极圈内生活过。因此,一旦全球气温上升5℃至6℃,绿色阔叶林将重现加拿大北极圈,而南极的腹地也会有类似的情景。然而,由于陆地大部分被淹没,动植物无法适应新的环境,因此将有 95%的种类灭绝,地球面临着一场与史前大灭绝一样的劫难。 甲烷水合物将崩解,甲烷水合物是甲烷气体与水的化合物,也被称为可燃冰。现在,大部分可燃冰深藏于海底、南极大陆冰层和永久冻土层内。地球平均气温上升5℃,冰和冻土融化,甲烷水合物就有可能崩解。科学家担心,如果这种情况发生,大量会导致温室效应的甲烷气体就会释放到空气中,有可能进一步加剧地球气候变暖。(据人民网) 气温升高导致北极冰雪融化,北极冰架持续消失,这导致北极熊的生存空间大大减少。
全球变暖会引起温度带的北移,进而导致大气运动发生相应的变化,全球降水也将随之发生变化。一般地,低纬度地区现有雨带的降水量会增加,高纬度地区冬季降雪量也会增多,而中纬度地区夏季降水量将会减少。对于大多数干旱、半干旱地区,降水量增多是有利的。而对于降水减少的地区,如北美洲中部、中国西北内陆地区,则会因为夏季雨量的减少变得更加干旱,水源更加紧张。 据估算,在综合考虑海水热胀、由于极地降水增加导致南极冰帽增大、北极和高山冰雪融化等因素的前提下,当全球气温升高5~5°C时,海平面将可能上升20~165厘米。海平面的上升无疑会改变海岸线,给沿海地区带来巨大影响,目前海拔较低的沿海地区将面临被淹没的危险。海平面上升还会导致海水倒灌、排洪不畅、土地盐渍化等其他后果。 尽管存在着许多的不确定性,但显而易见的是,全球气候变暖对气候带、降水量以及海平面的影响以及由此导致的对人类居住地及生态系统的影响是极其复杂的,必须给予应有的重视。认为这种影响从长远来看是无关紧要的看法是不负责任的Global warming will cause temperatures with the north, which led to corresponding changes in atmospheric motion, the global precipitation will subsequently In general, the low-latitude regions, the existing precipitation will increase with the rain, snowfall in winter at high latitudes will increase, while the mid-latitudes in summer precipitation will be For most of the arid and semi-arid regions, increased precipitation is As for the reduction in precipitation, such as central North America, northwest China inland, the summer rainfall will decrease because of increased drought and water even more It is estimated considering the water in the thermal expansion, due to increased precipitation led to the Antarctic Polar

Global warming has posed a serioud threat to the survival of humanity in the Few people have realized that what our actions in this time mean more ato our future than 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 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 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 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 Among all the green energy sources, residential solar power generation has the potency to save the 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 China has the most potential in achieving a Solar Revolution, because China has the most potential in the suply and demand of solar Suntect Power ( 尚德) , a remarkable Chinese solar company, offers high quality products in world standard in really low Chinese prices, a miraculous On the demand, a greatest number of residential owners in the world could possible want to get solar generated 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 C As the situation entails,everyone of us has responsiblities to protect the planet and ensure the survival of our 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 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 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 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。
气候变暖会使北极和南极的冰川融化,冰融化后就会变成水,地球被水占据%70,再加上冰融化的水,会使水无区域流动,然后涌向城市,城市就成了水的家了,地球到时候有%197的水了,最后地球将变成一个没有生命的星球。Edfjiehrugjfdlairglpejvnclksmviriufjghk,uhgrncb%70,duvnfghndfbvxdfnv,fdcbhvfhjdhjbcsmvhf,jdushfjhdavjhf,chengshijiuchengleshuidejiale,zuihoudiqiuhuibianchengshuiqiu,xiaoshizaiyuzhou dshfuweihqjkwdhcjsn,
哥本哈根气候大会将于12月7日到18日召开,目前,全球相关专家都在“摩拳擦掌”,一些国家也纷纷在会前表姿态,避免做减排“罪人”。可是,许多人不明白,为什么要关注看似杞人忧天的“100年后全球气温上升2℃”?科学家在对数千份科学文件进行精心研究后,系统描述了地球气温升高后全球面临的灾难。 气温上升1℃美国粮仓变大漠非洲沙漠成桑田 美国南部地区是美国的大粮仓,尤其是沙山地区出产美国最好的牛肉。但这片广阔的土地全是沙质结构。换言之,在6000多年前,美国的气温比现在高1℃的时候,这片肥美的草原当时是寸草不生的大漠。因此,如果全球气温再上升1℃的话,美国的“粮仓”将重新变回大漠,从而将人类逼出这一地区。 今天全球最热的撒哈拉大漠可能会变得湿润起来,重现6000年前岩画中大象、水牛和野羊在肥美草原上巡游的美丽景象。而11000年来,乞力马扎罗山峰一直戴着的雪白冰帽将不复存在,使得整个非洲大陆成为真正的无冰世界。欧洲的阿尔卑斯山的冰雪也将全部融化。 受全球气温升高1℃影响最大的还有热带的珊瑚。其中澳大利亚大堡礁的珊瑚将会全部死亡。这主要是因为二氧化碳的排量增加,增加的二氧化碳融入海水,使得海水的酸性大增。 气温上升2℃海水上升7米1/3动植物消亡 假如气温上升2℃,地球又会怎样呢?亲历过2003年欧洲夏天热浪的人或许知道,这将是莫大的灾难。在2003年的那场热浪中,至少有 30000人死于酷热。 气温上升2℃,意味着格陵兰岛的冰盖将彻底融化,从而使得全球海洋的水平面上升7米。科学家做出这一推测的依据是,大约125000年前,地球的气温比现在平均高出1℃至2℃,结果全球的冰盖全部融化。因此,当气温上升2℃时,全球的山脉都会受影响,比如为利马河提供水源的安第斯山系的冰架将全部消失。 全球的食物,尤其是热带地区的食物将大受影响。三分之一的动植物种群因为天气变化而灭绝。科学家估计,如果我们还想将全球气温上升控制在2℃ 以内,那么从现在起还有10年时间让人类控制二氧化碳排放量。 气温上升2℃,疟疾患者也会增加,疟疾是与结核病、艾滋病并列的三大传染病之一。疟疾是由疟原虫引起的寄生虫病,热带生存的按蚊是疟原虫的主要传播体。地球平均气温上升,蚊虫生存的季节和地区也将发生变化,因此,以前未发生过疟疾的地区,也会因有按蚊传播而产生疟疾的危险。 气温上升3℃气候彻底失控上演生态灾难 气温上升3℃是地球的一个重大“拐点”,因为地球气温一旦比现在上升3℃,就意味着全球变暖的趋势将彻底失控,人类再也无力介入地球气温的变化。 气温上升3℃的灾难核心区将是南美洲的亚马逊热带雨林。由于气温上升,今天仍占地100万平方公里的热带雨林将频频遭遇火灾。根据计算机模拟结果,干旱使得亚马逊热带雨林无力防火,一个小小的雷击都有可能引发热带雨林大火,最终甚至烧毁整个热带雨林。一旦树林消失,亚马逊雨林上取而代之的将是荒漠。 气温上升3℃将使南部非洲和美国西部开始出现更大面积的沙漠,使得成百上千万原来从事农牧业的人被迫背井离乡。 在欧洲大陆和英国,夏季干旱高温与冬天极冷相伴而来,一些低海拔的沿海地区被海水淹没。 海洋大循环也将会停止,在数千米到1万米的深海处流动着的海流,大约2000年来一直在绕地球一周,被称为海洋大循环,它起着稳定地球气候的重要作用。但是,如果地球平均气温上升,引起海水温度上升,以及格陵兰岛冰雪融化,海水中盐分的浓度减少,本来该沉入深海的海水沉不下去,从而有可能导致海洋大循环停止。有关专家说,一旦海洋大循环停止,地球气候就会变得很不稳定,某些地区也有可能突然变得很寒冷。 气温上升4℃人类口粮吃紧欧洲人大迁徙 气温上升4℃对于地球的大部分地区来说都是灾难。这意味着数10亿吨被冰封在南北两极和西伯利亚的二氧化碳气体将释放出来,进入臭氧层,从而成为全球变暖的倍增器。此时,北冰洋所有的冰盖将全部消失,北极成了一片浩瀚的海洋,这是地球300万年来首度发生这样的现象,北极熊和其他需要依赖冰为生的动物将彻底灭绝。南极的冰盖也将受到很大影响,南极洲西部地区的冰盖将与大陆脱离,最终海平面上涨,从而使全球的沿海地区再度被海水吞没。在欧洲,新的沙漠开始形成,并且向意大利、西班牙、希腊和土耳其扩展。在如今温度宜人的瑞士,夏季的气温将高达48℃,比现在的巴格达还热。阿尔卑斯山最高峰将彻底没有冰雪,裸露出巨大的岩石。由于气温持续保持在45℃,欧洲人被迫向北迁居。 在全球平均气温上升4℃的情况下,北极地区气温可能达到16℃,地中海沿岸地区水资源将减少70%,美洲的玉米和谷物产量将减少40%,而亚洲一些国家的水稻产量将减少30%。 4℃的升温幅度并不会在全球平均分布,陆地比海洋的升温要快,高纬度地区尤其是北冰洋地区的升温幅度也会更大。气候变化也将对人类活动产生部分影响,尤其是对供水、农业生产、极端气温和干旱、森林山火和海平面上升等方面的严重影响。 气温上升5℃至6℃地球将面临彻底的灾难科学家们在加拿大北极圈内发现了鳄鱼和乌龟的化石。这说明5500万年前,这些动物曾经在加拿大北极圈内生活过。因此,一旦全球气温上升5℃至6℃,绿色阔叶林将重现加拿大北极圈,而南极的腹地也会有类似的情景。然而,由于陆地大部分被淹没,动植物无法适应新的环境,因此将有 95%的种类灭绝,地球面临着一场与史前大灭绝一样的劫难。 甲烷水合物将崩解,甲烷水合物是甲烷气体与水的化合物,也被称为可燃冰。现在,大部分可燃冰深藏于海底、南极大陆冰层和永久冻土层内。地球平均气温上升5℃,冰和冻土融化,甲烷水合物就有可能崩解。科学家担心,如果这种情况发生,大量会导致温室效应的甲烷气体就会释放到空气中,有可能进一步加剧地球气候变暖。(据人民网) 气温升高导致北极冰雪融化,北极冰架持续消失,这导致北极熊的生存空间大大减少。

全球气候变暖的后果有:一、Climate(气候)Due to the burning of fossil fuels and deforestation, the concentration of carbon dioxide and other gases in the earth's atmosphere has Due to the greenhouse effect of these gases, the global average surface temperature has risen by about 3-6 C in the past 100 years, and it is estimated that it will rise by another 1-3 C in 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等气体浓度增加,由于这些气体的温室效应,在过去100年里,全球地面平均温度大约已升高了3~6℃,到2030年估计将再升高1~3℃。二、glacier(冰川)The Himalayan glaciers are retreating faster than anything else in the If the current rate of melting continues, the likelihood of these glaciers disappearing by 2035 is very Even if the meltwater dries up in 60 to 100 years, the impact of this ecological disaster will be 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。三、 ecology(生态)Firstly, global warming has caused sea level rise and redistribution of precipitation, which has changed the current world climate Secondly, global warming has impacted and destroyed the biological and food chains, bringing more serious natural 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。四、Politics(政治)Limiting carbon dioxide emissions is tantamount to limiting energy consumption and will have a restrictive impact on all countries of the Whether to reduce emissions in developing countries or in developed countries has become the focus of 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。五、Sea(海洋)With the rise of global temperature, the amount of water vapor evaporated in the ocean has increased dramatically, which aggravates the warming The decrease of the total heat capacity of the ocean can also inhibit global In addition, because the ocean releases excessive carbon dioxide into the atmosphere, the real culprit is the plankton community in the 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。

气候变化的影响和危害论文范文大全
温室气体而造成的,各种全球变暖背景下的极端气候影响在世界各地频频上演,暴雪、飓风、洪水、干旱……全球气候变暖还引起冰川崩塌消融、海平面上升、粮食减产、物种灭绝……在不可逆转的全球变暖大灾难到来之前,我们唯有节能减排,放弃化石燃料,改用可再生能源、节约能源、提高能效,减排温室气体,同时保护森林,多管齐下,才能有效遏制全球气候变暖趋势。 气候变化的影响范围极广,其中涉及了国防、人体健康、国际金融等领域。 据科学家预测:到2050年,亚洲大部分地区包括中亚、南亚和东亚、东南亚,淡水供应趋于紧张,这种紧张状况在一些大河流域会特别明显;在沿海地区特别是南亚、东亚和东南亚人口密集地区,洪涝风险将显著增加;在全球气候变化大背景下,伴随工业化、城市化和经济快速发展,亚洲地区自然资源和环境压力将进一步增加。此外气候变化对人体健康的影响,有可能表现为由洪涝、干旱引发的腹泻,其发病率和死亡率将明显增加。 就中国而言,气候变暖是导致异常气象灾害频发的主要原因。例如上海:位于长江的入海口,平均海拔仅4米,因此很容易受到海潮的侵袭。按货物吨位计算,上海属于世界上最繁忙的港口。2006年,海平面上升、暴风雨和咸水入侵,曾导致上海附近的农田、房屋和湿地受到破坏。WWF报告预测,到2050年海平面将上升30--50厘米,将导致上海地区大约4万平方公里(超过该地区一半面积)被淹。香港、新加坡、吉隆坡、曼谷和胡志明市,这些城市在全球气候变化中同样面临很大风险。 全球气候变化严重影响我国粮食安全。中国是个农业大国,农业生产受自然条件影响很大。到21世纪后半期,小麦、水稻、玉米几种主要农作物的产量将可能下降37%%,如果不采取任何措施,气候变化将严重影响我国长期的粮食安全。
可以从六个角度诠释: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暖,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,有关环境的极端事件增加,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事件(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种子生长。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。希望被采纳哦
主要介绍全球气候变暖及其影响、原因;应对全球气候变暖的措施
