气候变化的原因英语作文

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.

气候变化英语作文120词

With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike.
So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.

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。

one of the most serious problem in front of the world is the global warming.there are some reasons that can cause such a problem.first,people cut down trees and forests freely.besides,people burn things everywhere - even it is not allowed.people waste things out of control is another reason.so,we should try our best to save things as much as we can.we should encourage others to do so.if we do it,the stage will be better.if we don't take any action,as the warld is becoming warmer and warmer,the water level is rising.it can cause subsidence and threaten people's activities.
