温室效应与冰川融化的英文作文

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.

There are many harmful effects. It cause the sea level to rise and many natural disasters to strike. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes. People suffer a lot from disasters relevant to global warming.

Glaciers melting in the greenhouse effect is the result, along with the human industrialization expands gradually, every year in the amount of carbon dioxide emitted into the atmosphere, causing the global average temperature is abnormal, often rise, melting glaciers speed also rose sharply. 2010 is one of the two years meteorological record hot, global warming continues. The study found, the Greenland glacier area reduced 8%, how terrorist data!

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.

气候变化论文

摘要:近年来,全球气候变化已成为人类面临的最大威胁。化石燃料的大量燃烧,的无节制排 温室气体放,森林的过度砍伐,使全球气温急剧上升,导致了许多灾难性的后果,冰川退 缩,海平面上升……形势相当严峻。多种研究结果证实,过去50年观测到的全球平均温度 的升高是人为温室气体浓度增加引起的。必须将大气中二氧化碳浓度控制在一定的水平内,才能避免发生极端气候变化后果。低碳经济正是在应对气候变化背景下产生的新概念,并被视作解决气候问题的根本出路。低碳经济是以低能耗、低污染、低排放为基础的经济形态,其实质是通过能源技术和制度创新,提高能源利用效率,构造清洁能源结构,改变以化石燃料为主的现有能源消费格局。在2009年年底的哥本哈根会议上,低碳经济是“后危机时代” 的实体经济的方向与出路。气候变化危机归根到底是人类过度耗费自然资源而导致的危机,因此,要从根本上解决气候变化危机,就必须从改变人们生活态度和生活方式入手。这需要我们每一个人从身边做起,从一点一滴做起。 关键词:气候,气候变化,低碳,低碳经济 正文: 1. 气候变化( Climate change ) 气候变化是指气候平均状态统计学意义上的巨大改变或者持续较长一段时间(典型的 为10 年或更长)的气候变动。 1.1 气候变化简介 《联合国气候变化框架公约》 (UNFCC)C 第一款中,将“气候变化”定义为:“经过相当一段时间的观察,在自然气候变化之外由人类活动直接或间接地改变全球大气组成所导致的气候改变。” UNFCCC因此将因人类活动而改变大气组成的“气候变化”与归因于自然原因的“气候变率”区分开来。气候变化 ( climate change )主要表现为三方面:全球气候变暖( Global Warming )、酸雨( Acid Deposition )、臭氧层破坏( Ozone Depletion ),其中全球气候变暖是人类目前最迫切的问题,关乎到人类的未来! 1.2 气候变化的原因 气候变化的原因可能是自然的内部进程,或是外部强迫,或者是人为地持续对大气组成 成分和土地利用的改变。既有自然因素,也有人为因素。在人为因素中,主要是由于工业革命以来人类活动特别是发达国家工业化过程的经济活动引起的。化石燃料燃烧和毁林、土地利

全球变暖英语作文范文

全球变暖英语作文范文 在这一则报导中,我学到很多事,但我第一个想到的是,造成地球变暖的原因是二氧化碳增加。 In this paper, I have learned a lot of things, but I think the first one is the cause of global warming, the increase of carbon dioxide. 为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决,说不定可以改善地球继续暖化,例如:目的地很近的话可以骑自行车;目的地很远的话,可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。 Why carbon dioxide will increase? I think the reason is often drive, raising livestock, food factory emissions of smoke...... Etc.. But these are all can solve them together, it can improve the Earth continues to warm, for example: the destination is close enough to ride a bike; destination long enough, can take the public transport; waste livestock treated and then discharged into the Hanoi factory; to build a waste treatment plant...... Etc.. 请大家不要小看二氧化碳的威力,等到海平面上升、都市浸水和农地淹没,到最后就会面临粮食不足的危机了。请大家跟我一起喊:“停止伤害地球的行为吧!我们居住的地球只有一个。” Please do not underestimate the power of carbon dioxide, when the sea level rise, urban water and farmland submerged, eventually facing food shortage. Please call with me: "stop the harm to the earth's behavior! Only one earth on which we live. "

生态环境概论英语论文

People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced no-snow winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days. The side effects of global warming are alarming. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming. However global warming is mainly due to human activities, such as greenhouse gases generated by industrial production of nitrogen oxides and carbon dioxide. If the atmosphere in the absence of such gases, the Earth will become too cold and not suitable for biological survival. In the atmosphere of greenhouse gases have a certain thing is only natural that some people believe that there is evidence that even in the absence of human impact, we will enter another ice age. But our concern is the face of the earth's greenhouse gases increasing so quickly has been a threat to life on Earth. Human activities have led to global warming, such as deforestation, which means that a reduction of carbon dioxide into oxygen, and the burning of fossil fuels lead to sea-level rise, Antarctic melting snow and ice temperature. Mean sea-level rise can be used to reduce the land area, melting the ice means that the release of any hazardous substances may also cause further sea-level rise. The increase in temperature of bacteria and viruses will also provide a

关于全球环境经济论文范文2篇

关于全球环境经济论文范文2篇 关于全球环境经济论文范文一:全球环境变化与健康 摘要:全球环境变化条件下的人类安全与健康问题,是20世纪末提出的重要问题。全球环境变化是指全球范围的大规模的环境变化,本文主要从大气组成的改变、土地利用变化、城市化、全球化等方面对人类健康产生的影响做了一些阐述。同时提及了我国环境变化对人类健康的影响。 关键字:全球环境变化;人类健康;气候变化 一、全球环境变化 随着对全球环境变化的研究进展,科学家逐渐认识到上述环境变化的各个方面不仅加剧了空气、水污染等环境污染带来的健康问题,而且由于不良生活方式、大城市拥挤的居住环境、就业竞争的压力、贫富差距等,影响人的精神状态并引起的多种慢性疾病和疾病谱的明显改变等一系列安全与健康问题。目前,人类健康已成为全球环境变化研究的核心内容之一。 虽然目前为止尚未完全搞清楚全球环境变化的机制、各种变化之间的联系以及全球环境变化对人类健康的影响,但已有的研究表明全球气候变化、臭氧层损耗、土地利用和土地覆盖的变化、生物多样性的丧失、淡水资源、食物生产系统改变以及城市化等问题从多方面给人类健康带来直接和间接的影响。(图为人类对全球环境的影响及全球环境变化对人类健康的影响途径)

二、全球大气组成改变及其健康影响 气候变化对人类健康的影响是多方面的,而且预计消极影响会大大超过其积极影响,其影响有直接和间接两种,且以间接影响为主。 对人类和其他动物而言,其影响包括免疫系统抑制;增加严重晒斑、白内障和表皮损害的发病率;减少维生素d的合成;导致皮肤癌。臭氧层臭氧每减少1%,皮肤接触到紫外线辐射量就会增加2%,皮肤癌的患病率就要增加4%⑵。uv辐射对粮食作物和海洋浮游植物产生不利影响,会破坏食物链从而影响到人类健康.uvb辐射在低空大气层的增加会催化氮氧化合物和碳氢化合物产生高浓度的大气污染物,从而对人类的呼吸系统产生不良影响。大气成分变化对健康的另一重要影响就是臭氧层破坏使人类紫外线辐射暴。 三、土地利用/土地覆被变化与健康问题 土地利用/土地覆被变化对全球环境变化影响范围从改变大气层的组成成分到对不同尺度地球生态系统改变等多个方面,往往伴随着生物多样性的消逝,特别是生境的消逝,分裂和改变。土地利用/土地覆被变化对人类健康的影响首先考虑的就是生物多样性丧失对健康的影响。 生物多样性为我们提供了大量维持生命所需的产品和服务,并在保护生命健康和确保生命对变化所带来的压力具有恢复力方面发挥着重要作用。 首先,农业、林业、畜牧业和渔业的许多品种都来自野生物种,生物多样性还是医药的源泉,生物多样性的丧失意味着我们

全球变暖 选修课论文 3000字

全球气候变暖是一种“自然现象”。由于人们焚烧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,也就是常说的“温室效应”,导致全球气候变暖。近100多年来,全球平均气温经历了冷-暖-冷-暖两次波动,总的看为上升趋势。进入八十年代后,全球气温明显上升。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,既危害自然生态系统的平衡,更威胁人类的食物供应和居住环境。 什么是全球气候变暖 全球变暖是指全球气温升高。近100多年来,全球平均气温经历了冷-暖-冷-暖两次波动,总的看为上升趋势。进入八十年代后,全球气温明显上升。 1981~1990年全球平均气温比100年前上升了0.48℃。导致全球变暖的主要原因是人类在近一个世纪以来大量使用矿物燃料(如煤、石油等),排放出大量的CO2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,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,既危害自然生态系统的平衡,更威胁人类的食物供应和居住环境。 出现全球变暖趋势的具体原因是,人们焚烧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进入了地球的大气层。政府间气候变化问题小组根据气候模型预测,到2100年为止,全球气温估计将上升大约1.4-5.8摄氏度(2.5-10.4华氏度)。根据这一预测,全球气温将出现过去10,000年中从未有过的巨大变化,从而给全球环境带来潜在的重大影响。 为了阻止全球变暖趋势,1992年联合国专门制订了《联合国气候变化框架公约》,该公约于同年在巴西城市里约热内卢签署生效。依据该公约,发达国家同意在2000年之前将他们释放到大气层的二氧化碳及其它“温室气体”的排放量降至1990年时的水平。另外,这些每年的二氧化碳合计排放量占到全球二氧化碳总排放量60%的国家还同意将相关技术和信息转让给发展中国家。发达国家转让给发展中国家的这些技术和信息有助于后者积极应对气候变化带来的各种挑战。截止2004年5月,已有189个国家正式批准了上述公约。 全球变暖的历史与预测 根据仪器记录,相对于1860年至1900年期间,全球陆地与海洋温度上升了摄氏0.75度。自1979年,陆地温度上升速度比海洋温度快一倍(陆地温度上升了摄氏0.25度,而海洋温度上升了摄氏0.13度)。根据卫星温度探测,对流层的温度每十年上升摄氏0.12度至0.22度。在1850年前的一两千年,虽然曾经出现中世纪温暖时期与小冰河时期,但是大众相信全球温度是相对稳定的。 根据美国国家航空航天局戈达德太空研究所的研究报告估计,自1800年代有测量仪器广泛地应用开始,2005年是最温暖的年份,比1998年的记录高了摄氏百分之几度。世界气象组织和英国气候研究单位也有类似的估计,曾经预计2005年是仅次于1998年第二温暖的年份。 在人类近代历史才有一些温度记录。这些记录都来自不同的地方,精确度和可靠性都不尽相同。在1860年才有类似全球温度仪器记录,相信当年的记录很少受到城市热岛效应的影响。从最近的千禧年内的多方记录所展示的长远展望,在过去1000年的温度记录中可以看到有关的讨论及其中的差异。最近50年的气候转变的过程是十分清晰,全赖详细的温度记录。到了1979年,人类更开始利用卫星温度测量来量度对流层的温度。

全球变暖英语文章

The serious problem of earth--Global Warming Recent years, we are in a good environment, generally, and do not feel the cold. Why? Do you think this is a problem of earth? Certainly, it is a serious problem of earth—Global Warming. More and more climate experts are beginning to pay more attention to the threats of global warming and figure the solution, caused by greenhouse effect. According to the authoritative survey, the reason are as follows .Firstly, the amount of greenhouse gas, such as carbon dioxide, rapidly increasing in atmosphere. Secondly,the direct effect of global warming is glaciers melting. Thirdly, effect of global warming is that the sea level is rising along with the glaciers melting. Certainly, these things bring many dangerous things. For example,first, the global surface temperature has risen about 3.5 centigrade during the past 100 years and the rate of temperature rise is speeding up. The effects of global warming, including glaciers melt, sea level rise and crisis of human living, is from bad to worse. Second, with the global temperature increasing, the glaciers of north and south poles are melting gradually. Third,the animals, which live on the south and north poles, is facing the threat of extinction in future. For example, the number of polar bear is decreasing year by year. As the sea level rises, a large number of islands are facing the threat of being devoured. In fact ,in order to survive, the devoured countries must look for other lands to live. A more terrible thing is coming stealthy. In the process of searching for other lands, a war, which fights for living space is likely to break out. The worst effect is that global warming is influencing the survival of human being. The earth is a complete ecological system. As we mentioned before, the melting glaciers,the rising sea level and the potential war, will aggravate the wreck of ecological system. Due to the wicked environment, the human can not live on the earth any longer in future. How terrible the effects are! If we do not hope to encounter the awful effects, we must pay more attention to aware of the bad effects of global warming and put forward forceful and effective measures to prevent the aggravation of global warming.

气候变暖 议论文

全球变暖 当哥本哈根气候大会召开时,全球气候变暖的警钟就已经敲响了。你听到了吗! 随着人类高科技发展进程越来越快,科学随之产生的副作用逐渐体现出来,全球变暖就是一个例子。炎热天气,空调成为了人们的“救星”,但人们想过使用空调的负面影响吗?空调排放的气体中含有大量导致全球变暖的气体甲烷输送到外面。同时,空调还会让你家电表尽快清零,所以还是要尽量少的使用空调。 另一个原因则是:二氧化碳!汽车尾气与工厂废气中含有大量二氧化碳,而二氧化碳又是导致温室效应组要成分。在21世纪这个汽车和工厂数量暴涨的时代,汽车尾气的排放有增无减,天中乌云滚滚而来,真是令人堪忧。有人统计,美国人均二氧化碳排放量已达到了20吨一年!中国每年的二氧化碳排放量人均排放量也有2.51吨一年!当然,我们周围的环境正在以光速恶化着。 森林锐减,水资源破坏,生态链严重被破坏,大量土地贫瘠,水污染严重,也是重要的原因。据统计全世界10%的河水被污染,新鲜的淡水供应成了问题。臭氧层被严重破环,南北极出现臭氧层洞,也加剧了环境的恶化。如此恶性循环,最终会导致人们的生活被严重影响。 气温攀升,海面上涨,冰川融化,岛国被淹。这一切,都严重影响了人类的生存。但我们无法向上苍哭爹喊娘,因为这一切悲剧都是人类亲自酿成的。 在这样的紧要关头只要我们舍弃塑料袋,多乘公共交通工具,将垃圾认真分类,变废为宝……注意生活中的点点滴滴,那么一切就还都不晚。我们还是可以将昨日重现,还鸟儿一片蓝天,还鱼儿一汪清潭,还百兽一片森地,最重要的是回到我们的家! 如今,日本,英国,美国等国家纷纷行动起来,我们虽然也采取了行动,但,对于一个有13亿人口的泱泱大国,这一点,还是远远不够的,所以大家一起加油吧!一起卷起袖子大干一场吧!
