摘要：21世纪的世界，战争和饥饿只会发生在局部地区，绝对不会影响到整个世界；然后，这并不表示没有其他威胁全世界的因素。这几年，无论是是欧美、中亚还是南北极的人们都明显感受到了与往年不一样的气候，极端天气发生的的频率不断提高，海平面日益上升，冬天逐渐在消失，欧亚大陆不在四季分明，南北极不在万里冰封。造成这一变化的正是全球性的气候变暖。全球气候变暖带来的影响绝对不止上面所举的例子，它正在成为继战争、饥荒之后对世界影响最大的事件之一。下面我们就从全球变暖产生的原因、后果以及应对措施等方面来探讨了解，唤起人们对这一问题的重视。关键词：气候 变暖 现象 措施

一、全球气候变暖给地球带来的影响

世界上很多国家都在担心全球变暖这一问题，都纷纷在寻找遏制和应对这一现象的措施，其中也包括各个国家的领导人。那么，我们凭什么说地球在变暖，而且地球变暖正在威胁着人类的生存，我们必须刻不容缓的找到应对它的措施呢？

其实，只要你是一个热心生活的人，你就会在很多方面发现今天的气候跟往年有很大的不同，很多人都会在感叹好多年都没看到下很大很大的鹅毛大雪了，那些记忆似乎很遥远了；就拿今年来说吧，明明眼看就要立冬了，可气温似乎并不是很冷，至少比起往年要热的多，晚上睡觉的时候还时常会受到早该消失了的蚊子的侵扰。这些都是气候变暖的表现。

上面说的现象都是我们自己身边的感受，至于全球变暖到底给我们带来了怎样的影响，我们从以下几个方面来认识。①全球气温将升高。从现在起到本世纪末，人类将面临史无前例的气温上升。就本世纪而言，较乐观的预测是全球气温将升高1.4摄氏度，最悲观的设想则认为，全球气温将上升近6摄氏度。最好的例子就是纽约市今年1月6日最高温度达到21.7摄氏度，打破了1950年创下的17.2摄氏度的纪录。②海平面将升高。在本世纪内，海平面将可能升高20厘米至80厘米。原因是气候变暖导致海水膨胀，冰川和海上浮冰层融化(北极浮冰层厚度50年来减薄了40%)。在格陵兰，自1988年以来，冰川融化速度加快，已提高了2倍。海平面升高就可能导致某些岛屿国家或者沿海城市被淹没。③近几年来，极端气候现象增多。大多数专家认为，在今后50年内，法国每2年就会出现一次2003年那样的酷热(当年造成1.5万人死亡)。干旱将给农业造成严重影响(气温升高2摄氏度将可能使农业减产30%)。在欧洲南部，降雨量将明显减少。④据绿色和平组织说，到2050年，疟疾造成的死亡人数(每年在100多个国家造成250万人死亡)将可能翻一番，并将越过地中海在西班牙、意大利和法国登陆。其他严重的热带疾病也将随之而来，如通过飞蝇传播而造成消化道疾病的尼罗河病毒或利什曼病毒。另外，哮喘患者也将增加，因为炎热的天气将带来更多的花粉。⑤援引法国绿色和平组织负责人雅多的话说，如果气候变暖继续照此速度发展，那么到2050年将会有百万物种消失，即占各种生物种类的40%，而法国本土将会有20%的物种消失。北极熊和北极的其他动物将会像珊瑚礁水域的鱼一样成为主要受害者。德国的一项研

究表明，气候变暖将威胁到鱼的生存，因为气候变暖会引起水中氧气减少。这仅仅是全球气候变暖带来的其中5个最明显的影响。

二、全球变暖产生的原因

全球变暖真实而恐怖的威胁着人类赖以生存的地球，因此，拯救地球遏制全球变暖已经刻不容缓，我们必须在尽量短的时间内寻找到解决问题的途径。然而要找到解决的方法就有必要了解产生问题的原因，找到问题的源头才能治本。在世界人民的共同努力下，我们找到了全球变暖的几大原因，可能不全面但也大致搞清楚了变暖的缘由。这些原因大致有1.人口剧增因素，近年来人口的剧增是导致全球变暖的主要因素之一。同时，这也严重地威胁着自然生态环境间的平衡。这样多的人口，每年仅自身排放的二氧化碳就将是一惊人的数字，其结果就将直接导制大气中二氧化碳的含量不断地增加，这样形成的二氧化碳“温室效应”将直接影响着地球表面气候变化。2.大气环境污染因素，目前，环境污染的日趋严重已构成一全球性重大问题，同时也是导致全球变暖的主要因素之一。现在，关于全球气候变化的研究已经明确指出了自上个世纪末起地球表面的温度就已经开始上升。3.海洋生态环境恶化因素，目前，海平面的变化是呈不断地上升趋势，根据有关专家的预测到下个世纪中叶，海平面可能升高50cm。如不采取及对措施，将直接导致淡水资源的破坏和污染等不良后果。另外，陆地活动场所产生的大量有毒性化学废料和固体废物等不断地排入海洋；发生在海水中的重大泄(漏)油事件等以及由人类活动而引发的沿海地区生态环境的破坏等都是导致海水生态环境遭破坏的主要因素。4.土地遭侵蚀、沙化等破坏因素，造成土壤侵蚀和沙漠化的主要原因是不适当的农业生产。众所周知良好的植被能保持水土流失。但到目前为止，人类活动如为获取木材而过度砍伐森林、开垦土地用于农业生产以及过度放牧等原因，仍在对植被进行着严重的破坏。目前全世界平均每分钟有20公顷森林被破坏，10公顷土地沙化，4.7万吨土壤被侵蚀。土壤侵蚀使土壤肥力和保水性下降，从而降低土壤的生物生产力及其保持生产力的能力；并可能造成大范围洪涝灾害和沙尘暴，给社会造成重大经济损失，并恶化生态环境。5.森林资源锐减因素，在世界范围内，由于受自然或人为的因素而造成森林面积正在大幅度地锐减。6.地球周期性公转轨迹的变动，地球周期性公转轨迹由椭圆形变为圆形轨迹，距离太阳更近。根据某科学家的研究地球的温度曾经出现过高温和低温的交替，是有一定的规律性的。从这些原因中我们可以总结出这样一个规律，其实导致全球变暖的最根本原因就是温室气体——二氧化碳的大量排放和增加。

三、应对全球变暖的措施

了解全球变暖给我们带来的影响是为了让我们对这一问题产生足够的重视，而分析产生这一问题的原因是为了对症下药，更有效的遏制和防范全球继续变暖。因此，在上文中阐述了全球变暖的影响和原因之后，我们就有必要去寻找解决问题的方法，即应对全球变暖的措施。

我们从以上的原因分析中已经知道，温室气体是造成全球变暖的主要原因，所以我们应该重点从温室气体下手。首先我们要想办法努力减少温室气体的排放，其实当下国际上的很多国家都认识到了这一点，并从碳排放着手试图走出全球变暖的困境。欧盟：政策机制保障低碳经济发展；美国：通过立法来保障低碳经济发展；日本：将发展 “低碳经济” 定位为创建 “低碳社会”;中国：通过政策法令进行低碳减排。.国际经济向低碳经济转型，世界进

浅谈全球气候变暖

入低碳时代。2003 年英国首先提出“低碳经济”概念，在后来的“巴厘路线图”中，低碳经济被进一步肯定,2008年的世界环境日主题定为“转变传统观念,推行低碳经济”。2009年12月7日至12月18日，联合国气候变化大会在哥本哈根举行，发表了不具有法律约束效力的《哥本哈根协议》，就发达国家实行强制减排和发展中国家采取自主减缓行动作出了安排，并就全球长期目标、资金和技术支持、透明度等焦点问题达成广泛共识。这是国际上从减少碳排放的角度出发的，其实，如果在世界范围内我们提高对森林和植被的重视，不肆意破坏森林和植被，科学合理的利用这些资源，更重要的是我们可以植树造林恢复植被，这样对于碳的吸收是很有帮助的。

另外，我们作为一个普通的世界公民，虽然不能对世界上大规模的碳排放产生重要影响，我们的力量似乎微不足道，但团结的力量是伟大的，我们可以从身边的小事做起，为减少碳排放做出自己的一份贡献。比如，我们在平时的生活、工作中可以减少一次性筷子等一次性物品的使用，少用或者不用塑料袋，草稿纸反复使用，多步行或者乘坐公共交通工具少开车，随手关灯少开空调等等。这些都是我们力所能及的事情，如果我们大家都这样做了，那对 缓解全球变暖是很有帮助的。

四、结束语

21世纪我们都是世界公民，地球的安危就是我们自己的安危，全球气候变暖威胁着整个人类的生存和发展，为了我们的子孙后代，也为了我们薪火相传的人类文明，我们必须团结起来，用我们每个人的力量拯救地球，阻止地球越来越热。

全球气候变暖演讲稿400篇三

1．one of the effects of global warming is the destruction of many important ng and erratic climate conditions will put our ecosystems to the test, the increase in carbon dioxide will increase the evidence is clear that global warming and climate change affects physical and biological will be effects to land, water, and y today, scientists are seeing the effects of global warming on coral reefs, many have been bleached and have is due to warmer ocean waters, and to the fact that some species of plants and animals are simply migrating to better suited geographical regions where water temperatures are more g ice sheets are also making some animals migrate to better effects the ecosystems in which these plants and animals l climate models have been made and they predict more floods(big floods), drought, wildfires, ocean acidification, and the eventual collapse of many ecosystems throughout the world both on land and at have been forecasts of things like famine, war, and social unrest, in our days are the types of effects global warming could have on our planet.2．another important effect that global warming will bring is the loss and endangerment of many you know that 30 percent of all plant and animal species alive in the world today are at risk of extinction by the year 2050 if average temperatures rise more than 2 to 11.5 degrees mass extinctions will be due to a loss of habitat through desertification, deforestation, and ocean plants and animals will also be affected by the inability to adapt to our climate species will survive though because they will migrate to other parts of the world where they can survive.a good example of that happening is the red fox that has already done red fox used to live mainly in north america, but has migrated now to the like you and me are also in danger, people living in coastal areas will be badly hit if sea levels ification will also be a problem for humans, food may become scarce.3．one very disappointing effect of global warming is war and a decline in the amounts of quality food, water, and land, it could bring an increase in global security threats, and the country sudan for example, in that region global warming has played an important is conflict in sudan, global warming is not the only cause, but it has played its roots of the problem in sudan can be traced back to climate change, and the scarcity of natural conflict in sudan started during a time of intense ists and military analysts are predicting that climate change and the devastation it causes could bring war and sufficient amounts of water and food are running short that is when war can come this brings to light is the fact that ecological crisis and violence are both linked.4．economic calamities are another effect that global warming could hurricane katrina for example, one thing that climate change does is that it brings us more extreme storms like ane katrina resulted in millions and millions of dollars in severe storms and floods occur, crops, homes, businesses, and more all fail, and that costs a lot of money, and it hurts the severe floods occur you also need to make sure that the threat of disease is an katrina resulted in 135$ billion in property really hurt the economy that severe weather does damage it can also raise the price of insurance, and this hurts the everyday ng up a disaster area also costs a lot of too many extreme storms hit in a certain time frame the impact on the economy can be disastrous.5．drought is an effect of global warming that we are already seeing right countries are finding that they are currently receiving more storms and rising waters, while other countries are suffering from the climate of the earth warms, experts from scientific american predict that drought conditions could increase by as much as 66 t will mean a shrinking water supply and a decrease in t can mean a danger for global food production and also mean that several countries experiencing drought could have a major famine on their tly, india, pakistan, and some parts of africa are already experiencing is sad to say but experts are predicting that it will get much important effect global warming is having on our planet, is that it is producing more intense storms and you look at the scientific data concerning storms and floods in the last 30 years, you will see that category 4 and 5 hurricanes have nearly doubled in many people don't know or realize is that warm waters give hurricanes their strenght and scientists today are associating the increase in ocean and atmospheric temperatures to the rate of violent n the years 1905 and 2005 the frequency of hurricanes has been on the 1905 to 1930 there were an average of 3.5 hurricanes per year, 5.1 between 1931 and 1994, and 8.4 between

1995 and 2005 there was a record number of tropical storms that came about, and in 2007 the worst flooding in 60 years hit recently, australia has seen the worst flooding they have had in a long time.6．heat waves are also an effect of global is no secret that temperatures are breaking records in the us and canada and extremely hot summer days are in store for north america and elsewhere if global warming continues are some heat waves facts for you: air pollution in urban areas could get worse with the increased could result in more people having heart attacts, strokes, and asthma en, the elderly, poor, and people of color are more vulnerable to the effects of a heat ists have confirmed that the frequency and duration of heat waves has definitely increased by a lot over the last 50 years.7．one obvious effect of global warming is the shrinking of glaciers, this is happening wherever there are glaciers in glaciers have been in retreat for a long time now as global warming continues to effect many people don't realize though is that it is happening more rapidly now then previously rs don't only recede they also shrink lakes this melting produces can also lead to more lakes are like a cancer that is consuming our world's is a fact that may surprise you: even if all the world's mountain glaciers were to melt, the effect on sea levels would be r, the disappearance of mountain glaciers would have other impacts on nature aside from raising sea levels.8．global warming will also bring a rising of sea levels around the glaciers and polar ice sheets melt, the sea levels will rise more and more, and the sea temperatures will also means more hurricanes, and more flooding due to the rise of the sea effects of global warming nowadays,our world is becoming hotter and we called it“globalwarming”which is to describe the rise of global warming has two sides of effect to the world’s ,the global warming means there is more carbon dioxide in our some plants can grow faster and stronger than is its good on the other hand,the global warming will bring us more disasters than e of the more and more carbon dioxide in the atmosphere,the earth’s temperature is rising day by high temperature will cause many serious the ice of antarctica and arctic ocean begin to that happen, the height of sea level will some terrible disasters will coming,like tsunami and so some countries,for example like japan and some coastal cities will be reason of global warming is that too much industrial emissions and poisonous gases which were made by human beings vented to our ally methane and carbon gases make the temperature rise day that will cause many natural unami,flood, drought and so y ,if we don’t stop, the world will become a death world without fate will like the r main reason of global warming is the fast growing of

the world’s if we don’t control the speed of growing population,the situation will be is it already too late to prevent the global warming?i think it is still not too we plant more trees,produce less greenhouse gases like methane and carbon dioxide,and to control the growing of situation of global warming will be we must to do it first in our daily to work by bus or on foot i think,is the best way to prevent the worse situation of global warming.全球气温变暖的主要原因： 人类活动对气候变化肯定是有变化和影响的。人类燃烧煤、油、天然气和树木，产生大量二氧化碳和甲烷进入大气层后使地球升温，大气中二氧化碳排放量增加是造成地球气候变暖的根源。

the main reason for global warming: human activities definitely have an impact on climate burns coal, oil, natural gas which produced a large amount of carbon dioxide and methane, and it warmed the cause of global warming is the increased carbon dioxide emissions into the atmosphere.造 成的危害:首先是自然生态会发生变化；土地荒漠化，森林退向极地，雨量增加，冬天更湿，夏天更旱，旱涝灾害增加，热带将酷热无比，人类难以生存。其次是两极冰块大面积熔化，使海平面上升，那将使生活在沿海的占世界 1/3的人口无家可归，世界许多港口城市 淹没于一片汪洋之中。

harms: first, to change the natural ecology;land desertification, forest back to the polar regions, increased rainfall in winter, wetter, more droughts in summer, increased droughts and floods, tropical would be extremely hot, human difficult to , the melting polar ice, a large area, so that sea level rise, which will live in coastal areas of the world's 1 / 3 of the population homeless, many of the world port city submerged in a sea : first, to change the natural ecology;land desertification, forest back to the polar regions, increased rainfall in winter, wetter, more droughts in summer, increased droughts and floods, tropical would be extremely hot, human difficult to , the melting polar ice, a large area, so that sea level rise, which will live in coastal areas of the world's 1 / 3 of the population homeless, many of the world port city submerged in a sea of.由于人类活动的影响，中国的气候在 21世纪将继续明显变暖，其中中国北方冬天的变暖趋势最为明显。

作为对比，过去100年中，中国的升温幅度仅为0.5℃到0.8℃。

由于气候暖干，三江平原湿地资源及生物多样性都将减少，濒危物种增加，大面积沼泽湿地将变成草甸湿地。

长江三角洲附近的湿地，则将受到海平面上升的威胁，导致面积减少，质量下降，潮滩地被淹没和侵蚀。

由于气温上升，导致黄河和内陆河地区的蒸发量可能增长15%左右，北方水资源短缺以及南方的洪涝灾害都将加剧。

人 类砍伐森林时进行的焚烧和摧毁所释放的温室气体，占了总碳排放量的 20% 森林可吸收四分之一的总碳排放量，随着它们日益消失，或是成为净排放来源，空气中的二氧化碳将大幅度增加。”

people used to always think that, more than planting trees help slow global warming r, scientists have now pointed out that if global temperatures rise another 2 degrees celsius, the forest but it may become a net carbon dioxide emission absorb carbon dioxide emissions will be;the health of forests, especially tropical forests absorb the greenhouse gas emissions than they are to r, if these forests are destroyed, illness or death, accumulation of carbon dioxide in these forests will be human burning of deforestation and destruction of the release of greenhouse gases, of the total carbon emissions by 20% of the forest can absorb a quarter of the total carbon emissions, as they increasingly disappear, or become a net source of emissions, carbon dioxide in the air will increase significantly.从 以上分析可以看出，影响气候变化的因素极其复杂，天体运行和地球运动的威力比人的影响不知要大多少倍，它可以使天气变热，也能让地球变冷。而人的力量在大自然面前显得非常渺小，连一场台风吹来也只有躲避的份儿，大自然的力量是根本抗御不了的。肆无忌惮地糟践自然，人类必然会受到严厉惩罚。人 类应该尽一切努力，去做好应该也能够做好的事情。大力发展低碳经济已经成了国际社会的共识。
