气候变暖议论文第一篇：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！第二篇：气候变暖与我-英文Climate change and IThe United Nations Climate Change Conference in Copenhagen, the Danish capital, held in December 2009, made the subject of climate warming as the world's most hot topic of the global environmental field.The phenomenon of global warming appeared as early as the second half of the last century, concerned by scientists around the world, while during three decades nearly, the warming trend has not changed but increased, bringing a series of serious results.However, faced with global warming, different people have different views.Some people believe that global warming is entirely nature's own laws, with which human activity has nothing to do;someother people recognize it’s being more hot but believe that it will not lead to that serious consequences the scientists imagined.In my opinion, there is no doubt that global warming and human activities are closely related.Since the result of climate warming is very serious, we need to make effective action to control global warming.The following will be divided into five parts, the first section is the introduction, and the second one will analyze why human activity causes global warming;the third part will analyze the serious consequences of global warming;the fourth part will discuss that what human beings, especially ordinary people can do for the control of global warming;the last part is a summary text of this essay.Earth observations indicate that climate warming is mainly caused by human activity, which may be a good thing as it shows that human beings can work to change the trend of global warming.Although we can not rule out natural variability is alsoa reason of climate warming, but the observed climate change in the past few decades is likely mainly caused by human activity, which caused a great mass of carbon dioxide.Human factors include the rapid increase in population, the use of fossil fuels, all of which will bring a lot of carbon dioxide.And the same result would be caused by the destruction of forests, because forests have ability of absorbing carbon dioxide.Human activity leading to climate warming is mainly industrial production activities, particularly in the developed industrialized countries, however people's daily life, such as the use of air conditioners, contribute to climate warming as well.Those who believe that human activity does not cause global warming people, either is poor of scientific knowledge, or is no sense of responsibility for the security of all humanity and the survival of future generations.Then, let us take a look at global warming in terms of what kind of disaster it means for human.According to the scientists predict, climate warming will lead to a series of serious consequences, including the followings.First, the Earth will have more space to become ocean, floods are becoming increasingly frequent.The chance of flooding suffered and other natural disasters will increase;the capacity of humanbeings against these disasters will be challenged.Second, the water temperature increasing could make the Antarctic Peninsula and the Arctic Ocean ice melt, which is the direct cause of rising sea levels, polar bears and walrus are likely to die out at the same time.Thirdly, many small islands and coastal cities will be inundated, while the world's population live in the largest cities like New York, Shanghai, Mumbai, Tokyo, most of which locating on the coast side, which means that if temperatures continue to rise, the vast majority of people have to move to higher altitudeareas.Fourth, people will suffer the food shortage, because agricultural production is deeply dependent on climate.Climate warming will make many places dry, hot, not suitable for planting crops.A severe food problem will become even more severe.From the serious consequences climate warming will bring about, we can see, human beings must act to combat global warming as controlling global warming is related to global human survival.Finally, to face climate warming, mankind is not the inability to be able to, because human activity is the main reason for global warming, as the Chinese saying goes put it, “ Let him who tied the bell on the tiger take it off ”, human beings can control the climate warming, as long as they ready.So, what human beings should do to reduce carbon dioxide emissions to control global warming then? For the politicians from various countries, who run the world, is to reach a consensus for responding to the problem of global warming.Developed countries should, through financial and technical assistance, help developing countries improve their capabilities to reduce carbon dioxide emissions.Ordinary people like me, can also contribute to controlling global warming.For example, we should reduce the use of disposable chopsticks, which will help to reduce deforestation;we should reduce the use of air conditioners, refrigerators and other appliances, which will directly reduce carbon dioxide emissions;we should choose to walk or ride a bicycle at most time instead of the ride on cars and other motor vehicles, to reduce energy use and ultimately reduce carbon dioxide emissions.We can really do so many things as long as we want to;if everyone make a little bit of contribution, controlling global warming is no longer impossible.In conclusion, the scientific observations indicate that climate warming is mainlydue to excessive carbon dioxide emissions caused by human activities;climate warming will bring a variety of serious consequences include sea-level rise;the common human need immediate action to reduce carbon dioxide emissions to curb global warming.As long as each of us is making efforts towards this goal, we were able to better control global warming to make the environment more suitable for the survival of humanity.2009年12月份在丹麦首都哥本哈根召开的联合国气候变化大会使气候变暖这一话题成为全球环境领域最受关注的话题。
