有关全球气候变暖的英语演讲稿
Global WarmingThere is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). The warmest since the mid 1800’s was the 1990s. The hottest years recorded were 1997, 1998, 2001, 2002, 2003. The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.So now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?The answer is simpler than you may think. You don’t have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help us all.Firstly, plant a tree. This could be easier than it sounds. Join or help out a local wildlife group and ask to plant a tree. Trees, when fully grown, will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?When you are at home, and your getting a little cold. Put a jumper on and do not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.If possible, buy your fruit and vegetables from local suppliers. And try to avoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use, making the pollution higher. Also, SUV’s make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.If possible use solar energy, after all it is free; all you need to buy is the equipment. You can get much of your hot water and heating from the sun and even generate electricity. Reduce, reuse and recycle. Only buy what you need; don’t stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, and try to do your part. After all, it will be our next generation that will feel the effects.

topic of global warming is attracting attentions of countries all over world. This global warming is on such a scale that it will wreak havoc on both poor and rich countries. It could even make large sections of the earth uninhabitable. What have caused global warming? The theory and evidence strongly suggest that human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming.How we should fight global warming? We should be taking active steps now to curb emissions and we should be engaging in international co-operation to do so. A simple natural way to fight global warming is to have escalating Taxes on carbon emissions. There is a simple reason why this is the ideal remedy: carbon emissions into the atmosphere constitute a nuisance to everybody on the planet; so those who make this nuisance should pay for their actions. A further recommendation is that there should be large-scale government support for research into new technology that will reduce carbon emissions. China is the rising economic star; and if it also wants to assert world leadership status, it is a good opportunity for China to show the world that it has a moral commitment and the will to fight global warming.

影响全球变暖的主要原因1工业废气多(CO2),城市热岛效应2臭氧空洞变大，紫外线增强3树林的砍伐，破坏循环 提纲早对了，就这样着手回答
全球变暖演讲稿 800字左右
全球变暖可能造成的影响 全球变暖将给地球和人类带来复杂的潜在的影响，既有正面的，也有负面 的。
例如随着温度的升高，副极地地区也许将更适合人类居住；在适当的条件下， 较高的二氧化碳浓度能够促进光合作用，从而使植物具有更高的固碳速率，导致 植物生长的增加，即二氧化碳的增产效应，这是全球变暖的正面影响。
但是与正 面影响相比，全球变暖对人类活动的负面影响将更为巨大和深远。
今年8月份CCTV报道，由于气候变暖的影响，珠穆朗玛峰的顶峰下降了1.3米。
祁连山冰川缩减危及河西走廊：近年来，祁连山冰川融化比上个世纪70年代减少了大约10亿立方米，冰川局部地区的雪线正以年均2-2.6米的速度上升。
专家分析，冰川退缩，雪线上升除自然气候因素外，另一个主要原因是人口膨胀，超载超牧，过度开垦，乱砍滥伐，滥采地下水有关。
《中国环境报》2004-9-16 1、海平面上升的影响 过去的百年海平面上升了14．4cm,我国上升了11．5cm。
海平面升高的原因，主要是海水热膨胀，当海洋变暖时，海平面则升高。
全球升温会引起地球南北两极的冰山融化，这也是造成海平面上升的主要原因之一。
海平面上升的直接影响有以下几个方面： (1) 低地被淹： 英国加高堤坝应对气候变暖 全球变暖使海平面升高，暴风雨频率增加，这使英国人不得政治面目 加高防洪堤坝。
据英国官方近日公布的统计数据，在过去的20年中，由于泰晤士河的水位随全球变暖而升高，当地政府机构不得不先后88次加高防洪堤坝，以保障伦敦人的生命财产安全。
，据悉，人们现在平均每年4次加高其堤坝。
据估计，在2030年以前，其加高堤坝的频率会达到每年30次。
钟和 中国环境报2004-10-19 (2) 海岸被冲蚀 (3) 地表水和地下水盐分增加，影响城市供水。
（4）地下水位升高。
(5) 旅游业受到危害(海平面上升50米,大连、秦皇岛、青岛、北海、三亚滨海旅游区向后31-366料，沙滩损失24%，北戴河沙滩损失60%。
2002年中国国土资源公报报道，沿海旅游业已成为第一大产业，其产值为2503亿元，占海洋产业总产值的34.6%。
（6） 影响沿海和岛国居民的生活(占世界1／3的人口)，使之受到威胁。
如果极地冰冠融化，经济发达、人口稠密的沿海地区会被海水吞没，马尔代夫、塞舌尔等低洼岛国将从地面上消失，上海、威尼斯、香港、里约热内卢、东京、曼谷、纽约等海滨大城市以及孟加拉、荷兰、埃及等国也将难逃厄运。
2、对动植物的影响 气候是决定生物群落分布的主要因素，气候变化能改变一个地区不同物种的适应性并能改变生态系统内部不同种群的竟争力。
自然界的动植物，尤其是植物群落，可能因无法适应全球变暖的速度而做适应性转移，从而惨遭厄运。
以往的气候变化(如冰期)曾使许多物种消失，未来的气候将使一些地区的某些物种消 失，而人些物种则从气候变暖中得到益处，它们的栖息地可能增加，竞争对手和 天敌也可能减少。
比如说桔子，过去20世纪70年代，它的最北的边界线是在黄 山一线，宣城市也曾经试种过，但到冬天的一场大雪，树木就冻死了。
但现在我 们校园里的桔子树都长得很好。
又如，扬子鳄只生活在宣城、泾县和南陵这样狭 小的地带，如果北界线北移，扬子鳄可能会自然绝种。
这是从我省的局部地区来 讲。
从全国来讲，我国把冬季1月0度等温线作为副热带北界，目前这一界线处 于我国秦岭-淮河一带。
研究发现，气温升高会使这一界线北移至黄河以北，徐 州、郑州一带冬季气温将与现在的杭州、武汉相似。
3、对农业的影响 一年中温度和降水的分布是决定种植何种作物的主要因素，温度及由温度引起降水的变化将影响到粮食作物的产量和作物的分布类型。
气候的变化曾经导致生物带和生物群落空间(纬度)分布的重大变化。
如公元800-1200年北大西洋地区的平均温度比现在高1℃，使玉米在挪威种植成为可能，但到了公元1500-1800年，西欧出现小冰川期，平均气温也只比现在低1-2℃，就造成了挪威一半农场弃耕，冰岛的农业耕种活动则几乎全部停止。
除此之外，全球变暖还会使高温、热浪、热带风暴、龙卷风等自然灾害加重。
因此，全球气温升高后，世界粮食生产的稳定性和分布状况将会有很大变化。
4、对人类健康的影响 人类健康取决于良好的生态环境，全球变暖将成为下个世纪人类健康的一个 主要因素。
极端高温将成为下世纪人类健康困扰变得更加频繁、更加普遍，主要 体现为发病率和死亡率增加，尤其是疟疾、淋巴腺丝虫病、血吸虫病、钩虫病、 霍乱、脑膜炎、黑热病、登革热等传染病将危及热带地区和国家，某些目前主要 发生在热带地区的疾病可能随着气候变暖向中纬度地区传播。
有关全球气候变暖的环境保护英语作文
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.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.

Today, economy is advancing at a fast pace and together with it, the climate. Greenhouse gases is getting more and more and the world ，with its rising temperature, is having a 'fever. Due to the icebergs melting rapidly, the sea level is increasing and who knows when it will drown some of the islands and wipe out civilizations ? Natural disasters are all taking place more often than not. So, is there no help at all? What can we do to slow down the pace of global-warming? First of all, we can use the clean energy which will not pollute the air , the ground or the sea. Some examples are the solar energy, the wind energy and the wave energy. Secondly, we can plant more trees . One way in which the tree can help is that it takes in carbon dioxide , a greenhouse gas, and releases oxygen instead. Isn't this killing two birds with one stone? Lastly, we can reduce the use of cars and walk instead. The cars let off exhaust gases and pollute the earth. If we use our legs instead, we can do our part on saving the earth and even exercise at the same time!
