1、气候变暖的英文演讲稿演讲稿也称演说词,是在大会上或某些公开场合发表和宣扬的文稿。演讲稿一般具有宣传、鼓动、教育和欣赏等作用,能够把演讲者的观点、主张与思想感情传达给听众以及读者,让他们能够信服并且在个人的感情和思考上产生共鸣,具有较强的感染力。演讲稿的质量直接决定了演讲的效果。同议论文一样,演讲稿也具备论点鲜明、逻辑性强等特点,但绝不是一般的议论文。下面一起看下为大家精选的演讲稿范文。气候变暖的英文演讲稿1People around the world may feel that the climate has been getting steadilywarmer and warmer in
2、 recent years. Places which used to be abundant in snowfallhave frequently experienced snowfree(无雪的) winters. Drought lasts longer in somedry areas. People find that without air conditioners they could hardly work orfall asleep on hotter summer daysg.The side effects of global warming are alarminS.
3、A warmer global climatemelts the ice caps, raising sea levels. What is more, it disturbs weatherpatterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lotfrom disasters relevant to global warming.To stop global warming we should make immediate and continual efforts. Wehope the s
4、ituation will soon change. Global warming catches and holds ourconcern, for it affects us and will affect our later generations. We cannot waitany longer. Do it right now.气候变暖的英文演讲稿2Many people believe that human activity is causing the earths temperatureto rise. They say that this global warming wi
5、ll have dreadful consequences forour environment, such as drought and flooding.What should governments do to help prevent global warming? Give reasons foryour suggestions.The earths temperature is rapidly changing. As a result there has been alot of climate change such as heat waves, droughts and fl
6、oods. Scientistsbelieve that this is the result of human activity, which is polluting theEarths atmosphere. This could become a disaster if governments do not act tohelp prevent global warming. They can act in three ways; by supporting research,by making laws and by keeping the general public inform
7、ed.Firstly, governments can support research. For example, they shouldencourage companies to develop vehicles that cause less pollution. They shouldalso support alternative sources of electricity from wind and water rather thanfrom oil and coal. As well, they should sponsor conferences to discuss th
8、eeffects of greenhouse gas emissions and possible solutions to the problem.Secondly, they should make laws that limit the amount of greenhouse gasesthat companies can emit. Private companies should be rewarded for followingthese laws. They should also be punished for creating pollution.Finally, ever
9、ybody is affected by global warming. Therefore, it isimportant that governments involve individuals in the problem solving process.For example they should encourage households to save as much energy as possibleby using more efficient light bulbs or less hot water. They should alsoencourage the publi
10、c to recycle, and this should be compulsory for everyone.Another way of saving energy is by public transport systems. Governments shouldspend money on public transport to make it as easy as possible for the public tosave energy.In summary, it is clear that there are a lot of things that governments
11、cando to prevent global warming. They should involve companies, support scientistsand encourage individuals to protect the planet.气候变暖的英文演讲稿3After investigation, we found that caused the main reason for the increaseof greenhouse gases is human activity. Carbon dioxide, for example, before thehuman s
12、ociety to realize industrialization in the early 19th century, theconcentration of carbon dioxide in the atmosphere to 270 parts per million, andin 1988 to rise to 350 PPM. Atmospheric co2 concentration increased there aretwo main reasons: first, the dramatic increase in population and the developme
13、ntof industrialization, human society, consumption of fossil fuels has increaseddramatically, combustion produces a large amount of carbon dioxide into theatmosphere, increase the concentration of carbon dioxide in the atmosphere:second forest reduces the amount of carbon dioxide absorbed by plants
14、use, aspeed reduction in carbon dioxide is consumed, also leading to higherconcentration of carbon dioxide in the atmosphere. Greenhouse gases than carbondioxide, such as methane, CFCS (freon), nitrogen oxide and so on also need toincrease a different level.Although there are many uncertainties, it
15、is clear that global warming onclimate, rainfall, and the influence of sea level and the resulting impact onhuman settlements and the ecosystem is extremely complex, must be given theattention they deserve. Think this kind of influence is irrelevant in the longrun view is irresponsible.The main caus

Such as temperature height, deputy polarregions may be mo
17、re suitable for human habitation, under appropriate conditions,higher co2 concentration can promote the photosynthesis, which plants have ahigher rate of carbon sequestration, lead to the increase of plant growth,namely the stimulation effect of carbon dioxide, which is the positive impact ofglobal
18、warming. But compared with the positive impact, the negative impact ofglobal warming on human activity will be more vast and far-reaching.气候变暖的英文演讲稿4There 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 degre
19、ecelsius). The warmest since the mid 1800s was the 1990s. The hottest yearsrecorded were 1997, 1998, 2001, 2002, 2003.The United Nations panel on climate change projects that the globaltemperatures will rise 3-10 degrees fahrenheit by the centurys end - enough tohave the polar caps all but melted. I
20、f the ice caps melt, a vast majority of ourcountries borders will be under water. Monuments and great buildings, as well ashomes 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 weas individuals do our part to help save the
21、 planet?The answer is simpler than you may think. You dont have to go miles awayfrom home to protest, or spend masses of money. If you try to follow the fewsimple steps that I shall now give you, you will have started to help usall.Firstly, plant a tree. This could be easier than it sounds. Join or
22、helpout 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 againstthe demolition of the rainforests. This is the same principle, we need the treesto cool our planet and yet they are chopping them down to crea
23、te roads orhomes.Something as simple as walking instead of taking the car will help reducepollution. As well as stopping pollution, you are giving yourself exercise,something important for our bodies. So the next time you get into your car, oryour motorbike, think - do I have to make this journey by
24、 vehicle or can Iwalk?When you are at home, and your getting a little cold. Put a jumper on anddo not adjust the heating. The extra heat produced by our homes also affects theplanet. So try wearing an extra layer in winter.If possible, buy your fruit and vegetables from local suppliers. And try toav
25、oid imported goods. The more foreign food that we import the more pollutionfrom aeroplanes and boats it will create.Keeping to the speed limit can also help the environment. The more youspeed the more petrol you are going to use, making the pollution higher. Also,SUVs make about six times their own
26、weight in CO2 each year. A small efficientdiesel car covering the same distance not only uses much less fuel; it makes twothirds less.If possible use solar energy, after all it is free; all you need to buy isthe equipment. You can get much of your hot water and heating from the sun andeven generate
27、electricity.Reduce, reuse and recycle. Only buy what you need; dont stock thecupboards with things you may or may not use. Reuse whatever you can, likecontainers and paper, and recycle what you cannot reuse. It really is as simpleas that.Finally turning off unused sources of power such as television
28、s and heaterswill help the environment, as well as save you money.If everybody stuck to these rules, we would be doing a great thing byprotecting the earth. So please take into consideration what I have said, andtry to do your part. After all, it will be our next generation that will feelthe effects
29、.气候变暖的英文演讲稿5With the development of economy, more and more greenhouse gases are beingdischarged into the air. CO2 makes up about 70% of the greenhouse gases, whichis considered to be one of the greatest causes of global warming. It has harmfuleffects, causing the sea level to rise and many natural d
30、isasters to strike.So we must take effective measures to save our planet. First, we should usemore clean energy and less coal and oil. Second, we should go to work on foot orby 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 thehabit of saving energy in our daily life.
