1、3分钟关于全球变暖的英语演讲稿5篇 3分钟关于全球变暖的英语演讲稿1 In recent years do you think the weather suddenly turned hot had the coolautumn now almost until early October the hottest day in August has reached morethan 40 degrees. These is different from normal vision we have ourselves toblame the curse. Today the term globa
2、l warming has gradually penetrated into our life. Theword sounds very academic even feel very far away from us so some people arenot. In fact the effects of global warming is beyond our imagination: globalprecipitation redistribution glaciers and permafrost melt rising sea levels andso on. Both harm
3、 the natural ecosystem balance more threatening human foodsupply and living environment. Now that you have aware of the dangers of global warming you should go topredict and improve it. Imagine if global warming is melting in the 21st centurythe global average temperature rising gradually so the nex

Scientists aroundthe world agree points out that the earth s average temperature has increasednearly 1 . Due to all the early warning informa

Scientists will have the most advancedcomputer data input model to estimate the earth can face the future. Predictionresults are worrying. Forty years

Currently half of the world s biodiversity in the amazonrainforest but the rainforest is likely to turn into a piece of barren land bythe end of the cen

This isnot a crazy fantasy if humans don t stop destroying the environment it willbecome a reali

In order to save the planet we should try to be: don t open airconditioning use recycled paper environm

Thank you all! 3分钟关于全球变暖的英语演讲稿2 Many people b
10、elieve that human activity is causing the earths temperatureto rise. They say that this global warming will have dreadful consequences forour environment, such as drought and flooding. The earths temperature is rapidly changing. As a result there has been alot of climate change such as heat waves, d
11、roughts and floods. 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
12、 public informed. 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 conference
13、s to discuss theeffects 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 polluti
14、on. Finally, everybody 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 alsoen
15、courage the public 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
16、 that governments cando to prevent global warming. They should involve companies, support scientistsand encourage individuals to protect the planet. 3分钟关于全球变暖的英语演讲稿3 global warming the gradual increase of the temperature of the earth s loweratmosphere as a result of the increase in greenhouse gases
17、since the IndustrialRevolution. The temperature of the atmosphere near the earth s surface is warmedthrough a natural process called the greenhouse effect. Visible shortwave lightcomes from the sun to the earth passing unimpeded through a blanket of thermalor greenhouse gases composed largely of wat
18、er vapor carbon dioxide methanenitrous oxide and ozone. Infrared radiation reflects off the planet s surfacetoward space but does not easily pass through the thermal blanket. Some of it istrapped and reflected downward keeping the planet at an average temperaturesuitable to life about 60F (16C). Gro
19、wth in industry agriculture and transportation since the IndustrialRevolution has produced additional quantities of the natural greenhouse gasesplus chlorofluorocarbons and other gases augmenting the thermal blanket. It isgenerally accepted that this increase in the quantity of greenhouse gases istr
20、apping more heat and increasing global temperatures making a process that hasbeen beneficial to life potentially disruptive and harmful. During the pastcentury the atmospheric temperature has risen 1.1F (0.6C) and sea level hasrisen several inches. Some projected longer-term results of global warmin
21、ginclude melting of polar ice with a resulting rise in sea level and coastalflooding; disruption of drinking water supplies dependent on snow melts;profound changes in agriculture due to climate change; extinction of species asecological niches disappear; more frequent tropical storms; and an increa
22、sedincidence of tropical diseases. Improved automobile mileage reforestation projects energy efficiency inconstruction and national support for mass transit are among relatively simpleradjustments that could significantly lower U.S. production of greenhouse gases.More aggressive adjustments include
23、a gradual worldwide shift away from the useof fossil fuels the elimination of chlorofluorocarbons and the slowing ofdeforestation by restructuring the economies of developing nations. In 20_ theBush administration proposed several voluntary measures for slowing the increasein instead of reducing emi
24、ssions of greenhouses gases. 3分钟关于全球变暖的英语演讲稿4 Global Warming There 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 degreecelsius). The warmest since the mid 1800s was the 1990s. The hottest yearsrecorded were
25、 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. If the ice caps melt, a vast majority of ourcountries borders will be under water. Monum
26、ents 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 planet? The answer is simpler than you may think. You dont have to go miles awayfrom
27、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 helpout a local wildlife group and ask to plant a tree. Trees, when fully grown,will
28、 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 create roads orhomes. Something as simple as walking instead of taking the car will help
29、 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 vehicle or can Iwalk? When you are at home, and your getting a little cold. Put a
30、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 toavoid imported goods. The more foreign food that we import the more pollutionfrom a
31、eroplanes 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 weight in CO2 each year. A small efficientdiesel car covering the same distance
32、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 electricity. Reduce, reuse and recycle. Only buy what you need; dont stock thec
33、upboards 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 televisions and heaterswill help the environment, as well as save you money. If everybo
34、dy 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. 3分钟关于全球变暖的英语演讲稿5 The topic of global warming is attracting the attentions
35、of countries allover the world. This global warming is on such a scale that it will wreak havocon both poor and rich countries. It could even make large sections of the earthuninhabitable. What have caused global warming? The theory and evidence strongly suggestthat human-related emissions of carbon
36、 into the atmosphere is causing, and willin the future cause, significant global warming. How we should fight global warming? We should be taking active steps now tocurb emissions and we should be engaging in international co-operation to do so.A simple natural way to fight global warming is to have
37、 escalating Taxes oncarbon emissions. There is a simple reason why this is the ideal remedy: carbonemissions into the atmosphere constitute a nuisance to everybody on the planet;so those who make this nuisance should pay for their actions. A furtherrecommendation is that there should be large-scale
38、government support forresearch into new technology that will reduce carbon emissions. China is the rising economic star; and if it also wants to assert worldleadership status, it is a good opportunity for China to show the world that ithas a moral commitment and the will to fight global warming. 3分钟关于全球变暖的英语演讲稿7
