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1In recent years do you think the weather suddenly turned hot had the cool autumn now almost until early October the hottest day in August has reached more than 40 degrees. These is different from normal vision we have ourselves toblame the curse.Today the term “global warming” has gradually penetrated into our life. The word 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: global precipitation redistribution glaciers and permafrost melt rising sea levels andso on. Both harm 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 to predict and improve it. Imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms thenext round of searing heat the next major natural disasters will happen? China? The United States? Japan? No one knows. The debate has ended. Scientists around the world agree points out that the earth’s average temperature has increased nearly 1 ℃. Due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. Scientists will have the most advanced computer data input model to estimate the earth can face the future. Prediction results are worrying. Forty years later the Himalayan glaciers the water to the survival of millions of people are likely to disappear. The Greenland ice sheet could melt in 50 years. Currently half of the world’s biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land bythe end of the century. Is likely to be the future of the world like in themovie “the day after tomorrow” tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption... This isnot a crazy fantasy if humans don’t stop destroying the environment it will become a reality!However in the warming is also good. Global warming on rice in heilongjiang province has played a large role.Just global warming to human future development is still the do more harm than good.In order to save the planet we should try to be: don’t open air conditioning use recycled paper environmental protection to leave the meat with nitrous oxide don’t use plastic bags R22 by bus; R22; Little drops of life. Actually it’s not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.Thank you all!3分钟关于全球变暖的英语演讲稿2Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.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 possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.3分钟关于全球变暖的英语演讲稿3global warming the gradual increase of the temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.The temperature of the atmosphere near the earth’s surface is warmed through a natural process called the greenhouse effect. Visible shortwave light comes from the sun to the earth passing unimpeded through a blanket of thermal or greenhouse gases composed largely of water vapor carbon dioxide methane nitrous oxide and ozone. Infrared radiation reflects off the planet’s surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward keeping the planet at an average temperature suitable to life about 60°F (16°C).Growth in industry agriculture and transportation since the Industrial Revolution has produced additional quantities of the natural greenhouse gases plus chlorofluorocarbons and other gases augmenting the thermal blanket. It is generally accepted that this increase in the quantity of greenhouse gases is trapping more heat and increasing global temperatures making a process that has been beneficial to life potentially disruptive and harmful. During the past century the atmospheric temperature has risen 1.1°F (0.6°C) and sea level has risen several inches. Some projected longer-term results of global warming include melting of polar ice with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; profound changes in agriculture due to climate change; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases.Improved automobile mileage reforestation projects energy efficiency in construction and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S. production of greenhouse gases. More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels the elimination of chlorofluorocarbons and the slowing of deforestation by restructuring the economies of developing nations. In 20__ theBush administration proposed several voluntary measures for slowing the increase in instead of reducing emissions of greenhouses gases.3分钟关于全球变暖的英语演讲稿4Global 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, 20xx, 20xx, 20xx.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 weas 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 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 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 anddo 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 toavoid 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, andtry to do your part. After all, it will be our next generation that will feel the effects.3分钟关于全球变暖的英语演讲稿5The topic of global warming is attracting the attentions of countries all over the 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 furtherrecommendation 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 xxrtunity for China to show the world that it has a moral commitment and the will to fight global warming.。

大学英语演讲globalwarming(一)
大学英语演讲globalwarming(一)Global Warming: Threats and SolutionsLadies and gentlemen, today I want to talk to you about a topic that affects us all: global warming. As we all know, global warming refers to the increase in average global temperatures over time. While it may seem like a distant problem, the fact is that global warming affects us all, from the air we breathe to the water we drink and the food we eat. In my speech, I will discuss the threats posed by global warming, as well as some of the solutions we can implement to combat it.Firstly, let's talk about the threats. Perhaps the most pressing threat posed by global warming is the increase in extreme weather events. These include droughts, heatwaves, floods and hurricanes, all of which have become more frequent and severe in recent years. These events not only cause significant damage to property and infrastructure but pose a very real threat to human life. Additionally, global warming increases the risk of wildfires, which have also become more common and severe in many parts of the world.Another significant threat is the impact on ecosystems. As temperatures rise, ecosystems are becoming unbalanced,risking the extinction of thousands of species. This is due, in part, to changes in temperature, weather patterns, and ocean acidity levels, all of which are caused by globalwarming. These changes are disrupting the food chain, which can have devastating long-term effects on many species.Now, let's focus on the solutions. There are several ways we can combat global warming. One of the most effective approaches is to reduce our reliance on fossil fuels. This can be achieved by increasing the use of renewable energy sources such as solar, wind, and hydropower. By doing this, we can reduce our carbon emissions, which are one of the main contributors to global warming.Another way to combat global warming is to promote sustainable lifestyles. This means reducing waste, conserving energy, and adopting environmentally friendly habits. Governments can play a crucial role in promoting sustainable lifestyles by investing in public transportation and encouraging sustainability in businesses.Finally, it's also important to raise awareness of global warming and its consequences. By educating ourselves and others, we can inspire change and motivate people to take action to help protect our planet.In conclusion, global warming is a serious threat thataffects us all. It poses significant risks to our health, our environment, and our economies. However, we can take action to combat it. By reducing our reliance on fossil fuels, adopting sustainable lifestyles, and raising awareness, we can help protect our planet and ensure a better future for generations to come. Thank you.。
The Urgent Challenge of Global Warming全球变暖中英文演讲稿
The Urgent Challenge of Global WarmingLadies and Gentlemen：Today, I stand before you to discuss a topic that is neither new nor unfamiliar, yet it demands our utmost attention: Global Warming.Global Warming, a phenomenon caused primarily by anthropogenic emissions of greenhouse gases, is altering the very climate that sustains life on Earth. It is not a distant threat but a present reality, manifesting in rising sea levels, extreme weather events, and the melting of polar ice caps.The scientific consensus is clear: we are facing a climate crisis. The Intergovernmental Panel on Climate Change (IPCC) has repeatedly warned that without drastic reductions in greenhouse gas emissions, we are heading towards a future marked by catastrophic climate change.The impacts of global warming are already being felt across the globe. We see it in the increased frequency and intensity of hurricanes, wildfires, and droughts. We see it in the displacement of communities due to rising seas and the devastation wrought by flooding. And we see it in the declining health of our oceans, which are absorbing much of the excess heat and carbon dioxide we are pumping into the atmosphere.But Global Warming is not just an environmental issue; it is a social, economic, and political challenge. It threatens food security, access to clean water, and the very livelihoods of millions of people around the world. It exacerbates global inequalities, as those who contribute least to the problem are often the first to suffer its consequences.The solution to global warming lies in our hands. We must transition to renewable energy sources, reduce our reliance on fossil fuels, and adopt sustainablepractices in all aspects of our lives. Governments must lead the way by enacting policies that prioritize climate action and encourage green investments. Businesses must innovate and adopt sustainable practices that prioritize long-term environmental health over short-term profits. And individuals must take responsibility for their actions, reducing their carbon footprint and demanding change from those in power.Ladies and Gentlemen, the time for action is now. The cost of inaction is far greater than the cost of taking bold and decisive steps to address global warming. Future generations are counting on us to rise to this challenge and leave them a planet that is healthy, habitable, and just. Let us not fail them. Thank you.全球变暖女士们，先生们：，今天，我站在你们面前讨论一个既不新鲜也不陌生的话题，但它需要我们最大的关注：全球变暖。

He was informed of his life in the death of the ultimatum had been issued - and three months would be shot, so he does not pin any hope on the survival of the. Two weeks later, he calmed down. He visited every day to face the smiling general, the generals began to ignore him, then, he has a little goodwill, and began to talk to him ... ... three months after the date on the blink of an eye later, shot By the time this is a very strange shot: General cite shot on the left hand, right hand to give back to the team that can be a continuation of the war. His turn, he closed his eyes, waiting for death to come, this time, his generals to see, he slowly raised his right hand ... ...This is the life-saving force, which is hard to imagine the magic! Every day to a general apology to smile, even from its own bottom line back to the original point of death, this not the great power of a smile?If we are able to smile in the face of every person and every thing, the success or failure of honor in the face with a smile, a smile in the face of all with a smile of genuine spiritual insights better life, it would be very happy and well-being.Jan-mouth, will be able to draw a beautiful arc, which is howsimple things!

First they extend greetings to their parents. Then each child will get money as a New Year gift, wrapped up in red paper.

And the abilities of those animals have been collected to it. Wang Chong, once pointed that the horn of dragon liked deer's one, the head liked camel's one, the eyes liked rabbit's one, the neck liked snake's one, the talon liked eagle's one, the palm liked tiger's one and the ear liked cattle's one.全球变暖英语演讲稿篇4Dear leaders and teachers:Good morning!"Youth" in the history of the history of the Han Dynasty, the original intention of the spring, that is, the beginning of a year.

Ladies and gentleman:
Welcome to attend our international academic conference on global warming. I would like to express my thanks to you for your attendance.
As we know, our earth is having a fever. The consequences of global warming suggest that reducing global warming is not an easy affair.
First of all, citizens do not believe that global warming is a big deal. On one hand, citizens pay more attention to their personal affairs. They prefer to focus on their jobs and family life rather than global warming issues. In other word, people do not realize that it is their duty to deal with global warming. On the other hand, there is no convincing evidence showing that global warming will have harmful impact. For example, the seaport cities are still safe and prosperous now. The climate of the earth does not extremely change. The food supplies keep growing and the agriculture of the coastal area is still productive. So the residents of the seaport cities still feel easy and comfortable. In a word, people do not concentrate on global warming.
Secondly, the desperate need of energy will be a big obstacle of reducing global warming. In order to develop our economy, we have to make use of energy such as the burning of coal, oil, and wood, causing the temperature rise. As we know, economy is so important to our life that it is impossible to stop using energy. What can we do? Governments has put forward a series of policies to encourage people to use clean energy such as wind energy, water energy, nuclear energy and geothermal energy. But the proportion of using clean energy is extremely small so far.
Thirdly, most of the countries are not willing to pay much money to deal with global warming. The rich countries hold the opinion that it is everyone’s responsibility to deal with global warming, while the poor ones do not agree. The developing countries considered that developed countries should take more responsibility since they product more gas emissions. Lawmakers from the Group of Eight (G8) nations, together with five major developing countries, said many governments are doing too little to support their speech. For instance, United States refused to ratify the Kyoto Protocol to cut greenhouse gas emissions.
In a word, it needs a lot of cooperation between experts to reducing global warming.
Finally, I wish every success at this conference. Thank you!。
