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.。

温室效应满分英语作文Here's a sample of an English essay on the greenhouse effect, written in an informal and conversational tone, with each paragraph maintaining its own distinct language characteristics:Oh, you know, the greenhouse effect is like that big blanket that's getting thicker and thicker around our planet. It's not a cozy blanket, though. It's making the Earth hotter and hotter.You know what's weird? We're actually the ones adding more layers to this blanket. All those cars, factories, and even our homes are pumping out gases that trap heat in the atmosphere. It's like we're cooking our own planet.I mean, look at the polar bears. Their homes are melting away because of this crazy warming. And the coral reefs? They're bleaching because the water is getting too hot. It's like nature is screaming, "Hey, guys, what'sgoing on?"But here's the good news: we can do something about it. We can start by using less fossil fuels and more renewable energy sources. You know, like solar panels on our roofs or electric cars. Every little bit helps.Plus, we can all make a difference in our daily lives. Turn off the lights when you leave a room, use reusable shopping bags, and plant a tree or two. It's the small steps that.。
温室效应演讲稿3分钟英文
温室效应演讲稿3分钟英文The greenhouse effect is a phenomenon that has been a topic of great concern in recent years. It refers to the process by which the Earth's atmosphere traps heat from the sun, leading to an increase in the planet's overall temperature. This is primarily caused by the release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide into the atmosphere, mainly as a result of human activities such as burning fossil fuels, deforestation, and industrial processes.The consequences of the greenhouse effect are far-reaching and have the potential to significantly impact our planet and all living organisms. One of the most immediate and visible effects is the rise in global temperatures, leading to changes in weather patterns, melting of polar ice caps, and rising sea levels. This can result in more frequent and severe natural disasters such as hurricanes, droughts, and floods, posing a threat to human lives and livelihoods.Furthermore, the greenhouse effect can also have detrimental effects on ecosystems and biodiversity. Changes in temperature and precipitation patterns can disrupt the natural habitats of many species, leading to a decline in their populations and even extinction. This can have cascading effects on entire food chains and ecosystems, ultimately affecting the balance of nature and the services it provides to human society.In addition to environmental impacts, the greenhouse effect also has significant social and economic implications. For example, changes in weather patterns can affect agricultural productivity, leading to food shortages and increased food prices. This can disproportionately affect vulnerable populations in developing countries who rely on agriculture for their livelihoods. Furthermore, the increasing frequency and severity of natural disasters can result in significant economic losses, as well as displacement and migration of affected populations.Addressing the greenhouse effect requires a multi-faceted approach that involves both individual and collective actions. At the individual level, we can reduce our carbon footprint by adopting sustainable practices such as using energy-efficient appliances,reducing waste, and choosing renewable energy sources. Additionally, advocating for policies that promote clean energy, sustainable land use, and emissions reductions at the local, national, and international levels is crucial for mitigating the greenhouse effect.Education and awareness-raising about the greenhouse effect and its impacts are also essential for fostering a sense of collective responsibility and inspiring action. By engaging in public discourse, supporting scientific research, and promoting environmental stewardship, we can work towards a more sustainable and resilient future for our planet.In conclusion, the greenhouse effect is a pressing issue that requires urgent attention and action. By understanding its causes and consequences, and by taking meaningful steps to reduce our impact on the environment, we can work towards mitigating its effects and creating a more sustainable future for generations to come. Thank you.。

This can be achieved through the implementation of sustainable practices, such as using renewable energy sources, improving energy efficiency, and promoting afforestation to absorb carbon dioxide. Additionally, raising awareness about the impact of the greenhouse effect and advocating for policy changes at both local and global levels are also essential in mitigating its adverse effects and protecting the environment for future generations.Translated content:温室效应是维持地球温度和支持生命的重要过程。
温室效应 英语作文
温室效应英语作文英文回答：The greenhouse effect is a phenomenon that warms the planet's surface by trapping heat in the atmosphere. It occurs when certain gases, known as greenhouse gases (GHGs), allow sunlight to pass through but absorb and emit some of the infrared radiation emitted from Earth's surface. This leads to a gradual increase in the temperature of the atmosphere and the planet as a whole.The primary greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (F-gases). These gases are released into the atmosphere through both natural processes and human activities. For instance, CO2 is released when fossil fuels are burned for energy, while CH4 is emitted from sources such as landfills and livestock.The greenhouse effect is a natural phenomenon that hasexisted for billions of years. It is responsible for maintaining the Earth's surface temperature at a habitable level. However, human activities have significantly increased the concentration of greenhouse gases in the atmosphere since the pre-industrial era. This has led to an enhanced greenhouse effect, resulting in global warming and climate change.The impacts of climate change are already being felt around the world. These include rising sea levels, more frequent and intense heat waves, droughts, floods, and wildfires. Climate change also poses risks to human health, such as heat-related illnesses, respiratory problems, and the spread of infectious diseases.To mitigate climate change and reduce the risks associated with it, it is essential to reduce greenhouse gas emissions. This can be achieved through a combination of measures, including transitioning to renewable energy sources, improving energy efficiency, reducing deforestation, and implementing sustainable land-use practices.中文回答：温室效应。
温室效应保护环境英语作文
温室效应保护环境英语作文The Greenhouse Effect and Our Responsibility to Protect the Environment.The greenhouse effect, a natural process that maintains the temperature of the Earth's atmosphere, has become a global concern due to human-induced emissions of greenhouse gases. These gases, primarily carbon dioxide, methane, and nitrogen oxides, trap heat in the atmosphere, leading to global warming and a range of associated environmental problems. It is crucial for us to understand the implications of the greenhouse effect and take action to mitigate its negative impacts on our planet.The greenhouse effect occurs when solar radiation reaches the Earth's surface, warming it. The warmed surface then emits infrared radiation, which is absorbed by greenhouse gases in the atmosphere. These gases then re-emit the radiation back towards the Earth, effectively trapping heat and keeping the planet warm. However, whenhuman activities increase the concentration of these gasesin the atmosphere, the greenhouse effect becomes exacerbated, leading to global warming.The impacts of global warming are already being felt across the globe. Rising temperatures have led to meltingice caps, sea level rise, and extreme weather events suchas floods, droughts, and hurricanes. These changes have had profound effects on ecosystems, human health, and the economy. For example, coral reefs are being destroyed by ocean acidification caused by increased carbon dioxide levels, and agricultural yields are being negatively impacted by changing climate patterns.In order to mitigate the negative impacts of the greenhouse effect, it is essential for us to take action. Firstly, we must reduce our emissions of greenhouse gases. This can be achieved through the adoption of renewable energy sources such as solar, wind, and hydroelectric power, as well as energy-efficient technologies and practices. Additionally, we must promote sustainable transportation systems that encourage walking, cycling, and publictransportation over private vehicles.Secondly, we must work to protect and restore our natural carbon sinks, such as forests and wetlands. These ecosystems play a crucial role in absorbing carbon dioxide from the atmosphere and storing it in biomass or soil. By protecting and enhancing these carbon sinks, we can help to offset our emissions and mitigate the greenhouse effect.Thirdly, we must promote awareness and education about the greenhouse effect and global warming. It is crucial for us to understand the science behind these issues and the implications for our planet. By educating ourselves and others, we can work towards creating a more environmentally conscious society that is committed to protecting our planet.In conclusion, the greenhouse effect is a complex issue that requires a multifaceted approach to address. We must take action to reduce our emissions, protect and restore our natural carbon sinks, and promote awareness and education about global warming. By doing so, we can help tomitigate the negative impacts of the greenhouse effect and protect the environment for future generations. It is our responsibility to ensure that our actions align with the needs of our planet and to create a more sustainable future for all.。
