There is little doubt that the planet is warming.

Over the last century, the planets temperature has risen by around 1 degree fahrenheit ( 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 someof 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

Whenyou 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 homesalso 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 CO2each 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.

篇二：英语演讲环境温室效应

The Greenhouse Effect

全球气候变暖，是到目前为止对地球和人类生存最为紧

迫也最为严重的威胁因素之一。Global warming is one of

the most urgent and the most serious factors now threaten Earth and human's survival

最近，全世界冰川融化速度创下历史最快纪录，从安第斯山脉到北极，冰川消融速度加快。全球气候变暖将直接导致南、北极以及其

它冰川融化，同时一些雪山也将随着气温的不断升高而消失。而融化

后的冰川，将使海平面快速上升，世界很多美丽的城市终将被海水所

淹没。

Recently, The speed of melting glaciers set the record for the fastest, from the Andes to the Arctic glaciers melting faster. Global warming will lead directly to melting of the Antarctic, the Arctic and other glaciers, Meanwhile, some snow-capped mountains will disappear with temperatures rise. The glaciers melted will enable the sea level to rise rapidly, many beautiful cities in the world will eventually be submerged.

100年后南极只曾留下回忆

100 years later, the Antarctic had left only memories气温升高，全球变暖，极地冰川融化，企鹅失去家园！

Higher temperatures makes global warming and Melting of polar ice, so the penguins lose their homes!

30年后的夏季，北极可能是一片汪洋

Summer after 30 years, the Arctic may be an ocean.

乞力马扎罗山的“雪帽”将在15年内被摘掉

Kilimanjaro "snow cap" will be taken off in 15 years.

乞力马扎罗山是非洲最高的山脉，它距离赤道仅仅300

多公里，顶部却终年满布冰雪。但是，全球变暖导致这座山的终年积雪不断消融，专家预言，“雪帽”将在15年内被

摘掉。

Kilimanjaro is the highest mountain in Africa, it

is just over 300 km from the equator, but the top covered with snow all year round. However, Global warming leads to the mountain snow continue to melt, experts predict,

"snow cap" will be taken off in 15 years.

什么造成了温室效应

What causes the greenhouse effect

我认为主要有两个原因：人类排放二氧化碳和砍伐树木

I think there are two main reasons: humanemissions of carbon dioxide and cuts down trees.

人类每秒钟释放的二氧化碳已经超过700吨，一年就是

230 亿吨Carbon dioxide released by humans every second has more than 700 tons ,a year is 23 billion tons.

亚马孙河流域的农民正在焚烧热带雨林，以开垦更多耕地。每分钟，全世界清除掉的热带森林的面积，相当于200

个足球场的大小。依照

现在的这种破坏速度，亚马孙雨林将在400年以内完全

消失。

Amazonian farmers are burning rainforest to reclaim more land. Every minute, The world's tropical forests cleared an area equivalent to the size of 200 football fields . According to the current rate of this destruction , The Amazon rainforest will xxpletely disappear within 400 years.

我们依靠在地球上的一切，我们需要生存，所以让我们

照顾它。We rely on the Earth for everything, we need to survive, so let ' s take care of it.

篇二：以全球变暖问主题的演讲稿

global 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 xxes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases xxposed
