  全球变暖英语作文 篇1

  When global warming, the world have changed dramatically.

  The Antarctic ice and snow melt, human feeling will be under water, it is human to take the consequences. Arctic overlord, the polar bear also gradually extinction due to global warming. Has been the mother to a pair of scissors to bear, baby bear curiously ask: "mother, with scissors stem what ah?" Mom replied in a tone of command: "quick shearing, longer so thick hair will be hot dead!" Naive to bear looked at his mom, "we live in the ice and snow, how can heat? This is our coat, without it will be cold, can't cut!" Mother bear tone with a sad and sigh: "global warming, in does not adapt, now I'm afraid go!"

  Global warming, the polar bear can't find food, even little bear, it is be compelled helpless! Humans shall make profound reflection to your behavior, but, when global warming, human couldn't realize his mistake! Only know no longer suffer from the cold in winter, the temperature rose, the cold has gone, only the immediate interests, didn't know that will be far away from the white snow, originally should be open the flowers in the winter.

  When global warming, I hope this to human consciousness already consequences. Early up, to stop all this happen!

  当全球气候变暖时,世界发生了巨变。

  南极,冰雪融化,人类感觉将要处于冰水之中,这是人类自食其果。北极的霸主北极熊,也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀,熊宝宝好奇地问:“妈妈,用剪刀干什么呀?”妈妈以命令的语气回答:“快剪毛,再长这么厚的毛会被热死的!”小熊天真的望着妈妈:“我们住在冰天雪地里,怎么会热呢?这是我们的外衣,没有它会受冻的,不能剪!”熊妈妈的语气中带点悲伤和叹息:“现在全球变暖,在不适应,恐怕就走向灭亡了!”

  全球变暖,北极熊无法找到食物,甚至食用小熊,这是被逼无奈呀!人类应当对自己的行为进行深刻的反省,可是,当全球变暖时,人类还无法意识到自己的`错误!只知道冬天不再受寒风的折磨,温度上升了,寒冷已离去,只顾着眼前利益,可不知道以后将远离那洁白的雪,原本应在寒冬中开放的花。

  当全球变暖时,希望人类早已意识这以后果。趁早弥补,阻止这一切的发生!

  全球变暖英语作文 篇2

  At present, the gravity of the situation of global warming. This is not only related to atmospheric pollution, there is a certain relationship with the sun.

  Solar system is like a boundless cobwebs, but the sun is in the middle position, the earth will spread around the sun (from a distance is very close to the earth and the sun is, far, far away, but the actual distance of unimaginable). The earth moves around the sun, like a big ball on a large online, with a small steel ball on quality be sunken place big iron ball pressure, then you will find that the quality of small iron turn the club around the big iron ball, far from the big iron ball, and turned slowly, later you will find that the small ball go faster and faster, is getting closer and closer to the big iron ball, will eventually collided with the big iron ball.

  According to the findings, you may have found the cause of global warming. The sun is like a big ball is located in the center of network, motionless, and the earth like a small ball moves around the sun. Because the distance between the sun and the earth are too big, so a long time to collide with the sun. And now the earth slowly close to the sun (said to be close to, in fact is a long way) so say, the cause of global warming, does not rule out the ah.

  This is just a guess. I think, however, do not rule out this reason, who knows the earth what will happen in the future.

  Looking forward to...

  目前,全球变暖事态严重。这不仅跟大气污染有关,很有可能跟太阳运动存在着某种关系。

  太阳系就像一张无边无际的蜘蛛网,而太阳就位于中间位置,地球就散布在太阳旁边(从远处看地球和太阳是很近,但实际很远很远,远的难以想象)。地球是围绕太阳转的,好比把一个大铁球放在一张大网上,在拿一个质量小的铁球放在被大铁球压凹的地方,这时你会发现,质量小的`铁球会围绕大铁球转,先是离大铁球远,而且转的速度很慢,过一会你会发现小铁球越转越快,离大铁球越来越近,最终会跟大铁球相撞。

  根据这个发现,你也许会知道全球变暖的原因了。太阳就像大铁球位于网中心,一动不动,而地球就像小铁球一样围绕太阳转。因为太阳和地球距离相差太大,所以要很长时间才和太阳相撞。而且现在地球慢慢接近太阳(说是接近,其实还很远呐)所以说啊,地球变暖的原因,也不排除这个啊。

  这只是一种猜想。不过,我想也不排除这个原因,谁知道日后的地球会发生什么事呐。

  期待……

  With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike.

  So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by 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 the habit of saving energy in our daily life.

  No one,regardless of race, religion or nationality , can deny that the world we live in is becoming increasing intolerable because of the effects of global warming. According to many experts,even greater impact are still on the way.

  There are numerous cauuses for this problem. On one hand, human-related emission of carbon int the atmosphere is causeing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.

  It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautiful the environment . Besides, stricter laws concerning global warming and irrespngsible use of fuel resources have to be put into inffect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again.

  全球变暖英语作文 篇9

  When I went to school on Thursday morning, I found that the cars in the community were covered with a layer of white "gauyi" and it was snowing! But then again, I'm sad -- it's only mid-November, and because of global warming, it's starting to snow so soon. On the evening of the 19th, when I read the newspaper, I found a report about "natural gas shortage". Why would natural gas shortage be shortage? I opened the page with that question in mind.

  "Because of global warming, the weather turns cold quickly, and every household begins to use a lot of gas..." A line of small words under the title caught my eye. Global Warming again! I can't help but wonder why this "global warming" has so much power to make the weather turn cold, thunderstorms in winter and snowflakes in summer. My mother told me that the reason for global warming lies in human beings, we do not protect the environment, in summer, a large number of air conditioning, often drive private cars, produce a lot of exhaust gases, so that the earth's ozone layer is destroyed, the sun's radiation to the earth is more serious, the south and north polar glaciers are melting, the weather becomes cold. Ah! After all, it's still our fault, the selfless earth gave us all her resources, but we caused "global warming". Now can be good, the resources that nature gives us are in short supply, what should we do? In order to make up for our previous mistakes, we should save the resources that nature gives us, try not to use air conditioning, geothermal heating, air conditioning if you must use, also not higher than 20℃. We can't let the earth grieve any more.

  全球变暖英语作文 篇10

  The cold winter passed, but this winter did not even have a snow, the weather is not very cold, why is this?

  I asked my mother, mother said: "I don't know, you go to the Internet to check it." I turn on the computer and type -- why is global warming? Many answers appeared on the page.

  Because humans destroy forests and burn them to produce a variety of greenhouse gases, because these greenhouse gases from the solar radiation of visible light has a high transmittance, and the earth reflected with a high absorption, can strongly absorb the ground radiation in the infrared, is often said to be the "greenhouse effect". As a result of climate warming, global precipitation will be redistributed, glaciers and permafrost will melt, sea level will rise, and so on, endangering the balance of natural ecosystems, human food supply and living environment.

  Global warming not only endangers human beings, but also endangers the survival of animals. Take polar bears for example. Because of global warming, the glaciers are melting, and it is more difficult for polar bears to catch fish. Moreover, if the glaciers melt rapidly, the polar bears will eventually become extinct.

  To stop global warming, we should save every drop of water; Planting more trees to reduce desertification; Don't use disposable bags; Reduce carbon dioxide emissions. I appeal: for our homeland, let's act together!

  全球变暖英语作文 篇11

  As more and more countries become industrialized,global environment has been inevitably changed.And we are just experiencing the altered climate.Human activity is affecting global climate.Many scientists have predicated that global temperature will continue to rise in the foreseeable future because greenhouse gas emission is still increasing.

  Now there is a growing awareness that climate change is definitely not confined to a certain region or country.

  However,it is a problem all countries are involved.Most people would agree that as the planet warms and the sea ice is melting,polar bears are vulnerable to lose habitat,even

  threatening our home around the coastal areas.It is time we took measures to protect our environment.

  There is no denying that industrial emissions have been the dominant influence on climate change for the past 50

  years,overwhelming natural forces .To improve this situation, First of all, Ultimately, we,everyone on this blue planet are supposed to promote and carry out"low-carbon"lifestyle as an obligation.Secondly,carbon emission reduction must be put into implement,especially reducing fuel consumption and exhaust emissions,and it a wise choice for us to use renewable energy resources.Moreover,global climate summit are expected to play

  a significant part in urging involved powers to Carry out the state strategy of sustainable development so that our environment can be back to normal gradually.

  Greenhouse gas emission is but one of the many effects for the climate change.Another is excessive deforestation.And the Amazon tropic rain forest has seen man's greediness.Just imagine what would be like if our forest coverage rate were what it was 20 years ago?The answer is quite clear that global temperature would be lower and many species may not die out.Therefore,we must quit using disposable packaging and dishware and encourage of employment of

  environmentally-friendly materials.Besides,people ought to develop an awareness of environmental protection and cherish forests resources.Of course supporting recycling is also a good alternative way.

  In present case ,yet it could go a long way for us to recover our environment from climate change,we are obligated to

  dedicate ourselves to go for a harmonious planet.In addition,we have every reason to try our best to protect our environment.I believe the new environment is in store with our efforts.

  英语作文:

  In this report, I learned a lot of things, but my first thought is that the cause of global warming is carbon dioxide increases.

  Why is carbon dioxide will increase? I think the reason is that people often feed drive, raising livestock, factories discharge smoke... And so on. But these are all can be solved together, perhaps can improve the earth continued warming, for example: close to the destination can ride a bike, Destination is far away, you can use public transport; Livestock waste processed into Hanoi again; Factory can build a waste treatment plant... And so on.

  Please do not underestimate the power of carbon dioxide, wait until the sea level rise, urban flooding and flooded farmland, in the end would have faced the crisis of insufficient food. Please join me shout: "stop hurt the behavior of the earth! The earth on which we live is only one."

  中文翻译:

  在这一则报导中,我学到很多事,但我第一个想到的是,造成地球变暖的原因是二氧化碳增加。

  为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决,说不定可以改善地球继续暖化,例如:目的地很近的话可以骑自行车;目的地很远的话,可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。

  请大家不要小看二氧化碳的.威力,等到海平面上升、都市浸水和农地淹没,到最后就会面临粮食不足的危机了。请大家跟我一起喊:“停止伤害地球的行为吧!我们居住的地球只有一个。”

  The cold winter has passed, but this winter with snow is not, is not how cold the weather, why is this so?

  I asked my mother, my mother said: "I don't know, you go online to check." I opened the computer, input -- global warming. There have been many answers on the layout.

  Because of human destruction of forests and other greenhouse gases from the burning of when, because these greenhouse gases with high transmittance in the visible light radiation from the sun, and the earth is reflected is highly absorbent, can strongly absorb infrared radiation on the ground, the greenhouse effect is often said that the "". Global warming may lead to consequences, will lead to a global redistribution of precipitation, melting glaciers and permafrost, rising sea levels, damage the balance of the ecosystem and the human food supply and living environment.Global warming is not only harmful to humans, but also endanger the survival of animals. For example, the polar bear, because of global warming, melting glaciers and polar bear hunting fish more difficult, and the ice melting fast, this continues, sooner or later the polar bears extinct species like the polar bear, Arctic wolf, Arctic animals are penguins.

  Want to stop global warming, we should save every drop of water; plant more trees to reduce desertification; do not use disposable convenient bag; reduce the emission of carbon dioxide. I appeal to our homes, we act together now!

  全球变暖英语作文 篇14

  Many 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.

  很多人都认为是人类活动导致了全球气温上升。他们说全球变暖会对我们的环境造成可怕的后果,如干旱和洪水。

  What should governments do to help prevent global warming? Give reasons for your suggestions.

  政府该做什么来防止全球变暖呢?给出你建议的原因。

  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.

  地球的温度正在迅速改变。导致很多气候变迁,如热浪、干旱和洪水。科学家认为这是人类活动污染了地球的大气层的结果。如果政府不采取行动来防止全球变暖的话,这可能会成为灾难。他们可以在三个方面上有所行动;支持研究,制订法律和保持公众知情。

  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.

  首先,政府可以支持研究。例如,他们应该鼓励公司致力于汽车研发来减少污染。他们也应该支持来自风和水的电力替代能源,而不是来自石油和煤的电源。同时,他们应该主持会议来讨论温室气体排放的影响和可能解决问题的方案。

  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.

  其次,他们应该制定法律限制公司发出的温室气体。私人公司应该因为遵循这些法律而得到奖励。他们也应该因为创造出污染而受到惩罚。

  Finally, everybody is affected by global warming. Therefore, it is important 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.

  最后,每个人都是受到全球变暖的影响。因此,政府和个人在解决问题的.过程中是很重要的。例如,他们应该鼓励家庭尽可能多的节省能源,尽可能多的使用更高效的灯泡或少用热水。他们也应该鼓励公众回收,因为这对每个人来说都是必须的。另一种节约能源的方法是公共交通系统。政府应该把钱花在公共交通使公众尽可能容易的节约能源。

  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.

  总之,很明确的,各国政府可以做很多事情来防止全球变暖。他们应包括公司,支持科学家和鼓励个人保护地球。

  全球变暖英语作文 篇15

  我读完《全球气候》时,我才发现环境的严重污染。

  I read the "climate", I found that the serious pollution of the environment.

  里面说,现在由于二氧化碳的严重增多,导致全球变暖,从而影响海平面上升0.5厘米。听起来不算多,可是地球上还有更大的淡水区,那就是南极和格陵兰岛,如果南极的冰全部融化,海平面会上升60米,再加上格陵兰岛的冰,海平面还会上升6米。现在的.美国海边,经常有台风出现,导致巨大的经济损失,气候变暖使高山动物开始迁移,许多动物因为不适应环境而灭绝。

  It said, now due to carbon dioxide more serious, leading to global warming, sea level rise and influence 0. 5 cm. This may not sound very much, but the earth has more fresh water area, it is the Antarctic and Greenland, if all the melting of Antarctic ice, the sea level will rise 60 meters, plus the Greenland ice, sea level will rise 6 meters. Now America beach, often have typhoon occurs, resulting in huge economic losses, due to climate warming in Alpine animal migration began, many animal extinction because they do not adapt to the environment.

  所以我们要积极响应“保护环境,人人有责”的号召。

  So we should actively respond to "Protect environment is everyone's responsibility," the call.

  As is subtly revealed in the cartoons above, global warming is a real threat to our world. In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.

  The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world. To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress. China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy. With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising. In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms. Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surface temperatures due to global warming.

  Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world. Facing the growing menace of global warming, more scientific and active preventive measures should be taken on a larger scale to change for the better.

  正如上述漫画生动所示,全球变暖是当今世界的真正威胁。在图一中,由于全球变暖,极地冰川正在加剧融化。在图二中,一只无家可归的北极熊呆在一块孤立的大冰块上。

  这些漫画的目的是告诉我们:全球气候变暖对全世界的人们来说是迫在眉睫的威胁。首先,全球气候变暖会导致海平面的上升。由于气候变暖,中国大多数沿海地区都将随着海平面的上升逐渐消失,严重危害了国家的社会和经济发展。中国漫长的海岸线遍布着中国70%的大城市,人口数量占到全国总人口的一半以上,控制着国家经济的将近60%。这些城市的'社会、经济和文化发展程度相对先进,如果海平面继续保持上升的话,那么对于中国的内陆城市来说将会承受巨大的损失。其次,全球气候变暖加大了出现极端天气的可能性并加重其强烈程度,例如飓风、雪灾。在最近30年里,飓风和台风持续的时间越来越长,强度也越来越大。这是与全球气候变暖所带来的海平面温度上升紧密联系的。

  考虑到全球气候变暖带来的这些毁灭性影响,我们可以得出结论:全球气候变暖是全球的一大威胁。面临着日益增长的威胁,我们应该大规模采取更加积极、科学的预防性措施来促使其向更好的方向发展。

  全球变暖英语作文 篇17

  Earth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet.

  地球的温度开始太阳。大约百分之30的太阳光被反射回太空的光明面与云冰。在余下的百分之70,多数是由陆地和海洋吸收,其余的被大气层吸收。吸收太阳能加热我们的星球。

  As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane.

  当岩石,空气,和温暖的海洋,他们辐射热能源(热辐射)。从表面上看,这种能量进入大气层,大部分是由水蒸气和长寿命的温室气体如二氧化碳和甲烷的吸收。

  When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.

  当他们吸收辐射能量从地球表面,微观水或温室气体分子变成小加热器-就像在壁炉的'砖,他们散发热量,即使在火熄灭。他们在所有方向辐射。能量辐射回地球加热低层大气和表面,增强他们从阳光直射加热。

  This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.

  这种吸收和辐射热的气氛自然温室效应有利于地球上的生命。如果没有温室效应,地球表面的平均温度将是一个非常寒冷的18°C(0°F)而不是舒适的15°C(59°F),它是今天。
