具有讽刺意味的 “全球变暖”的特别研究
刊登日期：周一，2014年1月6日 01:26PM
在我看来，这艘载着科学家的俄罗斯船，在一片喧闹声中，深深陷进了南极的冰块中(时值南半球夏季)。而其后中国的破冰船也被困在了厚厚的冰层里。没有人多嘴提及，科学家们去那里儿的目的正是研究“全球变暖”。
一艘澳大利亚的破冰船不得不返回。中国的直升机将科学家们运往澳大利亚的破冰船上，因为中国的破冰船也被卡住了。现在似乎两艘船都在夏季的冰里搁浅了。美国海岸防卫队的破冰船正前往对他们进行救援。
啊，“全球变暖”真是表现到极致了。

Global warming is a concern 是个完整句子.

has become one of the most serious problem,drawing all people's attention

翻译成 仅仅
毫无疑问 全球变暖是有人类活动引起的 而不仅仅是随即发生的自然现象.

In recent years,global warming has resulted in a lot of environmenttal crisis.How to protect out environmental has become a hot issue all over the globe.Global warming has caused a great harm to the only planet we live on.The reasons for global warming,such as the destruction of forests,the release of carbon dioxide make our temperature getting higher and higher.We should take effective measures to prevent our environment from further pollution.Possible actions are as follows:planting trees and reducing the application of disposible commodities could effectively reduce the process of global warming.Renewable and recycleable products could lower the emission of carbon dioxide.It is global warming that does great harm to the environment,therefore,now it is urgent that we should strive to do our best and make it possible for citizens to do whatever they can to contribute to the prosperity of our environment.

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation.Global surface temperature increased 0.74 ± 0.18 °C between the start and the end of the 20th century.
全球变暖指的是在一段时间中,地球的大气和海洋温度上升的现象.在20世纪,全球平均接近地面的大气层温度上升了摄氏0.74度.
科学界发现过去50年可观察的气候改变的速度是过去100年的双倍,有理由认为该时期的气候改变是由人类活动所推动.

你的翻译的意思是错的.
1.Global warming awaits your participation to make a change.
2.做标语用：Stop global warming.Your participation counts.

全球变暖是一种趋势，即环境将更暖

什么是温室效应?有什么危害?
温室有两个特点：温度较室外高,不散热. 生活中我们可以见到的玻璃育花房和蔬菜大棚就是典型的温室.使用玻璃或透明塑料薄膜来做温室,是让太阳光能够直接照射进温室,加热室内空气,而玻璃或透明塑料薄膜又可以不让室内的热空气向外散发,使室内的温度保持高于外界的状态,以提供有利于植物快速生长的条件.
由环境污染引起的温室效应是指地球表面变热的现象.
它会带来以下列几种严重恶果：
1) 地球上的病虫害增加；
2) 海平面上升；
3) 气候反常,海洋风暴增多；
4) 土地干旱,沙漠化面积增大.
科学家预测：如果地球表面温度的升高按现在的速度继续发展,到2050年全球温度将上升2－4摄氏度,南北极地冰山将大幅度融化,导致海平面大大上升,一些岛屿国家和沿海城市将淹于水中,其中包括几个著名的国际大城市：纽约,上海,东京和悉尼.
温室效应是怎么来的?我们能做什么?
温室效应主要是由于现代化工业社会过多燃烧煤炭、石油和天然气,这些燃料燃烧后放出大量的二氧化碳气体进入大气造成的.
二氧化碳气体具有吸热和隔热的功能.它在大气中增多的结果是形成一种无形的玻璃罩,使太阳辐射到地球上的热量无法向外层空间发散,其结果是地球表面变热起来.因此,二氧化碳也被称为温室气体.
人类活动和大自然还排放其他温室气体,它们是：氯氟烃（CFC〕、甲烷、低空臭氧、和氮氧化物气体、地球上可以吸收大量二氧化碳的是海洋中的浮游生物和陆地上的森林,尤其是热带雨林.
为减少大气中过多的二氧化碳,一方面需要人们尽量节约用电（因为发电烧煤〕,少开汽车.另一方面保护好森林和海洋,比如不乱砍滥伐森林,不让海洋受到污染以保护浮游生物的生存.我们还可以通过植树造林,减少使用一次性方便木筷,节约纸张（造纸用木材〕,不践踏草坪等等行动来保护绿色植物,使它们多吸收二氧化碳来帮助减缓温室效应.

What is the greenhouse effect? What harm?
Two characteristics: greenhouse temperature is high, no heat, outdoor. We can meet in life of glass (a greenhouse and vegetable is typical of greenhouse. Use transparent glass or plastic greenhouse, is to allow sunlight to direct illuminate, heating indoor air into the greenhouse, transparent glass or plastic film and can not make indoor air outside sends out, make indoor temperature remains above the state, in order to provide outside for plant growth conditions.
The environmental pollution caused by greenhouse refers to the heat of the earth's surface.
It will bring to the following several serious consequences:
1) on the earth; the pest
2) rising seas,
3) ocean storms abnormal weather, increase,
4) land desertification and drought is increasing.
Scientists predict: if the earth's surface temperature at its present rate, by 2050 to continue the development of global temperatures will rise by 2-4 degrees Celsius, south polar ice melts in rising greatly, will rise greatly, some islands and coastal cities will be flooded in water, including several famous international cities: New York, Shanghai, Tokyo and Sydney.
What is the greenhouse effect? What can we do?
The greenhouse effect is mainly due to the modern industrial society overmuch burning coal, oil and gas, the fuel burning after release large amounts of carbon dioxide into the atmosphere.
Carbon dioxide gas, heat insulation and heat with the function. It is in the atmosphere is formed a kind of aeriform glass, make the sun radiate to heat the earth can spread from outer space, the result is the earth's surface heat up. Therefore, also called the greenhouse gas carbon dioxide.
Human activities and nature also emissions of greenhouse gases and other, they are: LvFuTing (CFC), methane, low nitrogen gas, ozone and on earth can absorb carbon dioxide is a Marine plankton and continental forests, especially tropical rainforest.
To reduce the atmosphere of carbon dioxide, on the one hand, need much people try to save electricity (because power, less coal burning car. On the other hand to protect forests and sea, for instance, don't let not overcutting forest to protect Marine pollution of plankton. We can also through afforestation, reduce the use of disposable wooden chopsticks, convenient save paper, wood pulp (with no trample on the lawn, action to protect the green plant, make them more carbon dioxide to help alleviate the greenhouse effect.

The Power of Nature (2/2)
Man’s power to create or destroy is nothing compared with nature’s
April 17,2007
Tornadoes
These spinning clouds of dust and debris have wind speeds reaching 300 mph.tornadoes can flatten buildings as well as pick up cars and houses and toss them around like toys.Most tornadoes occur in the Midwestern United States.Everything in the path of a tornado is destroyed,yet areas nearby can be left untouched.On a single day in 1999,around 1,500 people were either killed or injured from tornadoes in Tornado Alley.
Earthquakes
People can do nothing to prevent or stop an earthquake.When the earth shakes,whole buildings can collapse,killing people and destroying property.A powerful earthquake shook Pakistan in October 2005,killing more than 73,000 people.Earthquakes can also cause tsunamis,which devastate coastal regions.
Volcanoes
The lava,steam and ash from volcanoes change the landscape and climate.In 1815,Mt.Tambora in Indonesia erupted,killing 92,000 people.The ash from the volcano affected the climate around the world,making it noticeably cooler.In the Northern Hemisphere,the climate change resulted in the worst food shortage of the century.Lava flows destroy property,but because they move very slowly at first,they rarely kill humans.
There is nothing that can compare to nature’s power!

Secrets to a Healthy Life
1.Sufficient qi and blood as well as dredged meridians including veins and metabolism system are two indispensable elements of health.
2.No medicines can heal patients ultimately wether the medicine belongs to traditional Chinese medical science or the Western medicine.All illness are caused by a wrong with something.For this reason,if the patient want to be healthy again,he or she need first to get rid of the bad causing.Essentially,the healthy people are bond to have helthy mind.All kinds of philosophy or theory come from your heart.So long as your heart is plain,your body is healthy.According to this opinion,you need not hurry to the doctors but rely on your own restoration system to heal yourself.Actually,mankind are the same as animals to the extend of fixing themselves when get illed.
3.Right concepts are more helpful than expensive medicine or dangerous surgery.Motiviting by the right concepts,you can make correct desions; then comes the suitable behavior so that you can avoid many disasters.

What is Global Warming?
Global warming refers solely to the fact that the Earth's atmosphere is
warming near its surface.Simply put,it's getting hotter.The term does
not imply a cause or speak to cause.The scientific community believes
climate changes like global warming have occurred throughout Earth's
history and will continue to occur in the future.Some evidence links
global warming to solar activity; however,there are other theories as
well.
One popular theory relates to the "greenhouse effect." Gases that make up
our atmosphere are analogous to a greenhouse in that they allow sunlight
to pass through,then trap much of the heat from escaping.This naturally
occurring phenomenon keeps Earth's surface warmer than it would be
otherwise.However,human produced compounds regularly released into the
atmosphere in recent years have "thickened the greenhouse wall" beyond
naturally occurring levels.When this happens,even less heat escapes,
causing temperature to rise.This is called greenhouse warming and
results in global warming.
While the scientific community accepts global warming as a given,
greenhouse warming is more controversial.Everyone agrees that
human-produced compounds like carbon dioxide,methane,
chlorofluorocarbons (CFC's),etc.are being released into the atmosphere,
yet some argue it's not clear how this factors into the changes in global
warming.
Another distinct issue commonly associated with greenhouse warming and
global warming is the ozone.Ozone is a naturally occurring gas in the
lower atmosphere that helps trap heat.The burning of fossil fuels
creates even more ozone,as ozone is one component of smog.As ozone
builds,so does trapped heat,increasing the greenhouse effect.
Additionally,ozone plays a role in the upper atmosphere where it shields
the Earth from deadly ultraviolet (UV) radiation.Unfortunately,CFC's -
the same human produced compound that acts like a greenhouse gas in the
lower atmosphere - destroy ozone.This can result in holes in our upper
ozone layer as seen over Antarctica where cold temperatures,atmospheric
circulation and other factors combine to 'draw' these ozone holes.
In conclusion,global warming and the issues surrounding it have
far-reaching implications and can significantly impact human life on many
levels.For this reason,scientists want to know how long the Earth has
been warming,at what rate is it warming,and what factors are causing
it.These answers will better prepare us to handle the effects of global
warming.

别跪求了 初一就会搞这个 以后咋办呢?估计你们老师也会百度吧 被他发现你就完了 我是大四 不适合写初一的文章 见谅

El Nino(厄尔尼诺)现象又称El Nino海流,是太平洋赤道带大范围内海洋和大气相互作用后失去平衡而产生的一种气候现象,就是沃克环流圈东移造成的.正常情况下,热带太平洋区域的季风洋流是从美洲走向亚洲,使太平洋表面保持温暖,给印尼周围带来热带降雨.但这种模式每2—7年被打乱一次,使风向和洋流发生逆转,太平洋表层的热流就转而向东走向美洲,随之便带走了热带降雨,出现所谓的“El Nino现象”.
La Nina(拉尼娜)是指赤道太平洋东部和中部海面温度持续异常偏冷的现象（与El Nino现象正好相反）.是气象和海洋界使用的一个新名词.意为“小女孩”,正好与意为“圣婴”的El Nino相反,也称为“反El Nino”或“冷事件”.El Nino和La Nina是赤道中、东太平洋海温冷暖交替变化的异常表现,这种海温的冷暖变化过程构成一种循环,在El Nino之后接着发生La Nina并非稀罕之事.同样La Nina后也会接着发生El Nino.但从1950年以来的记录来看,El Nino发生频率要高于La Nina.La Nina现象在当前全球气候变暖背景下频率趋缓,强度趋于变弱.
global warming(全球气候)变暖是一种“自然现象”.由于人们焚烧化石矿物以生成能量或砍伐森林并将其焚烧时产生的二氧化碳等多种温室气体,由于这些温室气体对来自太阳辐射的可见光具有高度的透过性,而对地球反射出来的长波辐射具有高度的吸收性,也就是常说的“温室效应”,导致全球气候变暖.近100多年来,全球平均气温经历了冷－暖－冷－暖两次波动,总的看为上升趋势.进入八十年代后,全球气温明显上升.global warming的后果,会使全球降水量重新分配,冰川和冻土消融,海平面上升等,既危害自然生态系统的平衡,更威胁人类的食物供应和居住环境.

往这里看看

Global warming is a concern 是个完整句子.

这是一个强调句
It is global warming(,rather than other factors,)that has led to the extreme weather.
这样看就很清晰了 rather than other factors作为插入语 混淆我们的视线和判断
去掉后
It is global warming that has led to the extreme weather.
就是典型的it is...that...的强调句型了
知道这些后 自然就不会误用which了.
不知LZ是否满意?

Global warming is the increase in the average temperature of the Earth's near-surface air and the oceans since the mid-twentieth century and its projected continuation.Global warming is caused by several factors:carbon dioxide from power plants,carbon dioxide emitted from cars,carbon dioxide from heating systems,and deforestation.
Carbon dioxide is emitted from burning fossil fuels for the purpose of electricity generation.Coal accounts for 93% of the emissions from the electricity utility industry.The released carbon dioxide contributes to the increase of green house gas and causes the temperature raise.Carbon dioxide is also produced from the heating systems in buildings and houses from natural gas furnaces and coal-fired generation.Aside from the burning of gasoline,deforestation also contributes to global warming.Cutting down tropical forests will cause more carbon dioxide in the air because the temperate forests of the world absorbs 2 billion tons of carbon each year.

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,causingthe sea level to rise and many natural disastersto 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.

1全球变暖会使那些居住在北极地区的动物们面临危机吗?
2那是"北极故事"提出的问题.

Most of us are worried about global warming.It’s a problem that will change the future of the world we live in and affect generations to come.
People around the world may feel that the climate has been getting steadily warmer and warmer in recent years.Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters.Drought lasts longer in some dry areas.People find that without air conditioners they could hardly work or fall asleep on hotter summer daysg.
The side effects of global warming are alarminS.A warmer global climate melts the ice caps,raising sea levels.What is more,it disturbs weather patterns,causing droughts,severe storms,hurricanes (飓风).People suffer a lot from disasters relevant to global warming.
To stop global warming we should make immediate and continual efforts.We hope the situation will soon change.Global warming catches and holds our concern,for it affects us and will affect our later generations.We cannot wait any longer.Do it.Do it right.Do it right now.
