 温馨提示

1、你家乡的气候怎么样?你喜欢吗?为什么或者为什么不呢?

2、是否注意到你家乡或者你居住城市的气候在发生变化?那是什么样的气候呢?

3、你对温室效应有什么看法哈~?它会影响到地球升温吗?

 

文本

 

呼吸到的空气中有一种气体是我们生命的源泉。不幸的是,人类不能过多地拥有同一件好的东西,正如二氧化碳的增长已经到了使地球升温造成危害的极限。ISSC ASIMOV这里为我们介绍的所谓空气中的恶魔,诠释了它的运作以及它可能到来的结果。

 

 

 

谁是酿成空气污染的元凶

 

Isaac Asimov

 

 

 

1)     空气中的元凶就是二氧化碳。

2)     它似乎并不构成元凶。它不是那么有毒并且就凭它在空气中仅占0.034%所占的分量看---似乎不构成对我们的伤害。

3)     况且,空气中那么小分量的二氧化碳还是生命耐以生存的基础。植物吸收二氧化碳转换成自己的纤维,为所有动物生命(当然,包括人类)所需提供了基本的食物供给,在这个过程中释放出的氧气,也同样成为所有动物生命所需。

4)     不过这里所谓明显的无害确切地说也恰恰是我们最基本的气体:

5)     在所有人看来,在未来的千百年的历程中,海平面将以不断攀升的速度年复一年地缓慢上升。海水持续侵蚀,迫使那些居住在海岸线低洼的地区(那些拥有地球人口稠密较大面积地区的)人们向内陆延伸。

6)     偶尔,海水也会超出它现有的水平线200英尺以上,浪花飞溅到曼哈顿摩天大楼20层楼的玻璃窗上。佛罗里达将淹没在浪花之中,就好象英格兰岛、人口稠密的尼罗河、中国低洼地区、印度和俄国一样。

7)     不仅将淹没许多城市,而且将丧失全球许多农作物生产旺盛的地区。这将会导致社会结构在食物供给的流失、饥饿广泛蔓延的压力下崩溃。

8)     归根结底,所有这些都是二氧化碳所至。可究竟是怎么产生的呢?连锁反应又是什么?

9)     其实,起因是由于太阳光使空气(包括二氧化碳)中的各种气体相互转换造成的。阳光,照射着大气层的最顶端,沿顺时针运转使地球表面升温。夜里,地球受到热辐射的冷却后在空气中形成红外线。

10)     不管怎么说,肉眼看上去大气并不能象红外线辐射那么晶莹剔透,二氧化碳特别钟情于这类辐射。正因如此,假如大气中不存在二氧化碳,那么夜晚热量也将会散发得更少。假如没有气体中尚存的那么点儿分子,恐怕地球的温度将骤降,甚至寒冷刺骨。

11)     怀揣一份感恩的心,多亏二氧化碳时时让我们感受到温暖舒适,但是,日益浓缩的二氧化碳恰恰又是大气中的元凶。1958年,大气中的二氧化碳的含量是0.0316%。从那以后的每一年,浓度正在渐渐攀升,而今已经达到了0.0340%。估计2020年大气中的二氧化碳浓度将成倍增长。

12)     这就意味着,下个世纪,地球的平均温度将悄然升高。其后果是,北极冰盖将融化。

13)     迄今发现,差不多90%的冰川覆盖在巨大的南极冰盖上。如果有一天冰盖融化,海平面上升,结果显而易见。

14)     可值得深思的是,为什么大气中的二氧化碳浓度会持续加重?

15)     谁是酿成空气污染的元凶?首先,在起初的几个世纪中,作为能源燃料增长率迅猛升高的首先是煤、其次是油和天然气。碳作为饱含了这些能源的燃料,一度千百年安全地埋藏在地下,而今正燃烧成二氧化碳,以每天成吨的速度释放到大气中去。

16)    还有更糟的诗,地球森林面积正在减少,起初还很慢,最近两个世纪以来急速消失,截止目前,森林面积消失的速度已经达到了每分钟64英亩。

17)    无论用什么取代森林,---草地或农场或夷为平地---种植即便燃烧也不对大气产生二氧化碳的植物,最终都将是随着森林面积的消失,越来越少的植物可以从大气中吸走二氧化碳。

18)    但是,这也带给我们了一个新的观点。二氧化碳不是它自己产生的。是人类燃烧煤、油和气。是人类减少了森林资源。是人,也是造成空气污染的元凶。

19)    怎么办?

20)    首先,拯救我们的森林,然后重新种植。

21)    其次,我们必须拥有一种不含二氧化碳生产的新型的燃料。核电站是其中的一种,但是那好像太危险了,还有其它的选择。还有浪能、潮能、风能和地球内热。最主要的是,有一种直接使用的唯一能源。

22)    所有这些都需要时间、努力和资金。问题就在于,国家与国家之间都在耗尽更多的人力和物力去筹措那些可以摧毁人类自身的军事武器,不是吗?

3. Do you have any idea of the greenhouse effect? How does it affect the temperature on Earth?

 

Text

 

There is one gas present in the air we breathe that is essential to life. Unfortunately,one can have too much of a good thing and the growth in carbon dixide threatens to warmup out planet to a dangerous extent. Isaac Asimov introduces us to this villain in th atmosphere,explaining how it works and what can be done about it.

 

The Villain in the Atmosphere

 

Isaac Asimov

 

1)     The villain in the atmosphere is carbon dioxide.

2)     It does not seem to be a villain. It is not v ery poisonous and it is present in the atmosphere in so small a quantity---only 0.034 percent---that it does us no harm.

3)     What'smore, that small quantity of carbon dioxide in the air is essential to life. Plants absorb carbon dioxide and convert it into their own tissue,which serve as the basic food supply for all of animal life (including human beings, of course). In the process they liberate oxygen,which is also necessary for all animal life.

4)     But here is what this apparently harmless and certainly essential gas is doing to us:

5)     The sea level is rising very slowly from year to year. In all likelihood, it will continue to rise and do so at a greater rate in the course of the next hundred years. Where there are low-lying coastal areas(where a large fraction of the world's population lives) the water will advance steadily,forcing peopleto retreat inland.

6)     Eventually the sea will reach two hundred feet above its present level, and will be splashing against the windows along the twentieth floors of Manhattan's skyscrapers. Florida will disappear beneath the waves,as will much of the British Isles, the crowded Nile valley,and the low-lying areas of China, India and Russia.

7)     Not only will many cities be drowned,but much of the most productive farming areas of the world will be lost. As the food supply drops, starvation will be widespread and the structure of society may collapse under the pressure.

8)     And all because of carbin dioxide. But how does that come about?What is the connection?

9)     It begins with sunlight, to which the various gases of the atmosphere (including carbon dioxide) are transparent. Sunlight, striking the top of the atmosphere, travels right through miles of it to warm the Earth's surface. At night,the Earth cools by radiating heat into space in the form of infrared radiation.

10)     However, the atmosphere is not quite as transparent to infrared radiation as it is to visible light. Carbon dioxide in particular tends to block such radiation. Less heat is lost at night,for that reason,than would be lost if carben dioxide were not present in the atmosphere. Without the small quantity of that gas present,the Earth would be distinctly cooler,perhaps uncomfortably cool.

11)     We can be thankful that carbon dioxide is keeping us comfortably warm,but the concentration of carbon dioxide in the atmosphere is going up steadily and that is where the villainy comes in. In 1958,carbon dioxide made up only 0.0316 percent of the atmosphere. Each year since, the concentation has crept upward and it now stands at 0.0340 percent. It is estimated that by 2020 the concentration will be nearly twice what is now.

12)     This means that in the coming decades,Earth's average temperature will go up slightly. As a result, the pilar ice caps will begin to melt.

13)     Something like 90 percent of the ice in the world is to be found in the huge Antarctica ice cap, and another 8 percent is the Greenland ice cap. If these ice caps begin to melt,the sea level will rise,with the result that I have already described.

14) But why is the concentration of carbon dioxide in the atmosphere steadily rising?

15)     To blame are to factors. First of all, in the last few centuries,first coal,then oil and natural gas,have been burned for energy at a rapidly increasing rate. The carbon contained in these fuels,which has been safely buried underground for many millions of years, is now being burned to carbon dioxide and poured into the atmosphere at a rate of many tons per day.

16)    To make matters worse, Earth's forests have been disappearing,slowly at first, but in the last couple of centuries quite rapidly. RIght now it is disappearing at the rate of sixty---four acres per minute.

17)    Whatever replaces the forest---grassland or farms or scrub---produces plants that do not consume carbin dioxide being added to the atmosphere through burning of fuel,but as the forests disappear,less carbon dioxide is being removed from the atmosphere by plants.

18)    But this gives us a new perspective on the matter. The carbon dioxide is not rising by itself.It is people who are buring the coal,oil,and gas.It is people who are cutting down the forests.It is people, then,who are villains.

19)    What is to be done?

20)    First,we must save our forests, and even replant them.

21)    Second, we must have new sources of fuel that do not involve the production of carbon dioxide. Nuclear power is one of them, but if that is thought too dangerous,there are other alternatives. There is the energy of waves,tides,wind,and the Earth's interior heat. Most of all, there is the direct use of solar energy.

22)    All of this will take time,work, and money, to be true, but nations spread more time,work, and money in order to support competing military machines that can only destroy us all. Should we object to spending less time,work, and money in order to save us all?
