acid rain
酸雨
According to a study published in the British scientific journal Nature,efforts to reduce the sulfate emissions that cause acid rain have also reduced other industrial emissions that help protect lakes from acid rain.根據(jù)一篇在英國(guó)科學(xué)期刊《自然》上刊登的研究報(bào)告指出，排放出的硫酸鹽是酸雨的污染源，在減少硫酸鹽排放量，確保湖泊不至受到酸雨傷害，同時(shí)也要求其他工業(yè)排放物也隨之減少。
AUV
自控水下艇
The cheapest way to explore the ocean floor,however,may be with the free-floating AUVs.
然而，海底探險(xiǎn)最經(jīng)濟(jì)的方法可能是使用自由漂浮形式的自控水下艇。

利用基因工程的技術(shù)，研究人員將這種植物原本用來(lái)儲(chǔ)存淀粉的器官轉(zhuǎn)而生產(chǎn)PHB，這是一種生物可遞降分解塑料。
Brent Spar
布蘭特史帕爾儲(chǔ)油平臺(tái)
And what about the Brent Spar campaign?Didn't your blunders at the time undermine the credibility of the Greenpeace organization?
那布蘭特史帕爾儲(chǔ)油平臺(tái)事件又如何？你們?cè)诋?dāng)時(shí)所犯的錯(cuò)誤是否損害了綠色和平組織的可信度？
Shell and the British government caved in.The tug reversed course and took the Brent Spar to a Norwegian fjord port to await a decision about its disposal.
殼牌公司和英國(guó)政府屈服了；拖船改變航向，將布蘭特史帕爾儲(chǔ)油平臺(tái)拖往挪威一峽灣的海港，等待后續(xù)的處置決定。
carbon offset
調(diào)整碳偏差
Electric utilities in Australia,the European Union and the U.S.,where carbon taxes have been under consideration,are especially interested in carbon-offset projects.
在澳大利亞、歐盟、及美國(guó)等計(jì)劃開征碳稅的地方，其境內(nèi)的電力事業(yè)機(jī)構(gòu)對(duì)于調(diào)整碳偏差計(jì)劃特別感興趣。
cesium 137
銫137
The wreck is already leaking cesium-137,a carcinogenic isotope.So far the leakage is considered too small to affect marine life or human health.
沉沒(méi)的潛艇正泄漏出銫137，這是一種致癌的同位素。目前泄漏量還很少，不致危及海洋生物及人類的健康。
chlorofluorocarbon
氟利昂制冷劑
The amount of ozone-eating chlorofluorocarbon in the atmosphere is dropping faster than anyone expected;the chemicals should peak around the year 2000,then decline.
在大氣中會(huì)侵蝕臭氧層的氟利昂制冷劑的含量，其降低的速度超出所有人的預(yù)期；這種化學(xué)物質(zhì)的量應(yīng)該在公元2000年達(dá)到高峰，之后才下降。
desertification
沙漠化
Most good agricultural land is already under plow,and each year desertification,improper irrigation and overuse take millions of acres out of production.
大部分良田目前都已經(jīng)被開墾，而每年的沙漠化、不當(dāng)?shù)墓喔纫约巴恋氐臑E用，使得數(shù)百萬(wàn)英畝的土地長(zhǎng)不出農(nóng)作物。
dioxin
戴奧辛
In 1985 the Environmental Protection Agency discovered that this procedure produces traces of dioxin,a highly toxic chemical,in waste water at the plants.
在1985年，環(huán)保署發(fā)現(xiàn)到這個(gè)過(guò)程會(huì)在工廠的廢水中產(chǎn)生微量的戴奧辛，這是一種毒性很強(qiáng)的化學(xué)物質(zhì)。
El Nino
厄爾尼諾現(xiàn)象
The El Nino that began last year and is now breaking up has been linked to record flooding in Latin America,the unseasonably warm winter in North America and the droughts in Africa.
去年開始的圣嬰現(xiàn)象，如今正漸漸衰退，有人認(rèn)為，拉丁美洲的大洪水、北美洲不合時(shí)序的暖冬，以及非洲的干旱，皆和該現(xiàn)象有關(guān)。
greenhouse effect
溫室效應(yīng)
Whether or not the new iceberg is a harbinger of the greenhouse effect,it is clearly a hazard for ships plying the southern seas,and so satellites and planes will keep a careful watch on it.
不論這座新冰山是否是溫室效應(yīng)的先兆，但很明顯，這座冰山對(duì)于往來(lái)于南方海域的船只是一大危險(xiǎn)，因此衛(wèi)星及飛機(jī)都密切觀察它的行蹤。
Greenpeace
綠色和平組織
Another reason for change is that Greenpeace has become a more complex organization.
綠色和平組織必須要改變的另外一個(gè)原因是，該組織的架構(gòu)已變得更龐雜。
ozone layer
臭氧層
Last week a team of researchers from Oregon State University offered a possible explanation:the thinning of the ozone layer.
上周，一隊(duì)來(lái)自俄勒岡州立大學(xué)的研究人員提供了一個(gè)可能的解釋：臭氧層愈來(lái)愈稀薄。
Data radioed from craft exploring Venus and Mars,have helped make us aware of the consequences of such potential man-made disasters as the greenhouse the destruction of the ozone layer,
從探測(cè)金星、火星的太空船傳回的資料，已有助于我們了解溫室效應(yīng)和臭氧層的破壞等潛在的人禍會(huì)造成的后果。
PCBs
聚氯聯(lián)苯
Normal operations of Army bases generate huge amounts of fuel spills,solvents and polychlorinated biphenyls(PCBs).
在陸軍基地所進(jìn)行的正常運(yùn)作會(huì)導(dǎo)致大量的油料溢出，并產(chǎn)生大量的溶劑與聚氯聯(lián)苯。
We live,environmentalists warn,in a world laced with dangerous chemicals,from powerful pesticides to toxic industrial wastes like dioxin and PCBs.
環(huán)保人士警告說(shuō)，我們居住的是個(gè)布有各種危險(xiǎn)化學(xué)物質(zhì)的世界，從強(qiáng)效殺蟲劑到戴奧辛、聚氯聯(lián)苯等有毒工業(yè)廢物都有。
Hot Times All Around
全面加溫
1.If good intentions and good ideas were all it took to save the deteriorating atmosphere,
如果光靠良好的用心與正確的觀念就能挽救逐步惡化中的大氣層，
the planet's fragile layer of air would be as good as fixed.
那么地球上這一層脆弱的空氣就沒(méi)問(wèn)題了。
The two great dangers threatening the blanket of gases that nurtures and protects life on earth-
這一層氣體，哺育著、庇護(hù)著地球上的生命，本身正面臨兩大威脅，現(xiàn)在已經(jīng)找出來(lái)了，
global warming and the thinning ozone layer-have been identified.
全球溫度上升，以及臭氧層損耗。
Better yet,scientists and policymarkers have come up with effective though expensive countermeasures.
不僅如此，科學(xué)家與決策人士還提出了盡管耕費(fèi)昂貴但是十分有效的防范措施。
2.But that doesn't mean these problems are anywhere close to being solved.
但是大氣層的問(wèn)題要獲得解決還早得很。
The stratospheric ozone layer,for example,is still getting thinner,
例如，在同溫層高處的臭氧層還是日漸稀薄，
despite the 1987 international agreement known as the Montreal Protocol,which calls for a phaseout of chlorofluorocarbons and other ozone depleting chemicals by the year 2006.
盡管在1987年國(guó)際間曾達(dá)成協(xié)定，呼吁逐步淘汰氟利昂制冷劑與其他破壞臭氧的化學(xué)物質(zhì)，以公元2006年為底線。
3.CFCs-first fingered as dangerous in the 1970s by Sherwood Rowland and Mario Molina,two of this year's Nobel-prizewinning chemists-
1970年代，羅蘭德與莫理納首度指出氟利昂制冷劑的危險(xiǎn)。
have been widely used for refrigeration and other purposes.
這種物質(zhì)普遍使用于冷凍以及其他用途。
If uncontrolled,the CFC assault on the ozone layer could increase the amount of hazardous solar ultraviolet light that reaches the earth's surface,
如果不加以控制，它會(huì)破壞臭氧層，造成陽(yáng)光中危險(xiǎn)的紫外線大量射到地球表面，
which would,among other things,damage crops and cause cancer in humans.
這會(huì)有許多害處，例如農(nóng)作物受損，也會(huì)致癌。
Thanks to a sense of urgency triggered by the 1985 detection of what has turned out to be an annual "hole" in the especially vulnerable ozone over Antarctica,the Montreal accords have suprred industry to replace CFCs with safer substances.
1985年發(fā)現(xiàn)，在南極洲上空特別脆弱的臭氧層出現(xiàn)破洞，世人終于感覺(jué)到事態(tài)緊急，于是達(dá)成《蒙特利爾公約》，促使各業(yè)以較安全的物質(zhì)代替氟利昂制冷劑。
4.Yet the CFCs already in the air are still doing their dirty work.
但是空氣中現(xiàn)有的氟利昂制冷劑還在繼續(xù)肆虐。
The Antarctic ozone hole is more severe this year than ever before,and ozone levels over temperate regions are dipping as well.
南極洲臭氧層破洞今年更趨嚴(yán)重，而且溫帶地區(qū)上空的臭氧含量也在下降。
If the CFC phaseout proceeds on schedule,the atmosphere should start repairing itself by the year 2000,say scientists.
科學(xué)家表示，如果淘汰氟利昂制冷劑能按照進(jìn)度達(dá)成，到2000年時(shí)大氣層應(yīng)能開始自我修復(fù)。
Nonetheless,observes British Antarctic Survey meteorologist Jonathan Shanklin:
然而英國(guó)南極觀測(cè)會(huì)的氣象學(xué)家尚克林表示：
"It will be the middle of the next century before things are back to where they were in the 1970s."
“要到下世紀(jì)中葉才能恢復(fù)到1970年的狀況。”
Even that timetable could be thrown off by international smugglers who have been bringing. illegal CFCs into industrial countries to use in repairing or recharging old appliances.
這個(gè)進(jìn)度恐怕也會(huì)出差錯(cuò)，因?yàn)閲?guó)際走私客一直挾帶非法的氟利昂制冷劑到工業(yè)國(guó)家，用以修補(bǔ)或添加在舊式用品中。
Last year alone 20000 tons of contraband CFCs entered the U.S.-mostly from India,where the compounds are less restricted.
去年一年就有2萬(wàn)噸違禁的氟利昂制冷劑進(jìn)入美國(guó)——大多來(lái)自管制較松的印度。
5.Developing countries were given more time to comply with the Montreal Protocol
發(fā)展中國(guó)家有較長(zhǎng)的期限來(lái)達(dá)到《蒙特利爾公約》的要求，
and were promised that they would receive $250 million from richer nations to pay for the CFC phaseout.
而且獲得承諾，可以得到富有國(guó)家提供的2.5億美元經(jīng)費(fèi)以逐步淘汰氟利昂制冷劑。
At the moment,though,only 60% of those funds has been forth coming.
可是目前這筆經(jīng)費(fèi)只有60%正在支付中。
Says Nelson Sabogal of the U.N.Environment Program:
聯(lián)合國(guó)環(huán)境規(guī)劃署的薩布果表示：
"If developed countries don't come up with the money,the ozone layer will not recuperate.This is a critical time."
“如果先進(jìn)國(guó)家的支票不能兌現(xiàn)，臭氧層就不能恢復(fù)。這是關(guān)鍵時(shí)刻。”
6.It is also a critical time for warding off potentially catastrophic climate change.
要想阻擋氣候形態(tài)轉(zhuǎn)變可能帶來(lái)的災(zāi)難，現(xiàn)在也是關(guān)鍵時(shí)刻。
Waste gases such as carbon dioxide,methane and the same CFCs that wreck the ozone layer all tend to trap sunlight and warm the earth.
各種廢氣，像二氧化碳、甲烷以及破壞臭氧層的氟利昂制冷劑，都可能捕捉陽(yáng)光，提高地球上的溫度。
The predicted results:an eventual melting of polar ice caps,rises in sealevels and shifts in climate petterns.
預(yù)期的結(jié)果：南北極冰帽終將溶化，海平面上升、氣候形態(tài)轉(zhuǎn)變。
7.Delegates to the 1992 Earth Summit in Rio passed a resolution urging industrial countries to reduce emissions of "greenhouse gases" to 1990 levels,
1992年里約熱內(nèi)盧地球高級(jí)會(huì)議的與會(huì)代表通過(guò)決議，呼吁工業(yè)發(fā)達(dá)國(guó)家將“溫室氣體”的排放量降低到1990年的水平，
mostly by increasing energy efficiency,but the agreement was purely voluntary-and exempted developing nations.
主要靠提高能源效率來(lái)達(dá)成，可是這項(xiàng)決議純屬自愿性質(zhì)——而且發(fā)展中國(guó)家也不包括在內(nèi)。
The industrial countries were also asked to help developing nations switch to less polluting technology in a program known as "joint implementation."
同時(shí)還敦促工業(yè)國(guó)家參與“聯(lián)合施行”計(jì)劃，幫助發(fā)展中國(guó)家轉(zhuǎn)移到低污染的技術(shù)狀態(tài)。
Unfortunately,that would take money,and industrial nations are not in a spending mood these days.
可是這樣做要花錢，而工業(yè)發(fā)達(dá)國(guó)家目前并沒(méi)有興致要花錢。
A few pilot projects have gone forward.
有幾項(xiàng)先導(dǎo)計(jì)劃是已經(jīng)展開了。
Three U.S. utilities are building a gas-fired power plant in the Czech Republic to replace a coalburning plant,
美國(guó)有3家公用事業(yè)公司正在捷克共和國(guó)興建天然氣發(fā)電廠以取代燃煤發(fā)電廠，
and Japan is exploring similar ventures in China.
日本也在貴國(guó)研究作類似的投資。
For the most part,though,getting developed countries to sponsor such programs has proved difficult.
但是一般說(shuō)來(lái)，要叫先進(jìn)國(guó)家出資來(lái)做這種計(jì)劃并不容易。
Inside the industrial world,emission-reduction efforts have been most successful in ecology-minded Germany and Japan.
在工業(yè)發(fā)達(dá)國(guó)家之林，有生態(tài)意識(shí)的德國(guó)與日本對(duì)于減低廢氣排放做得最有成效。
But in the U.S.,the world's biggest greenhouse polluter,legislators want to cut taxes rather than boost spending.
可是，在美國(guó)這個(gè)世界第一的溫室氣體污染國(guó)，議員一心想減稅，不想增加支出。
8.Until recently,laggard government could point to scientific uncertainty about whether global warming has started.
不久以前，沒(méi)有積極配合的國(guó)家還有一個(gè)借口：科學(xué)界還不確定全球溫度上升是否已經(jīng)開始了。
but that excuse is wearing thin.
這個(gè)借口現(xiàn)在快站不住腳了。
A draft report circulating on the Internet has proclaimed for the first time that warming has indeed begun.
國(guó)際互聯(lián)網(wǎng)上流傳的一份報(bào)告草案首度宣稱溫度確已上升。
Global average temperatures have risen about 1℃ in the past century,
全球平均溫度100年來(lái)上升了1℃左右，
and human activity is almost certainly part of the cause.
幾乎可以肯定部分原因是人類活動(dòng)造成的。
"It's as clear a record as we can possibly get of a warming trend,"says Tom Wigley,
湯姆•維格萊說(shuō)：“溫度上升的趨向，這是最明確的紀(jì)錄。”
a senior scientist with the U.S. National Center for Atmospheric Research
他是美國(guó)國(guó)家大氣研究中心的資深科學(xué)家，
and a contributor to the U.N.-sponsored Intergovernmental Panel on Climate Change(IPCC),which produced the report.
也是聯(lián)合國(guó)主辦的氣象變化跨國(guó)會(huì)議的成員。這份報(bào)告就是IPCC提出的。
9.The draft report says temperatures will probably continue to rise,jumping as much as 5℃ over the next century.
報(bào)告草案中表明氣溫可能會(huì)持續(xù)上升，到下一世紀(jì)末可以大幅升高5℃。
That will be the biggest increase since the warming that ended the last Ice Age-
自從上一次冰河時(shí)代結(jié)束以來(lái)，這算是最大規(guī)模的溫度上升，
but this one will be taking place over decades,not centuries.
而且僅歷時(shí)幾十年，不是幾百年。
That means sea levels will rise,
如此一來(lái)，海平面會(huì)升高，
inundating coastal areas and river deltas and endangering more than 100 million people.
沿岸地區(qū)與河口三角洲會(huì)淹沒(méi)，危及1億以上的居民。
Beyond that,rainfall patterns will undoubtedly change,disrupting agriculture.
此外降雨形態(tài)勢(shì)必會(huì)起變化，因而妨礙農(nóng)業(yè)活動(dòng)。
And weather extremes of all kinds will get more extreme.
各式各樣惡劣的氣候也會(huì)變本加厲。
Hurricanes and typhoons are predicted to become more powerful and destructive;
預(yù)期颶風(fēng)、臺(tái)風(fēng)的威力會(huì)更強(qiáng)、破壞力更大。
wet areas are likely to get wetter,triggering floors,while hot,dry parts of the world could get even more arid.
潮濕地帶會(huì)更加潮濕，引起洪水，而干旱地帶會(huì)更加干旱。
10.Because the changes will be rapid,natural ecosystems-wetlands,rain forests,savannas-may be unable to adapt.
因?yàn)樽兓瘉?lái)得太快，各式天然生態(tài)系統(tǒng)——沼澤、雨林和草原——可能會(huì)來(lái)不及適應(yīng)。
Animals and plants that have evolved to live under a certain set of climate conditions will suddenly face different circumstances.
動(dòng)植物經(jīng)長(zhǎng)期演化，可以在某種氣候狀態(tài)下生存，突然之間要面對(duì)不同的氣候狀態(tài)，
Many will go extinct.
所以有許多會(huì)滅絕。
And the potential for deadly disease outbreaks will rise:
致命疾病大流行的機(jī)率也會(huì)增加。
warming waters will be more hospitable to germs like those that cause cholera;
水溫升高，有利于像霍亂菌等病菌的繁殖。
disease carriers such as the Aedes aegypti mosquito may find they can survive nicely in places like northern Europe and the U.S.,making illnesses such as malaria more widespread.
像埃及斑蚊這種病媒可能在北歐、美國(guó)這種地方存活良好，所以像虐疾之類的疾病會(huì)更普遍。
11.The good news is that this gloomy scenario may galvanize the world's government into taking serious action.
好消息是：這幅陰郁的景象也許能刺激各國(guó)政府認(rèn)真采取行動(dòng)。
The first line of attack,says Florentin Krause,an IPCC contributor and director of the California-based International Project for Sustainable Energy Paths,should be "no regrets" actions-
IPCC成員，也是加州的國(guó)際永續(xù)能源計(jì)劃負(fù)責(zé)人克勞斯表示，首要的行動(dòng)應(yīng)該著重“不必后悔”的行動(dòng)——
changes that will be beneficial no matter how much of a threat global warming turns out to be.
亦即，不論全球溫度上升的威脅實(shí)際上是大是小，做起來(lái)都有好處的一些改變，
Among them:promoting the use of energyefficient appliances and cars.
例如提倡使用能源效益高的器具與車輛。
But the IPCC report,says Krause,makes it clear that nations must do more.
但克勞斯也說(shuō)，從IPCC的報(bào)告看來(lái)，各國(guó)該做的顯然不只這些。
For example,though it's now more costly to generate electricity from solar cells than from gas or coal,
比方說(shuō)，用太陽(yáng)能電池發(fā)電的成本目前雖然高于燃油或煤炭，
using the sun's clean energy could save money that would otherwise have to be spent in the future combatting the effects of global warming.
可是利用干凈的太陽(yáng)能，以后就不必再花錢去對(duì)抗溫度上升的惡果。
12.The encouraging precedent is the Montreal Protocol for ozone protection,
有一個(gè)令人振奮的先例就是保護(hù)臭氧層的《蒙特利爾公約》，
which showed how quickly nations can act when they finally recognize a disaster.
它證明世界各國(guó)在終于認(rèn)清了災(zāi)難的時(shí)候，能夠快速動(dòng)員起來(lái)。
A related lesson is that if CFCs do disappear,
連帶還有一個(gè)啟示：如果氟利昂制冷劑真的銷聲匿跡了，
it will be partly because chemical manufacturers discover they can make a profit by selling safer replacements.
部分原因是化學(xué)廠商發(fā)現(xiàn)販?zhǔn)郯踩奶娲闷芬部梢再嶅X。
The same process may ultimately be what mitigates global warming.
這一共同作用將來(lái)可能是減緩溫度上升的法子。
After long years of effort,
經(jīng)過(guò)多年的努力，
manufacturers of solarpower cells are at last close to matching the low costs of more conventional power technologies.
太陽(yáng)能電池廠商終于快要把成本降到和傳統(tǒng)發(fā)電方式相同了。
And a few big orders from utilities could drive the price down to competitive levels.
公用事業(yè)公司下幾張大訂單，就可能把價(jià)格壓低到具有競(jìng)爭(zhēng)力的水平。
If that happens,then all nations,from the rich to the poor,
果真如此，那么世界各國(guó)，不論貧富，
may end up working to save the atmosphere for the same reason they've polluted it:pure economic self-interest.
最后可能會(huì)朝向挽救大氣層而努力，原因和當(dāng)初污染空氣的原因相同：純粹為了本身的經(jīng)濟(jì)利益。
