　　A Sunshade for the Planet

Even with the best will1 in the world，reducing our carbon emissions is not going to prevent global has become clear that even if we take the most strong measures to control emissions，the uncertainties in our climate models still lea'ye open the possibility of extreme warming and rises in sea the same time，resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough.

Fortunately，if the worst comes to the worst2，scientists still have a few tricks up their the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the l now，that is.A growing number of researchers are taking a fresh look at large-scale “geoengineering” projects that might be used to counteract global warming.“I use the analogy of methadone4,” says Stephen Schneider，a climate researcher at Stanford University in California who was among the first to draw attention to global warming.“If you have a heroin addict，the correct treatment is hospitalization，and a long rehab. But if they absolutely refuse，methadone is better than heroin.”

Basically the idea is to apply “sunscreen” to the whole astronomer has come up with a radical plan to cool Earth;launch trillions of feather-light discs into space，where they would form a vast cloud that would block the sun’s ’s controversial，but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth’s surface to counteract the warming produced by the greenhouse al climate models show that blocking just 1.8 per cent of the incident energy in the sun’s rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere. That could be crucial，because even the most severe emissions-control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century，and that would last for at least a century more.

　　註釋：

1. the best will：最好的願望

2. if the worst comes to theworst：如果最最糟糕的事情發生了。這是英式英語的用法，在美式英語中它説成if worst comes to worst。在不同的語境中，有不同的澤法，如：“If the worst comes to the worst，”Becky thought，“my retreat“secure;and l have the right- hand seat inthe barouche.”蓓墓想道：“逼到最後一條路，逃難是不怕的了，在他的'大馬車裏，我穩穩地有一個位子了。”又如：Ifthe worst comes to the worst，we’ll sell the car.大不了我們把車賣了。

3. scientists still have a few tricks叩their sleeves：科學家們仍然有些不為人所知的招數。 have something up one’s sleeve是英語成語，意思是：to have a secret idea or plan，有錦囊妙計，有所保留的，祕而不宣的謀略或計劃，例如：If this trip doesn’t work out I’ve still got a few ideas up my sleeve.

4. methadone：美沙酮，一種有效的合成麻醉藥，它不像口馬啡或海洛因那樣容易汁人上癮，在戒毒治療中被用作這些毒品的替代品。
