　　A Sunshade for the Planet　　Even with the best will1 in the world，reducing our carbon emissions is not going to prevent global warming.It has become clear that even if we take the most strong measures to control emissions，the uncertainties in our climate models still leaye open the possibility of extreme warming and rises in sea level.At 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.　　Basically the idea is to apply sunscreen to the whole planet.One 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 suns rays.Its controversial，but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earths surface to counteract the warming produced by the greenhouse effect.Global climate models show that blocking just 1.8 per cent of the incident energy in the suns 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.　　emissionn.發射，發射物 heroinn.海洛因　　n.住院治療　　geoengineering n.地質工程 astronomern.天文學家 5triljEn7kauntE5rAktp　　百萬兆; 萬億，兆 7kCntrE5vE:FEl E5nAlEdVip　　adj.有爭議的　　注釋：　　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，在美式英語中它說成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 retreatsecure;and l have the right- hand seat inthe barouche.蓓墓想道：逼到最后一條路，逃難是不怕的了，在他的大馬車里，我穩穩地有一個位子了。又如：Ifthe worst comes to the worst，well sell the car.大不了我們把車賣了。　　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。　　1.
