It may sound like the crazed plan of a James Bond but scientists are working on a way to artificially cool the planet by reflecting sunlight away from the Earth. 科学家正致力研究人工降低地球温度的方法，他们试图将射向地球的太阳光线反射出去。这听起来真像是詹姆斯·邦德的疯狂计划。 In a largely theoretical field known as geo-engineering, a team of British academics is about to announce a world-first with plans to field test an artificial volcano as a solution to global warming. The concept is based on the cooling effect of volcano eruptions on the atmosphere. 一队英国学者打算实地操作试验，利用人造火山解决全球升温，这是世界地球工程学界的第一次尝试。此观念基于火山爆发对大气的冷却作用。 The eventual plan is for a helium balloon. It is anticipated that the helium balloon would have to be roughly the size of Wembley Stadium and tethered 14 miles above the Earth by a giant hose to contain the amount of chemicals required. It is hoped that the droplets of sulphates and aerosol particles will reflect the sun's energy back into space, preventing it from heating the earth. 最终决定建造一个和温布利体育场一样大的氦气球，由大软管拴在距地表14英里处，以控制化学需求总额。他们希望硫酸盐液滴和气雾粒子能够将太阳的能量反射回太空，以防止地球变暖。 |
