Geoengineering 地理工程学 Implicit promises 包含着承诺 A geoengineering experiment has come unstuck.But there will be more 地理工程试验取得突破。可期待更多。 FOR the past few years, a European collaboration called IMPLICC has been looking at whatit might mean to engineer the climate, 近几年在欧洲合作平台上，简称IMPLICC的组织， by reducing the amount of sunshine that reaches the Earth s surface. 持续对减少阳光直射地球为目的研究做探讨。 A lot of IMPLICC s work, like much else in climate science, has taken the form of computermodelling. 探讨是为了解该项气候工程的含义。IMPLICC和其他气候科学研究相似，较多采用电脑模拟程序。 In its case the models try to mimic the effects of things like putting veils of reflectiveparticles into the stratosphere, 在这里，创造出的气候模型设法模拟出两种情况，其一是将层层的反光微粒放入平流层中， or brightening the clouds over the oceans. 其二是增加海洋上空云朵对光线的反射度。 This week the IMPLICC team andother interested parties met in Mainz, Germany, to discuss the resultsfor the variousmodels have turned out to agree far better than many of their creators expected. |
