Injecting sulphate particles into the stratosphere, for instance, would cool the Earth by reflecting more sunlight into space.

The mission was to attach a HD video camera to a weather balloon and send it up into the upper stratosphere to film the blackness beyond our earth.

这项任务是把一个HD高清摄像机系在一个太空探测气象气球上，放飞到同温层上面，拍摄地球外面的黑暗。

You may or may not know about the Outer Space Stations positioned around Earth within your Stratosphere which are staffed with men and women from Space, some from Venus herself.

你们可能或许并不知道外太空的太空站，它在你们的平流层中环绕着地球，上面的男男女女来自外太空，有一些来自金星。

Ken Caldeira of Stanford University, another of the authors, reckons that it may be feasible to place sulphates in the stratosphere near the poles and thus cool the Earth in a place where global warming manifests itself most strongly, though that would scarcely please the Russians and the Canadians.

ECONOMIST: Global warming

Injecting sulphate particles into the stratosphere, for instance, would cool the Earth by reflecting more sunlight into space. (Nature has already shown that this concept can work, since volcanic eruptions that send sulphur-rich plumes into the stratosphere can temporarily alter the world's climate.) However, Dr Lenton notes that the method becomes less effective as the atmosphere becomes more saturated with particles.

ECONOMIST: Geo-engineering

Research can run far into the stratosphere, but it has a real-world component pulling it back to earth.
