Saturn’s rings to solve global warming!

A wild idea to combat global warming suggests creating an artificial ring of small particles or spacecrafts around Earth to shade the tropics and moderate climate extremes.

There would be side effects, proponents admit. An effective sunlight-scattering particle ring would illuminate our night sky as much as the full Moon, for example.

But the idea, detailed today in the online version of the journal Acta Astronautica, illustrates that climate change can be battled with new technologies, according to one scientist not involved in the new work.

To keep the particles in place, gravitationally significant shepherding spacecraft might be employed. They would herd the particles much like small moons keep Saturn’s rings in place. LiveScience, 27 Jun 2005
