Super villains aren't the only ones who want to shade the Earth from the sun. Blocking some of the sun's rays could slow climate change by reducing the amount of sunlight warming the Earth, say some researchers, such as Roger Angel of the University of Arizona.
The Convention may consider banning or limiting research into space sunshades. Some question their wisdom. A space sunshade would have a rapid effect on global warming and provide time to develop more permanent measures, they say. The technique has already received serious attention from NASA and other organizations.
