Solar Shade to Reverse Global Warming

Instead of trying to reduce the greenhouse gasses, what if you could block out the light from the Sun? Dr. Roger Angel from the University of Arizona has calculated that a solar shade 2000 km (1,250 miles) across would block enough radiation from reaching the Earth to reduce the warming effects of carbon dioxide emissions back to industrial levels.

It's surreal watching obscure theoretical concepts like this quietly plant roots in the mainstream.
