Dr. Roger Angel, an astronomer from the University of Arizona has come up with a theory that he thinks will stop, and perhaps even reverse global warming. His theory involves a massive sun shield. The shield would cover about 100,000 square miles and be made up by trillions of mirrors that would be launched (fired) into space about one million miles above earth.
Using a huge cannon. At a cost of $350,000,000,000,000.
No - really:
So far, Dr. Angel has secured NASA funding for a pilot project.
A huge cannon?
One raises one's eyebrow.
