Dr. Edward Teller, who helped develop the atomic bomb 60 years ago, has turned his attention to possible ways to reverse global warming. Most scientists have decided that if current trends continue, the Earth’s average surface temperature will be 2.7 to 11 degrees Fahrenheit higher in 100years.

One solution may be to blast tiny particles into the atmosphere. The particles would deflect enough sunlight to trigger global cooling. Another plan would be to launch 50,000 mirrors into orbit to reflect sunlight back into space.

“The sooner, the better,” says Teller. “The simplest plan is to put into the high atmosphere small particles that scatter away one or two percent of the sunlight.”
