The desire to experiment with the skies

When quiet discussions about climate change erupted in the 1960's, scientists began tossing around ideas to combat global warming. By introducing sunlight-reflecting particles into the atmosphere, they could increase reflectivity slightly, counteracting heat-trapping gases, and thereby cooling the planet.

Colombian Dr. Broecker's idea was to introduce sulfur dioxide into the stratosphere in the 80s. By 2006, Dr. Crutzen, a Nobel laureate from the Max Planck Institute began publishing reports on how that might work to cool the planet.

One of the main inventors of the hydrogen bomb, Edward Teller, thought that, "Injecting sunlight-scattering particles into the stratosphere appears to be a promising approach and wrote to The Wall Street Journal, "Why not do that?"
