How can you quickly reverse global warming? It has been hypothesized that reducing sunlight by only 1% should eliminate this problem. Various ideas have been floated, from placing reflective sheets on the ocean or in space to exploding a controlled series of hydrogen bombs to stimulate a nuclear winter. Yes, some of the propositions have been certifiably insane. (To the left is a cloud ship, a concept from the University of Edinburgh, as funded by Bill Gates.)
The concept that has gained the greatest traction is the stratospheric sulfate solution (S-cubed), where large amounts of sulfur dioxide are, through various mechanisms, placed at altitude. This gas would form droplets of sulfuric acid in stratocumulus clouds to reflect back sunlight into space. Names like Freeman Dyson, Paul Crutzen and Edward Teller appear as advocates. This cure might cost $100 billion/year, for the effect wears out after a year, but that is a piffle in comparison with the $45 trillion exclaimed by the International Energy Agency as necessary to insure that our surface temperature only increases by 4 degrees Fahrenheit by the turn of the century.
