Argument: Sulfur dioxide solar shielding is an economical solution
- Debate: Geoengineering, solar shading - pro argument.
Catherine Brahic. "Solar shield could be quick fix for global warming". New Scientist. 5 June 2007: "These schemes are almost too cheap and easy. Just one fire hose spraying sulphur dioxide into the atmosphere would do the job for a century. That would cost about $100 million - nothing in comparison to the hundreds of billions it would take to transform our energy supply."
Bryan Wassh. "6. Geoengineering". Time, What's Next in 2008.: "the price tag: somewhere between a few hundred million dollars and a couple of billion dollars a year, compared with the unknowable cost of decarbonizing the entire world."
