>I'm not convinced that putting sulfides into the stratosphere is a good idea as we don't have a sound understanding of what the effects would be. Neither am I, but everything I've read seems to indicate that SSI is cheap enough that many nation states could comfortably do it. That all but guarantees it will be done when places like china or india start losing tens of thousands of people to heat waves (See 'The ministry for the future' for a fictionalized account). We as a species are short sighted. We'll go for the quick fix and hope we can deal with the consequences later. The bad thing is we have no idea what those consequences will be or how to address them. It's completely uncharted territory.
