Probably Easier To Just Do The Three Rs

From The Guardian:

The US government wants the world's scientists to develop technology to block sunlight as a last-ditch way to halt global warming, the Guardian has learned. It says research into techniques such as giant mirrors in space or reflective dust pumped into the atmosphere would be "important insurance" against rising emissions, and has lobbied for such a strategy to be recommended by a major UN report on climate change, the first part of which will be published on Friday.

The IPCC scientists have examined these options, and note politely that they are "uncosted". They're along the same lines as the lets-erect-a-sea-wall-to-protect-our-coastal-cities type solutions. They'll cost gazillions, probably won't work, and whose going to pay for them anyway? The same people who won't raise gas taxes half a cent because it'll allegedly destroy Western Civilization are going to find the money to launch a mirror a thousand miles from end to end? Is Exxon going to be funding it? Shell? Who?
