Thank God someone is finally going to tell the truth about this.  I am getting 
so sick and tired of all those e-mails and papers about how this could be done. 
 The plan to "design" particles is either (a) a fantasy of frustrated 
scientists who are mad with those who have already grabbed the bull by the 
horns and think practically or (b) a not so clever attempt to try to sabatoge 
the work ongoing by redirecting interest into long term dead end projects.  I 
think it's both.  Don't agree?  Look at the list of authors.

Geoengineering through solar radiation management 
Wednesday, 17 December 
1000h

Even if society gave geoengineering with aerosols the green light today, it 
would be impossible to carry out, as there is no existing technology to put 
sulfur gases into the stratosphere. However, scientists are beginning to study 
how to design and introduce aerosol particles into the stratosphere to block 
solar radiation. New work investigates how the gases would form particles and 
what their sizes and properties would be. It also looks at how such aerosols 
would evolve in the atmosphere, circulate around the world, and finally exit 
the atmosphere.
