The Worst Idea Ever - Geoengineering

The latest geoengineering idea to combat global warming is both a ridiculous and dangerous.  While I do not see something so dumb ever getting past the drawing board, the notion of geoengineering general seems to keep popping up at a frightening level.  Does anyone see the problem in engineering our way out of a problem we engineered our way into?  In this case, the plan is to spray tonnes of aerosols into the upper atmosphere to reflect sunlight back out into space.  Our lack of understanding in the way nature works is what got us into this mess in the first place.  Further complicating the issue with more unnatural means does not seem like the solution.  Why not just attack the cause?  This would basically give industry license to emit as much as they want as long as they spray enough aerosols to mitigate their warming effect.  It is a reckless and stupid endeavor.
