Here's a better solution than glass bubbles or whatever geo-engineering stunt people come up with: how about we adjust our culture and attitude to value the biosphere instead of feeding it into a meatgrinder; to encourage companies to make things that last instead of making things that break and need to be thrown away; to look at our energy use and just stop using so much of it.

How about that?
