Any air (flue gas initially) scrubbing will be competing with 
burning fossils (apropos burning fossils, Denmark outlawed fossil 
burners in new home heating). Don't see CO2 levels slowing
down before 2080, nevermind reversing. By that time methane
and water will dominate the greenhouse effect.

Any massive SPS constellation in LEO will automatically cause
shading all by itself.

Sounds suspiciously like zombies.
