Build a fleet of controllable, thin, mirror satellites in earth orbit on the plane of the ecliptic. Like an artificial ring system for earth. Something like huge flat mylar mirror sheets with an outer foldable spring rim so they can be packaged small and pop open on deployment. Using an magnetic field generated by electricity flowing through looped coils on their perimeter they could be angled relative to the Earth's magnetic field. On the sun side of the orbit each one can be used to cast a controlled amount of shade from parallel to perpendicular. Enough of them - say 2% of the Sun-facing profile of the Earth could reduce incoming solar radiation by the same amount, but in a controllable fashion. In other positions they could be used to direct solar radiation to specific areas by pointing their mirror surface at the appropriate angle in orbit. You could heat up bodies of water to produce cloud cover. I imagine that you could, with trial and error, and lots of modelling, have a degree of climate and weather control.
