      Technically, physics does allow a satellite-based method to deal with climate change. Economics, on the other hand, does not. You would need to chuck an unfathomable amount of mass into orbit.

        Do you though? I mean, a satellite orbiting the sun between the earth and the sun could cast a large shadow, right?

          If the sun was a point light source that is accurate. It is not though. You would need an absolutely enormous sat to cast a shadow that would actually affect our weather. Plus you would also need a way to keep it in position as the solar radiation would push it out of position quickly.
