I think the "buying time" solutions do work, and will be needed, but indeed will be abused as cheap end-all solutions by idiots, as always.

Storing CO2 directly in the ground, I think, is a really bad idea. if it escapes you lose all the energy invested in harvesting it. You'll need to convert it into Graphite or plastics. The problem though is again that were talking truly ginormous amounts. Think a square kilometer cube of graphite, we'd need hundreds of those. If that were to catch fire, we're all effed, so your still need to store it safely somewhere.
