The Future of Terraforming

There are a few places like the Comanche of carbon places, few places that have carbon and deposits. Extremely rare. If you had a lot of carbon dioxide, where did you go? It must have it in the carbonates. We know almost nothing about the subsurface of planet Mars. The next 50 years will bring in much more information about the history of our neighboring planet. Maybe over the course of our lifetimes, we'll find out more and more terraforming.
