A more long-term solution would be
to create calcium carbonate by pumping it through lime slurry, or use it

Bull****. That lime is produced by removing the carbon dioxide from
calcium carbonate, and dumping it into the atmosphere. You turn
limestone into limestone, and you dump a lot more carbon powering the
useless process. Net loss, by the ammount of heat required to bake the
carbonate to the oxide.
