Burying CO₂ isn't the problem.

Keeping it buried is the problem.

......like nuclear waste in many respects.........

You had better hope they can't keep it buried. Every pound of Carbon buried also buries a little more than 2 pounds of Oxygen that does not get returned to the atmosphere. (12 grams of Carbon combines with 32 grams of Oxygen). The only sustainabe solution is restoring closed canopy tropical rainforests that have been lost, or find a way to grow plants on all the square miles of vertical surfaces we have built over the last hundred years. That last one might be a solution for growing food for a growing population, also.

Of course, a good sequestration program might go a long way toward controlling excessive population growth.

Why don't they just make it into diamonds?
