Sigh... If only a method for converting carbon dioxide emissions into another gas actually existed in nature.

Plant trees and burn coal? That’s your plan?

Every time I read something like this, my hubris alarm goes off. We couldn't even get trans-fats right, so I don't see how we're going to cover all the contingencies for something like this.

Well, you need the trees to make more coal. Think of the children.

Lots of methods exist, but they're too expensive or don't scale well.

Exactly. Scalable solutions to deal with the waste don't exist.
