The main question is whether there's a carbon sequestration process which can be industrialized so that it's more effective than planting trees.

Not sure we want to start competing with trees -- what if we get better than them at it? Do trees start dying for lack of CO2?

If we could process enough CO2 to reverse current inputs(i.e. the equivalent of hundreds of billions of tree growth) we could possibly think about scaling up the process to remove all the CO2 from our atmosphere as fast as we can. But we won't run out of CO2 unless we take all the ethanol we're producing with the CO2 and store it, instead of generating energy from it via combustion.

It's not like we couldn't stop if the CO2 levels dropped too far.

Just like we are able to stop now, as the CO2 levels are life-threateningly high, right?
