I don't think you have a choice but to pull CO2 back that has already made it out, or is about to make it out, because we are not overnight shutting down all the coal plants.
My personal view is the true long-term storage is mineral carbonates, which is some form of accelerated weathering.
The idea that somewhere in the desert far away you have a CO2 absorber that's removing the CO2 from the air is an attractive one. It's a costly process that many will say is too expensive, but so are fuel cells in cars. It's a matter of political will to move this forward.
If we want to stabilize the carbon dioxide in the atmosphere at some level - it really doesn't matter which level - you end up having to stop emissions virtually completely.
We need to figure out a way to create more energy on a gigawatt scale and not create so much CO2 in the process.
If carbon came out of the ground, it has to go back into the ground.
Technologies simmer along before they are feasible. That simmer can be short or long, but then they get traction. And from there to being huge is a couple of decades.
I believe that it is impossible to stop people from using the fossil fuels, so we need to develop technologies which allow us to use them without creating environmental havoc on the planet.
Either you abandon fossil fuels, or you find a way to get that carbon back.
Injecting CO2 into an underground reservoir would certainly change the local environment and thus affect the organisms that live there. Some will thrive, and others will suffer. While we should minimize such impacts, they cannot be avoided completely. The same happens when one plows a field, builds a house or a road, or waters a lawn.
A car produces about one pound of CO2 per mile. There is no problem with collecting the CO2 in the tailpipe, but one might easily end up with a trailer hitched to the car for carrying all this CO2 back to the filling station. The gas burned from a 15-gallon tank would fill up five 60-inch-tall gas bottles.
In a well-monitored storage site, it is always possible to release CO2 in a controlled manner in the unlikely event that it threatens to escape. Such a release is certainly no worse than ignoring the emission in the first place.
