alt Hacker NewsI agree, plus were would one store the CO2 ? To get back to "1980", I really doubt puling CO2 from the atmosphere will ever work.
Another concern, who will pay for maintenance ? See this for why you cannot let CO2 escape from underground storage:

If stored near a populated area, hundreds of thousands could be kill, including all animals and insects, in a matter of minutes if the "vault" has a catastrophic failure. I would rather live near a nuclear waste site than a CO2 Site.

If it's between immediate death and a slow one of cancer, I'm not sure your choice is the obvious one.
Well as far as storing it goes, if you can capture it, turn it into a solid and stick it in the ground.
Imagine you were growing a huge biomass that you harvest, dry out, and then store. We know how the bacteria and processes that stripped co2 from the atmosphere in the past, we just need to do that in a big way. Good thing we have places on earth that are huge and flat and growing algae won't be a problem.
And then we complement that with green energy and an attempt at net zero.
Can't we just store C and let the O2 back in the air like plants do? We could store it right where it came from, in old coal mines.
