Siphoning carbon dioxide (CO2) from the atmosphere could be more than an expensive last-ditch strategy for averting climate catastrophe. A detailed economic analysis published on 7 June suggests that the geoengineering technology is inching closer to commercial viability.The study, in Joule, was written by researchers at Carbon Engineering in Calgary, Canada, which has been operating a pilot CO2-extraction plant in British Columbia since 2015. That plant — based on a concept called direct air capture — provided the basis for the economic analysis, which includes cost estimates from commercial vendors of all of the major components. ...Assuming that CO2 is buried to offset vehicles’ emissions of the gas, a price of $100 per tonne would add about $0.22 cents to the price of a litre of fuel, Lackner says. That’s a substantial but not unprecedented price increase, he adds.
The cost of solar continues downward and will soon be cheaper than even coal. That's the best solution. But this air scrubbing tech could also help.

Molten Salt Reactors running on ThF4 are the best solution ;)There's god knows how much Thorium lying around because it's a byproduct of Rare Earths Processing. It's just sitting there, waiting to be dumped and buried somewhere. Why not power reactors with it?
Yeah it's weird there must be some reason the Thorium reactors are not being pushed more. Haven't heard any scientific counterargument yet that would not make it worthwhile.
Wouldn't it be cheaper and easier to stop population growth and reduce population? This is just a bandaid for a bigger issue.

RC2006 saysWouldn't it be cheaper and easier to stop population growth and reduce population? Ok you're in charge. How would you do it? And explain also why it is cheaper - considering economic growth so far depends largely on population growth.
Exactly @justmeCarbon sequestration is a bad joke!
