How much energy do you think that will involve?

Does it matter, as long as the CO2 it produces is less than the CO2
taken out of the atmosphere during the life of the facility?

BTW, this is only one atmospheric extraction concept.

Simply dropping the mean ocean temperature by 1/500th degC compensates
for the entire annual anthropgenic CO2 production (a fact that itself
questions the anthropogenic argument). There are may ways of
implementing that and the oceans have a huge area.
