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.
As long as leading figures either claim it's a hoax or that it's not necessary to do sth about it, none of this matters anywhere.
This is less of a technogical problem than it is a political one, I'm afraid.
