I don’t believe that it is.

My sibling comment even argues for needing to invest in technologies for removing carbon from the air because we need a way to remove the CO2 that’s already up there.

I believe that putting this same money into building more renewables is better use for the money. We can worry about removing CO2 from the atmosphere once we stop dumping immense quantities of it.

That being said, this problem is as much economical as technical. Microsoft, want to help reduce CO2 levels? Spend this money on lobbing to introduce carbon prices, e.g. see Canada’s carbon tax or the EU carbon tax WITH a border adjustment.
