Does that matter? The only thing that can be done, is for oil producers to stop digging up fossil fuels. And not even Norway is willing to do that, to say nothing about Russia or China, even this year. And that, not digging up the fossil fuel is the only way. If it's dug up, it will be burned. Guaranteed.

Oh and it effectively doesn't matter: to merely stop global warming we need 99.7% less fossil fuel production (and that needs to include everything from Saudi oil to Japanese coal)

So why would it matter? Because we feel it? We are not willing to implement real policy when we feel it. We are not willing to implement real policy when we don't feel it.

And geoengineering ... while it at least has the possibility for someone to just do that without the agreement of everyone ... so at least there's the realistic option to do something, so many nations, so many people, have their lives utterly dependent on climate change continuing. So nobody's making serious plans for that either (because, realistically, it'll mean war if something like that is implemented. Which is still better than doing nothing imho)
