The excessive focus on carbon will eventually need to change.
The problem is average surface temperature, to which atmospheric carbon levels are only one of many drivers.
The most important driver of surface temperature is TSI. [1]. TSI can be economically moderated, as-needed, to cool the Earth. [2]
If we (as in Humans) ever decide we truly need to do such a thing, we can have all the infrastructure in place within a decade and for merely a few trillion dollars.
Perfectly reasonable for all the carbon to be left in the atmosphere when you control TSI directly through refracting a small percentage (e.g. 0.1%) of TSI by launching moon dust at L2.
People don’t want to admit it’s a relatively* easily solved technological problem, because then the social moderation aspect becomes less existential.
