We should also consider that as the ambient CO2 density rises we're also going to lose a lot of our cognitive function. If we're going to rely on nuclear energy to see us through we might need to rely on AI to carry on operations for us.
I'm skeptical of that claim without some good supporting evidence. Submarines tend to maintain CO2 concentrations 10x higher than atmospheric, and they have a better reactor safety record than civilian power plants.
No. The CO2 increases won't be at this level.
Or alternatively, personal CO2 scrubbers (already used as a part of diving rebreathers) become standard equipment for knowledge workers.
