Blocking solar rays. Sucking carbon dioxide from the atmosphere. Ideas that sound like science fiction are now starting to become reality, raising concerns about safety.
I’m always thinking it as an energy problem. Using up energy to suck up carbon isn’t 100% efficient, and tech to suck up oil isn’t either. So trying to undo the damages of the latter, we produce even more CO2 (building those and also running those ( even just by supplying remote areas with stuff)) and then use up valuable energy, so we can just go on ignoring that we’re burning up a limited resource without much efficiency to start with.
