It's only a political problem if you make it one. Better politics requires less technological innovation, and better technology requires less political innovation.

The political barrier suddenly becomes much less intimidating if an extremely efficient way to such CO2 out of the atmosphere manually was found tomorrow.

Thermodynamics kind of forbids efficient ways to suck CO2 out of the atmosphere. Unburning coal takes more energy than you got from burning it.

Source? Carbon capture and storage (CCS) seems to be a thing for sure.
