Direct conversion of CO2 to solid carbon by Gallium-based liquid metals

Read about solar radiation management. Space based approaches aren't necessary. You can put the equivalent of sunblock in the upper atmosphere or seed more low clouds. It's relatively cheap but there is a lot of opposition to the science.

@dr_shiv & @DemocracyFTW (I don't recall if HN notifies of mentions)

Is the "opposition" mainly that the process as stated isn't reversible? Is there a way to improve the original idea to make it reversible in a short order?

Well, marine cloud brightening is small scale and involves lofting salt water in the air. It is immediately reversable.

The opposition comes from political signaling and tribalism.

That's not "opposition to the science", that's a sane response to a madman's proposal to intentionally f*k with the biosphere at the grandest scale.
