Carbon capture update

As I've posted here many times, the future of humanity in the second half of the 21st century looks bleak. Not just because of coastal flooding and desertification, but mostly because of the resource wars triggered by populations who need food and fresh water and are willing to fight and kill for it.

It's too late already for conservation to make a difference. There's already too much CO2 in the atmosphere and it takes decades to dissipate. Moreover, melting of permafrost and methane clathrates, together with decreasing albedo in places formerly covered by reflective ice and snow, will amplify the effects of anthropogenic greenhouse gas emissions.

The only hopes to avoid disaster are geoengineering and carbon capture. Planet-scale geoengineering is risky, since we don't know enough about controlling any of the current methods. That leaves carbon capture. While carbon capture technology to remove CO2 at the source is maturing, removing atmospheric CO2 on a global scale is still challenging and elusive, because the gas comprises such a small fraction of the air. Here's an update on carbon capture:
