We have a new paper out on how to use rocks to pull #CO2 out of the air and stabilize it as...rocks.
TL;DR: Surface rocks in Japan could remove 7.6 Gt-CO2/y at 1.5 GJ/t-CO2.
It's open access, so send it to your mother. I know I did.

We started with a map of all the surface rocks in Japan (~158,000 entries) including the depth of the formations. We narrowed it down to rocks with high Mg or Ca content. We then removed all populated areas, protected ecosystems, etc. to make a map of potential sites.

...this leads to a potential #CDR of 15,591 Gt-CO2...so more than we need for #2DS.
But, most of that rock is volcanic (amorphous).
Previously we found that amorphous compounds react >1,000X slower than equivalent crystalline compounds.
