Researchers want to use the ultrafine rock particles left by eroding glaciers — called ‘rock flour’ — to suck climate-warming carbon from the air ( wapo.st )

Sounds like more snake oil to me

Wow...that's...ironic.

The faster the glaciers recede, the more rock flour we'll have, and the quicker we'll be able to fix the issue!

Do we know how much there is and how much we will need? Seems like a huge problem. Maybe electrify everything and transition the economy to low carbon is a safer bet.

If all of the glaciers recede, we should have all of the rock flour. That should be enough?

It’s a big problem and I don’t know if the science behind this has been tested. Still, every little helps!

We’ll need more! Maybe there is more rock flour on other planets we can harvest.
