Climate Change Control Using Rock Dust

[parmalee]

each year, thousands of tons of crushed carbonate rock are spread on farm fields in Iowa, and more throughout the midwest corn belt.
Now if the same result can be had from a mineral that absorbs CO2 rather than releasing it
that would be interesting-------------and, then comes efficiency and cost effectiveness

And, not coincidentally, that's pretty much precisely what the paper linked in the OP addresses (among other thing).

"Other things" like:

Success requires incentives and regulatory frameworks that overcome social and political inertia. Silicate demand of nations must also be met in a way that facilitates social acceptance and preservation of biodiversity.

Deployment of any CDR strategy is inhibited by the concern that it may erode society’s perception of the climate threat and the urgency of mitigation measures

Though that "political inertia" part strikes me as a bit, I don't know, generous, but I suppose it's apt for a global audience.

ok
the paper had some interesting material
a tad lacking in details from my perspective
and I disagree with "is now necessary"
one helluva sales pitch

I do agree with the idea that action "now" is necessary. But piecemeal patches here and there are probably not anywhere near sufficient to avoid disaster.

What is required is a worldwide concerted effort to curb our CO2 emissions or a method to re-sequester the released CO2, on a worldwide scale.

and I disagree with "is now necessary"

Of course you do.

You're still trying to argue that the weather around Greenland during the last natural warming spell is evidence that the laws of physics formerly governing the planetary warming effects of CO2 have been repealed recently.
