This is some really nifty stuff. Thanks for posting the article.
That said, I don't think that this will stop global warming. Ant mounds are relatively porous soils, right? Well, calcite/dolomite (CaCO3 and
CaMg(CO3)2 respectively) are the minerals that make up most limestones (calcium carbonate). These mineral species are highly soluble in acidic
conditions. Even slightly acidic rain (as in most rain nowadays) can dissolve the mineral. I've been on an outcrop of soft limestone (rock, not
just grains of mineral in loose soil) in the rain, and it bubbles.
Now, dissolving the calcite will only release the CO2 back into the atmosphere... (Funnily enough, most rain is acidic because of dissolved CO2 in
water, which will form carbonic acid...). It's neat, but it is already a part of the cycle, and sequestration would likely only be for a short
period of time. You could consider it something akin to growing a tree, then burning it for heat, and then growing another tree. Really, the CO2
isn't permanently captured (or even captured in the long term) from this, and I think the ant calcite would likely be a similar scenario.
Of course I'm not expert, so take all I say with a grain of halite. Thanks again for the post.
