To quote the mag article:
"Composed of six-micrometer-long tubes, the micromotors quickly convert carbon
dioxide into the solid calcium carbonate, a mineral found in eggshells, calcium
supplements and cement. The enzyme carbonic anhydrase, contained in the
micromotor’s outer polymer surface, spe

$43T in damages seems like a lot to me, especially if spread over a century
or the period 2015-2100. Global GDP is about $78T.
I don't have access to the article, so can't comment in detail, but if I
did I would be trying to figure out what they imply is $T/degC/year. While

The paleocene-eocene thermal maximum is a better analogue, due to speed of
transition. It's still ~1000x slower than current climate change. Speed is
crucial, due to short atmospheric life of methane

I'll see if I can find that consideration or not at some point.

Dear Paul‹I would make one comment about a difference in the situation
between the present and the Eemian that might make a difference. For the
Eemian, the warming influence was an increase in summertime solar radiation,
which would indeed warm the summer season and surface melting of glaciers

Can't this overpressure problem be resolved by
A) pumping from an elevated base station or tower
B) aeration of the slurry with small diameter gas bubbles
C) using intermediate pumps, powered by H2, solar/laser power, or
