Why is this better than trying to get off fossil carbon and removing
CO2 from the atmosphere?

Levees mean you're increasing the number of possible failure points; bad
engineering if you can avoid it.

Sunblocking schemes don't stop the acidification of the ocean, and
create another global failure point if relied upon long-term rather than
used as a stopgap before reversing carbon emissions.  You're also
blocking more and more of the light that drives photosynthesis.

We have no real idea of how to do MNT or AI.  We know how to build solar
plants, nuclear plants, solar ovens, Franklin stoves (more efficient
wood use), energy-efficient homes, biochar, etc.  Why do you want to
rely on the magic tech and not the proven tech?
