The chemical reaction of lime with carbon dioxide is:
CaO + CO2 = CaCO3
and would work quite well if you could find any cheap CaO without emitting a whole pile of CO2 in the manufacture of it; and you can’t! Lime (CaO) is made out of limestone by reversing the above reaction by heating above about 700 degrees C. So it makes just as much CO2 as you could absorb. Even worse, the heating is usually done by burning oil or gas and that liberates much additional CO2. You can’t win!

Or change CO2 into CaCO2 (limestone) cheaply and quickly. Then market the limestone for buildings, pathways, etc. I haven’t even googled this, but I bet there is someone looking at doing just that.

Too bad science can’t come up with something small that you can drop into the ground that will change CO2 and H2O into a solid form about the same consistency as wood…

global warming occurs every 1000 years, lasts 500 years. cooling will start soon,
without your help. carbon dioxide is a result of your killing plants, especially
phytoplankton, using chlorine and herbicides. we cannot control polluters;
but you can reduce co2 by planting plankton…

Whatever happened to the plan of shooting huge geysers of water into the atmosphere? That one seemed promising with little chance for chemically contaminating the ocean or atmosphere.

I don’t see what all the fuss is about. Man will have destroyed the atmospheres ability to sustain him in a few more years and we will simply die off, At least enough of us so things will level out again. Man had his chance and chose poorly. Fast and easy vs long haul responsibility. Nothing changes.
