It's proven science, it just requires space, material, manpower, and energy that makes it either unjustifiably inefficient at best or a net loss. You gotta read the fine print with optimism blindfold.

For instance, if you took all the money that went into funding this project and instead spent it planting trees you'd remove more CO2. Concrete isn't exactly carbon neutral and neither is the energy spent separating or storing CO2.

The amount of carbon that plants can capture is literally negligible.

The amount plants capture is already engaged in what you might term the Carbon Cycle. Which also demonstrates that plants' and animals' direct emissions are literally negligible, because these processes and the plants' recapture are or were exactly equivalent, and balanced.

Add to this hundreds of billions of tons of carbon from coal, natural gas, and oil, and that's the problem. This amount of carbon was formerly buried, out-of-the-way, below ground. Now it's in the air, and dissolved in the ocean. The plants are preoccupied with the amount of carbon there used to be in the air. This extra amount is beyond them.

But it's also unlikely Arizona is going to make hundreds of billions of tons of concrete, to sequester the difference.

Dunno what they pull it from but know people working on a pipeline that will take CO2 from one state and sell it to another to store or some shit to get credits. Apparently it’s BIG business. I

I think that kinda bullshit should immediately end the incentives and just tell them to cut it out. It’s already went from a potential positive thing to another way to exploit dumb shit for ridiculously sums of money.
