Solving climate change by abusing thermodynamic scaling laws

Sadly, I don't think so. Many of these carbon burial/sequestration proposals all advocate just taking all of the plant matter and tucking it away, including the N and P.

I'd burn the wood, catch CO2 with oxides, store it as carbonates. The rest would go back to the environment.

Eli Yablonovitch has been working on this for a while. I thought it was assumed that only the lignin would stay sequestered but I'm not finding those details.

I wasn't satisfied with his idea because it assumed that the biomass had to stay dry indefinitely, despite being locked behind an impermeable barrier. It's also not very convenient geographically, because raising crops (at least for low-value types like switchgrass) is not economically viable in the driest areas where they would be stored.
