Cement and concrete are major sources of CO₂ emissions, and will continue to release carbon dioxide for hundreds of years after solidifying.
The terrestrial biosphere only looks like a good place to store carbon because it's so variable. But I'm pretty sure it's nowhere near enough to deal with climate change. The oceans are the key to this, with ocean acidification and the carbonate compensation depth being the major player. If you could get the CO₂ low enough to start dissolving rock instead of living coral, then you buffer the oceans and effectively remove the CO₂. This happens naturally, but on a time scale of 500+ years.
We're running out of time for solutions that don't look like massive geoengineering.
