This could perhaps be part of the mix of strategies, but we shouldn’t slack off on our own efforts to reduce our pollution and greenhouse gases thru energy/resource efficiency/conservation and going on alt energy when feasible.
Another strategy could be BIOCHAR (tho there are also some questions about it*). It basically takes organic waste (like garbage, yard & agri waste) and burns it with very low oxygen & very low CO2 emissions in a process known as pyrolysis. The products include high carbon charcaol that make a very good soil amendment, increasing crop production, while storing the carbon in the soil. So the plant life used for it draws CO2 down from the atmosphere, but instead of being released during decomposition, most of it is stored in biochar and sequestered for 100s, maybe 1000s of years. Terra Preta (biochar created by ancient civiliations) is still in the ground 1000s of years later. The pyrolysis process also produces heat energy that can be turned into energy (like a cogeneration principle), and some biofuel that can also be used as fuel.

Since our area generates a tremendous amount of yard waste, which is collected by the city, that might be an ideal place for biochar operations – then it could be sold or given to farmers as a soil amendment.
Another problem in our area that could be used as a solution is carrizo cane, which grows along the Rio Grande River, which smugglers and undocumented people use as cover; it is an invasive species, which environmentalists dislike. Homeland Security started areal herbicide spraying of it 3 years ago, endangering the health of us who live along the border, and it was stopped. But I’m thinking that with some mobile pyrolysis units, they could turn carrizo cane into biochar, then sell it at low price to farmers. That might work out more cost-effective than their newer hand-cutting it & herbicide plan (they could subcontract it out to small business people, by providing them with the equipment).
*One of the concerns about biochar is the transport and application of it possibly involving black soot escaping into the atomsphere and causing environmental problems (like climate change) and the eventual release of the carbon back into the atmosphere, and it should not be used as a “carbon off-set” assuming we ever get involved in some kind of Cap&Trade (which I don’t see happening anyway).

I think the ultimate solution is going to be many solutions from many different angles. I hope this lithium nitrade works out, along with some 100s or 1000s of other solutions (like taking a hanky to wipe hands in public restrooms or using the blank side of used paper, and 100s of more things we can do)
