One strategy that’s been proposed to help humans avoid global warming’s worst consequences is carbon sequestration, in which carbon dioxide would be pumped into rock formations deep underground to prevent it from warming the atmosphere. Now researchers say they’ve discovered a basalt formation off the Pacific coast that could hold emissions from all U.S. power plants and factories for the next 120 years.

Superficially makes more sense than vast arrays of plastic tubes on the ocean floor.
The head scratcher comment is this:
“It’s going to require a much more significant infrastructure investment than other carbon-sequestration concepts,” he says. But Goldberg thinks that the advantage of having the carbon dioxide sequestered so far from human populations may eventually prove worth the extra cost
CO2 is dangerous to human populations? How? Well only if its dispersed through the atmosphere and contributing to global warming, that's why we're worried about it in the first place. If sequestering makes sense, then whether its underneath our feet, or far away someplace, the effect is the same. It ain't in the air no more!
