My first thought was that countries with money can flood other countries or the reverse, drought them out of existence by moving rainfall out of their reach. Fascinating stuff. I'm sure CO2 sequestration will have amazing surprises for those close to the point of sequestration. It's always best to do this sort of thing near the powerless. There's a reason New Mexico is where radioactive waste is stored. What could possibly go wrong? And if it does, do it in one of the poorest states in the country.
