Carbon dioxide can be sequestered by pumping it through water to grow algae with it. This is a new technology that is still being refined but there are large scale algae farms in California, Arizona and Texas right now. They feed the carbon dioxide to the algae in an algae farm and then extract oil from the algae that is grown. Algae can yield fuel oil, hi-test gasoline, jet fuel, a crude 'algae oil', ethanol or some combination, depending on the type of algae and how it is processed. It can be dried with the same residual heat power plants in Europe use for 'co-generation' and the solid material left over from processing can be used as feedstock or mulch. The algae oil is proving to have as many useful componants as crude oil and big companies like Dow Chemical and DuPont are working with it in test plants and research.
Once power plant operators start to realize that each ton of CO2 that they pump into the air (or pay to 'sequester') can yield six hundred pounds of fuel our problems with CO2 may reverse themselves, so the 'short answer' to your question is that in a way, it is possible that carbon dioxide will solve the global warming problem (at least it could if we start using it positively and stop wasting it and wrecking our air with it).
