While CO2 is certainly a problem, it is a problem with most sources of energy, except for solar, wind and nuclear. I think we would all rather choose solar and wind for now, although the nuclear power industry has increased its output a LOT over the past 30 years post Three Mile Island (by a factor of 3).Thus we can still brag on the natural gas with the reduced pollutants. Not perfect but its a better bridge to the next generation of clean fuel.
