As we move from coal based to natural gas based electricity generation around the world, the amount of CO2 emissions as a percentage of energy produced will naturally decrease. There are fewer carbon atoms attached to natural gas than coal, and as a result, less are launched into the atmosphere as a by product of burning it for power. Even if we do nothing other than let the natural gas revolution take root, the amount of CO2 in the air, and hence the amount of global warming will be reduced significantly.
tl;dr if CO2 does cause global warming, it will be fixed on its own
