Are you clear that 1% means one-hundredth? Many of your posts would be accurate if it were a thousandth, instead, but a percent is in fact a hundredth.
Thus:
7000/millionths = 7-thousandths = 0.7-hundredths = 0.7%
I screwed up a lot of those numbers. Bottom line is CO2 is very minor atmospheric gas and all the increases the greenies howl about are infinitesimal when all atmosphere gasses are included.
