Earths atmosphere 0.0004% co2, of which only 3% is from humans, which equates to 0.000012% of earths atmosphere!
Wrong, wrong, wrong, wrong, wrong...
It's 0.04%. Not unlike the blood alcohol limit for driving.
Over 40% of that has come from humans since the industrial revolution.

Atmospheric CO2 levels have increased from about 315 ppm in 1958 to 378 ppm at the end of 2004, which means human activities have increased the concentration of atmospheric CO2 by 100 ppm or 36 percent.

That's 36%
since 1958.
Our contribution is rising.
THAT IS THE ISSUE. If it stopped now, we'd be fine. But it's not. We're getting drunk in the corner.
If my blood alcohol level was 0.04% that sounds like a very small number, yeah? But I have to drive home.
Should I start drinking stronger drinks? That's what you are advocating.
The layer of glass in a greenhouse is even less than 0.04%. The greenhouse effect is irrefutable.
