Negligible future warming from: CO2 – CH4 – N2O

At the current concentration of atmospheric CO2 at ~420 ppmv, (parts per million by volume), is at a low level in comparison with levels in past eons when plants evolved. At this concentration Co2 is already ~85%+ saturated.  

The Global warming potential of any added atmospheric CO2, whether natural or Man-made, is already virtually exhausted.

At its current concentration atmospheric CO2 at ~420 ppmv even doubling to 840 ppm would cause little additional warming, amounting approximately to a ~1% effect applied to ~33°C total Greenhouse effect or ~0.33°C.

The added level of CO2 increase would be a huge benefit to the biosphere and agriculture.

All attempts by Mankind to limit further CO2 emissions or other Greenhouse gasses will have no further controlling effect on Global temperature.

Any further actions by any minority of Western Nations to avoid a supposed Global Overheating Catastrophe by reducing their emissions of Greenhouse Gas are simply self-harming and pointless.

These facts entirely negate the obsessive need to pursue Net Zero policies at all.
