THANK YOU for that chart.
Now overlay atmospheric temperatures on that chart for teh same period. Once you do that, you have conclusive proof that CO2 increase in the atmosphere have had no measurable effect on retaining heat in the atmosphere. Take your time & think about it why the “theory” is not happening in the real world.
(pro tip: people have no accurate records of global atmospheric or co2 concentrations even 1000 years ago, muck less 160,000. It’s an estimate with very low accuracy).
