The cause of global warming is still under debate.” – Choi and Manousiouthakis, 2022
Radiative models estimating the temperature effects of increasing CO2 to 420 ppm indicate 0.64°C of the alleged 1.2°C warming since the 19th century could be explained by CO2 increases.

A 2013 study suggested only 0.26°C (<33%) of the warming since 1880 could be attributed to the 290 to 385 ppm CO2 increase.
Well, this backs up the heavy physics model of Happer who shows that increasing CO2 past certain levels does not increase warming by add’l heat absorption from the increased CO2.
