The people who believe in AGW caused by CO2 are the people who are denying science. The science of thermalization and the Maxwell-Boltzmann distribution of molecule energy explain why CO2 does not now, has never had and will never have a significant effect on climate.
Failing to recognize that CO2 has no significant effect on climate is an egregious mistake but is dwarfed by the potential disasters of ignoring what actually does. Discover the three factors in an equation which matches the measured average global temperature trend 98% 1895–2016. http://globalclimatedrivers2.blogspot.com
