certainly - there have been enormous advances in science & in Climate Science since the time of Arrhenius.You really need to look into how the science has progressed since then.
CO2 does not retain heat. It acts as a transmission mechanism into the broader atmosphere. The radiant energy captured by a CO2 molecule is transferred through collision to other molecules (such as N2, O2) within about a nano-second.
CO2 at current concentrations is saturated at the principal wavelegth of radiant energy involved (15um). This means that it cannot transfer more heat into the atmosphere than it currently does.
The argument is then made that "collision broadening" occurs. Maybe, maybe not - the atmosphere is open, not a closed pressure system in a lab. But even this has been shown not to give you the catastrophic temperature rise you crave.
& what Arrhenius predicted over a century ago about the relationship between atmospheric CO2 & Global Temperature is being proven correct.
& the advances in science that you refer to, have enabled us by analysis of ice cores, to reconstruct temperature & CO2, back several hundred thousand years before Arrhenius' time,
& again - the temperature/CO2 relationship is as predicted by Arrhenius.
looks like your ….………...…….…. ahem ……………....…. "collision broadening" LOL !!!!!
comes into play whenever CO2 has increased over the past few hundred thousand years,
& this "collision broadening" has resulted in increased global temperatures,
& continues today to result in increased global temperatures.
