They have not even quantified the amount of heat automobiles give off as they operate their internal combustion engines. They really do not care about the warming. Only care about the crisis and their tyrannical solutions.
That is because the amount of heat from engines is insignificant.
The only way that they get significant warming is to claim that CO2 causes a little warming which then causes a type of cloud increase which triggers a feedback loop that results in significant warming.
All the "proof" is in computer models that cannot be validated, by their very nature.
