Right. In a closed system, sure, put more free CO2 in the gaseous envelope and a body below should heat up at a greater rate than "mere" incident radiant energy would indicate. But planetary climate is not a closed system, so CO2 cannot be considered as a
de facto driver for this "global warming" thingie.
