They do not. We don't have to guess about this. We have empirical and scientific proof. I owned a Weights and Measures gas-physics test-and-repair facility and conducted tests. We learned gas physics from engineers at factories that manufacture gas-physics instruments. They must understand gas physics or their instruments won't work.
How academia got this wrong
In 1988 James Hansen flip-flopped from "global cooling" to "global warming" being dangerous.
Al Gore fed the fear with $22-billion annual funding for universities and professors to study the matter. Hansen's claim is a falsehood. People move to warmer climes for their health. Consider all the species, in the plant and animal kingdoms, that thrive near the equator and none survive at the poles.
