Cause of global warming discovered

Turns out this global warming fad is nothing new.  In the July 1932 issue of Modern Mechanix is this article placing the blame for global warming on carbon dioxide.  Note that people are still ultimately at fault, but apparently over time, what people are doing to cause global warming changes.

DR. E. O. HULBURT, physicist of the naval research laboratory, Washington, has found conclusive mathematical evidence that the earth’s temperature is being warmed by the increased amount of carbon dioxide present in the air. Smoke stacks emit huge volumes of this gas, which is also found in the breath and waste products of humans and animals.
