Carbon dioxide is the thermostat of earth’s atmosphere. That was demonstrated by John Tyndall, a British physicist, in experiments done in his laboratory in the 1850s. Using a relatively simple apparatus he showed infrared radiation (heat) passes through oxygen and nitrogen gases unimpeded, whereas carbon dioxide, even in low concentrations, absorbs heat.
Light energy from the sun (a spectrum of wavelengths) passes to the earth’s surface with little absorption, bringing the energy that is transformed into heat at the earth’s surface. Carbon dioxide then traps it, hence, the name “g...
