Here is proof that co2 is a coolant, also check the other video's with many different tests.

Vacuum fillament and argon (non radiating gas) fillament creates an higher temperature compared to co2 fillament, when exposed to infrared light.

The radiating and convection of co2 causes netto cooling. It cools the atmosphere and the infrared heat source.
