So the tube must have warmed up. Proof would be a temperature rise in the tube.

There was a control. He showed the image before and after CO2 was placed inside the chamber. Therefore, before CO2 was the control.

perfect demo

Your point being? Water vapor in the atmosphere is obviously self-regulating as a result of its boiling point being much higher than earth's average temperature. While the temperature of the gas leaving the cylinder would be SLIGHTLY cooler than the surrounding air (the flow is extremely slow) it would equilibrate with the surrounding temperature of the chamber and air within seconds. It is demonstrably NOT the cause of the disappearance of the flame on the thermogram.

Do this experiment with water-vapour and end up with the same result. I also woundering about the CO2 gas as its COLD as it leaves the tube and that is very important.

Not quite. Ice core samples show CO2 to historically be an effect of temperature rise. That does not indicate that it is not a cause. Actually, this should make you very worried. If increasing CO2 does cause warming, then the warming wil release more CO2, creating positive feedback.

Reality in upper atmosphere has been measured. AGW is a hoax, CO2 is not a greenhouse gas

Ice core samples show CO2 lags temperature rise; it is an effect rather than a cause
