How does that establish or even TEND to establish that an infinitesimal addition of CO2 to a planetary sized system has ANY measurable effect on global climate?
Does it establish that adding CO2 to an atmosphere COULD see temperatures rise?
It tells us not one thing we didn't already know. CO2 COULD kill us all -- like if we eliminated all free oxygen and replaced it with an equal amount of CO2.
Of course, replacing O2 with Nitrogen gas could do the same thing.
The question is not "does CO2 have the theoretical potential to change planetary temperature?"
The question is, "is there any scientific evidence that the relatively miniscule additional amount of CO2 added by humankind to the planet's atmosphere has any actual impact on the planet's climate?"
As to THAT question, the OP's video lecture / demonstration offers not even one tiny bit of a hint.
Right - so the experiment has shown that CO2 CAN cause warming under certain circumstances.
Which is all it set out to prove.
The amount of CO2 released by human acitivity isn't minsicule by the way, though it may seem so when expressed as a % of the total. But it really is an enormous amount - check it out here:
