You aren’t going to debunk it, because like it or not the fundamental reality is true...
Yes, CO2 is a mild greenhouse gas.. and yes, combustion, by humans is increasing its concentration in the atmosphere.
The fundamental theory, that more CO2 will cause more greenhouse effect is solid. This is very demonstrable, and repeatable.
The problem comes in when you attempt to quantify the effect... and when you do that, you don’t get the doom and gloom scenarios, or really anything close to them.
The reality is, there is indeed a threshold at which our atmosphere would indeed hit a runaway CO2 cascade effect and wind up like VENUS.. but the reality is, that level is so far beyond anything that we are looking at that its comical. We are not on the verge of some worldwide collapse of life because of CO2 emissions.
The problem is the chicken littles are flat out lying and overselling this, for political purposes... The science, real science, does not back up their hyperbole.

True, but it is very minor compared to water vapor (the biggest determinant of warming) and methane, a secondary cause greater than CO2.

In theory true, but it is overshadowed and very minor compared to warming by other causes (mainly solar radiation). In fact, the historic record (from ice core samples) shows CO2 concentration increases lag temperature increases by several hundred years.

Very true. The doomsday models very much exaggerate the effect and provide the proponents of government control of economy, lifestyle, wealth redistribution, etc. with their excuse to legislate controls on all of the above.

Also true; in prehistoric times CO2 was much higher and the collapse of life resulting in the demise of the dinosaurs was likely due to a meteor strike while other atmospheric/solar changes likely have reduced the CO2 concentration to approximately what it is today.

Indeed, so true and so sad.
It’s water vapor, not CO2 molecules.
