Since Randall Carlson is a three hour video, the easiest way to sort this out is by reference to science fundamentals
- Are CO2 levels rising?
 - Are CO2 levels rising unusual?
 - Are CO2 Levels changing at an unusual rate? (if so, what is the cause?)
 - Is it possible to measure CO2 in air bubbles in Ice?
 - Does CO2 absorb/block heat?
 - Does CO2 level rise have any consequences?
 
if his conclusions conflict with the fundamental facts of science, then I do not have go wading through all of his other material.

and as I said before, that could be bullshit. Carlson show compelling evidence that it is bullshit.
