I would just like to add that the source of the excess CO2 that is now being
measured is fossil fuels. This is no guess, the isotopic ratio of the carbon
in the "new" CO2 is identical to that found in fossil fuels.

I also note that Andre did not explain how the increasing levels of CO2, a
known greenhouse gas, could be failing to produce a greenhouse effect,
instead he said that this was "irrelevant".

How do scientists recognize 'new CO2'? Is it by the gauche manner of the
molecules? Their clumsy attempts at Brownian motion?

The 'greenhouse effect' of CO2 is many times smaller than that of H2O
so Andre is right; it is pretty irrelevant.
