Now all you have to do is:

a) Demonstrate that CO2 is causal for global warming (not done to date).


To the contrary, the contribution of CO2 to
the green house effect is well-established.
To prove that raising the concentration of CO2
in the atmosphere will not cause global warming,
would require that you disprove the established
spectroscopic properties of the common atmospheric
gases, or that you disprove conservation of energy.

Either of those, might earn you a Nobel prize.

At issue is what other factors affect global climate
change and how. The notion that it is 'unproven'
that CO2 does, is just plain asinine.
