BB, you said "Snuff, how do you represent a colourless gas coming out of a smoke stack? No one ever said the visible smoke/water vapour coming out was CO2 - that is just your assumption. Anyway, if you've got a better way of respesenting colourless CO2 in a visual medium them I'm sure the media would live to hear it."
So they have already solved the problem of CO2! It is not coming out of the chimney stack, it is buried! Give us a break BB.
You do not tell a lie about what comes out of the stacks because it misleads simple minded people who do not understand it know what is exactly coming out. You are prepared to lie about it because it suits your argument.
