At the basic level it demonstrated that CO2 is a greenhouse gas

If it was first noticed 100 years ago, it's fairly safe to say that
it had been occuring for centuries before that, so how is it
mankind's fault, when the world population 300 - 400 years ago was a
tiny fraction of what it is now, and virtually none of them used
fossil fuels?

Why don't you answer the question directly yourself? Its a simple
straightforward question.

Or are you trying to avoid an annoying hole in the green argument?
