“Est-il faible?”

Le plus faible!

Your link claims that 3% of CO2 is man made but This paper from FReeper palmer says that we don't have any accurate way to measure the human CO2 contribution. He thinks 3% is too high.

The point made at that site is that water vapor is not taken into account by the warmers, thus creating the false premise that CO2 is a huge factor, when it is not. The author uses the warmers numbers, but then adds in the water vapor to show how inconsequential man's contributions really are. At least that's my take on the figures.
