I know that it is extremely difficult to link human activities to climate change. The complexity of global climate is so vast that no mathmatical model could ever come close to approximating it. That said, I believe that the connection not being made between human activity and climate change is due to a construct of our limited mathmatical abilities to model such a relationship. We still work with linear relationships in modeling as it is. No one as of yet has invented a way to model exponential relationships. Although the connection can't be made consider this. Humans add 7 billion tons of CO2 to the atmosphere every year. Atmospheric CO2 concentraton increases 3% every year. Simple chemistry tells us that if you add material to a chemical reaction on one end of an equation, it will drive the reaction in the opposite direction. Although I'm comparing a simple system to a complex one, it doesn't take a leap of faith to see that as humans we do have some effect on our environment. As far as how much of an effect that is remains to be seen.
