How to demonstrate the human impact on the environment?

Is there a simple proof to demonstrate the human impact on global climate change? A common argument made by American conservatives is that humans can't possibly have a great enough impact to make a difference. Surely there's some relatively simple bit of logic that can prove our impact. Perhaps something along the lines of: "Global emissions of greenhouse gases amount of X billion tons each year, or Y trillion in the past century. Every Z billion tons of greenhouse gases increase the earth's radiative forcing by A%, each percent of which warms the earth by B degrees."
