hookers:D, I dont think the debate is over if these climate change patterns are taking place, they should be taking place because that is what nature does. if there was no climate change then something would be wrong because the earths climate is always warming or cooling. I believe the debate is over whether climate change is human induced. from most of the data i have seen it looks like most environmentalist a skewing that data to support their agenda. the famous CO2 vs temp graph that gore displayed in his power point did not depict that CO2 actually follows warming. by the ocean temp warming more CO2 is released creating data that shows the rise and fall of CO2 along with the temperature. just one example of many... as far as humans not having effects on the environment, i think we already have. look at ddt, CFCs, tetraethyl lead, SOx, NOx, depletion of aquifers, desertification, soil erosion, etc etc....
