Wow, Gumpokc. Hate to say it but you just about hit the nail on the head. Yeah we are affecting the weather on the earth but we surely aren't THE major cause. But I must say that we affect it more than most imagine...at least on a short term extent. When we cut the rain forests in the world and denude the edges of the oceans with our pollution it will just take a bit longer for all to turn around. Maybe you are right about the radiation thing too. More radiation means more cancers etc as well as a possible lowering of the birth rates for obvious reasons. Less people means less people to ruin the place we call home. When scientists say that there is more CO2 put into the atmosphere by one (or two or twenty) volcanes every year than people put there...well ours adds to the destruction too. But you are right. There are more things affecting the environment than just us people. LOTS more!!
