Someone stated that global warming is 95 percent caused by human actions. I suppose that the dinosaurs, who were noted for there SUVs and coal-fired factories, were responsible for the last ice age. No, we humans do lots to damage the earth, and we should be ashamed of that, but global warming is not our fault. No matter how arrogant the human race has become, we will never control the forces of nature that control climate, and the world will see other ice ages before its end, with or without us.
