We now know for a fact that CO₂ levels are higher today than at any time in the last eight ice ages. Yes, for the last 650,000 years, CO₂ levels have never been as high as they are today. Further, we now know that for those eight ice ages the relationship between CO₂ and climate has remained constant. So basically, anyone who says that what’s going on with melting glaciers, rising sea levels, and super storms is completely natural could learn a thing or two from the mastodons and sabre-toothed tigers of the Early Pleistocene Era and their "completely natural" fate.

Environmentalism is just as much about "Saving the Earth" as it is about "Saving the Grandkids".
