From Op-Ed columnist Tom Friedman:

"We’ve basically decided to keep pumping greenhouse gases into Mother Nature’s operating system and take our chances that the results will be benign — even though a vast majority of scientists warn that this will not be so. Fasten your seat belts. As the environmentalist Rob Watson likes to say: “Mother Nature is just chemistry, biology and physics. That’s all she is.” You cannot sweet-talk her. You cannot spin her. You cannot tell her that the oil companies say climate change is a hoax. No, Mother Nature is going to do whatever chemistry, biology and physics dictate, and “Mother Nature always bats last, and she always bats 1.000,” says Watson. Do not mess with Mother Nature. But that is just what we’re doing."
