What the professor chooses to ignore:
"The earth is 4.5 billion years old and has gone through five glaciation periods. Man wasn’t around for the first four. Between each glaciation period the earth warmed up be coming hot by our standards. We started coming out of the last glaciation period about ten thousand years ago. We are not out of it yet, we still have glaciers. As we continue to come out of it, it will warm up, becoming hot, then the pendulum will swing the other way bring us a cooler climate, even another glaciation period. No world government or any other legislative body can change that. It is amazing that the once great science magazine fails to consider science instead wants to become a political rag instead of a great science magazine. Climate change is real, but faith based climate change is not."
