This is one of the best rational examinations of the issue of global warming that I have ever seen. The guy is a philosopher by training, so he knows how to break down an issue rationally. He provides a very good holistic look at this hot topic.
As Christians, we have a duty to be stewards of God’s creation, including earth itself. But we also have a duty to think critically in practically applying theological beliefs. We have a duty to the truth and to the poor. The truth is that global warming may not be bad, may not be caused by human actions, and may be beyond our control to do anything about. And the proposed policies coming from the alarmists will hurt the poorest and most vulnerable among us. These reckless and disastrous proposals have made global warming a moral issue for conservatives!
