Matt may be right that I haven't harangued people about climate change recently, so here goes: dude, if you're still a climate change skeptic, it's time for a rethink. When the science correspondent for Reason magazine comes over to the reality of anthropogenic global warming, it's safe to say that the skeptics have lost the debate. Not only the vast majority of the scientific community, but even most of the hard-core skeptics at conservative magazines, have abandonned the hope that we are not warming up the climate.

There's still debate about the effects of the warming, and what we should do about it. But there's not much question that it's happening. And given that our atmosphere is an extremely complicated system that we, and all of our foreseeable descendants, are utterly dependent upon for our well being, it behooves each of us to think hard about our greenhouse gas emissions, and how we might reduce them; behooves us even if no one else is doing so. Your mother was talking sense when she told you that morality doesn't get suspended because "everyone else is doing it".

No, I'm not going to tell you what you should or should not do, where you should live or what you should drive. That's not my job; it's yours. But you know how much wasteful consumption you do, particularly when compared to the poor people in other countries that global warming may flood out. I'm just saying it wouldn't kill you to think about it a little.
