I'm not denying that CO2 can cause problems, or that humanity is changing the global climate. I'm just saying that I live in California, it's not even winter yet, and I still can't go to an Occupy San Jose rally without hearing at least two people whining about the cold. I can't wait for the effects of global warming to fully kick in.
So it doesn't matter what the effects on anyone else is so long as you get what you want? That's not real libertarianist philosophy.
