Getting back to the point of this thread.
"Seriously, though, how would a libertarian society address global warming?"
Simple enough, they would address it by exposing the scam that it is.
If you want to believe it's a scam, then by all means, seek out those who are on your side. I suppose you have evidence the Moon landings were faked as well?
You sound like a conspiracy theorist, man. Seriously, do yourself a favor. For one week - just one week - stop doing Google searches that include the word 'scam' next to 'Global Warming', and instead, just read some science journals. You can begin with Nature and Science. But if you don't want to get bogged down in the academic material, then read Scientific American.
If you want to believe it's the Gospel, then by all means, seek out those who are on your side. I suppose you have evidence that the Gulf of Tonkin incident was real as well?
You sound like a kool-aid drinker, man. Seriously, do yourself a favor. For one week - just one week - stop swallowing everything you are told by Al Gore and instead look at evidence that does not come from people who are on the government payroll.
