An inconvenient truth.... or lie?

Whereas GW may or may not be a real concern, I just can't see the use of the debate in practical terms. In my mind, the fact that carbon ressources are by their nature limited (and that we may be approaching Peak Oil or even past it) trumps everything else. Moreover, knowing that most nuclear powers don't have the necessary oil in their own ground to exploit at a sufficient rate to make their oil dependent economy works should be a concern to everyone regardless of your party or country.
Link for Peak Oil: Peak oil - WikipediaYou also have to keep in mind that what our economies need is not exactly oil, but cheap oil (everyone remembers 150$/oil barrel I think so I don't really need to develop). Meaning that the tar sands of Canada and shale oil in the USA are very expensive alternatives and not viable to make the economy works. It also appears (Athabasca oil sands - Wikipedia in production) that they are cutting oil production in the tar sands as a result of the fall of oil price indicating that the price of exploiting those new sources would put a high floor on the price of oil.It's one of the reasons I think we should be getting out of oil as fast as possible as we don't know how much time it would take to transition from a carbon dependant economy to one that isn't. A failure to do so would spawn conflicts that would do far more harm than any damage Global Warming could do.Americans should have an added reason not to consume oil: lots of it finance terrorists activities or at least suspicious activities that aren't in their best interests (e.g: Middle East). Their dependency on oil also makes them weaker when negotiating with oil exporting countries, something I thought libertarians and conservatives would be most concerned about.In light of those problems, I would think GW as an interesting subject of climate study but the problems linked with the actual dependency on oil of our economies makes GW of little practical importance when making political decisions on whether we should get off of oil or not.Edited by Son, : No reason given.
