What's unresolved is the why, and what to do about it without FUBARing our economy for the next few decades.  Al Gore is right, but his solutions are not practical.  Dealing with this problem is one of the most complex issues humanity has ever had to face, and no one is sure as to what to do.  Shit, we don't even know, at this point, that we can do anything to nip this in the not so longer bud...it may be that natural forces are at play here that we cannot harness.   Despite whatever we do, all it takes is one major volcanic eruption to more than undo it.  And we have no control over that.

While I would like to be be to buy an electric vehicle, it's not practical.  I need a car that can travel 100 - 200 miles at any given time at all times with minimal time to refuel or recharge...only cars powered with the internal combustion engine will do at this time.  Hybrids don't have the power I need...I am used to kicking ass on the highways when needed, and that will never change.    

Regardless of whatever your personal situation is, best you realize that GW has been occurring for at least the past couple centuries, and we are certainly a factor in that.  Personally, I have at only a few decades of life left, and my main objective is to live it to fullest, get laid as often as possible by the ladies in my circle of friends at this time, because now is the only time we have some measure of control over.  Yes, this is selfish, but I have no intention of making undue sacrifices at this point in my life unless I have assurances that it wouldn't be for naught.  No one can do that; thus, I will continue to live according to the values I always have.  As to whether there is a Star Trek future, I will just enjoy the show.  Best you live you life according to your own terms, and not let anyone else's bullshit get in the way.  You only live once!
