Bull****.
I have NO idea, because I don't give a crap, because it does NOT matter.
First of all, I am not sure that "climate change" is the result of human activity.
Secondly, I know that whether or not "climate change" is the result of human activity, oil will remain the life's blood of civilization for decades to come.
Thirdly, even if I drank the Gore Kool-aid, swallowed it whole, as it were, I know that if Canada ceased ALL production, and we all froze to death next winter, so that the nation and its people ceased to exist.....we would lower world-wide GHG emissions by....2%.
Fourth....climate changes, it always has changed, it always will change....deal with it. Mankind rules because of his adaptability...ADAPT, dammit.
The symbol of our stupidity is not that we are failing to sacrifice our civilization on the Alter of Al Gore's con job and giving up fossil fuels immediately...........the symbol of our stupidity is that we rebuilt New Orleans in the same place........
