While it's obvious Global Warming exists and the various reasons why (some not the cause of humans) one has to wonder what happened to the good old ice-age that ended about 10,000 years ago. To my limited knowledge, Americans and our large SUVs weren't around then.
So what happened?
Well, some say it was from the quantity of greenhouse gases in the atmosphere. There is evidence that greenhouse gas levels fell at the start of ice ages and rose during the retreat of the ice sheets, but it is difficult to establish cause and effect. Greenhouse gas levels may also have been affected by other factors which have been proposed as causes of ice ages, such as the movement of continents and vulcanism (not from Star Trek).
Other factors include Position of the continents, variations in Earth's orbit, variations in the sun's energy output and Vulcanism (again, not the Vulcans from Star Trek).
Basically. No one thing is the cause of Global Warming today and we as pathetic humans can only control a few small variables, but even if we do so... i.e. everyone drives hybrids or electric cars, we switch to fuels not that of oil, cut down on emissions, how much would that really help? I mean shit... without all that the ice-age completely ended from... uh... Global Warming.
Seems inevitable any way you look at it and above all else, is fucking moronic to argue about it from either side of the fence.
