I find it very strang that the Mayan's should fixate on 2012 and that what we see happening in the world seem to correlate? Supposedly, the Mayan prophecy was derived from some insight about the cycles of the sun? It does appear to be getting hotter, but not because of the sun spot cycle.
The empending economic and climatic changes that are about to hit us could very easily percipitate a globa war. Miss one or two of the major grain crops.... Oil may be the cause, but eventually it will be food and water that we end up fighting for.
Of course the experts warn of rising water 50 to 100 years down the road. The danger is out there in the future ... I'm betting on climate change, emerging diseases and the hand of man; in the near term not the distant future. By the way the weather is getting really strange here in the US....
The Big astroid, it is probably like the UFOs, the controllers are keeping us in the dark for our own good. Maybe the same applies to the global warming problems? I think it has more to do with the profit motive than anything else.
Keep in mind that since we do not realy understand time, maybe the Mayan's tapped into a higher reality and got a peek at what is down the road?
