Well, isn´t it known that the world already passed through period of catastrophes like the extinction of the dinos, the ice ages and etc? Or course it happened a looong time ago, but supposedly it did happen. In general, doomsday prophecies seem weird and wacky, but it isn´t impossible that we ( I mean perhaps our generation) would face terrible consequences about the climate changes and increased tension between several powerful nations, complicated by things like the increasing anti-semitic feeling and several other complications, many which is being discussed here at JREF. Things aren´t going well, I´m sure. I´m not the only one who is feeling that things are so screwed that it might reach a scary peak not far too many years from here.
Some argue the consequences of climate change are already upon us. There has been seriously freakish weather patterns milling around, not only with the dust in Sydney recently, but the coldest May NZ has had on record (following on from the warmest summer in January)
Politically, I dunno. I already went through the whole 'WW3 is upon us' thing last time I was on a 2012 thread, only to be told and shown the whole idea was rubbish. Readers of Alex Jones and his site infowars.com will tell you all sorts of tales about how the food is running out, how the guns are running out, how a New World Order is being established at the G-20 summit, and how the state now owns your children. And that's just for America! People like these Alex Jones aren't doing any good with their news stories. All they aim towards is breaking society down into the very dystopias they already say surround us. There is a fine balance between ignorant and being gullible, which one must walk in order to get an accurate view of their world. From what I see, we have had several near misses, and will likely have a few more. WW3 is nearish, but not nigh.
About the culmination year of all this crap being 2012... oh well, that´s another department, and we have to apply skepticism to it to avoid it´s dangers. There is a lot of people in USA stockpiling food, masks, building underground shelters, packed with water purifiers and stuff to prepare themselves for 2012 December 21st. Come on, that is ridiculous. These people´s lives are being affected directly by this madness. And it even has SONY pictures involved with their stupid viral marketing about the 2012 movie. I would be happy if Randi would write something serious about that crap and bring his opinion to the mainstream media. That would perhaps help to balance things up a bit. I personally think this is a serious issue.
These people won't be the first. The Crusades bought whole economies under.
In parallel, I would like to know for sure if the mayans/aztecs INDEED predicted the EXACT DAY of the arrival of the spaniards. Even if the europeans weren´t what they expected em to be, like gods and bla bla. If they correctly predicted a period of profound changes with their calendar, that is worth of investigating further. Why are their calendar cycle ending in 2012 and why their interpretation about profound changes at this date? My interest about it will blow away into tiny useless bits though, if I find out that they didn´t predict the exact date of the arrival of their deathbringers. I´m asking several people and searching the net and nothing concrete and academic can be found neither to confirm nor debunk this specific topic. But I have admitedly poor googling skills as I already noticed before. Maybe someone here will help me to spot it.
Unfortunately, there isn't any concrete evidence, because there isn't any concrete answer. By the time of the Spanish conquest, the Mayan empire had collapsed, and all that was left was rival city states, greatly diverse in number and style. This annoyed the Spanish during their conquests, but they deserved it, the cultural brutes

. The first attempt at conquest was done peaceably, with little resistance from chiefs who had heard all about what had happened to the Aztec. The Spanish got to each town already deserted. Then the Spanish found and attacked people, and the Maya got annoyed, and the Spanish didn't get any further then

.By this time the Maya had figured the Spanish to be bad, and so while some spared the bloodshed and surrendered, other tribes fought hard. The Spanish Conquest of Yucatan wasn't a complete extermination of the tribes there, it was a long and complicated war. I'm sure some of the smarter Mayans may have figured out the war was ending for them, but their loyalty would be to their kingdom, not to the Maya people. The Maya people were not a whole, and many city states just simply pledged themselves to the Spanish and lived for their effort. It really depends on what you mean by their own end. The Mayan nation had ended long before the arrival of the Spanish in 1511, by shipwreck.Back then the Spanish were very peaceable indeed

. I'll inquire further.
