If I read the signs as mentioned by starshine correctly, there will be no doomsday but a not so gradually shift into something that wil not really make us happy.

The most likely problem will be the climate. It is said that earths rotational axis may shift, causing a massive climate change. It may also be that the global warming speeds up or causes the predicted cooling period which (either one) will affect our climate a lot.

Another possibility is the fighting over resources. Humanity is growing rapidly in numbers, resources are petering out or simply no longer sufficient, and a possible climate change may speed this process.

Anyway, doomsday is not at hand, but changes are coming, affecting all of humanity. How much it affects us depends on how hard we try to minimize or eliminate the risks of any of these things happening.

I dont place it out of the realm of possibility, I dont believe we have a clue as to the real history of this (and other) planets, and I believe there was more(different) technology on this planet, in the distant past than is being given credit.  There are too many unexplained phenomena that are simply labled mistaken data and swept under the rug by conventional thinkers if it doesn't agree with their agenda. How can we, at our stage of developement/evolution, even dare to proffess we know all? 

I dont, however think there is much u can do to prepare for it at this point. nor am I sure anything will even happen, but there is an awful lot of compelling info that at least something will happen.  As December 2012 nears, I will have a lil extra food, etc on hand. Call me paranoid or not, I believe in better safe than sorry.

I don't know if I would say I believe it entirely, I mean its human nature to predict the end of the world. 

The truth of the matter is we don't know when, if or how the world will end, after all seeing the future is the province of God not man, but when you consider all the things that could go wrong and end the world as we know it, its surprising it hasn't happened all ready. What one should consider then is not if the world's going to end, or even how, but how you will meet it. 

Its funny that when people predict the end they always estimate 60-90% of the population will die, yet all anyone does is plan for what they're going to do once they survive. 

What I'm trying to say is this if and when the world ends chances are we won't see it coming, not really anyway, so we should live as if it were ending tomorrow.

So forgive more, worry less, relax with your loved ones when you get a chance, oh and call your family. 

Incidentally I'm planning to take the first two weeks of Dec 2012 off so I can buy my Solstice and drive down to Vegas, if the world does end may as well go out in style.

However,

Matthew 24:42 States, ⁴²"Therefore be on the alert, for you do not know which day your Lord is coming. (NAS)

So, is this really December 21, 2012?

Passage Acts 2:17:
   ¹⁷And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:  (KJV)

So, what about those who are saying that it is coming?

Although each generation has is doomsdayers I have to believe part of this at least.  I am 45 years old and remember things being released to the public that have been conveniently buried these days.  In 1981, I heard of a meteor that was heading towards the earth, (it will be here in 2012 but it it actually a brown dwarf star).  You never hear of that anymore.  Before that, there was an "energy crisis".  They said if we did not do something there would be no gas for the next century.  They changed the size of cars from Lincoln Contenental size to Omni size, they lowered the speed limits from 65 to 55 (or less).  NOW we have SUV's, the speed limits are 75, and the gas prices are lining the pockets of those who make the decisions.  

Prophesy states that there will only be one more Pope, after this one, before the 'end'. If you believe it will be the end, you will be labeled as a doomsdayer, if you do not believe, you could be caught off guard.  Which do you want?
