This is what NASA says. Any problems feel free to point them out.


http://www.nasa.gov/topics/earth/features/2012.html

2012: Beginning of the End or Why the World Won't End?12.22.11 Scenes from the motion picture "2012." Courtesy Columbia Pictures. Remember the Y2K scare? It came and went without much of a whimper because of adequate planning and analysis of the situation. Impressive movie special effects aside, Dec. 21, 2012, won't be the end of the world as we know. It will, however, be another winter solstice.

Much like Y2K, 2012 has been analyzed and the science of the end of the Earth thoroughly studied. Contrary to some of the common beliefs out there, the science behind the end of the world quickly unravels when pinned down to the 2012 timeline. Below, NASA Scientists answer several questions that we're frequently asked regarding 2012.

Question (Q): Are there any threats to the Earth in 2012? Many Internet websites say the world will end in December 2012.
Answer (A): Nothing bad will happen to the Earth in 2012. Our planet has been getting along just fine for more than 4 billion years, and credible scientists worldwide know of no threat associated with 2012.

Q: What is the origin of the prediction that the world will end in 2012?
A: The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 -- hence the predicted doomsday date of December 21, 2012.

Q: Does the Mayan calendar end in December 2012?
A: Just as the calendar you have on your kitchen wall does not cease to exist after December 31, the Mayan calendar does not cease to exist on December 21, 2012. This date is the end of the Mayan long-count period but then -- just as your calendar begins again on January 1 -- another long-count period begins for the Mayan calendar.

Q: Could phenomena occur where planets align in a way that impacts Earth?
A: There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible. Each December the Earth and sun align with the approximate center of the Milky Way Galaxy but that is an annual event of no consequence.

"There apparently is a great deal of interest in celestial bodies, and their locations and trajectories at the end of the calendar year 2012. Now, I for one love a good book or movie as much as the next guy. But the stuff flying around through cyberspace, TV and the movies is not based on science. There is even a fake NASA news release out there..."
- Don Yeomans, NASA senior research scientist Q: Is there a planet or brown dwarf called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?
A: Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

Q: What is the polar shift theory? Is it true that the earth’s crust does a 180-degree rotation around the core in a matter of days if not hours?
A: A reversal in the rotation of Earth is impossible. There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the disaster websites pull a bait-and-switch to fool people. They claim a relationship between the rotation and the magnetic polarity of Earth, which does change irregularly, with a magnetic reversal taking place every 400,000 years on average. As far as we know, such a magnetic reversal doesn’t cause any harm to life on Earth. A magnetic reversal is very unlikely to happen in the next few millennia, anyway.

Earth, as seen in the Blue Marble: Next Generation collection of images, showing the color of the planet's surface in high resolution. This image shows South America from September 2004. Q: Is the Earth in danger of being hit by a meteor in 2012?
A: The Earth has always been subject to impacts by comets and asteroids, although big hits are very rare. The last big impact was 65 million years ago, and that led to the extinction of the dinosaurs. Today NASA astronomers are carrying out a survey called the Spaceguard Survey to find any large near-Earth asteroids long before they hit. We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs. All this work is done openly with the discoveries posted every day on the NASA NEO Program Office website, so you can see for yourself that nothing is predicted to hit in 2012.

Q: How do NASA scientists feel about claims of pending doomsday?
A: For any claims of disaster or dramatic changes in 2012, where is the science? Where is the evidence? There is none, and for all the fictional assertions, whether they are made in books, movies, documentaries or over the Internet, we cannot change that simple fact. There is no credible evidence for any of the assertions made in support of unusual events taking place in December 2012.

Q: Is there a danger from giant solar storms predicted for 2012?
A: Solar activity has a regular cycle, with peaks approximately every 11 years. Near these activity peaks, solar flares can cause some interruption of satellite communications, although engineers are learning how to build electronics that are protected against most solar storms. But there is no special risk associated with 2012. The next solar maximum will occur in the 2012-2014 time frame and is predicted to be an average solar cycle, no different than previous cycles throughout history.

This explanation of "HOW 2012" appears to be amiss.

Yeah, I read this post by NASA too. And while I do agree with some of it, I think they are being a little disingenuous too - especially as far as the "solar cycle" stuff. I mean, it's hard to imagine there would be something like this out there if it was just supposed to be an "average" one...

It's sad that they are so dismissive of solar storms. While there is no reason a massive storm will happen this year instead of another year, a NASA-sponsored study said that millions could die if the USA power grids went down.

I agree Rob. I love how they try to downplay it, when they themselves are the ones who let the cat out of the bag back in '09. I'm sure those of us who have been following this stuff for a while now remember this study :

Severe Space Weather--Social and Economic Impacts
http://science.nasa.gov/science-news/sc ... ceweather/

From the article :

" contemporary repetition of the Carrington Event would cause … extensive social and economic disruptions... The total economic impact in the first year alone could reach $2 trillion, some 20 times greater than the costs of a Hurricane Katrina or, to use a timelier example, a few TARPs."

But now all of a sudden, they say "Don't worry - it's no big deal." Right... they just funded that study because they weren't concerned and there was very little chance of it happening. Ok. Then they went on to describe a certain bridge they had for sale... LOL!

Many Blessings,

QuanKev

when power grids go down they are usually restored
within hours

i've been in one that went on for several days is subzero tempuatures
there were a few deaths about a dozen

this failure was caused by an ice storm not solar storm

Image

if it had been a solar storm service would have been restored faster
so many broken lines are harder to repair than generators

theres quite a record of grid failures
in modern history ... in my view none supports such a study

Well bakhti, if you have the scientific knowledge and experience to refute their claims about the potential impacts of a major solar event, than congratulations on your academic and professional achievement.

I think the key to what you said was "usually" - yes, usually when the power goes out, services are restored quickly. However, considering the fact that no truly major solar event has occured since the Solar Storm of 1859, some effects of which are described here....

(regarding the aurorae that were spawned -)
"also noteworthy were those over the Rocky Mountains that were so bright that their glow awoke gold miners, who began preparing breakfast because they thought it was morning.[3] People who happened to be awake in the northeastern US could read a newspaper by the aurora's light.[4]

Telegraph systems all over Europe and North America failed, in some cases even shocking telegraph operators.[5] Telegraph pylons threw sparks and telegraph paper spontaneously caught fire.[6] Some telegraph systems appeared to continue to send and receive messages despite having been disconnected from their power supplies.[7]"

from http://en.wikipedia.org/wiki/Solar_storm_of_1859

... I think it is somewhat foolhardy and hasty so proclaim that there is no evidence to support such a claim. Perhaps you are right. But even though I believe there is a disinformation campaign occuring at this very moment, I don't doubt for one minute the potentially devastating effects a truly major solar event (most likely a huge CME) could have on our society.


Many Blessings all,

QuanKev
