I've done quite a bit of research lately into the Mayan calendar and December 21, 2012. One of the conclusions scientists have been able to make recently is that there is substantial evidence for the earth having experienced a geographic pole shift a few times in the past with many ancient civilizations also having recorded events that are consistent with what happens during a geographic shift of the earth's poles. Not too long ago, scientists discovered a wooly mammoth in the frozen tundra of Siberia that had been perfectly preserved in ice and they noticed something very unusual about the beast - not only had no decomposition of its body taken place in 20,000 years, it still had vegetation in its mouth with plants all around it as if it had been instantly frozen to the point of not even being able to finish chewing its food and as if the entire location of the area had changed.
They also discovered that areas where ice and snow currently cover the landscape used to once be a subtropical climate and vice versa. The deduction was made that the earth must have rotated anywhere from 30-60 degrees on its axis in order to cause the dramatic shift in climate and temperature change. Even more stunning and shocking to them was the fact that their assumptions in the past where they thought pole shifts took tens or hundreds of years to complete were wrong because they had just uncovered proof that it happened within hours. They've hypothesized that there are only two ways for which the earth could have flipped 30-60 degrees on its axis and that is another celestial object exerting its gravitational influence on the earth or some kind of gravitational energy that acted upon the earth in such a way as to rotate it.
There are some theories as to how this could have happened - there is growing acceptance and support in the scientific community for the center of the milky way galaxy harboring incredible amounts of energy in the form of gravitational waves - well, as it just so happens, our solar system will be at the center of the milky way galaxy on December 21 of this year. The other theory (a rogue celestial object moving through the solar system) is still being debated, although, there is evidence from other planets that an object did pass through the solar system a long time ago causing some of the anamolies that currently exist out there that, to this day, still has them puzzled (the asteroid belt, Saturn's rings, Neptune's and Uranus's slightly elliptical orbits, etc.).
The ancient Egyptians actually documented once that the sun did not rise or set for a period of three days and when it began to do so again, the sun rose in the west and settled in the east, suggesting something caused the earth to stop rotating and then spin the other way. Also of note lately are all of the mass bird and fish deaths, but if the earth was preparing to undergo a geographic (or even magnetic) pole shift or the earth's magnetic poles were in flux, this would certainly cause these animals' built-in homing system using the magentic poles as a compass to become screwed up to the point of losing their sense of direction - if that happened, birds and fish would experience problems they've never encountered before, including the possibility of starvation as their eco-systems are changed.
Scientists have even discovered decomposed and rotted trees in Park City, Utah that had all been slammed up against a hillside that are only found in the desert heat climate of Arizona. Not long after, they discovered evidence that a massive torrent of water thousands of feet high had rushed over the western United States long ago which created all of the beautiful landscape features we see in southern Utah and Arizona, along with fossils of marine life high in the tops of some mountains. Anyway - this whole study/research of mine into a geographic pole shift has resulted in some fascinating information. Maybe we're in for a geographic shift of the earth soon? It could certainly account for many of the prophesied events to occur in the future foretold of in scripture, that's for sure.
History is not necessarily the truth, but truth is in history.
