2012 Doomsday Clock
Magnetic Pole Drifting
As predicted by the mayans 2012 Doomday may be just aroudn the corner! Read more below. According to scientist the Earth's north magnetic pole is drifting away from North America so fast that it could end up in Siberia within 50 years . The magnetic poles are different from geographic poles, the surface points marking the axis of Earth's rotation. The shift could mean that Alaska will lose its northern lights, or auroras, which might then be more visible in areas of Siberia and Europe. Magnetic poles have been known to migrate and reverse. "This may be part of a normal oscillation and it will eventually migrate back toward Canada," Joseph Stoner, a palaeomagnetist at Oregon State University, told a meeting of the American Geophysical Union (AGU) in San Francisco. Wandering poles Previous studies have shown that the strength of the Earth's magnetic shield has decreased 10% over the past 150 years. During the same period, the north magnetic pole wandered about 1,100km (685 miles) into the Arctic, according to the new analysis. The rate of the magnetic pole's movement has increased in the last century compared with fairly steady movement in the previous four centuries, the Oregon researchers said. The Oregon team examined the sediment record from several Arctic lakes. Since the sediments record the Earth's magnetic field at the time, scientists used carbon dating to track changes in the magnetic field. They found that the north magnetic field shifted significantly in the last thousand years. It generally migrated between northern Canada and Siberia, but has occasionally moved in other directions. Rate of change At the present rate, the north magnetic pole could swing out of northern Canada into Siberia. If that happens, Alaska could lose its northern lights, or auroras, which occur when charged particles streaming away from the Sun collide with gases in the ionosphere, causing them to glow. The north magnetic pole was first discovered in 1831 and when it was revisited in 1904, explorers found it had moved by 50km (31 miles). For centuries, navigators using compasses had to learn to deal with the difference between magnetic and geographic north. A compass needle points to the north magnetic pole, not the geographic North Pole. 2012 Doomsday Mayan Calender Pole Shift Pole Reversal Doomsday 2012 Doomsday
NASA Claims Polar Shift Due In 2012
NASA Claims Polar Shift Due In 2012You may not have noticed but during February 2001, the Sun did a magnetic polar shift. If you missed it don't worry the the next one is due again in 2012. NASA scientists who monitor the Sun say that our star's awesome magnetic field flipped 22 months ago, signaling the arrival of a solar maximum. But it wasn't so obvious to the average human. The Sun's magnetic north pole, which was in the northern hemisphere just a few months ago, now points south. It's a topsy-turvy situation, but not an unexpected one. "This always happens around the time of solar maximum," says David Hathaway, a solar physicist at the Marshall Space Flight Center. "The magnetic poles exchange places at the peak of the sunspot cycle. In fact, it's a good indication that Solar Max is really here." The Sun's magnetic poles will remain as they are now, with the north magnetic pole pointing through the Sun's southern hemisphere, until the year 2012 when they will reverse again. This transition happens, as far as we know, at the peak of every 11-year sunspot cycle -- like clockwork. Earth’s magnetic field also flips, but with less regularity. Consecutive reversals are spaced 5 thousand years to 50 million years apart. The last reversal happened 740,000 years ago. Some researchers think our planet is overdue for another one, but nobody knows exactly when the next reversal might occur. Although solar and terrestrial magnetic fields behave differently, they do have something in common: their shape. During solar minimum the Sun's field, like Earth's, resembles that of an iron bar magnet, with great closed loops near the equator and open field lines near the poles. Scientists call such a field a "dipole." The Sun's dipolar field is about as strong as a refrigerator magnet, or 50 gauss (a unit of magnetic intensity). Earth's magnetic field is 100 times weaker. When solar maximum arrives and sunspots pepper the face of the Sun, our star's magnetic field begins to change. Sunspots are places where intense magnetic loops -- hundreds of times stronger than the ambient dipole field -- poke through the photosphere. "Meridional flows on the Sun's surface carry magnetic fields from mid-latitude sunspots to the Sun's poles," explains Hathaway. "The poles end up flipping because these flows transport south-pointing magnetic flux to the north magnetic pole, and north-pointing flux to the south magnetic pole." The dipole field steadily weakens as oppositely-directed flux accumulates at the Sun's poles until, at the height of solar maximum, the magnetic poles change polarity and begin to grow in a new direction. Hathaway noticed the latest polar reversal in a "magnetic butterfly diagram." Using data collected by astronomers at the U.S. National Solar Observatory on Kitt Peak, he plotted the Sun's average magnetic field, day by day, as a function of solar latitude and time from 1975 through the present. The result is a sort of strip chart recording that reveals evolving magnetic patterns on the Sun's surface. "We call it a butterfly diagram," he says, "because sunspots make a pattern in this plot that looks like the wings of a butterfly." In the butterfly diagram, pictured below, the Sun's polar fields appear as strips of uniform color near 90 degrees latitude. When the colors change (in this case from blue to yellow or vice versa) it means the polar fields have switched signs. The ongoing changes are not confined to the space immediately around our star, Hathaway added. The Sun's magnetic field envelops the entire solar system in a bubble that scientists call the "heliosphere." The heliosphere extends 50 to 100 astronomical units (AU) beyond the orbit of Pluto. Inside it is the solar system -- outside is interstellar space. "Changes in the Sun's magnetic field are carried outward through the heliosphere by the solar wind," explains Steve Suess, another solar physicist at the Marshall Space Flight Center. "It takes about a year for disturbances to propagate all the way from the Sun to the outer bounds of the heliosphere." Because the Sun rotates (once every 27 days) solar magnetic fields corkscrew outwards in the shape of an Archimedian spiral. Far above the poles the magnetic fields twist around like a child's Slinky toy. Because of all the twists and turns, "the impact of the field reversal on the heliosphere is complicated," says Hathaway. Sunspots are sources of intense magnetic knots that spiral outwards even as the dipole field vanishes. The heliosphere doesn't simply wink out of existence when the poles flip -- there are plenty of complex magnetic structures to fill the void. Or so the theory goes.... Researchers have never seen the magnetic flip happen from the best possible point of view -- that is, from the top down. But now, the unique Ulysses spacecraft may give scientists a reality check. Ulysses, an international joint venture of the European Space Agency and NASA, was launched in 1990 to observe the solar system from very high solar latitudes. Every six years the spacecraft flies 2.2 AU over the Sun's poles. No other probe travels so far above the orbital plane of the planets. "Ulysses just passed under the Sun's south pole," says Suess, a mission co-Investigator. "Now it will loop back and fly over the north pole in the fall." "This is the most important part of our mission," he says. Ulysses last flew over the Sun's poles in 1994 and 1996, during solar minimum, and the craft made several important discoveries about cosmic rays, the solar wind, and more. "Now we get to see the Sun's poles during the other extreme: Solar Max. Our data will cover a complete solar cycle."

What makes 2012 significant is that it coincides with the alignment of the center of the Milky Way galaxy, our sun, earth, and the large planets. If it was not for this fact I would say that 2012 was just another Y2K hoax. But the astronomy makes it believeable.It looks like this gravitational cosmic tsunami could cause the sun to scorch the earth. That means that the only immediate survivors would be people in the underground cities, caves, and submarines. However, even these people may not survive too long because such an event ( gravitational surges ) might bring on earth quakes and volcanic activity, flooding, and the such. These events might collapse underground cities and caves. Huge tidal floods might flood subways on the eastern seaboard.However, if just a few did manage to survive. They would not be able to come out of their underground dwellings for some time, because the earth's protective magnetic shield may be gone.If the upper atmosphere and the earth's atmosphere was able to repair itself say in even a short period of time of one year, the survivors would face a barren world. All surface vegetation and animal life will have been destroyed. The surface of earth might perhaps look like a barren planet. The only possible source of food for those few survivors might be the ocean. Plant life and sea life might survive this event to some small degree. However, there is one problem...more than likely all the plankton will die. They live at the surface of the water and will be destroyed by the radiation.Plankton is the basic building block of life for many living organisms in the ocean. Plankton is the biggest generator of oxygen on the planet. With plankton gone and the forest gone, what is going to provide and create oxygen for the planet?It doesn't look good for the few that survive 2012. It may very well be the end of the world. Unless, a greater power comes to rescue us. But are we worth it? Man is a miserable creature that kills and destroys himself and other living things.Johann
