What Science states about Events in 2012 and they don't consider Mayan Prophecy?

Global warming and cooling linked to the sunspot cycle

The reversal of the poles is attributed to the harmonic cycle of the magnetic fields of the sun.





Polar reversals can be calculated precisely on the basis of the sunspot cycle theory or the magnetic field theory


A study reveals Global Positioning System receivers to be unexpectedly vulnerable to bursts of radio noise produced by solar flares, created by explosions in the Sun's atmosphere.





When solar activity peaks in 2011 and 2012, it could cause widespread disruption to aircraft navigation and emergency location systems that rely heavily on satellite navigation data


When the solar particles reach our planet, the electromagnetically-loaded particles will move in a spiral along the magnetic lines: from the magnetic north pole to the magnetic south pole and back.





Will devastation happen 2012?|||Yes, the poles will shift. No it's not from the sun. We will be in alignment with our sun and the center of the galaxy, it happens every 25,000 years. The amount of gravity and the magnetic forces will cause our poles to shift, not from the sun spots.|||Why not read a real science book? Solar activity runs in 11 year cycles. This affects snowfall rates, among other things.





The earth is constantly being bombarded by solar particles. It generates something known as auroras.|||Mayan Prophecy? Sure, their calendar ends in 2012. So what? My calendar ends on December 31 this year, it doesn't mean the world is going to end.|||The short answer is: of course not.





As you say: the fluctuations in sunspot activity are regular as the tide -- it has happened over and over in the past, and we still lived to tell about it.|||no. the mayan prophecy won't come true.|||Science does not take the supernatural into consideration. It looks at the facts, and makes determinations based on that.|||We only have a few years to see what will happen so I won't speculate. To add to your info, scientist have perceived a great loss in the earths magnetic field over the last 200 years. Magnetic fields are shifting, this could wreak havoc on our sat elite systems. That big blackout a few years back was caused by the current in the hydro lines abruptly changing to the opposite direction, say if it was flowing south, then wham, its going north. Kinda like the poles flipping.


Bee colony collapse is an ominous sign. Could it be the magnetic fields shifting so that bee's are losing their way? Its just as plausible as cell phone interference.|||Naw, the way things are going with Bush/Cheney and Iran and the middle east, they will have long since destroyed the world before then.|||The Mayans didn't make a prophecy, their calender just ended at that year. There was no explanation given, no prophesies made.





I'll leave the rest of the dribble to be refuted by others.|||it will be interesting to see if in 2012 you come back and admit you're wrong|||Devastation will happen in 2012!





It will also happen in 2013, 2014, 2015, 2016, 2017...|||"The reversal of the poles is attributed to the harmonic cycle of the magnetic fields of the sun."





I stopped reading here. Nothing but Pseudo-scientific hogwash.|||The last sunspot peak occurred in 2001. Prior to that, in 1990. In neither of those years did navigation systems go haywire.


Pole reversals happen with far less frequently. During a pole reversal, it is expected that the Van Allen Belts will be minimal or absent for a period of time, allowing more charged particles to hit the atmosphere directly, rather than channeling to the poles. Since this happens anywhere from 50,000 to 10,000,000 years apart, there is no way to say when the next will be. There is no correlation between increased extinction and pole reversals, so I'm not too worried about it. Also, people often take flights that cross into the arctic circle and are at greatly increased exposure to charged particle radiation, with no ill effects. The Van Allen belts do not eliminate charged particles, they direct them to the poles. That's why we have Aurorae, or Northern Lights.


The biggest impact would be on magnetic compasses, but we rely mostly on GPS these days.
