This week researchers announced that a storm is coming--the most intense solar maximum in fifty years. The prediction comes from a team led by Mausumi Dikpati of the National Center for Atmospheric Research (NCAR). "The next sunspot cycle will be 30% to 50% stronger than the previous one," she says. If correct, the years ahead could produce a burst of solar activity second only to the historic Solar Max of 1958.
Dikpati's prediction is unprecedented. In nearly-two centuries since the 11-year sunspot cycle was discovered, scientists have struggled to predict the size of future maxima—and failed. Solar maxima can be intense, as in 1958, or barely detectable, as in 1805, obeying no obvious pattern.
Establishing the mechanisms by which the solar wind enters Earth's magnetosphere is one of the biggest goals of magnetospheric physics, as it forms the basis of space weather phenomena such as magnetic storms and aurorae.
"We call them X-points or electron diffusion regions," explains plasma physicist Jack Scudder of the University of Iowa. "They're places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun's atmosphere 93 million miles away."
Observations by NASA's THEMIS spacecraft and Europe's Cluster probes suggest that these magnetic portals open and close dozens of times each day. They're typically located a few tens of thousands of kilometers from Earth where the geomagnetic field meets the onrushing solar wind. Most portals are small and short-lived; others are yawning, vast, and sustained. Tons of energetic particles can flow through the openings, heating Earth's upper atmosphere, sparking geomagnetic storms, and igniting bright polar auroras.
We have something similar here on Earth—the Great Ocean Conveyor Belt, popularized in the sci-fi movie The Day After Tomorrow. It is a network of currents that carry water and heat from ocean to ocean--see the diagram below. In the movie, the Conveyor Belt stopped and threw the world's weather into chaos.
The sun's conveyor belt is a current, not of water, but of electrically-conducting gas. It flows in a loop from the sun's equator to the poles and back again. Just as the Great Ocean Conveyor Belt controls weather on Earth, this solar conveyor belt controls weather on the sun. Specifically, it controls the sunspot cycle.
Solar physicist David Hathaway of the National Space Science & Technology Center (NSSTC) explains: "First, remember what sunspots are--tangled knots of magnetism generated by the sun's inner dynamo. A typical sunspot exists for just a few weeks. Then it decays, leaving behind a 'corpse' of weak magnetic fields."
Enter the conveyor belt.
"The top of the conveyor belt skims the surface of the sun, sweeping up the magnetic fields of old, dead sunspots. The 'corpses' are dragged down at the poles to a depth of 200,000 km where the sun's magnetic dynamo can amplify them. Once the corpses (magnetic knots) are reincarnated (amplified), they become buoyant and float back to the surface." Presto—new sunspots!
Large flares are often associated with huge ejections of mass from the Sun, although the association is not clear. These coronal mass ejections (CMEs) are balloon-shaped bursts of solar wind rising above the solar corona, expanding as they climb. Solar plasma is heated to tens of millions of degrees, and electrons, protons, and heavy nuclei are accelerated to near the speed of light. The super-heated electrons from CMEs move along the magnetic field lines faster than the solar wind can flow. Rearrangement of the magnetic field, and solar flares may result in the formation of a shock that accelerates particles ahead of the CME loop. Each CME releases up to 100 billion kg (220 billion lb) of this material, and the speed of the ejection can reach 1000 km/second (2 million mph) in some flares. Solar flares and CMEs are currently the biggest "explosions" in our solar system, roughly approaching the power in ONE BILLION hydrogen bombs!
In the first type of polar reversal that may occur in 2012, the effects on the environment would be serious, but manageable. The ocean currents would reverse, ice-caps melt, and winds and precipitation levels alter drastically. However, if the second type of polar reversal were to occur in 2012, i.e. the entire the planet flips over as well as the Poles, there would be additional energy shifts causing tectonic plates to move. This would result in devastating earthquakes and considerable volcanic activity. The impact to Earth would be similar to a major meteorite impact, causing mass extinctions of species that marked the end of the age of the dinosaurs.
Sun cycles are natural and happen every 11 years, as we have stated. The poles reverse and shift back and forth every cycle. Solar Cycle 24 is getting a lot of attention though from NASA science these days concerning the 2012 upcoming cycle of the pole shift on the sun. Solar Cycle 24 is predicted to be 50% more solar activity than normal, for some reason. It could be because there are other celestial influences this time compared to the other sun cycles that have happened in the past. If Niburu, Planet X is for real, that could have some influence. The passing of the Earth and this entire solar system through the galactic equator could have some influence, and there may be influences from within the sun itself that no one really knows much about. There are various reasons that NASA scientists are putting out as to why there might be more violence in the sun's cycles with the upcoming Sun Cycle 24 in 2012.
This was/is so important because it would offer an explanation to whether or not solar activity can affect Earth weather. Well, we have a pretty good idea of how it happens now.
These X-points or pathways offer a magnetic bridge to leach energetic material from the sun to the Earth's upper atmosphere, where energetic particles flow through on a regular basis. They enter our upper atmosphere, and then begins to circulate along our own magnetic field, allowing the planet to remain warm and hospitable.
What do you think would happen if both Earth and the Sun underwent a magnetic pole reversal at the same time during or right after solar cycle 24? This is what is unique about the year 2012.
The signs are there, the science is there. What more do you need?

March 10, 2006: It's official: Solar minimum has arrived. Sunspots have all but vanished. Solar flares are nonexistent. The sun is utterly quiet. Like the quiet before a storm.

I'm saying that if you read and understand what is going on, you will understand how an ice age happens. I think it's a sound theory when we take the new information about the so called "portals" and check it against old information we already know about 2012 and the magnetic reversal of both the Earth and the Sun.
This is Solar cycle 24, the least active in 100 years.
This is solar cycle 24, the strongest solar cycle since 1755.
Incorrect. There is no pattern to past reversals. No reason to expect a reversal. The last reversal was 780,000 years ago. There have been wider gaps and narrower gaps.
The Earth, according to scientists is due to reverse it's own magnetic field sometime in the near future.
That is nonsense. The amount of particles captured by the Earth's magnetosphere is an insignificant fraction of the amount of particles emitted by the Sun.
This is important because the Sun uses Earth as a "power sink" for these particles.
The particles were emitted. Some are captured by the magnetosphere, most are not. Flux transfer events allow a greater amount of the plasma to enter the magnetosphere. Those which are not just continue on out into the Solar System.
I'm proposing that when this happens, the Sun will become hotter for a time due to the excess energetic particles, and then cool as this will be a short term change with long term effects.
The Earth is in its present orbit due to its angular momentum and the gravitational attraction between it and the Sun.
Without strong flow of energetic particles, the Earth would be a very different place.
Propaganda like information about flux transfer events? The sunspot number is NASA propaganda?
You can believe the NASA propaganda if you want.
Most of that information is in my sources that I cited. Some of it isn't. I'm not linking it all.
As I pointed out in my first post, your sources are obsolete. The data shows they were wrong.
Every source I have says solar cycle 24 is the peak solar cycle, as I said.
Isn't that just NASA propaganda about flux transfer events? I guess you don't understand that they have nothing to do with "charge" but with magnetic field connections.
I guess you didn't read, that those magnetic pathways can pull ridiculous amounts of energetic particles through them, when they need to, did you? Additional pathways "open up" when there is enough energetic particles to provide sufficient charge.
Approximately every eight minutes, the two fields briefly merge or "reconnect," forming a portal through which particles can flow.
Why? Flux transfer events have been going on...forever, but they've been known about for a long time. Here's an article from 1979:
That's probably why the Earth is heating up this summer, and lightning storms are so common.
My original source is newer.
March 10, 2006: It's official: Solar minimum has arrived. Sunspots have all but vanished. Solar flares are nonexistent. The sun is utterly quiet.
Like the quiet before a storm.
Regardless of how it gets here, the influx of energetic particles combined with the magnetic reversal of the poles could trigger an ice age.

You're not doing my thinking for me, nor are you going to convince me your propaganda is truth. You didn't even bother linking any. Why not?

Try going outside sometime. The planet isn't right, to say otherwise at this point shows a lack of involvment in society.
It's such a complicated theory to lay out and properly source.
Despite the fact that the pictures of the Sun have been showing some pretty terrifing sun spots? The fact that they've been removed from existance while they were being discussed on ATS?
