Sun and Earth

Hey folks
I've been wondering about the way the sun's been behaving lately. apparently for the first time in over 100yrs, there has been no sun spot activity.
Which might explain why it snowed in Kenya. Also here in the UK, its been the wettest August for decades.
But my main concern is, what if the suns activities has a direct link to Earths magnetic poles?
We are already observing the most bizarre magnetic activity on earth.
I'm just hoping it doesn't increase the chances of a magnetic reversal of our poles.

Something beneath the surface is changing Earth's protective magnetic field, which may leave satellites and other space assets vulnerable to high-energy radiation.
The gradual weakening of the overall magnetic field can take hundreds and even thousands of years. But smaller, more rapid fluctuations within months may leave satellites unprotected and catch scientists off guard, new research finds.
A new model uses satellite data from the past nine years to show how sudden fluid motions within the Earth's core can alter the magnetic envelope around our planet. This represents the first time that researchers have been able to detect such rapid magnetic field changes taking place over just a few months.
"There are these changes in the South Atlantic, an area where the magnetic field has the smallest envelope at one third [of what is] normal," said Mioara Mandea, a geophysicist at the GFZ German Research Center for Geosciences in Potsdam, Germany.
Even before the newly detected changes, the South Atlantic Anomaly represented a weak spot in the magnetic field — a dent in Earth's protective bubble.
Bubble bobble
The Earth's magnetic field extends about 36,000 miles (58,000 km) into space, generated from the spinning effect of the electrically-conductive core that acts something like a giant electromagnet. The field creates a tear-drop shaped bubble that has constantly shielded life on Earth against much of the high-energy radiation flowing from the sun.
The last major change in the field took place some 780,000 years ago during a magnetic reversal, although such reversals seem to occur more often on average. A flip in the north and south poles typically involves a weakening in the magnetic field, followed by a period of rapid recovery and reorganization of opposite polarity.
Some studies in recent years have suggested the next reversal might be imminent, but the jury is out on that question.
Measuring interactions between the magnetic field and the molten iron core 1,864 miles (3,000 km) down has proven difficult in the past, but the constant observations of satellites such as CHAMP and Orsted have begun to bring the picture into focus.
Electric storm
Mandea worked with Nils Olsen, a geophysicist at the University of Copenhagen in Denmark, to create a model of the fluid core that fits with the magnetic field changes detected by the satellites.
However, the rapid weakening of the magnetic field in the South Atlantic Anomaly region could signal future troubles for such satellites. Radiation storms from the sun could fry electronic equipment on satellites that suddenly lacked the protective cover of a rapidly changing magnetic field.
"For satellites, this could be a problem," Mandea told SPACE.com. "If there are magnetic storms and high-energy particles coming from the sun, the satellites could be affected and their connections could be lost."
The constant radiation bombardment from the sun blows with the solar wind to Earth, where it flows against and around the magnetic field. The effect creates the tear-drop shaped magnetosphere bubble, but even the powerful field cannot keep out all the high-energy particles.
Topsy-turvy history
A large sunspot set off a major radiation storm in 2006 that temporarily blinded some sun-watching satellites. Astronauts on the International Space Station retreated to a protected area as a precaution to avoid unnecessary radiation exposure.
The Earth's overall magnetic field has weakened at least 10 percent over the past 150 years, which could also point to an upcoming field reversal.
Mandea and Olsen hope to continue refining their model with updated observations, and perhaps to eventually help predict future changes in the Earth's magnetic field.
The study was detailed in the May online edition of the journal Nature Geoscience |

There was an article a few years back, 2, I think, that had information about the suns atmosphere and studies of the reflective values of the spheres. It was suggested that the value could be altered. The argument for the experiment was the experiment could succeed. There was no mention about the billions of lives at stake if it failed. Well whatever, I wonder if those fools did try an experiment on Sol. As you have view their continuing attempt to change the properties of Earth atmosphere it would not surprise me to learn that they did.
There is that possibility that the experiment did succeed and the results might be catastrophic.

Richard, it would truly be mind-boggling if the sun's activity could be altered....NASA has said "We found nothing to be impossible."----If you can, try to remember where you saw that information. Thanks for sharing the "possibilitiy"....just one more horrid thing to think about. |

The Sun does have a relationship with the Earth's magnetic fields and poles scientists tell us. A pole shift triggered by this? Will the magnetic core of the Earth just stop some day...
Magnetic core shields the planet.

The Earth’s magnetic field has been on the decline. Recently, the decline has become very pronounced. Using the International Geomagnetic Reference Field (IGRF) data set, the magnetic field at the equator in open ocean has declined 1.7 percent in intensity since 1980. (Geomag program, IGRF dataset, latitude 0 degrees, longitude 180 degrees, years 1980-2005, a decline from 34,824 to 34,246 nanoTesla (nT)). Whereas the entire decline over the period from 1900 to 1980 was 2.8%.
quote:
As the Earth’s magnetic field strength declines, charged particles from outer space and from the Sun will find it easier to break through the magnetic shield that protects Earth. These particles then interact with humid air in tropical, subtropical and mid-latitude environments to produce tiny water droplets that become basic building blocks in forming clouds. Increased cloud formation can result in increased global rainfall and snowfall totals. These clouds can also moderate Earth’s temperature by reflecting solar radiation.
