Mini Ice Age 2015-2035: Earth's Magnetic Fields Now Twisting (Video, AwesomePictures)

% of readers think this story is Fact. Add your two cents.



A compass tells you what direction is ‘North’, but have you ever wondered how it can do that? The answer has to do with something called MAGNETISM!

Every magnet produces an invisible area of influence around itself. When things made of metal or other magnets come close to this region of space, they feel a pull or a push from the magnet. Scientists call these invisible influences FIELDS. You can make magnetic fields visible to the eye by using iron chips sprinkled on a piece of paper with a magnet underneith.

On the Sun, our nearest star, you can see the same kinds of magnetic fields as they pop out of the surface of the sun. This picture shows the lines of magnetism near a sunspot.

The entire planet Earth would easily fit under the archway formed by the magnetic field loop.

We can see these loops of magnetism on the sun because very hot gases flow along them and light them up!

A compass works the way it does because Earth has a magnetic field that looks a lot like the one in a magnet. The Earth’s field is completely invisible, but it can be felt by a compass needle on the Earth’s surface, and it reaches thousands of miles out into space.

If you were to take a rocket ship into space and study the Earth’s invisible magnetic field, it wouldn’t really look like a bar magnet at all. Earth’s magnetic field gets stretched out into a comet-like shape with a tail of magnetism that stretches millions of miles behind the earth, opposite from the sun. The sun has a wind of gas that pushes the earths field from the left to the right in the picture. Scientists have studied many different parts of the Earths magnetic field and have given them names so that they can talk to one another about them. Each part is part of the vast ‘geomagnetic system’ in which many amazing things have been seen and discovered.

In your classroom, you can make a magnetic field by letting a current flow through a piece of wire wrapped around a nail. When you attach the battery, the nail becomes an ELECTROMAGNET and you can use it to lift paperclips.

The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates. The powerful magnetic field passes out through the core of the earth, passes through the crust and enters space. This picture which was created by a computer from a mathematical model, shows the solid inner core region ( inner circle) surrounded by a molten outer core (the area between the two circles). The currents flow in the outer core, and the lines of force shown in yellow, travel outwards through the rest of the earth’s interior. If the earth rotated faster, it would have a stronger magnetic field. If it had a larger liquid core it would also have a stronger magnetic field.

By the time the field has reached the surface of earth, it has weakened a lot, but it is still strong enough to keep your compass needles pointed towards one of its poles. All magnets have two POLES: a North Pole and a South Pole.

There is another thing that we know about magnets and magnetism. When you put like poles together ( South facing South or North facing North) they repell each other. You can feel this force of repulsion yourself! When you put un-like poles together (South facing North) you can feel magnetic attraction.

In the Northern Hemisphere, your compass needle points North, but if you think about it for a moment, you will discover that the magnetic pole in the Earth’s Northern Hemisphere has to be a South polarity. This is so, because the North-type magnetism of the compass needle has to be attracted by a south-type magnetism in the Earth in order to ‘seek out’ the north pole. If the Earth’s magnetism has a south-type polarity in the Northern Hemisphere, where does it have a north-type polarity? Answer, in the Southern hemisphere!

The magnetic poles of earth are not fixed on the surface, but wander quite a bit as the map shows. The pole in the Northern Hemisphere seems to be moving northwards in geographic latitude by about 10 kilometers per year, but the motion is only an averge.

On any given day, it moves erratically by many tens of meters because of changes in the currents inside earth’s core, as well as the influence of electrical currents in the ionosphere, and the changing space environment due to solar storms and winds.

During the 20th century the geomagnetic North Pole moved 1100 km, and since 1970 its rate of motion has accelerated from 9 km/year to approximately 52 km/year (2001–2007 average; see also Polar drift).

NOAA made some significant and apparently linear changes to the pole location data going back to the years 2001 through 2010. The most noticeable result of the changes that they made was an overall linear slow down of the shift during the past decade, although still at a high rate of speed. They have projected positional data through 2015 and have slowed the pace of movement each subsequent year from 30 miles (2012) to 24 miles (2015).

      Any mariner knows that the magnet north moves steadily around the true north pole. My memory may not serve me correctly here but it circles the North Pole about every 960 years.
      That’s why on a nautical chart you see the Variation of magnetic north and it also shows you how much it moves in a year so that the navigator can figure out where magnetic north is at that time.
      So….. Nothing new here folks

      There was a fellow predicting an ice age was coming and another fellow who predicted why because of the gulf oil spill. I forgot their names but it was just a few years ago and I went around debunking idiots that said global warming was coming.

      In my global warning mode I told them an ice age was coming instead.

      Clearly the North Pole has moved to the East steadily for the last ten years with Native Alaskans saying it’s evident to all who have lived there for generations. The net effect is both poles will warm and cooling will move East creating a new frozen area. One only needs to look at the weather in the North East which has become much colder and the Western U.S and Canada warming. The main problem of pole shift even a small one of 33 degrees will make Ocean levels rise for the next 39 years. I would expect New York to be under water sooner than some scientists who are predicting flooding in 2050, I believe we will see flooding in 2023 and NYC underwater in 2029. What these scientists believed was the poles movement was static but they are still moving to the East and my calculations are much closer.

      Wow! So all that Global Cooling I was taught as a child in the 1970′s was true. :roll:
