We all know that our Earth has a magnetic field. That’s why compasses work and we know that the field also helps to protect us from radiation coming from outer space. However only a few people are aware of the fact that the Earth’s north and south magnetic poles have flipped many times in the past, and appear to be getting ready to flip again.
By the way, did you know that since a compass’s north pole points north and with magnets opposites attract, then there must be a south magnetic pole up at the actual North Pole! I’ll say that again ’cause I know how strange it sounds. Up at the Earth’s actual North Pole there is a south magnetic pole, that’s why a compass points north. The reverse is also true, at the actual South Pole there is a north magnetic pole.
By measuring the slight magnetic field frozen into igneous rocks as they solidify geologists have been able to determine that the magnetic poles switch positions every couple of hundred thousand years. (Note: The real North and South poles, the axis around which the Earth rotates, are not changing, it’s only the magnetic poles that flip.) The last time the magnetic poles flipped was 720,000 years ago so we are overdue! The picture below is based on current theories on how such a reversal will take place.
Also, we know that the Earth’s field is weakening right now. Over the past 150 years, as long as we’ve been measuring it, the Earth’s field has weakened dramatically. And then there’s the South Atlantic Anomaly, a vast region stretching from South Africa to South America where the magnetic field has virtually disappeared and a new magnetic pole looks like it’s starting to pop out! Check out the actual measurements of the Earth’s magnetic field strength in the picture below.
Now a new study of the South Atlantic Anomaly has succeeded in measuring the decline in the field strength over the past 2000 years. Geophysicist John A. Tarduno of the University of Rochester along with Michael K. Watkeys of the University of KwaZulu-Natal have been able to use the archeological remains of iron age huts in the Limpopo River Valley as archeomagnetic samples.
You see, the iron age people living along the Limpopo River had the ritual of burning down their huts during times of drought as a way of ‘cleansing’ them. The heat of the fires caused the magnetic particles in the clay to lose whatever original magnetic orientation they had and then, as the clay cooled the magnetic particles would align themselves to the Earth’s magnetic field at that place and time! This left a record of the changes to the Earth’s magnetic field in South Africa that Professor Tarduno and his colleagues have been able to read. What they have found is that the magnetic field in the past has had periods of rapid decline followed by a slow return. Further evidence that the Earth’s magnetic field is entering a period of flux and perhaps a total collapse leading to a flip. If you’d like to read more about Professor Tarduno’s work click on the link below.
So how does all of this effect me, I hear you ask? Won’t I be able to use a compass the next time I go camping? Well there’s a bit more to it than that. The Earth’s magnetic field shields us from the solar wind and the radiation associated with it. As the Earth’s magnetic field weakens we can expect cancer rates, especially skin cancer to greatly increase. The solar wind can also effect both the power grid and the lifespan of satellites in orbit above the Earth. The flipping of the Earth’s magnetic field may take a couple of hundred years to complete and during that time we shall have to learn to live without its protection.
WOW just what I was searching for. Came here by searching for advice
Thanks for the Comment. Hope you’ll check out some of my other posts!

I’m impressed, I must say. Rarely do I encounter a blog that’s both equally educative and entertaining, and without a doubt, you’ve hit the nail
on the head. The issue is something which not enough folks are
speaking intelligently about. Now i’m very happy I stumbled across this in my hunt for something
concerning this.
Well thank you very much for the kind comment. I hope you’ll be back soon to check out some of my other posts and why don’t you being some friends?

Thanks for the comment however I had to edit out the link. I’m sorry but I have a strict rule–No links to outside sites I don’t control. I have had some people try to foster some pretty disgusting sites onto mine so I just simply delete all outside links. Sorry but I just don’t want to take the risk!

Grеat blog! Ⅾօ үou have ɑny recommendations foг aspiring writers?
I’m hoping tо start my oԝn blog soon Ьut I’m a ⅼittle lost on eveгything.
Ԝould ʏou advise starting with a free platform ⅼike WordPress օr ɡo fߋr ɑ paid option? Тhere are ѕo mаny options ߋut there thаt I’m
totally overwhelmed .. Any tips? Cheers!
Thanks for the comment and here are a few thoughts. Hosting your own blog means that people will only be able to view it when YOUR COMPUTER IS ON AND CONNECTED TO THE INTERNET! Yep, that’s right, if you turn off your computer when you go to sleep no one can see your blog! You can find reasonable host websites, I went with Ipage and through them bought wordpress for my blog program. It was also nice to have some expert support in the early days whenever I had a question. Really if you look at the cost over the course of a year its not that bad. Hope that helps and GOOD LUCK!

І wοuld be awesome if ʏou coulԀ ρoint mе in the direction of a good platform.
Thanks for the comment. I use wordpress and I’m quite satisfied. As for hackers, I simply don’t let anyone else have access to the site. Even in comments like yours if they add a link to some other site it gets trashed. I literally trash 30-40 comments every day of people trying to use my blog to do their advertising so I know how you feel.

There is definately a lot to learn about this subject.
I like all of the points you’ve made.
Thanks for the comment and you’re certainly right. There is a great deal yet to be learned about the Earth’s magnetic field and as soon as I hear of any new discoveries you can be certain that I will publish a post about them!
Bob L
Can I simply just say what a relief to find someone who genuinely knows
what they’re discussing on the internet. You certainly know how to bring a
problem to light and make it important. A lot more people need
to read this and understand this side of the story. I was surprised that you aren’t more

Hmm it appears like your blog ate my first comment (it was super long) so I guess I’ll just sum it up what I submitted and say,
I’m thoroughly enjoying your blog. I too am an aspiring blog
writer but I’m still new to everything. Do
you have any tips and hints for rookie blog writers?
I’d genuinely appreciate it.
Thanks for the comment. If you’re looking to start your own blog my first advice is the KISS strategy, Keep It Simple Stupid. You’ll notice I don’t have big banners or fancy animations or other distractions that can take a long time to load. Just the information I have to give along with a few pictures to illustrate the concepts. Hope that helps.
Bob L
Great post. I was checking constantly this weblog and I’m

Hey there! I know this is kinda off topic but I’d figured I’d ask.
Would you be interested in exchanging links or maybe guest authoring a
blog article or vice-versa? My blog covers a lot of the same subjects as yours and I think we could greatly benefit from
each other. If you might be interested feel free to send me
an email. I look forward to hearing from you! Wonderful blog by the way!
Thanks for the comment. I prefer to keep what goes on my blog entirely under my control. If you’d like to run one of my old posts or something maybe we could arrange something. Let me know.
Bob L

Hi this is kinda of off topic but I was wanting to know if
blogs use WYSIWYG editors or if you have to manually code
with HTML. I’m starting a blog soon but have no coding know-how so
I wanted to get advice from someone with experience.
Any help would be enormously appreciated!
I have been browsing online more than 2 hours today, yet I never found any interesting article like yours.
It is pretty worth enough for me. Personally, if all web owners and bloggers made good content
as you did, the net will be much more useful than ever before.
Thanks for the comment. I hope that you’ll check out some more of my posts. I think you’ll find them interesting as well!
Bob L
I like reading an article that can make men and women think.
Also, thank you for allowing me to comment!
