Magnetic Pole Shift causing Armageddon!
So much for those dependable compasses and charts with rocks that don't move from 1896. Who knew that the poles would shift before GPS satellites fell from the sky resulting in armageddon?
Hold onto those iPads!

Re: Magnetic Pole Shift causing Armageddon!
The problem is not with the magnetic pole. It’s with the computer model that’s used to predict the variation. These models have usually been valid for five years. This time, the 2015 model has developed some errors sooner than 2020. So the only question is “Should they update the model sooner?”
Do you care? If you’re still using paper charts, the annual change in variation indicated on the compass rose has always been an average. If you’re using an electronic chart system that allows conversion between true and magnetic bearings, you were always supposed to get software updates that corrected the model.
What’s new?

Re: Magnetic Pole Shift causing Armageddon!
That's nothing. For the GPS satellites time runs slower than on Earth, due to spacetime. They have to constantly adjust to compensate for the difference. I adore the Science Channel.

Re: Magnetic Pole Shift causing Armageddon!
Sure and the OP must be being sardonic. Why would an honest seafaring man pay the least attention to what is "reported" by UPI. I'm given to understand that their writers can't read beyond the first page of a scientific report. Their lips get tired :-)!

Re: Magnetic Pole Shift causing Armageddon!
Actually, this affects sailors at lower latitudes hardly at all, it's such a miniscule variation/declination change. But I happen to know people planning to do the NW Passage by trawler, and at 72 N., it's going to make a difference in what the compass does and old charts are going to be off.
Luckily, Canada is on the case. Magnetic declination calculator

.......what is a compass?
Someone told me the two most dangerous items to bring on board?
A passengers schedule and paper charts.

Re: Magnetic Pole Shift causing Armageddon!
If you research this you'll find that they expect the poles to reverse, in other words the North pole will be in Antarctica, some serious variation there. It was said that the last time this happened was 780,000 years ago. Add climate change to this and navigation may be the least of your problems.

Re: Magnetic Pole Shift causing Armageddon!
I seriously doubt the creditability of this article. For the magnetic pole to move from northern Canada to Siberia would be a huge change. Government alerts would be published as this would effect much more than just boats using a magnetic compass. It reads like something that would be published in the Onion. Of course, if you buy into this you could always blame it on the Russians or maybe it is President Trump's fault.

Trump hasn't mentioned it so it may be true, if he says it doesn't exist then it's happening without a doubt.

Did that person have an IQ that was only double digits? A schedule (passenger or owner) is certainly a dangerous thing but paper charts? Some may eschew paper charts but to call them dangerous is a bit silly.
