Earth’s Magnetic Field Decaying at an Alarming Rate

December 11, 2018 | David F. Coppedge

The biosphere depends on earth’s magnetic field, but it has been decaying rapidly for at least 1500 years.

In Spacecraft Earth: A Guide for Passengers, Dr Henry Richter describes how the story of the decay of the earth’s magnetic field caught his attention. He had read the monograph by Dr Thomas Barnes in the 1970s, and realized the implications: if the decay is true, the earth could not be billions of years old. He considered the various proposals for maintaining the field, but none of them work, he concluded. If this is a well-known fact, what do secular geophysicists have to say about it?

Throughout earth history the record shows that the field weakens before a pole reversal. Without a field we will be subject to increased cosmic ray bombardment, which will lead to higher cancer rates and increases in genetic mutations (ie, more liberals).

Exactly this guy, or folks using his work, trying to prove a young earth is laughable. As long as we have a spinning core surrounded by magma we will have a magnetic field. It will wander and poll flip and strengthen and weaken, but it’s not going anywhere, and the idea that current weakening proves a young earth is not supported.

The article might be new. The theory & assumptions behind the article, and the presentation, is not.

but it has been decaying rapidly for at least 1500 years.

That doesn't sound like a rapid decay rate. But just in case here's a bunny with a waffle...

The earth is also defended to a degree by Jupiter's magnetic field, & to a much lessor degree Saturn's magnetic field. Both dynamic i.e. waxing & waning. In fact Saturn's seems to be weakening as is the Earth's , Now whether that is coincidence or related I have no idea. Maybe no one knows yet. Additionally the sun's magnetic field also makes a considerable contribution protecting us from extrasolar system energetic particles like cosmic rays. Note the sun also produced energetic particles which strike the earth, so it helps & hurts. All of this going dynamically - changing with time sometimes reinforcing the protection maybe even at times acting against each other. Very complex & fascinating!

Me too. Gotta move for the device to know which direction. Vector or two points sets direction. Better units include a compass for navigation and line of site nav while standing still. Been using them for a long time. Of course all of this is now integrated into your smart phone or car navigation system. You can definitely navigate without the compass. Not sure how it works when the compass is give false true north information.

The vast majority of Earth's protection from galactic cosmic rays is the sun.

yes I know!

Maybe the GPS system provides magnetic declination information. That system provides rather large tables for computing position from all of those satellite fixes. Magnetic declination would add very little to that bulk, especially if it merely provided the coordinates of the instantaneous magnetic north. Maybe I should just get off my butt and read that stuff again.

[dhs12345]

Good point. I don’t think that it does it directly since the mag pole is a natural thing that can and does move.

Whenever I used the compass in a GPS unit it was for orienteering/orientating wrt north probably for paper maps. But also for taking that first step because your GPS unit requires movement to get direction. Weird. But that is the way they used to work.
