The ground is moving. Well, not exactly the ground you're standing on, but the invisible point that your compass depends on. For centuries, we’ve relied on a steady, reliable North Pole, but the truth is that "North" is a bit of a moving target. Actually, it's more like a runner in a sprint. If you’ve heard the term north by north pole lately, you’re likely diving into the weird, slightly alarming world of geomagnetism. It isn't just for sailors or people lost in the woods anymore. It's a massive tech headache.
It’s moving fast.
For a long time, the Magnetic North Pole hung out around Northern Canada. It didn't do much. It drifted, sure, but at a lazy pace of maybe 0 to 15 kilometers a year. Then, around the 1990s, it decided to pick up the pace. Now it’s hauling toward Siberia at roughly 50 to 60 kilometers per year. This isn't just a fun fact for a pub quiz; it’s a logistical nightmare for the World Magnetic Model (WMM).
The Chaos of a Moving North
Think about your phone. Every time you open Google Maps and see that little blue beam showing you which way you're facing, you're using the WMM. The software assumes the pole is in a certain spot. When the pole moves faster than the software updates, your "North" starts to drift.
In 2019, the situation got so "out of sync" that scientists at the National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey had to release an emergency update. They couldn't wait for the five-year scheduled refresh. The error margin was getting too wide for high-precision navigation in the Arctic.
Basically, if you’re trying to land a plane in a blizzard near the 60th parallel, you really want your "north by north pole" readings to be accurate. Even a few degrees of error can put a runway where it isn't.
Why the sudden sprint?
The Earth’s core is a mess of liquid iron and nickel. It’s a giant, churning dynamo. Dr. Phil Livermore from the University of Leeds has done some incredible work explaining this. He points to a "tussle" between two large patches of magnetic flux. One is under Canada, and one is under Siberia.
Think of it like a game of magnetic tug-of-war. For a long time, the Canadian patch was winning, keeping the pole anchored in the West. But lately, the Siberian patch has gained strength—or the Canadian patch has weakened—and the pole is being dragged across the Arctic Ocean. It's fascinating. It's also incredibly hard to predict because we can't exactly stick a camera 3,000 kilometers under the crust to see what the liquid iron is doing.
Navigation in the Age of Drift
If you’re a hiker in the Appalachian Trail, you probably won't notice. Your compass might be off by a fraction of a degree, but you'll still find the next shelter. But for the military? For commercial shipping? For the people who lay undersea cables? It’s a different story.
The aviation industry is particularly sensitive to this. Runways are named based on their magnetic heading. If a runway is pointed at 10 degrees, it’s labeled Runway 01. If the magnetic pole shifts enough that the heading becomes 21 degrees, they actually have to go out there with paint and change the name of the runway to Runway 02. This happens more often than you’d think. Fairbanks International Airport in Alaska had to do exactly this to stay in line with the shifting north by north pole data.
- Commercial Aviation: Constant recalibration of onboard Inertial Navigation Systems (INS).
- Smartphone Tech: Updating the "declination" files in your OS so your "pointing" accuracy stays true.
- Drilling Operations: Oil and gas companies use the magnetic field to steer drill bits miles underground. If the model is wrong, they miss the pocket.
The "Big Flip" Rumors
Every time the North Pole starts acting up, people start talking about a pole reversal. That’s when North becomes South and South becomes North. It’s happened hundreds of times in Earth's history. The last one was about 780,000 years ago.
Are we overdue? Some scientists say yes. Others say this current "sprint" toward Siberia is just a temporary wobble. If a full reversal did happen, it wouldn't be an overnight disaster like a Roland Emmerich movie. It would take thousands of years. But during that transition, the Earth’s magnetic shield—the thing that protects us from solar radiation—would weaken. That would be bad for our power grids. It would be worse for our satellites.
Honestly, the "north by north pole" movement we’re seeing now is probably just local turbulence in the outer core. But even "local" turbulence on a planetary scale is enough to rewrite our maps.
Is GPS the Answer?
You might think, "Who cares about magnets? We have satellites!"
It’s a fair point. GPS doesn't care where the magnetic pole is; it cares where the satellites are. But GPS is vulnerable. It can be jammed. It can be spoofed. It can fail during a massive solar flare. This is why the military still trains with magnetic compasses. It's the ultimate backup. If the satellites go dark, we still have the Earth’s field—assuming we know where the pole actually is.
The shift is forcing us to become more agile with our data. We can't just set a map and forget it for a decade. We’re moving toward "Real-Time Geomagnetic Modeling." We’re basically trying to create a weather forecast, but for the Earth's core.
Real-world impact you can see
You can actually check the "declination" for your specific zip code. If you go to the NOAA website, you can see how much "true north" differs from "magnetic north" at your front door. In some parts of the world, that gap (called magnetic declination) is changing by nearly a degree every few years. That’s huge in the world of surveying.
What You Should Actually Do
Since the north by north pole shift isn't stopping anytime soon, there are a few practical ways to handle this if you're a professional or just a serious hobbyist.
First, stop relying on paper maps that are twenty years old if you're doing serious backcountry navigation. The declination diagrams printed in the corner are likely wrong now. You need to look up the current declination for your specific area. Most modern GPS units and smartphone apps do this automatically via the WMM, but only if they are updated.
Second, if you work in any field involving drones or autonomous vehicles, understand that magnetic interference is compounded by pole drift. Calibrating your magnetometer isn't a one-time thing. It's a "before every flight" thing.

Lastly, keep an eye on the news regarding the 2025-2026 WMM update cycle. We are currently in a period of high solar activity (Solar Cycle 25), which interacts with the Earth's magnetic field. This can cause "magnetic storms" that temporarily push the north by north pole readings even further off-course.
- Update your digital tools: Ensure your navigation apps have the latest "World Magnetic Model" data.
- Check the Runway: If you're a pilot, pay attention to NOTAMs (Notices to Air Missions) regarding runway re-designations.
- Understand the Limit: Recognize that a compass is a local tool influenced by a global phenomenon that is currently in a state of flux.
The Arctic is a place of extremes, and the magnetic field is no exception. We are watching a fundamental shift in how our planet presents itself to our instruments. It's a reminder that even the "constants" in our lives—like the needle pointing North—are subject to the restless, liquid heart of the Earth. Stay updated, keep your firmware current, and always have a backup for your backup.
