Earth's magnetic north pole has shifted towards Siberia, as predicted and shown in the latest 5-year update to the World Magnetic Model (WMM).
The WMM is jointly developed by NOAA and the British Geological Survey (BGS).
"Magnetic north has been moving slowly around Canada since the 1500s but, in the past 20 years, it accelerated towards Siberia, increasing in speed every year until about five years ago, when it suddenly decelerated from 50 to 35 km per year."
