Summary

Story summary

The Earth's magnetic field is changing, with the South Atlantic Anomaly expanding.
The European Space Agency's Swarm mission has tracked the anomaly for over 11 years and links it to unusual core behavior.
The weakening magnetic field does not pose immediate risks to humans, but increases satellite radiation exposure and may cause malfunctions.
Scientists are investigating whether this is a temporary shift or part of a larger pole reversal.
