Ancient Geomagnetic Shift Poses Modern Threat to Aviation Safety and Technology
A new study analyzing the Laschamps geomagnetic excursion, which occurred 42,000 years ago, highlights significant risks for modern aviation if a similar event were to happen today. The severe weakening of Earth's magnetic shield would dramatically increase cosmic radiation exposure for passengers and crew, particularly on high-altitude polar routes. Furthermore, the event could cripple satellite-based navigation and communication systems, which are essential for global air traffic. This would force airlines to reroute flights, leading to major disruptions and posing a fundamental challenge to flight safety protocols.
