Magnetic Pole Reversals
The impact of magnetic pole reversals on Earth's biosphere is debated, with some linking the extinction of Neanderthals to past geomagnetic excursions. While the magnetic field has weakened by about 10% since the 1830s, the exact timing of the next reversal remains uncertain. Changes in the magnetic field could disrupt animal navigation and electronics, but the Earth has survived such events before, suggesting a long-term perspective is essential.In this clip
