Weakening Magnetic Field Over North America Poses Missile Accuracy Risk

Chinese military researchers have found that the magnetic field over North America is weakening rapidly, while it is strengthening over the eastern hemisphere, including China. This shift may be linked to the movement of geomagnetic poles. The magnetic field acts as a protective barrier against cosmic rays, crucial for environmental stability. Historical studies suggest that changes in magnetic field strength have been associated with the collapse of ancient civilizations, such as the Maya and those in Iran and Syria.

Magnetic North Pole Rapidly Shifts Towards Siberia.

The Earth's magnetic north pole is moving towards Siberia at an unprecedented and unpredictable rate, with experts suggesting it could reach the region by the middle of the century. The movement of the magnetic north pole is caused by the Earth's liquid outer core, which generates the planet's magnetic field. The north dip pole has been moving primarily in the same direction since 1831, but its speed has increased significantly since the 1990s. However, scientists cannot reliably predict the movement of the magnetic poles beyond a few years, so it is uncertain whether the north dip pole will reach Siberia or change course.
