Earth's magnetic poles ‘about to flip’ killing MILLIONS leaving parts ‘uninhabitable'
Scientists have estimated the magnetic field that protects the Earth and is key to life has weakened by about 15% in the past 200 years.
The field has flipped many times in the Earth's history. A flip is several thousand years overdue, however, we are talking geologic time not human time. I wouldn't loose any sleep over it unless you still have a magnetic compass or are a migratory bird. |
As long as we have satellite-guided GPS, we won’t need need magnetic compasses to navigate, right? And migratory birds must have handled pole flips somehow — those flying descendants of dinosaurs have been around a long time. |
And they have suggested this could be a sign the Earth’s magnetic poles could be about to completely flip.
Our planet is a molten core that generates a huge magnetic field capable of defending it from solar storms coming the Sun.
This field extends thousands of miles into space and has a key role in every part of life on Earth, and our technology such as global communications and power networks.
Experts have warned of the danger in a new book called "The Spinning Magnet: The Electromagnetic Force that Created the Modern World and Could Destroy It".
