| *sigh* This was going to be the panic after comtrails precipitating clouds to reduce the sunlight reaching the surface, but global warming had a scarier emotional hook. It looks like someone thinks we’ve passed peak climate change, and decided to dust off this old chestnut. |
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. |
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".
