Earth's Magnetic Field and this Spinning Sphere of Molten Sodium

Recommended Posts


ummm.... 10% in 170 years!?!?!

Is anyone else doing the math here?

so in another millennium solar winds could potentially decimate all life and atmosphere on Earth? 

Please tell me I'm mistaken.

I guess it won't affect any of us reading this though... so there is that.

      It is talking about the strength of the magnetic field showing a declining trend, but also skirts around the issue of what happens if the magnetic field flips.  Basically, no one knows if/when it will happen, and what/how it will affect us.  Some scientists have speculated that previous mass extinctions happened with the zero magnetic field that occurs before a flip.  But all this is conjecture.
       
      WORLDWIDE NETWORK of geomagnetic observatories monitors changes in Earth's magnetic field. At most places there has been a general decrease in the strength over the past century, typically ten percent or so. No one can say with any certainty whether this represents a fluctuation or whether it is a decrease which will eventually lead to a reversal. 
      And then you have this headline from the illustrious Daily Star UK
