The Earth’s magnetic field is changing at an increasing rate, throwing off airports and altering the aurora borealis.
The changes and its effect on ordinary compasses could mean the difference between homeward bound and hopelessly lost.
Earth’s northernmost magnetic point — or magnetic north — is distinct from its geographic North Pole, and scientists have long known that the magnetic poles are on the move.
But the magnetic poles have been moving faster lately, sliding towards Siberia at 34 miles per year at a speed that’s accelerated 36 percent over the last 10 years, according to the United States Geological Survey, or USGS.
“At Washington D.C., the compass points 10 degrees to the west of true north,” Jeffrey Love, USGS advisor for geomagnetic research, told FoxNews.com. “And this is increasing at Washington at a rate of about 1/10 of a degree per year.”

My comment:
Jesus said there would be great signs from heaven just before He returns to Earth.
Luke 21:11
There will be great earthquakes, famines and pestilences in various places, and fearful events and great signs from heaven.
Little could Jesus have explained to his students about the magnetic shield. How would they have understood? Today we know. And we have no excuse for not understanding. Let the reader understand.

Ivar,
Question: How do you know that a change in the location of the magnetic north pole is one of the things that Jesus was referring to in Luke 21:11?
As far as I can tell, your comment is just speculation.
