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
Earth's magnetic poles ‘about to flip’ killing MILLIONS leaving parts ‘uninhabitable'
