Nice GIF. I understand the earth field very well being a geophysicist who has done many magnetic surveys of the earth. As for whether it is not an issue remains to be seen. The poles may not just shift, but instead they could go into an intermediary transitional phase where there are no well defined poles. This has been recorded in volcanic rocks many times. But, there is probably nothing to lose any sleep over. Except telecommunications and power grids may be affected if the field fails and lets in more cosmic radiation:

Movement of North Magnetic Pole is accelerating

I’m just a pilot. This article has caused friends and family to send emails today asking, “What’s going on in Tampa?”. People on this board have had some pretty interesting responses to it today as well, on this and other threads. I don’t think it’s widely known that magnetic north moves.

‘Normal’ movement and the big shift towards a pole reversal are two separate issues with me. Runways are renumbered all the time because of it. Airport diagrams list the annual rate of change. Folks are twitchy with stuff like this since we’re getting closer to 2012 I’m guessing.

Thanks for the article.
