Statistically surely this is highly unlikely unless changes happen frequently. I mean, in the 4 billion years or whatever the Earth has been around for, it just so happens to choose to change its spin in the couple of decades in which we develop tools to measure it?
- delecti 4y agoEarth's magnetic field has reversed multiple times in the past (the graphic on Wikipedia shows ~20 in the past 5 million years). I don't think we knew why, but this could be it. Given the frequency of it, this isn't likely to be catastrophic from a biological perspective, but might cause havoc technologically. https://en.wikipedia.org/wiki/Geomagnetic_reversal https://en.wikipedia.org/wiki/Geomagnetic_reversal
- losteric 4y agoDid you read the article? The article mentions switches between super- and subrotation have occurred within just the past 50 years. So, yeah seems to happen pretty frequently. Note noting is talking about the cessation of rotation. The article is very clearly about the "strange spin" discrepancy between outer and inner core.
