I wonder if this has some impact on the magnetosphere, the tides and the climate.

"Some," yes, but almost certainly nothing we'd notice. The core is still spinning, it's just the differential between the crust and the core that has decreased.

I'm no planetcoreologist but I reckon a planet sized spinning blob of molten metal slowing noticeably over a mere decade might be cause for a smidge of concern?

It happens every couple decades. It’s a nothing story, cool to scientists, conspiracy bait to laymen.

So you’re saying this is all because of some US government secret experiment that has chemically castrated us all and polluted our oceans?

Have you not seen the documentary “The Core”? Scary stuff man

So you're saying I should panic and buy toilet paper?

Is the mechanism that causes this comparable to how a pendulum with a spring instead of a string goes from bouncing up and down to swinging side to side?

"Noticably" doesn't mean a lot, on a human scale, when it's 21st-century scientific equipment doing the noticing.

We do underestimate how one minor variable could turn a usual occurrence into a catastrophe. Whether that change is immediate or over a longer period of time, we could only guess.

Unfortunately, we are going to have to face the elephant in the room - eventually. Our lives are in the hands of statistical anomalies and strange nonsensical occurrences, time for us is not endless .

You wouldn’t notice from a nature standpoint, but our tech might notice it.

The reason why we have never noticed it is because during the Roman times the poles switched sides.

I forget the archeological report from maybe a decade ago but supposedly looking at the overall iron matters in old clay remains and they noticed the alignment of the iron minerals having slowly shifted when comparing them over a few hundred years.

I think it was the earliest historical confirmation after we discovered that the poles move every ones in a while a bit around.

Do you have any evidence about the poles switching times during the Roman era? As far as I was aware the last time it happened was like half a million years ago or something, which certainly was not during the Roman era.

Honestly I will have to look into it, but as I said this was over a decade ago and on some Discovery channel or History channel documentary from when they actually still showed scientific material.

So basically this information might be massively outdated or having been disproven by now. Which was why I had mentioned the date of the information / when I learnt about it.

It could have been just a sensationalist documentary and then never retracted.

There is no credible evidence for a total geomagnetic pole reversal during Roman times. The last one was at least 780,000 years ago.

There is however research that talks about localized evolution in the geomagnetic field, for example this one in Iberia

Ah thank you for the links and the second link might be what I was thinking of.

Interesting reads, even if half of it is a bit beyond my normal comprehension.

Why would it effect the tides? Tides are lunar based are they not?

Magnetic North has been wandering around a lot the last decade or so. Might be related, though doubt it's causal.

DidaskolosHermeticon t1_j642m63 wrote

It's got to be related. I'm very much not any kind of expert; but the Magnetosphere is generated by the motion of the liquid iron core, the North Pole is determined by the geometry of that motion relative to the surface, and we are measuring these processes in tandem. There may be a black-box of complex math between these two things, but I feel like it's certain they are related.

JustAPerspective t1_j64obtr wrote

It's easy to be confident when there's limited information available.

While what you're saying is highly probable based on our current understanding, these two phenomena may be related - it is not absolute. Assumption precludes, and oft forgets, discovery.

How do they know the spin of the core? (ie the pace, direction, etc)
