'Jet stream' is found below Earth's surface

A molten iron 'jet stream' is found below Earth's surface: Remarkable discovery could shed light on our planet's magnetic shield

    The jet stream was detected below the North Pole by ESA's Swarm satellites
    It lies deep within the Earth's core, 1,860 miles (3,000km) below the surface
    It is as wide as the UK and caused by liquid in core squeezing around a boundary
    Researchers say the jet stream is accelerating and could soon switch direction

Very interesting seeder.  Per the article in the Daily Mail, this "jet stream" of molten iron affects numerous aspects of Earth's physiology, including weather patterns.  The field has also been weakening by 15% in the past 200 years.  Perhaps this is the real cause of climate change.

The Earths magnetic field (not this newly discovered "jet stream") has declined over the past 200 years, but its unlikely this is the cause of increased atmospheric CO2, atmospheric pollution or mass deforestation

Kind of debunks the "Hollow Earth Theory" doesn't it.

Cool article. Looks like this could be a nice specific explanation for westward drift, as they say.

A quote from one of the authors is interesting. Specifically.

Professor Rainer Hollerback, co-author of the study, said: 'Of course, you need a force to move the liquid towards the boundary.

'This could be provided by buoyancy, or perhaps more likely from changes in the magnetic field within the core.'

It's a rather chicken and egg situation, isn't it? Movement in the outer core generates the geodynamo - but then the geodynamo governs movement in the outer core. It fits well with the "self-exciting dynamo" aspect of the core that's been hypothesized. However, the force necessary to move a 420 km jet of molten iron seems well above the magnetic forces generated by the core. 10s of microteslas at the surface...stronger below...but even so...

I just hope someone doesn't try to do something weird, like running a core pipe 2000 miles beneath.

The potential destruction would be, uh, bad.
Thankfully, it's so very far down.
