One thing not mentioned in the article I expected: Does this invite more/less harmful UV radiation? Does it change overall temperature projections?

  It means more UV radiation. The Hubble telescope for example doesn't run its UV sensors while passing through the anomaly to keep them from getting damaged.

    Wait, how? UV is spicy photons. Photons don't respond to magnetic fields, do they now?
    - throwup238 1y ago
      The anomaly brings the Van Allen Belt closer, weakening the ozone layer in the mesosphere. (On second thought the Hubble probably disables the sensor because of charged particles) It doesn’t matter much to us down here because most UV is blocked in the stratosphere.

Since the core is spinning as it always has, then dont think we humans caused this one? :) Our energy needs are always insatiable so thats why I am not a big fan of geothermal, better not mess with the balance down there

  Or geothermal uptake is nothing compared to regular volcanic activity. Earth's poles swap positions: https://en.wikipedia.org/wiki/Geomagnetic_reversal https://en.wikipedia.org/wiki/Geomagnetic_reversal > Reversal occurrences appear to be statistically random. There have been at least 183 reversals over the last 83 million years Whether this is part of one is anyone's guess.

    There was a time when we could say "our greenhouse gas emissions are nothing compared to regular biological processes," and yet here we are.

I wish these articles would go all the way showing a decent visualization of the increase. I remember something like a KML overlay that would display magnetic data on Google Earth, but it was kind of obsolete and didn't had any historical data that could be used to observe change.
